[0004] Air conditioning devices are sometimes required to reduce their power consumption. Summary of the invention

[0005] The present invention provides an air conditioning device capable of reducing power consumption.

[0006] An air conditioning device according to one embodiment of the present invention comprises an indoor unit and a control unit. The control unit performs air conditioning operation at a set temperature set by a user. The indoor unit comprises a wind direction plate and a biosensor. The wind direction plate adjusts the wind direction of air-conditioned air blown into the room. The biosensor detects the position of a living body in the room. The control unit performs control in a first mode so that the wind direction plate is oriented so that the wind blows toward the position of the living body detected by the biosensor, and performs cooling operation or dehumidification operation at a target temperature higher than the set temperature.

[0007] Biometric sensors include radar.

[0008] When a plurality of living bodies are detected by the living body sensor, the control unit identifies a living body that satisfies a predetermined condition among the plurality of living bodies, and controls the wind direction plate in the first mode so that wind blows toward the position of the identified living body.

[0009] When the number of living bodies detected by the biological sensor exceeds a predetermined number, the control unit switches from the first mode to the second mode and performs control in the second mode so as to perform cooling operation or dehumidification operation at a set temperature.

[0010] When a plurality of living organisms are detected by the living organism sensor, the control unit switches from the first mode to the third mode, wherein the third mode determines the directional range in which the plurality of living organisms exist, swings the wind direction plate within the directional range, and controls in the third mode so as to perform cooling operation or dehumidification operation at a target temperature higher than the set temperature.

[0011] The air conditioning device includes an operation terminal for sending a command to a control unit. The operation terminal includes a display unit capable of displaying a set temperature.

[0016] The operation terminal can receive the amount of clothing being worn, and the control unit determines the air volume based on information related to the amount of clothing being worn sent from the operation terminal, and controls in the first mode so as to perform cooling operation or dehumidification operation with the determined air volume.

[0017] The control unit determines the air volume based on the distance from the indoor unit to the living body detected by the living body sensor, and performs control in the first mode so as to perform cooling operation or dehumidification operation with the determined air volume.

[0018] In the fourth mode, the control unit controls the wind direction plate to face such that wind blows toward the position of the living body detected by the living body sensor, and performs heating operation at a target temperature lower than the set temperature.

[0019] In the fourth mode, the control unit controls the wind direction plate so as to face the wind toward the legs of the living body and performs heating operation at the target temperature.

[0020] The air conditioner of another embodiment of the present invention comprises an indoor unit, a control unit and an outdoor unit.

As a result, the comfort of the living body in the room can be dynamically improved, and the power consumption of the air conditioning device can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] Hereinafter, embodiments of the air conditioning apparatus according to the present invention will be described with reference to the drawings.

[0045] (Implementation Method)

[0046] The air conditioning device of the embodiment can be Figure 1 As shown. Figure 1 This is a block diagram showing a schematic configuration of an air conditioning device.

[0047] The air conditioning device 1 has an operation terminal 94a, an indoor unit 10, and an outdoor unit 100. The indoor unit 10 is arranged in the room RM, and the outdoor unit 100 is arranged outdoors. The operation terminal 94a receives an operation instruction from the biological body CR present in the indoor RM, and sends an instruction to the indoor unit 10 according to the received operation instruction. The operation terminal 94a is, for example, a remote controller. In addition, the operation terminal 94a can be, for example, a portable terminal device such as a smart phone or a tablet terminal device, or a personal computer, etc. The operation terminal 94a can also send instructions to the indoor unit 10 via a network, a server connected to the network, etc. The operation terminal 94a can also have a button for indicating a set temperature. The button for indicating a set temperature can be a physical button or a button of a display object displayed on a screen.

[0048] In this specification, the set temperature refers to a temperature instructed to the air conditioner 1 via the operation terminal 94a. The target temperature refers to a temperature that is a control target of the air conditioner 1 for the air sucked from the room RM.

[0049] The indoor unit 10 has a biosensor 2, a control unit 3, a wind vane 4, a wind vane 5, a room temperature sensor 7, and a body surface temperature sensor 8. The outdoor unit 100 has a control unit 103. The control unit 3 and the control unit 103 cooperate with each other to perform air conditioning processing according to the instructions received by the indoor unit 10 from the operation terminal 94a. That is, the control unit 3 and the control unit 103 can perform air conditioning operation at a set temperature set by the user via the operation terminal 94a. At the same time, the control unit 3 performs control using the biosensor 2. The biosensor CR is, for example, a human being, in which case the biosensor 2 can also be a human body sensor. The biosensor 2 is, for example, a radar. The control unit 3 has a tracking control mode, a power-saving cooling mode (a first mode), a power-saving heating mode (a fourth mode), and a normal control mode (a second mode) as control modes.

[0050] Alternatively, the control unit 3 may mainly perform air conditioning. In this case, the outdoor unit 100 may be configured without the control unit 103. Alternatively, the control unit 103 may mainly perform air conditioning. In this case, the outdoor unit 100 may be configured without the control unit 3.

[0051] The tracking control mode is a mode for performing tracking control of the living body CR using the biosensor 2. The tracking control of the living body includes control performed while tracking the position of the living body CR. The power-saving cooling mode is a mode for performing cooling operation including tracking control of the living body using the biosensor 2 and power-saving control. The power-saving heating mode is a mode for performing heating operation including tracking control of the living body using the biosensor 2 and power-saving control. The normal control mode is a mode for performing normal control without using the biosensor 2.

[0052] In the power-saving cooling mode, the biosensor 2 detects the position of the biomass CR in the room RM under the control of the control unit 3. The control unit 3 tracks the position of the detected biomass CR and controls the wind deflectors 4 and 5 to move in the direction of blowing toward the position of the detected biomass CR. That is, the wind deflectors are oriented so that the wind blows toward the position of the biomass CR. At this time, the room temperature sensor 7 detects the temperature of the air in the room RM under the control of the control unit 3. The air conditioner 1 corrects the target temperature to a temperature higher than the set temperature indicated by the operation terminal 94a. The air conditioner 1 performs cooling operation so that the temperature of the air in the room RM detected by the room temperature sensor 7 approaches the target temperature.

[0053] Thus, when the living body CR existing in the room RM moves in the room RM, the conditioned air from the indoor unit 10 can be blown onto the living body CR to effectively reduce the perceived temperature of the living body, and the air conditioning device 1 can perform cooling operation at an operating load lower than the operating load corresponding to the set temperature. For example, if the living body sensor 2 is a radar, the tracking performance of the control can be easily improved. That is, the conditioned air can be blown onto the living body CR in real time, and the comfort is unlikely to be damaged. As a result, the comfort of the living body CR existing in the room RM can be dynamically improved, and the power consumption of the air conditioning device 1 can be reduced.

[0054] Furthermore, in the power-saving cooling mode, the control of directing the wind deflector to the position where the wind blows toward the organism CR may include, in addition to the control of directing the wind deflector exactly toward the organism CR, the control of directing the wind deflector to the direction where the wind blows toward the organism CR even if the wind deflector is not exactly toward the organism CR. The control of directing the wind deflector to the position where the wind blows toward the organism CR may include, for example, the following control: dividing the room into about 3 to 4 areas, determining in which area the organism CR is located, and sending air toward that area (a larger range). The control of directing the wind deflector to the position where the wind blows toward the organism CR may include the control of swinging the wind deflector left and right within a range where the wind does not deviate from the position of the organism CR as the center.

[0055] In the power-saving heating mode, the biosensor 2 detects the position of the biomass CR in the room RM under the control of the control unit 3. The control unit 3 tracks the detected position of the biomass CR and controls the wind deflectors 4 and 5 to move in the direction of blowing toward the detected foot position of the biomass CR. That is, the wind deflectors are oriented so that the wind blows toward the position of the biomass CR. At this time, the room temperature sensor 7 detects the temperature of the air in the room RM under the control of the control unit 3. The air conditioner 1 corrects the target temperature to a temperature lower than the set temperature indicated by the operation terminal 94a. The air conditioner 1 performs heating operation so that the temperature of the air in the room RM detected by the room temperature sensor 7 approaches the target temperature.

[0056] Thus, when the living body CR existing in the room RM moves in the room RM, the conditioned air from the indoor unit 10 reaches the feet of the living body CR, and the living body CR is heated from the feet to effectively increase the body temperature of the living body, and the air conditioning device 1 can perform heating operation at an operating load lower than the operating load corresponding to the set temperature. For example, if the living body sensor 2 is a radar, the tracking performance of the control can be easily improved. That is, the conditioned air can reach the feet of the living body CR in real time, and the comfort is unlikely to be damaged. As a result, the comfort of the living body CR existing in the room RM can be dynamically improved, and the power consumption of the air conditioning device 1 can be reduced.

[0057] Furthermore, in the power-saving heating mode, the control of directing the wind deflector so that the wind blows toward the feet of the living body CR may include, in addition to the control of directing the wind deflector exactly toward the feet of the living body CR, the control of directing the wind deflector so that the wind blows toward the feet of the living body CR even if the wind deflector is not exactly toward the feet of the living body CR. The control of directing the wind deflector so that the wind blows toward the feet of the living body CR may include, for example, the following control: dividing the room into about 3 to 4 areas, determining in which area the living body CR is located, and sending air toward that area (a larger range). The control of directing the wind deflector so that the wind blows toward the feet of the living body CR may also include the control of swinging the wind deflector left and right within a range where the wind does not deviate with the feet of the living body CR as the center.

[0058] In the energy-saving cooling mode or the energy-saving heating mode, the body surface temperature sensor 8 can also detect the temperature (body surface temperature) of the surface of the biological body CR. Under the control of the control unit 3, the body surface temperature sensor 8 can scan the area near the position of the biological body CR in the room RM and obtain temperature scanning data. The body surface temperature sensor 8 is, for example, an infrared sensor. The control unit 3 can cut out the position of the biological body CR in the temperature scanning data and calculate the body surface temperature based on the temperature data of the cut-out part. In this way, the control unit 3 can perform control corresponding to the body surface temperature.

[0059] In control modes other than the power-saving cooling mode and the power-saving heating mode (for example, the tracking control mode and the normal control mode), the air-conditioning apparatus 1 performs cooling operation or heating operation at the set temperature instructed by the operation terminal 94 a .

[0060] Specifically, the indoor unit 10 performs air conditioning on the air sucked from the room RM through the suction port, and blows the air-conditioned air after the air conditioning toward the room RM. The air conditioning process includes, for example, heat absorption process, heating process, dehumidification process, humidification process, air supply process, and air cleaning process. The heat absorption process, heating process, dehumidification process, humidification process, air supply process, and air cleaning process correspond to the cooling operation mode, heating operation mode, dehumidification operation mode, humidification operation mode, air supply operation mode, and air cleaning operation mode, which are the operation modes (main operation modes) of the air conditioner 1, respectively.

[0061] In addition, the main operation mode can be arbitrarily combined with the control mode (for example, the tracking control mode, the normal control mode, the power-saving cooling mode, and the power-saving heating mode). The air conditioner 1 can adopt any one of the cooling operation mode, the heating operation mode, the dehumidification operation mode, the humidification operation mode, the air supply operation mode, and the air cleaning operation mode in the tracking control mode. The same is true for the normal control mode. The air conditioner 1 can adopt the cooling operation mode in the power-saving cooling mode. The air conditioner 1 can adopt the heating operation mode in the power-saving heating mode.

[0062] The humidification process may be omitted in the air conditioning process. In this case, the humidification operation mode may be omitted as the operation mode of the air conditioning device 1.

[0063] The air conditioning device 1 has a windless mode on and a windless mode off as an auxiliary operation mode. The auxiliary operation mode can be arbitrarily combined with a control mode (for example, a tracking control mode, a normal control mode, a power-saving cooling mode, and a power-saving heating mode), and can also be arbitrarily combined with a main operation mode. When the windless mode is on, when air-conditioned air is blown out from the indoor unit 10, two flow rates of wind are mixed, thereby generating turbulence that spreads over a wide range and generating natural wind (so-called windless wind).

[0064] The air conditioner 1 may also have an automatic operation mode as an operation mode. The air conditioner 1 detects the temperature of the indoor RM through the room temperature sensor 7. The room temperature sensor 7 is provided at a location where the air of the indoor RM can be detected. The room temperature sensor 7 may also be provided near the suction port to detect the temperature of the air sucked from the indoor RM through the suction port. In the automatic operation mode, if the temperature detected by the room temperature sensor 7 is higher than the set temperature, the air conditioner 1 operates in the heating operation mode, and if the temperature detected by the room temperature sensor 7 is lower than the set temperature, the air conditioner 1 operates in the heating operation mode.

[0065] Air cleaning can be performed in various ways, such as an electric dust deposition method or a fan method. In the electric dust deposition method, dust-charged air is passed through a filter, and the filter charged with the opposite polarity adsorbs the dust, thereby removing dust from the air. In the fan method, air is passed through a filter with a finer mesh, such as a HEPA filter, and the filter is used to filter the dust, thereby removing dust from the air. Alternatively, air cleaning can be performed by releasing ions into the air, or by irradiating ultraviolet rays (UV) into the housing of the air conditioner 1 for sterilization.

[0066] In the air conditioning device 1, the indoor unit 10 includes a fan 23, a heat exchanger 22, a ventilation component 6, and a receiving device 94 in addition to the biosensor 2, the control unit 3, the wind vane 4, the wind vane 5, the room temperature sensor 7, and the body surface temperature sensor 8. The control unit 3 includes a control device 80, a drive circuit 81, a drive circuit 82, a drive circuit 83, a fan motor 84, a wind vane motor 85, a wind vane motor 86, and a switching motor 87. The outdoor unit 100 includes a fan 123, a heat exchanger 122, a four-way valve 124, a compressor 125, and a control unit 103. The control unit 103 includes a control device 180, a drive circuit 181, a drive circuit 182, a drive circuit 183, a fan motor 184, a switching motor 185, and a motor 186.

[0067] In the indoor unit 10, the fan 23 is arranged near the heat exchanger 22. The fan 23 guides the air sucked from the room RM through the suction port of the indoor unit 10 to the heat exchanger 22, and guides the conditioned air after the heat exchange by the heat exchanger 22 to the blow-out port of the indoor unit 10. The control unit 3 drives the fan motor 84 through the drive circuit 81 to rotate the fan 23 around the rotation axis. The control unit 3 can change the rotation speed of the fan 23.

[0068] The heat exchanger 22 can adopt various structures. For example, the heat exchanger 22 includes a plurality of fins and a refrigerant circuit (not shown) connected thereto. The refrigerant circuit passes near the plurality of fins, and the plurality of fins are in thermal contact with the refrigerant circuit. The heat exchanger 22 exchanges heat between the refrigerant and the air sucked from the indoor RM.

[0069] In the outdoor unit 100, the fan 123 is arranged near the heat exchanger 122. The fan 123 rotates according to the control of the control unit 103. Thus, the fan 123 guides the outside air to the heat exchanger 122, and discharges the outside air after the heat exchange by the heat exchanger 122 to the outside of the outdoor unit 100. The control unit 103 drives the fan motor 184 through the drive circuit 181 to rotate the fan 123 around the rotation axis. The control unit 103 can change the rotation speed of the fan 123 through the control unit 103.

[0070] The heat exchanger 122 can have various structures. For example, the heat exchanger 122 includes a plurality of fins and a refrigerant circuit connected thereto. The refrigerant circuit passes near the plurality of fins, and the plurality of fins are in thermal contact with the refrigerant circuit. The heat exchanger 122 exchanges heat between the refrigerant and the outside air.

[0071] The four-way valve 124 is disposed in the refrigerant circuit. The four-way valve 124 can switch the flow path of the refrigerant in the refrigerant circuit between the cooling side and the heating side according to the control of the control unit 103. The control unit 103 drives the switching motor 185 through the drive circuit 182 to switch the four-way valve 124 between the cooling side and the heating side. The control unit 3 can switch the four-way valve 124 between the cooling side and the heating side via the control unit 103.

[0072] The compressor 125 is arranged in the refrigerant circuit. The compressor 125 compresses the refrigerant and sends it into the refrigerant circuit according to the control of the control unit 3. The control unit 103 drives the motor 186 through the drive circuit 183 to make the compressor 125 perform a cycle operation of compressing the refrigerant. The control unit 3 can change the rotation speed of the compressor 125 (the number of executions of the compression cycle per unit time) through the control unit 103.

[0073] In cooling operation and heating operation, the higher the rotation speed of the compressor 125 (or the higher the driving frequency), the higher the operating load of the air-conditioning apparatus 1 becomes, and the higher the power consumption of the air-conditioning apparatus 1 becomes.

[0074] For example, the air conditioner 1 switches the four-way valve 124 to the cooling side when (control mode, operation mode) = (normal control mode, cooling operation mode) through the control unit 3 and the control unit 103. The air conditioner 1 determines the driving frequency of the compressor 125 to be the first driving frequency based on the temperature difference between the set temperature indicated by the operation terminal 94a and the indoor temperature through the control unit 3 and the control unit 103. The air conditioner 1 controls the compressor 125 to operate at the first driving frequency, while performing heat absorption processing through the heat exchanger 22, so that the refrigerant absorbs heat from the air in the room RM, and blows the conditioned air after the heat absorption into the room RM. Alternatively, the air conditioner 1 determines the rotation speed of the compressor 125 to be the first rotation speed corresponding to the set temperature indicated by the operation terminal 94a. The air conditioner 1 controls the compressor 125 to operate at the first rotation speed, while performing heat absorption processing through the heat exchanger 22, so that the refrigerant absorbs heat from the air in the room RM, and blows the conditioned air after the heat absorption into the room RM. Heat exchanger 122 performs heat dissipation processing, and releases the heat absorbed by the refrigerant to the outside air.

[0075] Alternatively, the air conditioner 1 switches the four-way valve 124 to the cooling side when (control mode, operation mode) = (power-saving cooling mode, cooling operation mode) through the control unit 3 and the control unit 103. The air conditioner 1 determines the driving frequency of the compressor 125 to be a second driving frequency based on a temperature difference smaller than the temperature difference between the set temperature indicated by the operation terminal 94a and the indoor temperature through the control unit 3 and the control unit 103. The second driving frequency is lower than the first driving frequency. The air conditioner 1 controls the compressor 125 to operate at the second driving frequency while performing heat absorption processing through the heat exchanger 22 so that the refrigerant absorbs heat from the air in the room RM and blows the air-conditioned air after heat absorption into the room RM. Alternatively, the air conditioner 1 determines the rotation speed of the compressor 125 to be a second rotation speed corresponding to a temperature higher than the set temperature indicated by the operation terminal 94a. The second rotation speed is lower than the first rotation speed. The air conditioner 1 controls the compressor 125 to operate at the second speed, and performs heat absorption processing through the heat exchanger 22, so that the refrigerant absorbs heat from the air in the room RM, and blows the conditioned air after the heat absorption into the room RM. The heat exchanger 122 performs heat dissipation processing, and releases the heat absorbed by the refrigerant to the outside air.

[0076] When (control mode, operation mode) = (power-saving cooling mode, cooling operation mode), the compressor 125 is controlled to operate at a lower driving frequency than when (control mode, operation mode) = (normal control mode, cooling operation mode), so that the power consumption of the air-conditioning device 1 can be further reduced. Alternatively, since the compressor 125 is controlled to operate at a lower rotation speed, the power consumption of the air-conditioning device 1 can be further reduced.

[0077] Alternatively, the air conditioner 1 switches the four-way valve 124 to the heating side when (control mode, operation mode) = (normal control mode, heating operation mode) through the control unit 3 and the control unit 103. The air conditioner 1 determines the driving frequency of the compressor 125 to be the third driving frequency based on the temperature difference between the set temperature indicated by the operation terminal 94a and the indoor temperature through the control unit 3 and the control unit 103. The air conditioner 1 controls the compressor 125 to operate at the third driving frequency, while performing heat absorption processing through the heat exchanger 122, so that the refrigerant absorbs heat from the outside air. Alternatively, the air conditioner 1 determines the rotation speed of the compressor 125 to be the third rotation speed corresponding to the set temperature indicated by the operation terminal 94a. The air conditioner 1 controls the compressor 125 to operate at the third rotation speed, while performing heat absorption processing through the heat exchanger 122, so that the refrigerant absorbs heat from the outside air. The heat exchanger 22 performs a heating process, and the air in the room RM is heated by the heat absorbed by the refrigerant, and the heated conditioned air is blown into the room RM.

[0078] Alternatively, the air conditioner 1 switches the four-way valve 124 to the heating side when (control mode, operation mode) = (power-saving heating mode, heating operation mode) through the control unit 3 and the control unit 103. The air conditioner 1 determines the driving frequency of the compressor 125 to be the fourth driving frequency based on a temperature difference smaller than the temperature difference between the set temperature indicated by the operation terminal 94a and the indoor temperature through the control unit 3 and the control unit 103. The fourth driving frequency is lower than the third driving frequency. The air conditioner 1 controls the compressor 125 to operate at the fourth driving frequency while performing heat absorption processing through the heat exchanger 122 so that the refrigerant absorbs heat from the outside air. Alternatively, the air conditioner 1 determines the rotation speed of the compressor 125 to be the fourth rotation speed corresponding to a temperature lower than the set temperature indicated by the operation terminal 94a. The fourth rotation speed is lower than the third rotation speed. The air conditioner 1 controls the compressor 125 to operate at the fourth rotation speed while performing heat absorption processing through the heat exchanger 122 so that the refrigerant absorbs heat from the outside air. The heat exchanger 22 performs a heating process, and the air in the room RM is heated by the heat absorbed by the refrigerant, and the heated conditioned air is blown into the room RM.

[0079] When (control mode, operation mode) = (power-saving heating mode, heating operation mode), the compressor 125 is controlled to operate at a lower driving frequency than when (control mode, operation mode) = (normal control mode, heating operation mode), so that the power consumption of the air-conditioning device 1 can be further reduced. Alternatively, since the compressor 125 is controlled to operate at a lower rotation speed, the power consumption of the air-conditioning device 1 can be further reduced.

[0080] The wind deflectors 4 and 5 adjust the wind direction of the conditioned air blown into the room RM respectively. Wind direction refers to the direction of the wind. In this specification, the control unit 3 directly controls the direction in which the wind deflectors 4 and 5 are facing, but the direction in which the wind deflectors 4 and 5 are facing and the direction (wind direction) of the wind immediately after being blown out from the outlet of the indoor unit 10 are treated as roughly the same direction. That is, the wind deflectors 4 and 5 can adjust the wind direction by their directions, and the control unit 3 can control the wind direction by controlling the directions of the wind deflectors 4 and 5. In addition, the directions of the plurality of wind deflectors 4 and 5 can be controlled separately. Thus, it is possible to blow out wind with the wind direction aligned in one direction from the outlet of the indoor unit 10 as a whole, and it is also possible to blow out two or more winds with different wind directions from two or more areas in the outlet of the indoor unit 10 divided by a plurality of wind deflectors 4 and 5.

[0081] The wind direction plate 4 can be switched between a closed position and an open position. When the wind direction plate 4 is switched to the closed position, the air outlet is closed. When the wind direction plate 4 is switched to the open position, the air outlet is opened. When the air outlet is opened, the wind direction plates 4 and 5 adjust the wind direction of the air-conditioned air blown into the room RM. The wind direction plate 4 adjusts the wind direction of the air-conditioned air in the up-down direction. The wind direction plate 5 adjusts the wind direction of the air-conditioned air in the left-right direction.

[0082] For example, the wind deflectors 4 and 5 can be Figure 2 to Figure 4 As shown. Figure 2 It is a cross-sectional view showing the structure of the indoor unit 10, and shows a state where the air directing plate 4 is in a closed position. Figure 3 It is a cross-sectional view showing the structure and operation of the indoor unit 10, and shows a state where the wind direction plate 4 is in the open position. Figure 4 1 is a perspective view showing the structure and operation of the indoor unit 10, showing the state where the wind deflector 4 is in the open position. Hereinafter, the long side direction of the indoor unit 10 is set as the X direction, the height direction of the indoor unit 10 is set as the Z direction, and the direction perpendicular to the X direction and the Z direction is set as the Y direction.

[0083] like Figure 2 to Figure 4 As shown, the indoor unit 10 has Figure 1 In addition to the illustrated configuration, the housing 21 and the filter 24 are also included.

[0084] The housing 21 is formed in a substantially rectangular parallelepiped shape extending along the X direction. In addition, the housing 21 may also be formed in other shapes. The housing 21 is, for example, mounted on a wall of the room RM. The housing 21 has an upper surface 21a and a lower surface 21b. The upper surface 21a is provided at or near the upper end of the housing 21 and faces substantially upward. The lower surface 21b is provided at or near the lower end of the housing 21 and faces substantially downward.

[0085] The housing 21 is provided with a ventilation passage 31, an inlet 32, and an outlet 33. The ventilation passage 31 is provided inside the housing 21. The inlet 32 ​​opens, for example, on the upper surface 21a of the housing 21. The outlet 33 opens, for example, on the lower surface 21b of the housing 21. The inlet 32 ​​and the outlet 33 may also open in other parts of the housing 21.

[0086] The indoor unit 10 allows wind to pass through the ventilation path 31. Wind is the flow of gas such as air. The suction port 32 is provided at one end of the ventilation path 31, and the ventilation path 31 is connected to the outside of the indoor unit 10. The blow-out port 33 is provided at the other end of the ventilation path 31, and the ventilation path 31 is connected to the outside of the indoor unit 10. In other words, the ventilation path 31 is provided between the suction port 32 and the blow-out port 33 inside the housing 21.

[0087] The heat exchanger 22 is provided in the ventilation passage 31. The heat exchanger 22 exchanges heat with surrounding air in the ventilation passage 31. Thus, the heat exchanger 22 cools the air flowing in the ventilation passage 31 during cooling operation, and heats the air flowing in the ventilation passage 31 during heating operation.

[0088] The fan 23 is provided in the ventilation passage 31. The fan 23 rotates around the rotation axis Axf extending along the X direction, thereby conveying wind from the suction port 32 to the blow-out port 33 in the ventilation passage 31. Thus, the indoor unit 10 inhales indoor air from the suction port 32 into the ventilation passage 31, and blows out the air (wind) of the ventilation passage 31 from the blow-out port 33. Therefore, in this specification, the side of the ventilation passage 31 close to the suction port 32 is referred to as the upstream, and the side close to the blow-out port 33 is referred to as the downstream.

[0089] The fan 23 is located downstream of the heat exchanger 22. Therefore, when the fan 23 generates wind, the air sucked from the suction port 32 passes through the fins of the heat exchanger 22. Thus, the air flowing through the ventilation path 31 exchanges heat with the heat exchanger 22.

[0090] The filter 24 is provided at the suction port 32 or near the suction port 32 in the ventilation path 31. The filter 24 is located upstream of the heat exchanger 22. The filter 24 covers the suction port 32 from the inside of the housing 21. The filter 24 filters the air sucked from the suction port 32 and captures dust in the air, for example.

[0091] The wind deflector 4 may also include a plurality of wind deflectors 25A and 25B. The plurality of wind deflectors 25A and 25B are components for adjusting the wind direction of the air-conditioned air in the up and down directions, and are also referred to as up and down louvers. The wind deflector 25A forms a flow path C1 of the air-conditioned air, and the wind deflector 25B forms a flow path C2 of the air-conditioned air. The plurality of wind deflectors 25A and 25B each have a shaft portion 41 and a plate portion 42.

[0092] The shaft portion 41 is formed in a generally cylindrical shape extending in the X direction. The shaft portion 41 is supported by the housing 21 in a manner that allows rotation around the rotation axis Ax1 extending in the X direction. In addition, each of the plurality of wind deflectors 25A and 25B has a separate rotation axis Ax1. The plate portion 42 protrudes from the shaft portion 41 in a direction generally orthogonal to the rotation axis Ax1. The plate portion 42 is formed in a generally rectangular plate shape extending in the X direction.

[0093] The wind deflector 25A is supported by the rotation axis Ax1, and is controlled by the wind deflector motor 85 through the drive circuit 82, so that it can move between the closed position Pc1 and the open position Po1. The wind deflector 25B is supported by the rotation axis Ax1, and is controlled by the wind deflector motor 85 through the drive circuit 82, so that it can move between the closed position Pc2 and the open position Po2.

[0094] like Figure 2 As shown, when the wind direction plate 25A is switched to the closed position Pc1, the vent C1 that will be the outlet of the flow path C1 is closed. When the wind direction plate 25B is switched to the closed position Pc1, the vent C2 that will be the outlet of the second flow path is closed. The vent C1 and the vent C2 form the air outlet 33 of the indoor unit 10.

[0095] like Figure 3 as well as Figure 4 As shown, the wind direction plate 25A opens the vent C1 when it is switched to the open position Po1, and the wind direction plate 25B opens the vent C2 when it is switched to the open position Po1.

[0096] The open position Po1 includes various positions where the wind direction plates 25A and 25B open a part of the air outlet 33. Figure 3 Thus, the open position Po1 includes a position where the wind deflectors 25A and 25B face substantially horizontally, a position where the wind deflectors 25A and 25B face downward, and a plurality of positions between these two positions. That is, the wind deflectors 25A and 25B can rotate between the position facing substantially horizontally and the position facing downward.

[0097] The wind direction plates 25A and 25B at the open position Po1 adjust the direction of the wind blown out from the air outlet 33 in the vertical direction (+Z direction, -Z direction) according to the direction of the wind direction plates 25A and 25B. Figure 3 Thus, the indoor unit 10 blows out wind in the substantially horizontal direction by the wind direction plates 25A and 25B being directed in the substantially horizontal direction. On the other hand, the indoor unit 10 blows out wind downward by the wind direction plates 25A and 25B being directed downward.

[0098] The wind deflector 5 is supported by a rotation axis Ax2 (not shown), and the wind deflector motor 86 is controlled by the drive circuit 82, so that the wind deflector 5 can move between an open position at the -X side end and an open position at the +X side end.

[0099] The wind deflector 5 may also include a plurality of wind deflectors 29-1 to 29-k, 29-(k+1) to 29-2k. The plurality of wind deflectors 29-1 to 29-k, 29-(k+1) to 29-2k are components for adjusting the wind direction of the conditioned air in the left and right directions (-X direction, +X direction), and are also referred to as left and right louvers. In addition, the wind deflectors 29-1 to 29-k on the -X side and the wind deflectors 29-(k+1) to 29-2k on the +X side can also be independently controlled in their directions by the control unit 3.

[0100] The wind deflectors 29-1 to 29-k on the -X side may also be connected to the common rotation axis Ax2, and the wind deflector motor 86 may be controlled by the drive circuit 82, so that they can move together between the open position at the -X side end and the open position at the +X side end. The wind deflectors 29-(k+1) to 29-2k on the +X side may also be connected to the common rotation axis Ax2, and the wind deflector motor 86 may be controlled by the drive circuit 82, so that they can move together between the open position at the -X side end and the open position at the +X side end.

[0101] Figure 1 The biosensor 2 shown can detect the position and speed of a biometric body CR in the room RM. The biometric body CR is, for example, a human being, in which case the biometric sensor 2 may be a human body sensor. The biometric sensor 2 is, for example, a radar, or a Doppler radar such as a millimeter wave radar or a microwave radar.

[0102] The biosensor 2 has a transmitting unit 2a, a receiving unit 2b, and a signal processing unit 2c. The biosensor 2 generates radio waves such as millimeter waves and microwaves through the signal processing unit 2c and transmits them from the transmitting unit 2a to the biological body CR, and receives the reflected waves through the receiving unit 2b and transmits them to the signal processing unit 2c. The signal processing unit 2c can also implement the signal processing function as a signal processing circuit in hardware.

[0103] The biosensor 2 is installed at any position of the indoor unit 10, but is preferably installed at a position where the position and speed of the biosensor CR in the room RM can be easily detected. Figure 2 to Figure 4 As shown by the middle dotted line, the biosensor 2 may be embedded in a position near the center in the X direction of the +Y side portion of the housing 21 .

[0104] like Figure 5 As shown, the biosensor 2 can detect the position of the living body CR based on the phase difference and direction of the transmission wave and the reception wave by the signal processing unit 2c. Figure 5 FIG. 2 is a diagram showing the operation of the biosensor 2 (eg, radar). Figure 5 In FIG. 1 , the position of the biological body CR to be detected is indicated by a dot.

[0105] The biosensor 2 detects the target space and the position of the living body CR in the target space under the control of the control unit 3. The biosensor 2 periodically or continuously transmits and receives electric waves with respect to the living body CR to detect the position of the living body CR, and periodically or continuously supplies the detection result to the control unit 3.

[0106] At this time, if the signal processing function in the signal processing unit 2c is implemented as a signal processing circuit by hardware, the signal processing can be performed at a higher speed than when the signal processing function is implemented by software. By performing the signal processing at a high speed in the signal processing circuit, the processing of detecting the position of the living body CR based on the phase difference between the transmission wave and the reception wave can be performed at a high speed. As a result, the current position of the living body CR can be detected in substantially real time, and the control of tracking the current position of the living body CR can be easily performed.

[0107] For example, the biosensor 2 detects an indoor RM having a length L1, a width W1, and an area L1×W1. Figure 6 As shown in (a) of FIG. 1 , the control unit 3 specifies the indoor room RM having a length L1 , a width W1 , and an area L1×W1 as the target space based on the detection result of the biosensor 2 , and allocates an identifier SP1 to the space. Figure 6 is a diagram showing information detected by the biosensor 2, Figure 6 (a) represents information related to the space detected by the biosensor 2, Figure 6 (b) shows information related to the biological body CR detected by the biological sensor 2.

[0108] The control unit 3 sets the coordinates in the target space SP1. The biosensor 2 may detect the target space in a manner that further includes the height of the space. In this case, the volume of the target space can also be detected. Figure 5 In the target space SP1, the determined target space is represented by a rectangle, and the horizontal coordinate and the vertical coordinate are represented. The biosensor 2 detects the position of the biological body CR in the target space SP1 under the control of the control unit 3. The biosensor 2 detects the distance, horizontal angle, and vertical angle of the two biological bodies CR.

[0109] like Figure 6 As shown in (b), the control unit 3 assigns the biometric identifiers ID1 and ID2 to the two biometric bodies CR, respectively, based on the detection results of the biometric sensor 2. The control unit 3 determines the distance D1, horizontal angle θ1, and vertical angle α1 of the biometric body CR of ID1, and determines the distance D2, horizontal angle θ2, and vertical angle α2 of the biometric body CR of ID2, based on the detection results of the biometric sensor 2.

[0110] The control unit 3 converts the distance, horizontal angle, and vertical angle of the two living bodies CR into coordinates (horizontal coordinates and vertical coordinates) in the object space. Figure 5As shown by dots in , the control unit 3 recognizes that two living bodies CR exist at the coordinates. The control unit 3 determines that the coordinates close in space with respect to the temporally continuous detection results correspond to the same identifier even if the two living bodies CR have moved.

[0111] When one biological body CR is detected by the biological sensor 2, the control unit 3 locks the detected biological body CR. When multiple biological bodies CR are detected by the biological sensor 2, the control unit 3 selects one biological body CR from the multiple biological bodies CR according to a predetermined condition and locks the selected biological body CR. The control unit 3 can continuously recognize the position of the locked biological body CR based on the continuous detection results of the biological sensor 2. Thus, the control unit 3 can track the locked biological body CR.

[0112] Furthermore, the biosensor 2 can detect the positions of multiple parts of the living body CR respectively. The control unit 3 may also assign a biometric identifier to each set of multiple detection positions close in space based on the detection results of the biosensor 2. Figure 5 In the case of the above, the control unit 3 determines the positional relationship between the plurality of detection positions in the set of the plurality of detection positions for the two biological bodies CR, respectively. Thus, the control unit 3 can grasp the postures (e.g., the posture of sitting on the floor, the posture of sitting on a chair, the posture of standing, the posture of lying, the posture of squatting, etc.) of the two biological bodies CR, respectively.

[0113] In addition, if Figure 5 As shown, the biosensor 2 can detect the velocity of the living body CR by the Doppler effect based on the frequency difference (or wavelength difference) between the transmission wave and the reception wave in the signal processing unit 2c.

[0114] exist Figure 5 In the case of , the biosensor 2 further detects the speed of each of the two biosensors CR. Figure 6 As shown in (b), the control unit 3 determines the speed v1 of the biological body CR of ID1 and the speed v2 of the biological body CR of ID2 based on the detection result of the biological sensor 2. Figure 5 In FIG. 1 , the speed of each living body CR determined by the control unit 3 is represented by the length of the line.

[0115] Figure 1 The receiving device 94 shown receives the instruction from the operation terminal 94a. The receiving device 94 supplies the received instruction to the control unit 3. The control unit 3 can also transmit the instruction to the control unit 103. For example, Figure 7 As shown, the operation terminal 94a may have a button for instructing use of the power-saving cooling mode or the power-saving heating mode. Figure 7It is a perspective view showing the external appearance structure of the operation terminal 94a, and illustrates the structure in the case where the operation terminal 94a is a remote controller.

[0116] The operation terminal 94a has a shape and size suitable for operation by the biological body CR, and has a roughly rectangular appearance. The operation terminal 94a has a plurality of buttons and a display unit 949 on its operation surface. The plurality of buttons include, for example, a biological sensor button 941, a cooling button 942, a heating button 943, an air cleaning button 944, a temperature setting button 945, a dehumidification button 946, a windless button 947, a stop button 948, a power-saving cooling button 9410, a power-saving heating button 9411, a power-saving setting button 9412, and a setting air volume button 9413. In the case where the biological sensor 2 is a radar, the biological sensor button 941 may also be a radar button. The display unit 949 may be a display or a display screen. The display includes a liquid crystal display or an organic EL display. The display screen is a 7-segment LED display screen.

[0117] When the biosensor button 941, the cooling button 942, the heating button 943, the air cleaning button 944, the dehumidification button 946, the windless button 947, the stop button 948, the power-saving cooling button 9410, and the power-saving heating button 9411 are pressed, the operation terminal 94a detects the pressing. The operation terminal 94a detects the pressing of the △ button or the ▽ button for the temperature setting button 945. The operation terminal 94a detects the pressing of the △ button or the ▽ button for the air volume setting button 9413. The operation terminal 94a detects the pressing of the △ button or the ▽ button for the power saving setting button 9412. When the operation terminal 94a detects the pressing, the information of the instruction corresponding to the pressed button is displayed on the display unit 949, and a signal (for example, an infrared signal or a wireless signal) indicating the instruction corresponding to the pressed button is sent from its end.

[0118] The operation terminal 94 a can also receive an instruction to turn on or off the power-saving cooling mode via the power-saving cooling button 9410 .

[0119] When the operation terminal 94a detects the pressing of a button indicating the start of the power-saving cooling mode (for example, the pressing of the power-saving cooling button 9410), the operation terminal 94a transmits the instruction to start the power-saving cooling mode to the indoor unit 10. When the receiving device 94 receives the instruction to start the power-saving cooling mode, it supplies the instruction to the control unit 3. The control unit 3 transmits the instruction to start the power-saving cooling mode to the control unit 103.

[0120] In addition, when receiving the instruction to turn on the power-saving cooling mode, the operation terminal 94a may display information related to the power-saving cooling mode (information related to the first mode) on the display unit 949. The information related to the power-saving cooling mode may be, for example, text information indicating the power-saving cooling mode such as "power-saving cooling", or a display object such as a graphic or a symbol indicating "power-saving cooling".

[0121] In addition, the purpose of the control unit 3 transmitting the instruction to turn on the power-saving cooling mode to the control unit 103 is to make the control unit 3 and the control unit 103 cooperate to control the operation of the power-saving cooling mode, but the control unit 3 may mainly perform air conditioning processing. In this case, the process of the control unit 3 transmitting the instruction to turn on the power-saving cooling mode to the control unit 103 may be omitted. The outdoor unit 100 may also be a structure in which the control unit 103 is omitted. Alternatively, the control unit 103 may mainly perform air conditioning processing. In this case, the outdoor unit 100 may also be a structure in which the control unit 3 is omitted. The receiving device 94 may also directly transmit the instruction to turn on the power-saving cooling mode to the control unit 103.

[0122] When the operation terminal 94a detects the pressing of a button indicating the closing of the power-saving cooling mode (for example, the pressing of the stop button 948 or the pressing of the power-saving cooling button 9410 again), the instruction to close the power-saving cooling mode is sent to the indoor unit 10. When the receiving device 94 receives the instruction to close the power-saving cooling mode, it supplies the instruction to the control unit 3. The control unit 3 transmits the instruction to close the power-saving cooling mode to the control unit 103.

[0123] The operation terminal 94 a may also receive an instruction to turn on or off the power-saving heating mode via the power-saving heating button 9411 .

[0124] When the operation terminal 94a detects the pressing of a button indicating the activation of the power-saving heating mode (for example, the pressing of the power-saving heating button 9411), the operation terminal 94a transmits the activation instruction of the power-saving heating mode to the indoor unit 10. When the receiving device 94 receives the activation instruction of the power-saving heating mode, it supplies the instruction to the control unit 3. The control unit 3 transmits the activation instruction of the power-saving heating mode to the control unit 103.

[0125] In addition, when receiving the instruction to turn on the power-saving heating mode, the operation terminal 94a may display information related to the power-saving heating mode (information related to the fourth mode) on the display unit 949. The information related to the power-saving heating mode may be, for example, text information indicating the power-saving heating mode such as "power-saving heating", or a display object such as a graphic or a symbol indicating "power-saving heating".

[0126] In addition, the purpose of the control unit 3 transmitting the instruction to turn on the power-saving heating mode to the control unit 103 is to make the control unit 3 cooperate with the control unit 103 to control the operation of the power-saving heating mode, but the control unit 3 may mainly perform air conditioning processing. In this case, the process of the control unit 3 transmitting the instruction to turn on the power-saving heating mode to the control unit 103 may be omitted. The outdoor unit 100 may also be a structure in which the control unit 103 is omitted. Alternatively, the control unit 103 may mainly perform air conditioning processing. In this case, the outdoor unit 100 may also be a structure in which the control unit 3 is omitted. The receiving device 94 may also directly transmit the instruction to turn on the power-saving heating mode to the control unit 103.

[0127] When the operation terminal 94a detects the pressing of a button indicating the closing of the power-saving heating mode (for example, the pressing of the stop button 948 or the pressing of the power-saving heating button 9411 again), the instruction to close the power-saving heating mode is sent to the indoor unit 10. When the receiving device 94 receives the instruction to close the power-saving heating mode, it supplies the instruction to the control unit 3. The control unit 3 transmits the instruction to close the power-saving heating mode to the control unit 103.

[0128] The operation terminal 94 a may also receive an instruction to set the temperature via the temperature setting button 945 .

[0129] When the operation terminal 94a detects that the △ button of the temperature setting button 945 is pressed, the set temperature value is increased from the current value, the increased set temperature value is displayed on the display unit 949, and the instruction of the increased set temperature is sent to the indoor unit 10. When the operation terminal 94a detects that the ▽ button of the temperature setting button 945 is pressed, the set temperature value is reduced from the current value, the reduced set temperature value is displayed on the display unit 949, and the instruction of the reduced set temperature is sent to the indoor unit 10. When the receiving device 94 receives the instruction of the increased or reduced set temperature, it supplies the instruction to the control unit 3. The control unit 3 may also transmit the instruction of the set temperature to the control unit 103.

[0130] The operation terminal 94 a may also receive an instruction to set the air volume via the air volume setting button 9413 .

[0131] When the operation terminal 94a detects that the △ button of the air volume setting button 9413 is pressed, the size of the set air volume is increased from the current size, the value of the set air volume after the change is displayed on the display unit 949, and the instruction of the changed set air volume is sent to the indoor unit 10. When the operation terminal 94a detects that the ▽ button of the air volume setting button 9413 is pressed, the size of the set air volume is decreased from the current size, the value of the set air volume after the change is displayed on the display unit 949, and the instruction of the changed set air volume is sent to the indoor unit 10. When receiving the instruction to set the air volume, the receiving device 94 supplies the instruction to the control unit 3. The control unit 3 transmits the instruction to set the air volume to the control unit 103.

[0132] The control unit 3 generally controls the indoor unit 10. Figure 8 As shown, the control unit 3 has a tracking control mode, a power-saving cooling mode, a power-saving heating mode, and a normal control mode as control modes. Figure 8 : is a state transition diagram showing the control mode of the air-conditioning device 1 .

[0133] When the operation terminal 94a detects the pressing of a button indicating the start of the power-saving cooling mode (for example, the pressing of the power-saving cooling button 9410) during the stop of the air-conditioning device 1, the command to start the power-saving cooling mode is sent from the operation terminal 94a to the indoor unit 10. When the control unit 3 receives the command to start the power-saving cooling mode, it changes the control mode from "stop" to the power-saving cooling mode according to the command to start the power-saving cooling mode.

[0134] When the operation terminal 94a detects that a normal operation button (e.g., the cooling button 942, the heating button 943, the air cleaning button 944, and the dehumidification button 946) is pressed while the air conditioning device 1 is stopped, the normal operation instruction is sent from the operation terminal 94a to the indoor unit 10. When receiving the normal operation instruction, the control unit 3 changes the control mode from the "stop" to the normal control mode according to the normal operation instruction.

[0135] In the normal control mode, when the operation terminal 94a receives the pressing of a button indicating the activation of the power-saving cooling mode (for example, the pressing of the power-saving cooling button 9410), the instruction for activating the power-saving cooling mode is sent from the operation terminal 94a to the indoor unit 10. When the control unit 3 receives the instruction for activating the power-saving cooling mode, it changes the control mode from the normal control mode to the power-saving cooling mode according to the instruction for activating the power-saving cooling mode.

[0136] In the power-saving cooling mode, when the operation terminal 94a detects the pressing of the button indicating the closing of the power-saving cooling mode and the opening of the normal operation (for example, the power-saving cooling button 9410 is pressed again), the instruction to close the power-saving cooling mode and to open the normal operation is sent from the operation terminal 94a to the indoor unit 10. When the control unit 3 receives the instruction to close the power-saving cooling mode and to open the normal operation, it changes the control mode from the power-saving cooling mode to the normal control mode according to the instruction to close the power-saving cooling mode and to open the normal operation.

[0137] In addition, the transition from the power-saving cooling mode to the normal control mode can be triggered by the passage of a specified time (for example, 2 hours). For example, the control unit 3 may also have a timer (not shown) set with a specified time. The specified time can be arbitrarily set to the timer via the operation terminal 94a. When the control mode becomes the power-saving cooling mode, the control unit 3 starts the timer. When the time of the timer reaches the specified time, the control unit 3 automatically ends the power-saving cooling mode and changes the control mode from the power-saving cooling mode to the normal control mode.

[0138] In the power-saving cooling mode, when the operation terminal 94a detects the pressing of a button for closing the power-saving cooling mode and stopping the operation (for example, the pressing of the stop button 948), the instruction for closing the power-saving cooling mode and stopping the operation is sent from the operation terminal 94a to the indoor unit 10. The control unit 3 changes the control mode from the power-saving cooling mode to "stop" according to the instruction for closing the power-saving cooling mode and stopping the operation.

[0139] In the normal control mode, when the operation terminal 94a detects the pressing of a button indicating the activation of the power-saving heating mode (for example, the pressing of the power-saving heating button 9411), the instruction to activate the power-saving heating mode is sent from the operation terminal 94a to the indoor unit 10. When the control unit 3 receives the instruction to activate the power-saving heating mode, it changes the control mode from the normal control mode to the power-saving heating mode according to the instruction to activate the power-saving heating mode.

[0140] In the power-saving heating mode, when the operation terminal 94a receives the pressing of the button indicating the closing of the power-saving heating mode and the opening of the normal operation (for example, the power-saving heating button 9411 is pressed again), the instruction of closing the power-saving heating mode and opening the normal operation is sent from the operation terminal 94a to the indoor unit 10. When the control unit 3 receives the instruction of closing the power-saving heating mode and opening the normal operation, it changes the control mode from the power-saving heating mode to the normal control mode according to the instruction of closing the power-saving heating mode and opening the normal operation.

[0141] In addition, the transition from the power-saving heating mode to the normal control mode can also be performed by taking the passage of a specified time (for example, 2 hours) as an opportunity. For example, the control unit 3 may also have a timer (not shown) set with a specified time. The specified time can be arbitrarily set to the timer via the operation terminal 94a. When the control mode becomes the power-saving heating mode, the control unit 3 starts the timer. When the time of the timer reaches the specified time, the control unit 3 automatically ends the power-saving heating mode and changes the control mode from the power-saving heating mode to the normal control mode.

[0142] In the power-saving heating mode, when the operation terminal 94a detects the pressing of the button for closing the power-saving cooling mode and stopping the operation (for example, the pressing of the stop button 948), the instruction for closing the power-saving cooling mode and stopping the operation is sent from the operation terminal 94a to the indoor unit 10. The control unit 3 changes the control mode from the power-saving heating mode to "stop" according to the instruction for closing the power-saving cooling mode and stopping the operation.

[0143] In the normal control mode, when the operation terminal 94a detects the pressing of a button for stopping operation (for example, the pressing of the stop button 948), the operation stop instruction is sent from the operation terminal 94a to the indoor unit 10. The control unit 3 changes the control mode from the normal control mode to "stop" according to the operation stop instruction.

[0144] In the power-saving cooling mode, the control unit 3 periodically or continuously receives the detection result from the biosensor 2. In the power-saving cooling mode, the control unit 3 tracks the position of the biosensor CR in the room RM while controlling the wind direction plates 4 and 5 to perform a predetermined operation. At the same time, the control unit 3 and the control unit 103 control the refrigerant circuit so as to perform a cooling operation at a target temperature higher than the set temperature. The control unit 103 controls the compressor 125 to operate at a second speed lower than the first speed corresponding to the set temperature.

[0145] The predetermined action is the action of the wind direction plates 4 and 5 in the direction of blowing toward the position of the biological body CR. The control of the control unit 3 to make the wind direction plates 4 and 5 perform the predetermined action is also called blowing control. The control of the wind direction plates 4 and 5 to perform the predetermined action by the control unit 3 in the power-saving cooling mode or the tracking control mode can also be set in advance in the control unit 3 through the operation terminal 94a.

[0146] The air blowing control in the power saving cooling mode or the air blowing control in the tracking control mode can also be performed as follows. Fig. 9 as well as Fig.10 Proceed as shown. Fig. 9 is a top view showing the air blowing control of the indoor unit of the air conditioner. Fig.10 It is a side view showing the air blowing control of the indoor unit of the air conditioning apparatus. Fig. 9(a)~ Fig. 9 (d) illustrates the time transition of the air blowing control in the XY plan view. Fig.10 (a)~ Fig.10 (d) illustrates the time lapse of the air blowing control in the YZ side view.

[0147] For example, Fig. 9 (a) Fig.10 As shown in (a), the operation terminal 94a is operated by the organism CR, and the power-saving refrigeration button 9410 is pressed. Correspondingly, the instruction to turn on the power-saving refrigeration mode and the instruction to set the temperature are sent from the operation terminal 94a to the indoor unit 10, and are received by the receiving device 94 of the indoor unit 10. The control unit 3 of the indoor unit 10 sets the control mode to the power-saving refrigeration mode and the operation mode to the refrigeration operation mode. The control unit 3 calculates a target temperature lower than the set temperature. The air-conditioning device 1 switches the four-way valve 124 to the refrigeration side, starts the fans 23 and 123 to rotate, and starts controlling the compressor 125 at a rotation speed corresponding to the target temperature. As a result, the air-conditioning device 1 starts the refrigeration operation so that the temperature of the indoor RM detected by the room temperature sensor 7 is close to the target temperature. The air-conditioning device 1 can also perform the refrigeration operation with a set air volume.

[0148] like Fig. 9 (b) Fig.10 As shown in (b), the control unit 3 of the indoor unit 10 detects the position of the biological body CR of the indoor RM through the biological body sensor 2 when the control mode becomes the power-saving cooling mode. The control unit 3 recognizes that a biological body CR of the indoor RM is detected by the biological body sensor 2, and locks the biological body CR as a tracking target.

[0149] like Fig. 9 As shown in (b), the biosensor 2 detects the presence of a biomolecule CR at a plane position P12b near the center in the Y direction and on the -X side of the room RM. Fig.10 As shown in (b) of FIG. 1 , the biosensor 2 detects that the biometric subject CR is in a sitting position on the floor. The biosensor 2 supplies the detection result to the control unit 3. Fig. 9 As shown in (b), the control unit 3 controls based on the detection result of the biosensor 2 so that the wind deflector 5 is directed toward the plane position P12b in the XY plan view and blows out conditioned air as shown by the dot-dash arrow.

[0150] like Fig.10As shown in (b), the control unit 3 controls according to the detection result of the biosensor 2 so that the wind deflector 4 is directed to blow toward the height position P13b of the biosensor CR corresponding to the biosensor CR (for example, the facial position of the biosensor CR) in the YZ side view, and blows out the conditioned air as indicated by the single-dot-dash arrow. In addition, the height position of the conditioned air can be set corresponding to any position of the biosensor CR such as the trunk, for example. The single-dot-dash arrow indicates the flow of the conditioned air that becomes the mainstream.

[0151] Thus, the wind direction of the indoor unit 10 can be controlled so that the wind blown from the indoor unit 10 blows on the living body CR. By blowing the wind on the living body CR, the sensible temperature of the living body CR can be effectively lowered. As a result, in the air blowing control of the power-saving cooling mode, the sensible temperature of the living body CR can be brought close to the set temperature while performing cooling operation at the target temperature.

[0152] like Fig. 9 (c) Fig.10 As shown in (c), then Fig. 9 (b) Fig.10 In (b), the control unit 3 of the indoor unit 10 detects the position of the biological body CR in the room RM through the biological sensor 2.

[0153] like Fig. 9 As shown in (c) of FIG. 1 , the biosensor 2 detects the presence of a biomolecule CR at a plane position P12c in the center of the room RM in the X direction and near the center in the Y direction. Fig.10 As shown in (c) of FIG. 1 , the biosensor 2 detects that the biometric subject CR is in a sitting position on a chair. The biosensor 2 supplies the detection result to the control unit 3. Fig. 9 As shown in (c), the control unit 3 controls based on the detection result of the biosensor 2 so that the wind deflector 5 is directed toward the plane position P12c in the XY plan view and blows out conditioned air as shown by the dot-dash arrow.

[0154] like Fig.10 As shown in (c), the control unit 3 is controlled based on the detection result of the biological sensor 2 so that the wind deflector 4 is directed to blow in the direction of P13c of the height position of the biological body CR corresponding to the posture of the biological body CR (for example, the facial position of the biological body CR) in the YZ side view, and blows out conditioned air as indicated by the single-dash arrow.

[0155] Thus, the wind direction can be controlled so that the wind blown from the indoor unit 10 blows onto the living body CR while tracking the locked living body CR. By blowing the wind onto the living body CR, the perceived temperature of the living body CR can be effectively lowered. As a result, in the air blowing control in the power-saving cooling mode, the perceived temperature of the living body CR can be brought close to the set temperature while performing cooling operation at the target temperature.

[0156] like Fig. 9 (d) Fig.10 As shown in (d), then Fig. 9 (c) Fig.10 In (c), the control unit 3 of the indoor unit 10 detects the position of the biological body CR in the room RM through the biological sensor 2.

[0157] like Fig. 9 As shown in (d) of FIG. 1 , the biosensor 2 detects the presence of a biomolecule CR at a plane position P12d on the +X side and the +Y side of the room RM. Fig.10 As shown in (d) of FIG. 1 , the biosensor 2 detects that the biological body CR is in a standing posture. The biosensor 2 supplies the detection result to the control unit 3. Fig. 9 As shown in (d), the control unit 3 controls based on the detection result of the biosensor 2 so that the wind deflector 5 is directed to blow toward the plane position P12d in the XY plan view and blows out conditioned air as shown by the dot-dash arrow.

[0158] like Fig.10 As shown in (d), the control unit 3 is controlled based on the detection result of the biological sensor 2 so that the wind deflector 4 is directed to blow in the direction of the height position P13d of the biological body CR corresponding to the posture of the biological body CR (for example, the facial position of the biological body CR) in the YZ side view, and blows out conditioned air as indicated by the single-dash arrow.

[0159] Thus, the wind direction can be controlled so that the wind blown from the indoor unit 10 blows onto the living body CR while tracking the locked living body CR. By blowing the wind onto the living body CR, the perceived temperature of the living body CR can be effectively lowered. As a result, in the air blowing control in the power-saving cooling mode, the perceived temperature of the living body CR can be brought close to the set temperature while performing cooling operation at the target temperature.

[0160] In the power-saving cooling mode, a correction value for making the target temperature higher by a certain number of degrees than the set temperature may be fixedly set in the control unit 3 and the control unit 103. For example, the correction value may be fixed to +1°C.

[0161] Alternatively, in the power-saving cooling mode, the correction value may be arbitrarily set via the operation terminal 94a. For example, the correction value may be set within a range of +1°C to +3°C.

[0162] The operation terminal 94 a can also accept setting of a correction value in the power-saving cooling mode via the power-saving setting button 9412 .

[0163] When the operation terminal 94a detects that the △ button of the power saving setting button 9412 is pressed, the correction value is increased from the current value, the increased correction value is displayed on the display unit 949, and the instruction of the increased correction value is sent to the indoor unit 10. When the operation terminal 94a detects that the ▽ button of the temperature setting button 945 is pressed, the correction value is reduced from the current value, the reduced correction value is displayed on the display unit 949, and the instruction of the reduced correction value is sent to the indoor unit 10. When the receiving device 94 receives the instruction of the increased or reduced correction value, it supplies the instruction to the control unit 3. The control unit 3 corrects the set temperature with the correction value to obtain the target temperature and transmits it to the control unit 103. The control unit 3 and the control unit 103 control the cooling operation at the target temperature.

[0164] Thus, the power saving level in the power saving cooling mode can be adjusted according to the setting of the correction value. The larger the correction value is set, the larger the power saving level in the power saving cooling mode can be adjusted.

[0165] The control unit 3 periodically or continuously receives the detection result from the biosensor 2 in the power-saving heating mode. The control unit 3 controls the wind direction plates 4 and 5 to perform a predetermined operation while tracking the position of the biosensor CR of the indoor RM in the power-saving heating mode. At the same time, the control unit 3 and the control unit 103 control the refrigerant circuit so as to perform a heating operation at a target temperature lower than the set temperature. The control unit 103 controls the compressor 125 to operate at a fourth speed lower than the third speed corresponding to the set temperature.

[0166] The prescribed action is the action of the wind direction plates 4 and 5 in the direction of blowing toward the position of the biological body CR. The control of the control unit 3 to make the wind direction plates 4 and 5 perform the prescribed action is also called blowing control. The control of the wind direction plates 4 and 5 to perform the prescribed action by the control unit 3 in the power saving heating mode or the tracking control mode can also be set in the control unit 3 in advance through the operation terminal 94a.

[0167] The air blowing control in the power saving heating mode or the air blowing control in the tracking control mode can also be performed as follows. Fig. 9 as well as Fig.11 Proceed as shown. Fig.11 It is a side view showing the air blowing control of the indoor unit of the air conditioning apparatus. Fig.11 (a)~ Fig.11(d) illustrates the time lapse of the air blowing control in the YZ side view.

[0168] For example, Fig. 9 (a) Fig.11 As shown in (a), the operation terminal 94a is operated by the organism CR, and the power-saving heating button 9411 is pressed. Correspondingly, the instruction to turn on the power-saving heating mode and the instruction to set the temperature are sent from the operation terminal 94a to the indoor unit 10, and are received by the receiving device 94 of the indoor unit 10. The control unit 3 of the indoor unit 10 sets the control mode to the power-saving heating mode and the operation mode to the heating operation mode. The control unit 3 calculates a target temperature higher than the set temperature. The air-conditioning device 1 switches the four-way valve 124 to the heating side, causes the fans 23 and 123 to start rotating, and starts controlling the compressor 125 at a speed corresponding to the target temperature. As a result, the air-conditioning device 1 starts the heating operation so that the temperature of the indoor RM detected by the room temperature sensor 7 is close to the target temperature. The air-conditioning device 1 can also perform the heating operation with a set air volume.

[0169] like Fig. 9 (b) Fig.11 As shown in (b), the control unit 3 of the indoor unit 10 detects the position of the biological body CR of the indoor RM through the biological body sensor 2 when the control mode becomes the power-saving heating mode. The control unit 3 recognizes that a biological body CR of the indoor RM is detected by the biological body sensor 2, and locks the biological body CR as a tracking target.

[0170] like Fig. 9 As shown in (b), the biosensor 2 detects the presence of a biomolecule CR at a plane position P12b near the center in the Y direction and on the -X side of the room RM. Fig.11 As shown in (b) of FIG. 1 , the biosensor 2 detects that the biometric subject CR is in a sitting position on the floor. The biosensor 2 supplies the detection result to the control unit 3. Fig. 9 As shown in (b), the control unit 3 controls based on the detection result of the biosensor 2 so that the wind deflector 5 is directed toward the plane position P12b in the XY plan view and blows out conditioned air as shown by the dot-dash arrow.

[0171] like Fig.11 As shown in (b), the control unit 3 controls based on the detection result of the biosensor 2 so that the wind direction plate 4 is directed to blow toward the height position P14b of the feet of the living body CR corresponding to the posture of the living body CR in the YZ side view, and blows out the conditioned air as shown by the single-dot chain line arrow. The single-dot chain line arrow represents the flow of the conditioned air that becomes the mainstream.

[0172] Thus, the wind direction can be controlled so that the wind blown from the indoor unit 10 reaches the feet of the living body CR. By making the wind reach the feet of the living body CR, the living body CR can be heated from the feet, and the sensible temperature of the living body CR can be effectively increased. As a result, in the air blowing control in the power-saving heating mode, the sensible temperature of the living body CR can be brought close to the set temperature while performing the heating operation at the target temperature.

[0173] like Fig. 9 (c) Fig.11 As shown in (c), then Fig. 9 (b) Fig.11 In (b), the control unit 3 of the indoor unit 10 detects the position of the biological body CR in the room RM through the biological sensor 2.

[0174] like Fig. 9 As shown in (c) of FIG. 1 , the biosensor 2 detects the presence of a biomolecule CR at a plane position P12c in the center of the room RM in the X direction and near the center of the room RM in the Y direction. Fig.11 As shown in (c) of FIG. 1 , the biosensor 2 detects that the biometric subject CR is in a sitting position on a chair. The biosensor 2 supplies the detection result to the control unit 3. Fig. 9 As shown in (c), the control unit 3 controls based on the detection result of the biosensor 2 so that the wind deflector 5 is directed toward the plane position P12c in the XY plan view and blows out conditioned air as shown by the dot-dash arrow.

[0175] like Fig.11 As shown in (c), the control unit 3 is controlled according to the detection result of the biological sensor 2 so that the wind deflector 4 is directed to blow in the direction of the height position P14c of the feet of the biological body CR corresponding to the posture of the biological body CR in the YZ side view, and blows out conditioned air as indicated by the single-dot dashed arrow.

[0176] Thus, the wind direction can be controlled so that the wind blown from the indoor unit 10 reaches the feet of the living body CR while tracking the locked living body CR. Since the wind reaches the feet of the living body CR, the living body CR can be heated from the feet, and the sensible temperature of the living body CR can be effectively increased. As a result, in the air blowing control in the power-saving heating mode, the sensible temperature of the living body CR can be brought close to the set temperature while performing the heating operation at the target temperature.

[0177] like Fig. 9 (d) Fig.11 As shown in (d), then Fig. 9 (c) Fig.11 In (c), the control unit 3 of the indoor unit 10 detects the position of the biological body CR in the room RM through the biological sensor 2.

[0178] like Fig. 9 As shown in (d) of FIG. 1 , the biosensor 2 detects the presence of a biomolecule CR at a plane position P12d on the +X side and the +Y side of the room RM. Fig.11 As shown in (d) of FIG. 1 , the biosensor 2 detects that the biological body CR is in a standing posture. The biosensor 2 supplies the detection result to the control unit 3. Fig. 9 As shown in (d), the control unit 3 controls based on the detection result of the biosensor 2 so that the wind deflector 5 is directed to blow toward the plane position P12d in the XY plan view and blows out conditioned air as shown by the dot-dash arrow.

[0179] like Fig.11 As shown in (d), the control unit 3 is controlled according to the detection result of the biological sensor 2 so that the wind deflector 4 is directed to blow in the direction of the height position P14d of the feet of the biological body CR corresponding to the posture of the biological body CR in the YZ side view, and blows out conditioned air as indicated by the single-dot dashed arrow.

[0180] Thus, the direction of the wind blown from the indoor unit 10 can be controlled so as to reach the feet of the living body CR while tracking the locked living body CR. Since the wind reaches the feet of the living body CR, the living body CR can be heated from the feet, and the sensible temperature of the living body CR can be effectively increased. As a result, in the air blowing control in the power-saving heating mode, the sensible temperature of the living body CR can be brought close to the set temperature while performing the heating operation at the target temperature.

[0181] In the energy-saving heating mode, a correction value for making the target temperature higher than the set temperature by a certain number of degrees may be fixedly set in the control unit 3 and the control unit 103. For example, the correction value may be fixed to -1°C.

[0182] Alternatively, in the energy-saving heating mode, the correction value can be arbitrarily set via the operation terminal 94a. For example, the correction value can be set within the range of -1°C to -3°C.

[0183] The operation terminal 94 a can also accept setting of a correction value in the power-saving heating mode via the power-saving setting button 9412 .

[0184] When the operation terminal 94a detects that the △ button of the power saving setting button 9412 is pressed, the correction value is increased from the current value, the increased correction value is displayed on the display unit 949, and the instruction of the increased correction value is sent to the indoor unit 10. When the operation terminal 94a detects that the ▽ button of the temperature setting button 945 is pressed, the correction value is reduced from the current value, the reduced correction value is displayed on the display unit 949, and the instruction of the reduced correction value is sent to the indoor unit 10. When receiving the instruction of the increased or reduced correction value, the receiving device 94 supplies the instruction to the control unit 3. The control unit 3 transmits the instruction of setting the temperature to the control unit 103.

[0185] Thus, the power saving level in the power saving heating mode can be adjusted according to the setting of the correction value. The smaller the correction value is set (the larger the absolute value is), the greater the power saving level in the power saving heating mode can be adjusted.

[0186] As described above, in the embodiment, for example, the biosensor 2 detects the position of the biomass CR in the room RM. In the power-saving cooling mode, the air conditioner 1 tracks the detected position of the biomass CR and directs the wind direction plates 4 and 5 toward the position of the biomass CR, and performs cooling operation at a target temperature higher than the set temperature. Thus, when the biomass CR moves in the room RM, the conditioned air can be blown onto the biomass CR to effectively lower the perceived temperature of the biomass CR, and the cooling operation can be performed at a load lower than the load corresponding to the set temperature. As a result, the comfort of the biomass CR in the room RM can be dynamically improved, and the power consumption of the air conditioner 1 can be reduced.

[0187] In addition, in the embodiment, the case where the indoor unit 10 has one biosensor 2 is illustrated, but the indoor unit 10 may also have a plurality of biosensors. In this case, the indoor unit 10 detects the position of the biomass CR through the plurality of biosensors, so the accuracy of position detection can be easily improved. In addition, in the embodiment, the power-saving cooling mode is illustrated, but the power-saving dehumidification mode (first mode) that performs the same control as the power-saving cooling mode may also be provided. That is, the following mode may also be provided: the wind direction plate is directed to the position where the wind blows toward the biomass CR, and the dehumidification operation is performed at a target temperature higher than the set temperature.

[0188] The air conditioner 1 may also perform heat-off control and set the operation mode to the air supply operation mode while maintaining the control mode to the power-saving cooling mode, based on the fact that the temperature of the room RM detected by the room temperature sensor 7 converges within a prescribed temperature range including the target temperature. The prescribed temperature range is a temperature range considered to be close to the target temperature, for example, a temperature range of -0.5°C or more and +0.5°C or less of the target temperature. In the heat-off control, the compressor 125 stops, and the circulation of the refrigerant in the refrigerant circuit stops.

[0189] For example, when the temperature of the room RM converges within a predetermined temperature range, the wind direction can be controlled so that the wind blown from the indoor unit 10 blows onto the living body CR while tracking the locked living body CR. By blowing the wind onto the living body CR, the perceived temperature of the living body CR can be effectively reduced. As a result, the perceived temperature of the living body CR can be brought close to the set temperature while performing the air supply operation within the predetermined temperature range. That is, the operating load of the air conditioner 1 can be further reduced, and the power consumption of the air conditioner 1 can be further reduced.

[0190] The air-conditioning apparatus 1 may release the thermo-off control and return the operation mode to the cooling operation mode while maintaining the control mode in the power-saving cooling mode when the temperature of the room RM deviates from a predetermined temperature range.

[0191] (First Modification of Implementation)

[0192] The target temperature in the power-saving cooling mode may be changed according to the difference (temperature difference) between the temperature of the room RM detected by the room temperature sensor 7 and the set temperature instructed by the operation terminal 94a.

[0193] In the power-saving cooling mode, the control unit 3 receives the detection result indicating the indoor temperature from the room temperature sensor 7 and receives the instruction of setting the temperature from the operation terminal 94a. The control unit 3 obtains the difference between the indoor temperature and the set temperature and obtains the temperature difference. The control unit 3 obtains the correction value based on the temperature difference.

[0194] At this time, the control unit 3 may also be set as follows Fig.12 Correction information for power saving cooling mode as shown. Fig.12 It is a diagram showing correction information for the power-saving cooling mode according to the first modified example of the embodiment.

[0195] In the correction information for the power-saving cooling mode, the temperature difference classification and the correction value are associated with each other for a plurality of temperature difference classifications. Fig.12 In the case of , it is decided to gradually reduce the correction value in accordance with the decrease in the temperature difference.

[0196] By referring to the correction information, the control unit 3 can obtain a correction value corresponding to the difference between the indoor temperature and the set temperature (temperature difference) in the power-saving refrigeration mode. The control unit 3 is such that when receiving the set temperature indicated by the operation terminal 94a, it can correct the set temperature with the correction value to obtain the target temperature.

[0197] In Fig.12 the case where, if the temperature difference is D1 or more, the correction value is obtained as +3°C according to the correction information. If the temperature difference is D2 (<D1) or more and less than D1, the correction value is obtained as +2°C according to the correction information. If the temperature difference is D3 (<D2) or more and less than D2, the correction value is obtained as +1°C according to the correction information. If the temperature difference is 0 or more and less than D3, the correction value is obtained as +0.5°C according to the correction information.

[0198] For example, let D1 = 9°C, D2 = 5°C, and D3 = 3°C. In this case, if the indoor temperature = 36°C and the set temperature = 26°C, then the temperature difference = 10°C. Since the temperature difference is D1 or more, the correction value is obtained as +3°C according to Fig.12 the correction information shown. The control unit 3 corrects the set temperature = 26°C with the correction value = +3°C and obtains the target temperature = 26°C + 3°C = 29°C.

[0199] Or, if the indoor temperature = 32°C and the set temperature = 26°C, then the temperature difference = 6°C. Since the temperature difference is D2 or more and less than D1, the correction value is obtained as +2°C according to Fig.12 the correction information shown. The control unit 3 corrects the set temperature = 26°C with the correction value = +2°C and obtains the target temperature = 26°C + 2°C = 28°C.

[0200] Or, if the indoor temperature = 30°C and the set temperature = 26°C, then the temperature difference = 4°C. Since the temperature difference is D3 or more and less than D2, the correction value is obtained as +1°C according to Fig.12 the correction information shown. The control unit 3 corrects the set temperature = 26°C with the correction value = +1°C and obtains the target temperature = 26°C + 1°C = 27°C.

[0201] Or, if the indoor temperature = 28°C and the set temperature = 26°C, then the temperature difference = 2°C. Since the temperature difference is 0 or more and less than D3, the correction value is obtained as +0.5°C according to Fig.12 the correction information shown. The control unit 3 corrects the set temperature = 26°C with the correction value = +0.5°C and obtains the target temperature = 26°C + 0.5°C = 26.5°C.

[0202] Thus, in the first modification of the embodiment, the air conditioner 1 changes the target temperature according to the difference (temperature difference) between the temperature of the indoor RM and the set temperature in the power-saving cooling mode. For example, in the power-saving cooling mode, the air conditioner 1 gradually reduces the correction value in response to a decrease in the temperature difference, and corrects the set temperature with this correction value to obtain the target temperature. As a result, the target temperature can gradually approach the set temperature in response to a decrease in the air-conditioning load. As a result, it is possible to reduce the power consumption of the air conditioner 1 while gradually improving the comfort of the living body CR.

[0203] (Second modification of the embodiment)

[0204] It is also possible to change the target temperature in the power-saving heating mode according to the difference (temperature difference) between the temperature of the indoor RM (room temperature) detected by the room temperature sensor 7 and the set temperature indicated by the operation terminal 94a.

[0205] In the power-saving heating mode, the control unit 3 receives the detection result indicating the room temperature from the room temperature sensor 7 and receives the command of the set temperature from the operation terminal 94a. The control unit 3 obtains the difference between the room temperature and the set temperature and calculates the temperature difference. The control unit 3 calculates a correction value based on the temperature difference.

[0206] At this time, correction information for the power-saving heating mode as shown Fig.13 may also be set in the control unit 3. Fig.13 FIG. is a diagram showing correction information for the power-saving heating mode of the second modification of the embodiment.

[0207] In the correction information for the power-saving heating mode, the temperature difference range is associated with the correction value for a plurality of temperature difference ranges. In Fig.13 this case, it is determined that the correction value gradually increases (the absolute value decreases) in response to a decrease in the temperature difference.

[0208] By referring to the correction information, the control unit 3 can calculate the correction value corresponding to the difference (temperature difference) between the room temperature and the set temperature in the power-saving heating mode. When the control unit 3 receives the set temperature indicated by the operation terminal 94a, the control unit 3 corrects the set temperature with the correction value to obtain the target temperature.

[0209] In Fig.13 this case, if the temperature difference is D11 or more, the correction value calculated according to the correction information is -3°C. If the temperature difference is D12 (<D11) or more and less than D11, the correction value calculated according to the correction information is -2°C. If the temperature difference is D13 (<D12) or more and less than D12, the correction value calculated according to the correction information is -1°C. If the temperature difference is 0 or more and less than D13, the correction value calculated according to the correction information is -0.5°C.

[0210] For example, D11 = 9°C, D12 = 5°C, and D13 = 3°C. In this case, if the room temperature = 36°C and the set temperature = 26°C, the temperature difference = 10°C. Since the temperature difference is greater than D11, Fig.13 The correction information shown obtains a correction value of -3°C. The control unit 3 corrects the set temperature = 26°C with the correction value = -3°C, and obtains a target temperature = 26°C - 3°C = 23°C.

[0211] Alternatively, if the room temperature = 32°C and the set temperature = 26°C, the temperature difference = 6°C. Since the temperature difference is greater than D12 and less than D11, according to Fig.13 The correction information shown obtains a correction value of -2°C. The control unit 3 corrects the set temperature = 26°C with the correction value = -2°C, and obtains a target temperature = 26°C - 2°C = 24°C.

[0212] Alternatively, if the room temperature = 30°C and the set temperature = 26°C, the temperature difference = 4°C. Since the temperature difference is greater than D13 and less than D12, according to Fig.13 The correction information shown obtains a correction value of -1°C. The control unit 3 corrects the set temperature = 26°C with the correction value = -1°C, and obtains a target temperature = 26°C - 1°C = 25°C.

[0213] Alternatively, if the room temperature = 28°C and the set temperature = 26°C, the temperature difference = 2°C. Since the temperature difference is greater than 0 and less than D13, Fig.13 The correction information shown obtains a correction value of -0.5° C. The control unit 3 corrects the set temperature = 26° C. with the correction value = -0.5° C., and obtains a target temperature = 26° C. - 0.5° C. = 25.5° C.

[0214] Thus, in the second variant of the embodiment, the air conditioner 1 changes the target temperature according to the difference (temperature difference) between the temperature of the indoor RM and the set temperature in the power-saving heating mode. For example, in the power-saving heating mode, the air conditioner 1 makes the correction value gradually smaller in accordance with the decrease in the temperature difference, and corrects the set temperature with the correction value to obtain the target temperature. Thus, the target temperature can be gradually brought close to the set temperature in accordance with the decrease in the air conditioning load. As a result, the comfort of the biological body CR can be gradually improved while reducing the power consumption of the air conditioner 1.

[0215] (Third Modification of Implementation)

[0216] The target temperature in the power-saving cooling mode may be changed according to the temperature of the surface of the living body CR (body surface temperature).

[0217] In the power-saving cooling mode, the control unit 3 receives the detection result indicating the position of the biological CR from the biological sensor 2. The control unit 3 receives the temperature scan data of the area near the position of the biological CR of the indoor RM from the body surface temperature sensor 8. The control unit 3 cuts out the part of the position of the biological CR in the temperature scan data, and obtains the body surface temperature based on the temperature data of the cut-out part. The control unit 3 obtains a correction value based on the body surface temperature.

[0218] At this time, correction information for the power-saving cooling mode as shown Fig.14 may also be set in the control unit 3. Fig.14 FIG. is a diagram showing correction information for the power-saving cooling mode according to the third modification of the embodiment.

[0219] In the correction information for the power-saving cooling mode, the body surface temperature range is associated with the correction value for a plurality of body surface temperature ranges. In Fig.14 this case, it is determined that the correction value increases stepwise in correspondence with the case where the body surface temperature becomes lower.

[0220] By referring to the correction information, the control unit 3 can obtain a correction value corresponding to the body surface temperature in the power-saving cooling mode. The control unit 3, when receiving the set temperature indicated by the operation terminal 94a, corrects the set temperature with the correction value to obtain the target temperature.

[0221] In Fig.14 this case, if the body surface temperature is T1 or higher, the correction value obtained according to the correction information is +1°C. If the body surface temperature is T2 (<T1) or higher and less than T1, the correction value obtained according to the correction information is +2°C. If the body surface temperature is less than T2, the correction value obtained according to the correction information is +3°C.

[0222] Thus, in the third modification of the embodiment, the air conditioner 1 changes the target temperature according to the body surface temperature in the power-saving cooling mode. For example, in the power-saving cooling mode, the air conditioner 1 increases the correction value stepwise in correspondence with the case where the body surface temperature becomes lower, and corrects the set temperature with this correction value to obtain the target temperature. As a result, the target temperature can be made to deviate from the set temperature stepwise in correspondence with the case where the body surface temperature becomes lower. As a result, it is possible to maintain the comfort of the biological CR while reducing the power consumption of the air conditioner 1 stepwise.

[0223] (Fourth modification of the embodiment)

[0224] It is also possible to change the target temperature in the power-saving heating mode according to the temperature of the surface of the biological CR (body surface temperature).

[0225] In the power-saving heating mode, the control unit 3 receives the detection result indicating the position of the biological CR from the biological sensor 2. The control unit 3 receives the temperature scan data of the area near the position of the biological CR of the indoor RM from the body surface temperature sensor 8. The control unit 3 cuts out the part of the temperature scan data at the position of the biological CR, and obtains the body surface temperature based on the temperature data of the cut-out part. The control unit 3 obtains a correction value based on the body surface temperature.

[0226] At this time, correction information for the power-saving heating mode as shown Fig.15 may also be set in the control unit 3. Fig.15 FIG. is a diagram showing correction information for the power-saving heating mode according to the fourth modification of the embodiment.

[0227] In the correction information for the power-saving heating mode, the body surface temperature division and the correction value are made to correspond to each other for a plurality of body surface temperature divisions. In Fig.15 the case, it is determined that the correction value is made to decrease stepwise (the absolute value increases) correspondingly to the case where the body surface temperature becomes higher.

[0228] By referring to the correction information, the control unit 3 can obtain a correction value corresponding to the body surface temperature in the power-saving heating mode. The control unit 3 is such that when the set temperature indicated by the operation terminal 94a is received, the set temperature can be corrected with the correction value to obtain the target temperature.

[0229] In Fig.15 the case, if the body surface temperature is T11 or higher, the correction value obtained according to the correction information is -3°C. If the body surface temperature is T12 (<T11) or higher and less than T11, the correction value obtained according to the correction information is -2°C. If the body surface temperature is less than T12, the correction value obtained according to the correction information is -1°C.

[0230] In this way, in the fourth modification of the embodiment, the air conditioner 1 changes the target temperature according to the body surface temperature in the power-saving heating mode. For example, in the power-saving heating mode, the air conditioner 1 makes the correction value decrease stepwise (the absolute value increases) correspondingly to the case where the body surface temperature becomes higher, and corrects the set temperature with this correction value to obtain the target temperature. As a result, the target temperature can be made to move away from the set temperature stepwise correspondingly to the case where the body surface temperature becomes higher. As a result, it is possible to reduce the power consumption of the air conditioner 1 stepwise while maintaining the comfort of the biological CR.

[0231] (Fifth modification of the embodiment)

[0232] The air volume in the power-saving cooling mode may also be an air volume different from the set air volume indicated by the operation terminal 94a.

[0233] For example, the air conditioner 1 can also perform cooling operation at a target air volume stronger than the set air volume in the power-saving cooling mode.

[0234] In the power-saving cooling mode, the control unit 3 receives an instruction of the set air volume from the operation terminal 94a. The control unit 3 obtains a target air volume stronger than the set air volume. If the air volume can be set in multiple levels, the control unit 3 can also change the level number indicated by the instruction of the set air volume to the stronger side and set the changed level number as the target air volume. The changed level number can also be determined fixedly (for example, +1 level). The control unit 3 rotates the fan 23 at a rotational speed corresponding to the target air volume. Thereby, the air conditioner 1 can perform cooling operation at a target air volume stronger than the set air volume in the power-saving cooling mode.

[0235] Alternatively, the air conditioner 1 can also perform cooling operation at a target air volume determined according to the temperature difference in the power-saving cooling mode.

[0236] In the power-saving cooling mode, the control unit 3 receives the detection result indicating the room temperature from the room temperature sensor 7 and receives an instruction of the set temperature from the operation terminal 94a. The control unit 3 obtains the difference between the room temperature and the set temperature and calculates the temperature difference. The control unit 3 determines the change level number of the reference air volume according to the temperature difference. The reference air volume is the air volume serving as the reference for change. When receiving the set air volume indicated by the operation terminal 94a, the reference air volume can also be the set air volume indicated by the operation terminal 94a. When receiving the automatic air volume indicated by the operation terminal 94a, the reference air volume can also be the air volume at the center of multiple levels.

[0237] The air volume can be set in multiple levels, and the larger the level number, the stronger the corresponding air volume. The control unit 3 can also determine that the change level number decreases step by step corresponding to the case where the temperature difference becomes smaller. It can also be that if the temperature difference is D1 or more, the change level number is determined to be +3 levels, if the temperature difference is D2 (<D1) or more and less than D1, the change level number is determined to be +2 levels, and if the temperature difference is less than D2, the change level number is determined to be +1 level.

[0238] The control unit 3 can change the reference air volume according to the change level number to obtain the target air volume. The control unit 3 rotates the fan 23 at a rotational speed corresponding to the target air volume. Thereby, the air conditioner 1 can perform cooling operation at a target air volume determined according to the temperature difference in the power-saving cooling mode.

[0239] Alternatively, the air conditioner 1 can also perform cooling operation at a target air volume determined according to the distance to the living body CR in the power-saving cooling mode.

[0240] In the power-saving cooling mode, the control unit 3 receives the detection result of the biological sensor 2 and calculates the distance to the biological body CR based on the detection result. Fig. 9 (b) Fig.10 In the case shown in (b), the control unit 3 calculates the distance to the biological body CR based on the detection result of the biological sensor 2, according to the XY distance from the biological sensor 2 to the horizontal position P12b and the difference between the Z height of the biological sensor 2 and the Z height of the position P13b.

[0241] The air volume can be set in multiple levels, and the larger the level number, the stronger the air volume. The control unit 3 may also decide to increase the number of change levels in stages according to the distance to the biological body CR. Considering that the perceived temperature decreases by 1 degree for every 1 meter of wind speed, the control unit 3 may also control the wind speed to be above a specified speed (for example, above 1 m / s) at the location where the biological body CR is located.

[0242] The control unit 3 can change the reference air volume according to the change level number to obtain the target air volume. The control unit 3 rotates the fan 23 at a rotation speed corresponding to the target air volume. Thus, the air conditioner 1 can perform cooling operation at the target air volume determined according to the distance to the biological body CR in the power saving cooling mode.

[0243] Alternatively, the air conditioner 1 can also accept the clothing setting related to the clothing of the biological body CR, and perform cooling operation in the power-saving cooling mode with the wind direction and wind volume determined according to the clothing setting. That is, the air conditioner 1 can also perform cooling operation with the wind direction and wind volume determined according to the information related to the set clothing amount (not limited to the clothing amount, including numbers, characters, and graphics corresponding to the clothing amount).

[0244] Figure 7 The operation terminal 94a shown may also be configured to display the power saving mode setting screen on the display unit 949 when the pressing of a button for instructing to call the power saving mode setting screen (for example, a long pressing of the power saving setting button 9412) is detected. Fig.16 The power saving mode setting screen image 9491 shown in (a) . Fig.16 It is a diagram showing the operation of the display unit 949 of the operation terminal according to the fifth modification example of the embodiment. Fig.16 (a)~ Fig.16 (d) shows a transition to the power saving mode setting screen 9491. The power saving mode setting screen 9491 is a screen for setting information used in the power saving cooling mode or the power saving heating mode.

[0245] Fig.16The power saving mode setting screen 9491 shown in (a) is the initial screen. The power saving mode setting screen 9491 has a clothing setting bar 9492 and an energy saving bar 9495. The clothing setting bar 9492 includes an upper clothing setting bar 9496 and a lower clothing setting bar 9497. The upper clothing setting bar 9496 includes a button 9496. The current upper clothing setting (e.g., "thick clothes") is displayed in button 9496. The lower clothing setting bar 9497 includes a button 9497. The current lower clothing setting (e.g., "normal") is displayed in button 9497. The energy saving bar 9495 includes a button 9498. The current energy saving setting (e.g., "large") is displayed in button 9498.

[0246] exist Fig.16 When the power saving mode setting screen 9491 shown in (a) is displayed on the display unit 949, when the pressing of the ▽ button of the power saving setting button 9412 is detected, the operation terminal 94a Fig.16 The power saving mode setting screen 9491 shown in (b) is displayed on the display unit 949. Fig.16 In the power saving mode setting screen 9491 shown in (b), a pull-down menu 9496a is displayed below the button 9496. The pull-down menu 9496a includes "thick clothes", "normal clothes", "thin clothes", and "short sleeves" as candidates for the upper clothing setting. Fig.16 (b) shows that button 9496 is highlighted and selected, but the operation terminal 94a can sequentially highlight each candidate in the drop-down menu 9496a whenever the ▽ button of the power saving setting button 9412 is pressed, and select the highlighted candidate when the △ button of the power saving setting button 9412 is pressed. When "thin clothes" is selected in the drop-down menu 9496a, the operation terminal 94a changes the display of button 9496 from "thick clothes" to "thin clothes".

[0247] Furthermore, when the operation terminal 94a detects that the ▽ button of the power saving setting button 9412 is pressed, Fig.16 The power saving mode setting screen 9491 shown in (c) is displayed on the display unit 949. Fig.16 In the power saving mode setting screen 9491 shown in (c), a pull-down menu 9497a is displayed below the button 9497. The pull-down menu 9497a includes "thick clothes", "normal clothes", "thin clothes", and "shorts" as candidates for the lower clothing setting. Fig.16(c) of FIG. 1 shows a case where button 9497 is highlighted and selected, but operation terminal 94a can sequentially highlight each candidate in drop-down menu 9497a whenever the ▽ button of power saving setting button 9412 is pressed, and select the highlighted candidate when the △ button of power saving setting button 9412 is pressed. When "thin clothes" is selected in drop-down menu 9497a, operation terminal 94a changes the display of button 9497 from "normal" to "thin clothes".

[0248] Furthermore, when the operation terminal 94a detects that the ▽ button of the power saving setting button 9412 is pressed, Fig.16 The power saving mode setting screen 9491 shown in (d) is displayed on the display unit 949. Fig.16 In the power saving mode setting screen 9491 shown in (d) of FIG. 1 , a pull-down menu 9498a is displayed below the button 9498. The pull-down menu 9498a includes "large", "medium", and "small" as candidates for the amount of power saving. Fig.16 (d) of FIG. 1 shows that button 9498 is highlighted and selected, but operation terminal 94a can sequentially highlight each candidate in drop-down menu 9497a whenever the ▽ button of power saving setting button 9412 is pressed, and select the highlighted candidate when the △ button of power saving setting button 9412 is pressed. When "medium" is selected in drop-down menu 9498a, operation terminal 94a changes the display of button 9498 from "large" to "medium".

[0249] Then, the operation terminal 94a closes the power saving mode setting screen 9491 and displays a normal screen on the display unit 949. At the same time, the dressing setting information and the power saving setting information set in the dressing setting column 9492 and the power saving column 9495 are respectively transmitted from the operation terminal 94a to the control unit 3 via the receiving device 94.

[0250] In the power-saving cooling mode, the control unit 3 determines the wind direction and target air volume according to the clothing setting information when receiving the clothing setting information. In the power-saving cooling mode, the control unit 3 performs cooling operation according to the wind direction and target air volume while tracking the position of the biological body CR.

[0251] For example, the control unit 3 sets the wind direction to the face of the biological body CR according to the upper clothing setting = "thick clothing" and the lower clothing setting = "thick clothing", and changes the reference air volume to the strong side to set it as the target air volume. The reference air volume is the air volume that serves as the reference for the change. In the case of receiving the set air volume indicated by the operation terminal 94a, the reference air volume may also be the set air volume indicated by the operation terminal 94a. In the case of receiving the automatic air volume indicated by the operation terminal 94a, the reference air volume may also be the central air volume of multiple levels.

[0252] The control unit 3 sets the wind direction toward the face of the living body CR based on the upper clothing setting = "thin clothing" and the lower clothing setting = "thin clothing", and changes the reference air volume to the weak side to set it as the target air volume.

[0253] The control unit 3 sets the wind direction toward the upper body of the biological subject CR according to the upper clothing setting = "thick clothes", "normal" or "thin clothes" and the lower clothing setting = "shorts", and changes the reference air volume to the weak side to set it as the target air volume.

[0254] The control unit 3 sets the wind direction toward the lower body of the living body CR according to the upper clothing setting = "short sleeves" and the lower clothing setting = "thick clothes", "normal clothes" or "thin clothes", and changes the reference air volume to the weak side to set it as the target air volume.

[0255] In this way, the air-conditioning apparatus 1 can perform cooling operation in the power-saving cooling mode with the wind direction and target air volume determined according to the clothing setting.

[0256] In addition, the dressing setting information may be automatically generated. For example, when the indoor unit 10 has a camera (not shown), the control unit 3 receives the detection result indicating the position of the biological body CR from the biological sensor 2. The control unit 3 captures the area near the position of the biological body CR in the room RM through the camera and obtains the image of the biological body CR from the camera. The control unit 3 may also automatically identify the clothing of the biological body CR from the image and generate the dressing setting information based on the identification result.

[0257] In the power-saving cooling mode, the control unit 3 may further determine the target temperature according to the power-saving setting information when receiving the power-saving setting information. In the power-saving cooling mode, the control unit 3 performs cooling operation at the target temperature while tracking the position of the biological body CR.

[0258] Based on the power saving = "large", the control unit 3 sets the correction value = +3°C and (set temperature) + 3°C = (target temperature).

[0259] Based on the power saving = "medium", the control unit 3 sets the correction value = +2°C and (set temperature) + 2°C = (target temperature).

[0260] The control unit 3 sets the correction value = +1°C and (set temperature) + 1°C = (target temperature) based on the power saving = "small".

[0261] In the power-saving heating mode, the control unit 3 may further determine the target temperature according to the power-saving setting information when receiving the power-saving setting information. In the power-saving heating mode, the control unit 3 performs heating operation at the target temperature while tracking the position of the biological body CR.

[0262] Based on the power saving = "large", the control unit 3 sets the correction value = -3°C and (set temperature) - 3°C = (target temperature).

[0263] The control unit 3 sets the correction value = -2°C and (set temperature) - 2°C = (target temperature) based on the power saving = "medium".

[0264] The control unit 3 sets the correction value = -1°C and (set temperature) - 1°C = (target temperature) based on the power saving = "small".

[0265] (Sixth Modification of Implementation Method)

[0266] In the power-saving cooling mode, the control unit 3 may also be configured to, when the biosensor 2 detects a plurality of biometric bodies CR, determine a biometric body CR that satisfies a predetermined condition among the plurality of biometric bodies CR, lock the determined biometric body CR, and perform air blowing control and power-saving control. The air blowing control includes controlling the movement of the wind direction plates 4 and 5 in the direction of blowing toward the biometric body CR. The power-saving control includes controlling the cooling operation at a target temperature lower than the set temperature. In this case, the predetermined condition may also be Fig.17 or Fig.18 Conditions as shown. Fig.17 as well as Fig.18 Each of them is a plan view showing air blowing control of the indoor unit 10 of the air-conditioning apparatus 1 according to the sixth modified example of the embodiment.

[0267] exist Fig.17 In the case of (a), when the indoor unit 10 receives the instruction to turn on the power-saving cooling mode from the operation terminal 94a through the receiving device 94, the indoor unit 10 detects the positions of the multiple biological bodies CR1 to CR3 in the indoor RM and the position of the operation terminal 94a through the biological body sensor 2. Based on the detection result of the biological body sensor 2, the control unit 3 determines the biological body that is closest to the operation terminal 94a in space among the multiple biological bodies CR1 to CR3 as the biological body CR1, and locks the biological body CR1. Thereafter, as Fig.17 As shown in (b) of FIG. 1 , the control unit 3 performs control such as blowing control while tracking the living body CR1.

[0268] In addition, the control unit 3 may replace the locked object accordingly if the biological body closest to the operation terminal 94a in space among the plurality of biological bodies CR1 to CR3 is replaced. For example, the control unit 3 may replace the biological body CR1 with the biological body CR2 when the biological body closest to the operation terminal 94a in space among the plurality of biological bodies CR1 to CR3 is determined to be the biological body CR2 while the biological body CR1 is locked and tracked. Thereafter, the control unit 3 performs the blowing control and the like while tracking the biological body CR2 until the biological body closest to the operation terminal 94a in space is replaced again.

[0269] exist Fig.17 In case (c), when the indoor unit 10 receives the instruction to turn on the power-saving cooling mode from the operation terminal 94a through the receiving device 94, the position of the multiple biological bodies CR1 to CR3 in the indoor RM and the distance to the multiple biological bodies CR1 to CR3 are detected by the biological body sensor 2. Based on the detection result of the biological body sensor 2, the control unit 3 determines the biological body that is closest to the biological body sensor 2 (or the indoor unit 10) in space among the multiple biological bodies CR1 to CR3 as the biological body CR2, and locks the biological body CR2. Thereafter, as Fig.17 As shown in (d) of FIG. 1 , the control unit 3 performs control such as blowing control while tracking the living body CR2.

[0270] In addition, the control unit 3 may replace the locked object accordingly if the biological body closest to the biological sensor 2 (or the indoor unit 10) in space among the plurality of biological bodies CR1 to CR3 is replaced. For example, the control unit 3 may replace the biological body CR2 with the biological body CR1 when the biological body closest to the biological sensor 2 (or the indoor unit 10) in space among the plurality of biological bodies CR1 to CR3 is determined to be the biological body CR1 while the biological body CR2 is locked and tracked. Thereafter, the control unit 3 performs the blowing control and the like while tracking the biological body CR1 until the biological body closest to the biological sensor 2 (or the indoor unit 10) in space is replaced again.

[0271] Alternatively, a predetermined detection pattern of the biosensor 2 corresponding to the instruction to turn on the power-saving cooling mode is pre-registered in the control unit 3. The indoor unit 10 detects the gesture of the biological body in the room through the biosensor 2. The control unit 3 determines whether the pattern of the detected gesture is consistent with the predetermined detection pattern. If consistent, it can be determined that the power-saving cooling mode is instructed to be turned on. In response, the control unit 3 can change the control mode to the power-saving cooling mode. Thus, even if the biological body CR is not accustomed to the operation of the operation terminal 94a, it is possible to instruct to turn on the power-saving cooling mode.

[0272] exist Fig.18 In the case of (a), when the indoor unit 10 detects the instruction based on the gesture to turn on the power-saving cooling mode through the biosensor 2, the position of the biometric CR1 making the gesture is detected through the biometric sensor 2. The control unit 3 locks the biometric CR1 making the gesture based on the detection result of the biometric sensor 2. Thereafter, as Fig.18 As shown in (b) of FIG. 1 , the control unit 3 performs control such as blowing control while tracking the living body CR1.

[0273] exist Fig.18 In case (c), when the indoor unit 10 receives an instruction to turn on the power-saving cooling mode from the operation terminal 94a through the receiving device 94, the indoor unit 10 detects the positions of the multiple biological bodies CR1 to CR3 in the indoor RM and the movement amount of the multiple biological bodies CR1 to CR3 through the biological body sensor 2. The movement amount can be the movement amount per unit time or the movement speed at the moment of detection. Fig.18 In (c), the movement amount of each biological body CR1 to CR3 is represented by the distance from the position indicated by the dotted line to the position indicated by the solid line (the movement distance within a predetermined time as indicated by the dotted arrow). The control unit 3 determines the biological body with the largest movement amount among the plurality of biological bodies CR1 to CR3 as the biological body CR3 based on the detection result of the biological body sensor 2, and locks the biological body CR3. Thereafter, as shown in FIG. Fig.18 As shown in (d) of FIG. 1 , the control unit 3 performs the blowing control and the like while tracking the living body CR3. Fig.18 In addition to the control exemplified in (c), a control may be performed in which, based on the detection result of the biosensor 2 , a living body with the largest amount of movement among the living bodies approaching the biosensor 2 is locked.

[0274] Thus, the air conditioner 1 can identify a biological body that satisfies a predetermined condition among the plurality of biological bodies when the biological body sensor 2 detects a plurality of biological bodies CR (for example, biological bodies CR1 to CR3). In the power-saving cooling mode, the air conditioner 1 can perform power-saving control of cooling operation at a target temperature lower than the set temperature while performing air blowing control so that the wind direction plates 4 and 5 are directed toward the position of the identified biological body CR.

[0275] In the power-saving heating mode, the control unit 3 may also similarly determine a biometric CR that satisfies a predetermined condition among the plurality of biometric CRs when a plurality of biometric CRs are detected by the biometric sensor 2, and lock the determined biometric CR to perform blowing control and power-saving control.

[0276] (Seventh Modification of Implementation Method)

[0277] In the power-saving cooling mode, the control unit 3 may also be configured to release the power-saving cooling mode when the number of biometric CRs detected by the biometric sensor 2 exceeds a specified number. For example, in the power-saving cooling mode, when the control unit 3 receives the detection result of the biometric sensor 2, it is possible to determine the number of biometric CRs based on the detection result of the biometric sensor 2. The control unit 3 compares the determined number of biometric CRs with a specified number (for example, 4 persons). If the number of biometric CRs exceeds the specified number, the control unit 3 releases the power-saving cooling mode. Figure 8 As shown in the square brackets, the control mode is switched from the power-saving cooling mode to the normal control mode.

[0278] Thus, when the number of biometrics CR detected by the biometric sensor 2 exceeds a predetermined number in the power-saving cooling mode, the air-conditioning apparatus 1 switches the power-saving cooling mode to the normal control mode, and can perform cooling operation at a set temperature in the normal control mode.

[0279] Similarly, in the power-saving heating mode, the control unit 3 may also cancel the power-saving heating mode when the number of biometric CRs detected by the biometric sensor 2 exceeds a specified number. For example, in the power-saving heating mode, when the control unit 3 receives the detection result of the biometric sensor 2, it can determine the number of biometric CRs based on the detection result of the biometric sensor 2. The control unit 3 compares the determined number of biometric CRs with a specified number (for example, 4 persons). If the number of biometric CRs exceeds the specified number, the control unit 3 cancels the power-saving heating mode. Figure 8 As shown in the square brackets, the control mode is switched from the power-saving heating mode to the normal control mode.

[0280] Thus, when the number of biometrics CR detected by the biometric sensor 2 exceeds a predetermined number in the power-saving heating mode, the air-conditioning apparatus 1 switches the power-saving heating mode to the normal control mode, and can perform heating operation at a set temperature in the normal control mode.

[0281] (Eighth Modification of Implementation Method)

[0282] In the power-saving cooling mode, when a plurality of living bodies CR are detected by the biosensor 2 , the control unit 3 may determine the direction range of the plurality of living bodies CR and swing the wind direction plates 4 and 5 within the direction range.

[0283] In the power-saving cooling mode (third mode), the control unit 3 may respectively determine the positions of the plurality of biological bodies CR when the biological sensor 2 detects a plurality of biological bodies CR, and sequentially select the positions of the plurality of biological bodies CR to perform blowing control and power-saving control. The blowing control includes controlling the movement of the wind deflectors 4 and 5 toward the direction of the positions blowing toward the biological bodies CR. The blowing control for sequentially selecting the positions of the plurality of biological bodies CR includes controlling the wind deflectors 4 and 5 to swing within the direction range of the plurality of biological bodies CR. The power-saving control includes controlling the cooling operation at a target temperature higher than the set temperature. At this time, the blowing control may also be Fig.19 Control as shown. Fig.19 Each of the diagrams is a plan view showing air blowing control of the indoor unit 10 of the air-conditioning apparatus 1 according to the eighth modified example of the embodiment.

[0284] exist Fig.19 In the case of (a), when the control unit 3 receives the instruction to turn on the power-saving cooling mode from the operation terminal 94a through the receiving device 94, the control unit 3 detects the positions of the plurality of biometrics CR1 to CR3 in the room RM and the position of the operation terminal 94a through the biometric sensor 2. The control unit 3 determines the biometric CR1 → biometric CR3 → biometric CR2 → biometric CR3 → biometric CR1 as the selection order of the positions of the plurality of biometrics CR1 to CR3 based on the detection result of the biometric sensor 2.

[0285] In the determined order, such as Fig.19 As shown in (b) of FIG. 1 , the control unit 3 selects the living body CR1 and performs blowing control and power saving control so that the wind direction plates 4 and 5 are directed toward the position where the air blows toward the living body CR1 .

[0286] Then, if Fig.19 As shown in (c) of FIG. 1 , the control unit 3 selects the living body CR3 and performs blowing control and power saving control so that the wind direction plates 4 and 5 are directed toward the position where the air blows toward the living body CR3 .

[0287] Then, if Fig.19 As shown in (d) of FIG. 1 , the control unit 3 selects the living body CR2 and performs blowing control and power saving control so that the wind direction plates 4 and 5 are directed toward the position where the air blows toward the living body CR2.

[0288] Then, if Fig.19 As shown in (c) of FIG. 1 , the control unit 3 selects the living body CR3 and performs blowing control and power saving control so that the wind direction plates 4 and 5 are directed toward the position where the air blows toward the living body CR3 .

[0289] Then, if Fig.19As shown in (b) of FIG. 1 , the control unit 3 selects the living body CR1 and performs blowing control and power saving control so that the wind direction plates 4 and 5 are directed toward the position of blowing the living body CR3 .

[0290] Thereafter, the control unit 3 sequentially selects the positions of the plurality of living bodies CR1 to CR3 in the determined order, and repeatedly performs the air blowing control and the power saving control.

[0291] In addition, the control unit 3 may also determine the positions of the organisms CR at both ends of the movable range of the wind deflector 5 among the multiple organisms CR when multiple organisms CR are detected by the organism sensor 2, set the direction range between the two ends of the organisms CR, and perform air blowing control to swing the wind deflector 5 within the direction range.

[0292] The control unit 3 may also set the movable range of the wind deflector 5 to a directional range and perform air blowing control to swing the wind deflector 5 within the directional range when multiple biological bodies CR are detected by the biological sensor 2 and the positions of some of the multiple biological bodies CR are outside the movable range of the wind deflector 5.

[0293] As described above, when the biosensor 2 detects a plurality of biometric bodies CR (for example, biometric bodies CR1 to CR3), the air conditioning device 1 can identify the direction ranges of the plurality of biometric bodies CR and swing the air direction plates 4 and 5 within the direction ranges.

[0294] In addition, the air conditioning device 1 can also combine the power saving heating mode and the windless mode. For example, the ventilation component 26 can be in the open position ( Figure 3 The air outlet 33 (first flow path C1) is switched between the open position (a position in which the air outlet member 26 is rotated about the X axis to block the air outlet 33 (first flow path C1)).

[0295] When the windless mode is on, Figure 3 As shown, the ventilation component 26 is switched to the closed position. In the closed position, the ventilation component 26 can form a first blow-out flow path (first flow path C1) in which the wind sent by the fan 23 is discharged to the outside through the vent 56, and a second blow-out flow path (second flow path C2) that is discharged to the outside adjacent to the first blow-out flow path (first flow path C1) without passing through the vent 56. That is, the ventilation component 26 is inserted into a part of the flow path of the conditioned air blown into the room in a state switched to the closed position, and the opening rate of a part of the flow path is changed.

[0296] In this case, the flow velocity of wind W2a becomes faster in accordance with the decrease in the opening rate of the first flow path C1. Therefore, wind W2a attracts wind W1a. Thus, wind W1a collides with wind W2a. In addition, wind W2a converted into turbulent flow diffuses, thereby colliding with wind W1a flowing adjacent to wind W2a. In this way, wind W1a and wind W2a with different flow velocities and states (laminar flow or turbulent flow) flow adjacent to each other and collide with each other. That is, wind W1a that does not pass through the ventilation component 26 (vent 56) interferes with wind W2a that passes through the ventilation component 26 (vent 56).

[0297] The wind W1a and the wind W2a collide with each other, so that, for example, clumps of the wind W1a and the wind W2a are broken, and the wind W2a as turbulent flow is delivered to the wind W1a. The wind W1a and the wind W2a produce such various interactions to generate turbulent flow Ws (mixed wind) that spreads over a wide range. As a result, the turbulent flow Ws discharged from the indoor unit 10 becomes closer to natural wind (so-called wind without wind feeling) than the wind immediately after being discharged from the air outlet 33.

[0298] The control unit 3 detects the position of the living body CR, locks the living body CR, and switches the ventilation member 26 to the closed position when (control mode, operation mode, auxiliary operation mode) = (power saving heating mode, heating mode, no wind mode on). The control unit 3 controls the wind direction plates 4 and 5 to face the foot of the living body CR while tracking the position of the living body CR, and performs heating operation at the target temperature.

[0299] Thus, the wind direction can be controlled so that the wind blown from the indoor unit 10 reaches the feet of the living body CR in a state close to natural wind (so-called windless wind) while tracking the locked living body CR. By making the windless wind reach the feet of the living body CR, the living body CR is surrounded by warm windless wind (diffused soft wind) from the feet, and the body temperature of the living body CR can be effectively increased. As a result, in the combination of the power-saving heating mode and the windless mode, the body temperature of the living body CR can be made close to the set temperature while performing heating operation at the target temperature.
