Description

Air Conditioning Systems and Controls

[0001] The present disclosure relates to an air conditioning system and a control device.

In this device, the inhibitor is diffused from a diffusing unit toward the target space, thereby inhibiting the activity of insects present in the target space.

[0003] JP 2024-11598 A

[0004] An air conditioning unit for conditioning the target space where the inhibitor is diffused as disclosed in Patent Document 1 may be installed. The operation of the air conditioning unit affects the effect of the inhibitor in the target space. Despite this, the air conditioning unit has conventionally been operated without considering the operation of the diffusion unit that diffuses the inhibitor.

[0005] The present disclosure provides an air conditioning system that can exert the effect of an inhibitor in a dissipation unit.

[0006] The first aspect relates to an air conditioning system. The air conditioning system includes an air conditioning unit (U1) that conditions a target space (S), a dissipation unit (U2) that dissipates an inhibitor that inhibits insect activity into the target space (S), and a controller (100) that controls the air conditioning unit (U1) in conjunction with the dissipation operation of the dissipation unit (U2) when the dissipation unit (U2) dissipates the inhibitor into the target space (S). The term "air conditioning" as used herein refers to air temperature adjustment, air purification, and ventilation.

[0007] In the first aspect, the controller (100) controls the air conditioning unit (U1) in conjunction with the dissipation operation of the dissipation unit (U2), thereby enabling the air conditioning unit (U1) to be operated in consideration of the operation of the dissipation operation. Therefore, the air conditioning system can be operated in a manner that allows the inhibitor to exert its effect.

[0008] In the second aspect, in the first aspect, the air conditioning unit (U1) is an air conditioner (10) that adjusts the temperature of air in the target space (S).

[0009] In the second mode, the controller (100) controls the air conditioner (10) to adjust the temperature of the air in conjunction with the dissipation operation of the dissipation unit (U2).

[0010] In the third aspect, in the second aspect, the controller (100) increases the volume of air blown out from the air conditioner (10) in conjunction with the dissipation operation of the dissipation unit (U2).

[0011] In the third aspect, when the dissipation unit (U2) dissipates the inhibitor into the target space (S), the volume of the air blown out from the air conditioner (10) is increased, thereby improving the dissipation effect of the inhibitor in the target space (S) by the blown out air.

[0012] In a fourth aspect, in the first aspect, the air conditioning unit (U1) is an air purifier (40) that purifies the air in the target space (S).

[0013] In the fourth aspect, the controller (100) controls the air purifier (40) that purifies air in conjunction with the dissipation operation of the dissipation unit (U2).

[0014] In a fifth aspect, in the fourth aspect, the air purifier (40) includes an air flow path (43) that draws in air from a target space (S) and supplies the air to the target space (S), a purifying section (50) that is disposed in the air flow path (43) and purifies the air, and an adjusting section (42, 42A, 42B, 60) that adjusts the flow rate of air passing through the purifying section (50). The controller (100) controls the adjusting section (42, 42A, 42B, 60) in conjunction with the dissipation operation of the dissipation unit (U2) so as to reduce the flow rate of air passing through the purifying section (50).

[0015] In the fifth aspect, when the diffusion unit (U2) diffuses the inhibitor into the target space (S), the flow rate of air passing through the purification section (50) of the air purifier (40) is reduced. As a result, the inhibitor diffused into the target space (S) can be prevented from being decomposed or removed by the purification section (50) of the air purifier (40). As a result, the effect of the inhibitor can be prevented from being impaired during operation of the air purifier (40).

[0016] In a sixth aspect, in the fifth aspect, the air flow path (43) has a first flow path (43a) for sending air from the target space (S) to the target space (S) through the purification section (50) and a second flow path (43b) for sending the air from the target space (S) to the target space (S) without passing through the purification section (50). The adjustment sections (42A, 42B, 60) are configured to adjust the air flow rate of the first flow path (43a) and the air flow rate of the second flow path (43b). The controller (100) controls the adjustment sections (42A, 42B, 60) in conjunction with the dissipation operation of the dissipation unit (U2) so that the air flow rate of the first flow path (43a) is smaller than the air flow rate of the second flow path (43b).

[0017] In the sixth aspect, the air flow rate in the first flow path (43a) is reduced relative to the air flow rate in the second flow path (43b) in conjunction with the dissipation operation. As a result, the flow rate of air passing through the purifying section (50) in the first flow path (43a) is reduced, thereby suppressing removal of inhibitors in the target space (S) by the purifying section (50). The increased air flow rate in the second flow path (43b) ensures a sufficient flow rate of air blown out from the air purifier (40). This blown out air therefore promotes dissipation of inhibitors in the target space (S).

[0018] In a seventh aspect, in the sixth aspect, the adjustment part (42, 42A, 42B, 60) is an opening / closing mechanism (60) that switches between a first state in which the first flow path (43a) is open and the second flow path (43b) is closed, and a second state in which the first flow path (43a) is closed and the second flow path (43b) is open. The controller (100) switches the opening / closing mechanism (60) to the second state in response to the dissipation operation of the dissipation unit (U2).

[0019] In the seventh aspect, when the diffusion unit (U2) diffuses inhibitors into the target space (S), the first flow path (43a) is closed and the second flow path (43b) is open. The first flow path (43a) is closed, so that the inhibitors diffused into the target space (S) are not removed by the purifying section (50). The second flow path (43b) is open, so that the flow rate of the air blown out from the air purifier (40) can be ensured. This further improves the effect of diffusing inhibitors by the blown out air.

[0020] In an eighth aspect, in any one of the fourth to seventh aspects, the air purifier (40) has an air flow path (43) that draws in air from a target space (S) and supplies the air to the target space (S), and a purifying section (50) that is disposed in the air flow path (43) and purifies the air. The controller (100) reduces the output of the purifying section (50) in conjunction with the dissipation operation of the dissipation unit (U2).

[0021] In the eighth aspect, when the diffusion unit (U2) diffuses the inhibitor into the target space (S), the output of the purification section (50) is reduced, which makes it possible to suppress the inhibitor diffused into the target space (S) from being decomposed or removed by the purification section (50).

[0022] In a ninth aspect, in the first aspect, the air conditioning unit (U1) is a ventilation device (70) that ventilates the target space (S).

[0023] In the ninth aspect, the controller (100) controls the ventilation device (70) that ventilates the target space (S) in conjunction with the dissipation operation of the dissipation unit (U2).

[0024] In a tenth aspect, in the ninth aspect, the controller (100) reduces the ventilation volume of the ventilation device (70) in conjunction with the dissipation operation of the dissipation unit (U2).

[0025] In the tenth aspect, when the dissipation unit (U2) dissipates the inhibitor into the target space (S), the ventilation volume of the ventilation device (70) is reduced, thereby preventing the inhibitor dispersed into the target space (S) from decreasing due to ventilation.

[0026] In the eleventh aspect, in the fifth aspect, the controller (100) controls the adjustment section (42, 42A, 42B, 60) so as to reduce the flow rate of air passing through the purification section (50) in conjunction with the diffusion operation of the diffusion unit (U2), and then, after a predetermined time has elapsed, ends the diffusion operation and controls the adjustment section (42, 42A, 42B, 60) so as to increase the flow rate of air passing through the purification section (50).

[0027] In the twelfth aspect, in the eighth aspect, the controller (100) reduces the output of the purification section (50) in conjunction with the diffusion operation of the diffusion unit (U2), and after a predetermined time has elapsed, ends the diffusion operation and increases the output of the purification section (50).

[0028] In a thirteenth aspect, in the tenth aspect, the controller (100) reduces the ventilation volume of the ventilation device (70) in conjunction with the dissipation operation of the dissipation unit (U2), and after a predetermined time has elapsed, ends the dissipation operation and increases the ventilation volume of the ventilation device (70).

[0029] A fourteenth aspect is directed to a control device, which includes the controller (100) of any one of the first to thirteenth aspects.

[0031] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the embodiments shown below, and various modifications are possible within the scope of the technical concept of the present disclosure. Since the drawings are intended to conceptually explain the present disclosure, dimensions, ratios, or numbers may be exaggerated or simplified as necessary to facilitate understanding.

[0032] (1) Embodiment 1 (1-1) Overall Configuration of Air Conditioning System The air conditioning system (1) diffuses an inhibitor that inhibits the activity of insects (I) into a target space (S) and also conditions the target space (S). The air conditioning system (1) repels insects (I) that have appeared in the target space (S) or creates an environment in the target space (S) that is difficult for insects (I) to live in. This makes it possible to create an environment in the target space (S) where the number of insects (I) is reduced. Here, "inhibiting the activity of insects (I)" includes, for example, reducing the sensitivity of the olfactory or tactile functions of the insects (I) or inhibiting the reproduction of the insects (I).

[0033] As shown in Figure 1, the target space (S) is an indoor space where people stay, such as a bedroom, living room, kitchen, or office in a house. The target insect species that are the target of the air conditioning system (1) are, for example, cockroaches, mites, etc. These target insect species (I) are pests that occur relatively frequently in the target space (S) where people live.

[0034] The air conditioning system (1) includes an air conditioning unit (U1) and a dissipation unit (U2). The air conditioning unit (U1) in this embodiment is an air conditioner (10) that adjusts the temperature of air in a target space (S).

[0035] (1-2) Air Conditioner The air conditioner (10) has an outdoor unit (11) installed outdoors and an indoor unit (20) installed in the target space (S). The outdoor unit (11) and the indoor unit (20) are connected by a refrigerant pipe (12). The air conditioner (10) has a temperature control function. Specifically, the air conditioner (10) performs a cooling operation to cool the air in the target space (S) and a heating operation to heat the air in the target space (S).

[0036] As shown in Fig. 1, the outdoor unit (11) is installed in an outdoor space outside the target space (S). The outdoor unit (11) includes an outdoor casing (13) and outdoor elements housed in the outdoor casing (13). The outdoor elements include a compressor, an outdoor heat exchanger, an expansion valve, a four-way selector valve, and an outdoor fan.

[0037] The indoor unit (20) is a wall-mounted type. Specifically, the indoor unit (20) is installed on the upper part of an interior wall of a building. The indoor unit (20) includes an indoor casing (21), an indoor heat exchanger (22), an indoor fan (23), a flap (24), and an indoor temperature sensor (25).

[0038] The indoor casing (21) is formed in the shape of a horizontally elongated hollow box. The indoor casing (21) has a substantially rectangular cross section. An inlet (21a) is formed in each of the front and top surfaces of the indoor casing (21). An outlet (21b) is formed in the front side of the lower part of the indoor casing (21). An air conditioning passage (26) is formed inside the indoor casing (21) from the inlet (21a) to the outlet (21b).

[0039] The indoor heat exchanger (22) is disposed in the air conditioning passage (26). The indoor heat exchanger (22) functions as an evaporator during cooling operation and as a condenser (radiator) during heating operation. The indoor fan (23) is disposed downstream of the indoor heat exchanger (22) in the air conditioning passage (26). The indoor fan (23) is a cross-flow fan. The indoor fan (23) is a variable air volume fan with a variable motor rotation speed. The indoor fan (23) generates an air flow in the target space (S). The indoor fan (23) generates a flow that circulates air throughout the target space (S). Specifically, when the indoor fan (23) is operated, air blown out from the air outlet (21b) of the indoor unit (20) flows along the floor, wall, and ceiling surfaces facing the target space (S) in that order, and then returns to the air inlet (21a).

[0040] The flap (24) is provided at the air outlet (21b) of the indoor unit (20). The flap (24) extends substantially horizontally along the air outlet (21b). The flap (24) is rotationally driven by a motor (not shown). The flap (24) changes the direction of the air blown out from the air outlet (21b). By changing the position of the flap (24), the air blown out can be directed toward, for example, the floor, wall, or ceiling surface facing the target space (S), or specific furniture.

[0041] The room temperature sensor (25) detects the temperature of air in the target space (S). The room temperature sensor (25) detects the temperature of intake air drawn into the air inlet (21a). The room temperature sensor (25) may be disposed in the target space (S).

[0042] (1-3) Dissipation Unit The dissipation unit (U2) dissipates the inhibitor into the target space (S). The dissipation unit (U2) is placed in the target space (S). The dissipation unit (U2) is installed, for example, on the floor of the target space (S), but may also be installed on a wall or ceiling facing the target space (S).

[0043] The diffusion unit (U2) of this embodiment is a spray type and includes a container (30), an inhibitor source (31) accommodated in the container (30), a transport unit (32) for transporting the inhibitor from the inhibitor source (31), and a supply port (33) for supplying the inhibitor transported by the transport unit (32) to the target space (S).

[0044] The inhibitor source (31) consists of a liquid, gas, or a volatilizable solid. The inhibitor reduces the sensitivity of the olfactory and tactile functions of the insect (I) or inhibits the reproductive ability of the insect (I). By using an inhibitor that has an inhibitory effect on the insect (I), the impact on human health can be reduced.

[0045] The transport unit (32) is composed of, for example, a pump for transporting the inhibitor such as a liquid or gas, and may also be, for example, a power supply unit for electrostatic spraying, an ultrasonic element for ultrasonic spraying, a compressed fluid for transporting the inhibitor by pressure, a shutter that opens to promote volatilization of the solid inhibitor, or a fan for transporting the gaseous inhibitor.

[0046] The supply port (33) is formed, for example, by a spray nozzle for spraying a liquid inhibitor.

[0047] (1-4) Controller and Its Peripheral Elements As shown in FIG. 2, the air conditioning system (1) has a controller (100). The controller (100) includes a processor such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit), an electric circuit, and an electronic circuit. The controller (100) includes a memory device (specifically, a semiconductor memory) that stores software for operating the processor, etc. The controller (100) may be configured as a single physically independent element, or may be configured as two or more physically separated elements.

[0048] The controller (100) of this embodiment includes an air conditioning control section (110) provided in the air conditioning unit (U1) and a dissipation control section (120) provided in the dissipation unit (U2).

[0049] The air conditioning control unit (110) includes an indoor control unit (111) and an outdoor control unit (112). The indoor control unit (111) is provided in the indoor unit (20). The outdoor control unit (112) is provided in the outdoor unit (11). The indoor control unit (111) and the outdoor control unit (112) are connected to each other via a communication line (not shown). The air conditioning control unit (110) controls the compressor, the outdoor fan, the four-way switching valve, the expansion valve, the indoor fan (23), etc. The air conditioning control unit (110) controls the ON / OFF switching of the indoor fan (23) and the rotation speed of the indoor fan (23), in other words, the volume of air blown out or the volume of air sucked in by the air conditioner (10). The air conditioning control unit (110) adjusts the angle of the flap (24).

[0050] The diffusion control unit 120 controls the diffusion unit U2. Specifically, the diffusion control unit 120 controls the diffusion operation of the diffusion unit U2 to diffuse the inhibitor into the target space S. The diffusion control unit 120 may adjust the amount of the inhibitor diffused.

[0051] As shown in Fig. 2, the air conditioning system (1) includes a router (130) that serves as a communication interface. The router (130) is connected to a server device (140) on the cloud via a network (N). The air conditioning control unit (110) is connected to the router (130) via a first wireless or wired communication line (W1), and the emission control unit (120) is connected to the router (130) via a second wireless or wired communication line (W2). In this manner, the air conditioning control unit (110) and the emission control unit (120) are configured to be able to receive a common signal.

[0052] The air conditioning system (1) of this embodiment includes a communication terminal (150). The communication terminal (150) of this embodiment is a smartphone. The communication terminal (150) includes a microcomputer and a memory device. The memory device stores software for operating the microcomputer. The communication terminal (150) is connected to a server device (140) via a network (N).

[0053] The communication terminal (150) is a terminal through which a user operates the air conditioning system (1). The user can operate the air conditioner (10) and the dissipation unit (U2) by operating the communication terminal (150). The operation of the air conditioner (10) includes starting and stopping the operation of the air conditioner (10), switching the operation mode of the air conditioner (10), setting the target temperature of the air conditioner (10), and setting the target air volume of the indoor fan (23). The operation of the dissipation unit (U2) includes starting and stopping the dissipation operation of the dissipation unit (U2) and setting the target dissipation volume of the dissipation unit (U2).

[0054] The air conditioner (10) has a remote controller (115) for operating the air conditioner (10) in addition to the communication terminal (150). By operating the remote controller (115), a user can operate the air conditioner (10) in the same way as the communication terminal (150).

[0055] (2) Operation The operation of the air conditioning system (1) will be described.

[0056] (2-1) Operation of the Air Conditioning Unit (U1) In cooling operation, the air conditioning unit (U1) performs a refrigeration cycle in which the outdoor heat exchanger functions as a radiator (condenser) and the indoor heat exchanger (22) functions as an evaporator. When the indoor fan (23) is operated, air from the target space (S) flows into the air conditioning passage (26) through the air inlet (21a). The air in the air conditioning passage (26) is cooled by the indoor heat exchanger (22) and then supplied to the target space (S) through the air outlet (21b).

[0057] In heating operation, the air conditioning unit (U1) performs a refrigeration cycle in which the indoor heat exchanger (22) functions as a radiator (condenser) and the outdoor heat exchanger functions as an evaporator. When the indoor fan (23) is operated, air from the target space (S) flows into the air conditioning passage (26) through the air inlet (21a). The air in the air conditioning passage (26) is heated by the indoor heat exchanger (22) and then supplied to the target space (S) through the air outlet (21b).

[0058] (2-2) Dispersion Operation of Dispersion Unit (U2) In the dispersal operation, the dispersal unit (U2) disperses the inhibitor into the target space (S). Specifically, by operating a pump or the like, the inhibitor in the container (30) is sprayed into the target space (S). As a result, the inhibitor in the target space (S) inhibits the activity of insects.

[0059] (2-3) Interlocking Control The controller (100) controls the air conditioning unit (U1) and the dissipation unit (U2) in an interlocking manner. This interlocking control will be described with reference to FIG.

[0060] The user uses the communication terminal (150) to operate the dissipation unit (U2) to start the dissipation operation. As a result, the communication terminal (150) outputs a start command to start the dissipation operation. This command (signal) is received by the controller (100) via the network (N). In step ST11, when the controller (100) receives the operation command for the dissipation operation, the process proceeds to step ST12. In step ST12, the controller (100), more specifically, the dissipation control unit (120), starts the dissipation operation of the dissipation unit (U2). As a result, the dissipation unit (U2) dissipates the inhibitor into the target space (S). In step ST13, the controller (100) checks the set airflow rate of the indoor fan (23) for the dissipation operation. Note that this set airflow rate is input in advance to the controller (100) by the user operating the communication terminal (150) or the remote controller (115).

[0061] If the set airflow rate is the maximum airflow rate in step ST14, the process proceeds to step ST15. In step ST15, the controller (100), or more precisely, the air conditioning control unit (110), maximizes the airflow rate of the indoor fan (23) of the air conditioner (10). As a result, the airflow rate of the air blown out from the air conditioner (10) is maximized, and the inhibitors are agitated by the blown out air in the target space (S), thereby improving the inhibitor dissipation effect. Note that in step ST15, the controller (100) maximizes the airflow rate of the indoor fan (23) even if the indoor fan (23) is stopped at the start of the dissipation operation. Furthermore, the controller (100) maximizes the airflow rate of the indoor fan (23) even if the air conditioner (10) is performing normal operation, such as cooling or heating, at the start of the dissipation operation. In this case, the cooling or heating operation continues.

[0062] If the set airflow rate is not the maximum airflow rate in step ST14, the process proceeds to step ST16. In step ST16, the controller (100), or more precisely, the air conditioning control unit (110), increases the airflow rate of the indoor fan (23) of the air conditioner (10) by a predetermined amount. Here, "increasing the airflow rate" includes operating the indoor fan (23) that is stopped, i.e., the indoor fan (23) with zero airflow rate, at a predetermined rotation speed. As a result, the airflow rate of the air conditioner (10) increases, and the inhibitors in the target space (S) are agitated by the airflow rate, thereby improving the inhibitor dissipation effect. In this case, the airflow rate of the indoor fan (23) is controlled to a predetermined airflow rate that is lower than the maximum airflow rate, thereby suppressing noise from the indoor fan (23) and reducing the feeling of draft felt by the user.

[0063] In step S17, when a predetermined time has elapsed since the start of the dissipation operation, the process proceeds to step ST18. In step ST18, the controller (100), more precisely, the dissipation control section (120), terminates the dissipation operation of the dissipation unit (U2). Next, in step ST19, the controller (100), more precisely, the air conditioning control section (110), returns the air volume of the indoor fan (23) to the original air volume before the start of the dissipation operation. Here, "returning to the original air volume" includes the meaning of stopping again the indoor fan (23) that was stopped before the start of the dissipation operation.

[0064] (3) Effects of Embodiment 1 The air conditioning system (1) includes a controller (100) that controls the air conditioning unit (U1) in conjunction with the dissipation operation during the dissipation operation in which the dissipation unit (U2) dissipates the inhibitor into the target space (S). Specifically, the controller (100) increases the air volume of the air blown out from the air conditioner (10) in conjunction with the dissipation operation of the dissipation unit (U2). More specifically, when the air conditioner (10) is in a stopped state, the controller (100) operates the indoor fan (23) of the air conditioner (10) in conjunction with the dissipation operation of the dissipation unit (U2) to set the air volume to a predetermined volume or a maximum volume. When the air conditioner (10) is in operation, the controller (100) increases the air volume of the indoor fan (23) of the air conditioner (10) in conjunction with the dissipation operation of the dissipation unit (U2) to set the air volume to a maximum volume.

[0065] With this configuration, when the dissipation operation is performed, the inhibitors in the target space (S) can be agitated by the air blown out from the air conditioner (10), thereby improving the dissipation effect of the inhibitors and effectively inhibiting insect activity.

[0066] In particular, in step ST15, the controller (100) maximizes the amount of air blown out from the air conditioner (10) in conjunction with the dissipation operation of the dissipation unit (U2), thereby further promoting the dissipation effect of the inhibitor.

[0067] The controller (100) determines whether to maximize the volume of the blown air or increase it by a predetermined amount based on a preset volume of air, and therefore, in the dissipation operation, the volume of the blown air from the air conditioner (10) can be selected arbitrarily in response to a user request.

[0068] The timing of controlling the air conditioning unit (U1) in conjunction with the dissipation operation does not have to be simultaneous with the dissipation operation, but may be immediately before or immediately after the dissipation operation. In other words, the controller (100) may execute the dissipation operation and the control of the air conditioning unit (U1) in a coordinated manner.

[0069] (4) Modification of First Embodiment The controller (100) may swing the flap (24) of the air conditioner (10) in conjunction with the dissipation operation of the dissipation unit (U2). In this case, the change in the direction of the blown air can agitate the inhibitors in the target space (S), thereby improving the inhibitor dissipation effect.

[0070] The controller (100) may increase the temperature of the air blown out from the air conditioner (10) in conjunction with the dissipation operation of the dissipation unit (U2). In this case, the increase in the temperature of the air in the target space (S) can improve the dissipation effect of the inhibitor.

[0071] (5) Second Embodiment An air conditioning system (1) according to a second embodiment will be described. In the following description, differences from the first embodiment will be described.

[0072] (5-1) Configuration of Air Conditioning System The air conditioning unit (U1) of the second embodiment is an air purifier (40) that purifies the air in the target space (S). The air purifier (40) is placed in the target space (S). As shown in FIG. 4 , the air purifier (40) of the second embodiment is a floor-standing type that is installed on the floor, but it may also be a wall-mounted or ceiling-mounted type.

[0073] The air purifier (40) has a first casing (41), and a purifying section (50) and a first fan (42) housed in the first casing (41).

[0074] The first casing (41) is formed in the shape of a hollow box. Two inlets (41a) and one outlet (41b) are formed in the first casing (41). The inlets (41a) are formed in the lower parts of a pair of corresponding side surfaces of the first casing (41). The outlet (41b) is formed in the upper surface of the first casing (41). An air flow path (43) is formed inside the first casing (41) from the two outlets (41b) to the inlet (41a).

[0075] The purifying section (50) is an element that purifies the air in the air flow path (43). In this example, the purifying section (50) includes, for example, a dust collecting filter (51), a discharge unit (52), and a deodorizing filter (53). In the air flow path (43), the dust collecting filter (51), the discharge unit (52), and the deodorizing filter (53) are arranged in this order from the upstream side to the downstream side of the air flow, but the arrangement order of these elements is merely an example. The dust collecting filter (51) captures dust in the air. The dust collecting filter (51) is, for example, a HEPA filter. The discharge unit (52) generates, for example, activated species for decomposing odorous components through discharge. The discharge unit (52) generates, for example, streamer discharge, but may also generate other discharges such as corona discharge or surface discharge. The deodorizing filter (53) removes odorous components from the air. The deodorizing filter (53) includes a substrate and activated carbon supported on the substrate. The elements of the cleaning section (50) are merely examples. The cleaning section (50) may include, for example, an electrostatic precipitator unit and an ultraviolet light generating unit.

[0076] The first fan (42) is arranged upstream of the purifier section (50) in the air flow path (43). The first fan (42) may be arranged downstream of the purifier section (50) in the air flow path (43). The first fan (42) is a variable air volume fan with a variable motor speed. In the second embodiment, the first fan (42) constitutes an adjusting section that adjusts the flow rate of air passing through the purifier section (50).

[0077] The inlet (41a) is provided with a first flap (44) that adjusts the direction of air blown upward from the air flow path (43).

[0078] As shown in Fig. 5, the controller (100) of the second embodiment includes a diffusion control section (120) and a cleaning control section (160). The cleaning control section (160) is provided in the air purifier (40). The cleaning control section (160) controls the ON / OFF switching of the first fan (42) and the rotation speed of the first fan (42), in other words, the volume of intake air or the volume of blown air of the air purifier (40). The cleaning control section (160) adjusts the angle of the first flap (44).

[0079] The purification control unit (160) is connected to the router (130) via a wireless or wired third communication line (W3), and the emission control unit (120) is connected to the router (130) via a wireless or wired second communication line (W2). In this way, the purification control unit (160) and the emission control unit (120) are configured to be able to input a common signal.

[0080] The user can operate the air purifier (40) and the dissipation unit (U2) by operating the communication terminal (150). The operation of the air purifier (40) includes starting and stopping the operation of the air purifier (40), switching the operation mode of the air purifier (40), setting the output of the purification section (50) (e.g., the discharge unit (52)), and setting the target air volume of the first fan (42).

[0081] The air purifier (40) has a first operation unit (165) for operating the air purifier (40) in addition to the communication terminal (150). By operating the first operation unit (165), a user can operate the air purifier (40) in the same way as the communication terminal (150).

[0082] (5-2) Operation (5-2-1) Operation of Air Purifier When the air purifier (40) is in operation, the first fan (42) and the discharge unit (52) are operated. Air from the target space (S) flows into the air flow path (43) through the inlet (41a). This air passes through the dust collection filter (51), the discharge unit (52), and the deodorizing filter (53), in that order. As a result, dust and odor components in the air are removed. The air purified in the air flow path (43) is blown out into the target space (S) through the outlet (41b).

[0083] (5-2-2) Interlocking Control The controller (100) controls the air conditioning unit (U1) and the dissipation unit (U2) in an interlocking manner. This interlocking control will be described with reference to Fig. 6. The following interlocking control is performed while the air purifier (40) is in operation.

[0084] In step ST21, when the controller (100) receives an operation command for the dissipation operation, the process proceeds to step ST22. In step ST22, the controller (100) starts the dissipation operation of the dissipation unit (U2). In step ST23, the controller (100) checks the set air volume of the first fan (42) for the dissipation operation. Note that this set air volume is input in advance to the controller (100) by the user operating the communication terminal (150) or the first operation unit (165).

[0085] If the set airflow rate is OFF (zero) in step ST24, the process proceeds to step ST25. In step ST25, the controller (100), more precisely, the purification control section (160), stops the first fan (42) of the air purifier (40). As a result, the flow rate of air passing through the purification section (50) becomes zero.

[0086] In the dissipation operation, when the first fan (42) is operated at a predetermined air volume, the inhibitors dispersed in the target space (S) are removed by the purifying section (50). Specifically, the inhibitors are trapped in the dust collection filter (51) or the deodorizing filter (53), or are decomposed as the discharge unit (52) discharges. In response to this, by reducing the air volume passing through the purifying section (50) in conjunction with the dissipation operation, specifically by setting it to zero, it is possible to prevent the inhibitors from being removed by the purifying section (50). Therefore, it is possible to prevent the inhibitor dissipation effect from being attenuated as the air purifier (40) operates, and the inhibitors can fully function.

[0087] If the set airflow rate is not OFF (zero) in step ST24, the process proceeds to step ST26. In step ST26, the controller (100), more precisely, the purification control section (160), reduces the airflow rate of the first fan (42) of the air purifier (40) by a predetermined amount and continues to operate the first fan (42). This reduces the flow rate of air passing through the purification section (50), thereby suppressing the removal of inhibitors by the purification section (50). At this time, air continues to flow through the purification section (50), thereby enabling the continuous removal of dust and odorous components from the target space (S).

[0088] In step ST27, when a predetermined time has elapsed since the start of the dissipation operation, the process proceeds to step ST28. In step ST28, the controller (100) terminates the dissipation operation of the dissipation unit (U2). Next, in step ST29, the controller (100), or more precisely, the cleaning control section (160), returns the air volume of the first fan (42) to the original air volume before the start of the dissipation operation. In step ST29, the controller (100) may increase the air volume of the first fan (42) to a predetermined air volume different from the original air volume.

[0089] (5-3) Advantages of Embodiment 2 When the air purifier (40) is in operation, the controller (100) controls the first fan (42) as an adjustment part so as to reduce the flow rate of air passing through the purification part (50) in conjunction with the dissipation operation of the dissipation unit (U2).

[0090] This configuration prevents the inhibitors in the target space (S) from being removed by the purification section (50) during the diffusion operation. As a result, the inhibitors can fully function. In addition, the inhibitors can be prevented from being trapped in the dust collection filter (51) as a filter section or the deodorization filter (53) as an adsorption section, thereby preventing the filter life from being shortened.

[0091] In particular, in step ST25, the controller (100) stops the first fan (42) in conjunction with the dissipation operation, thereby making it possible to fully obtain the above-described effects. Also, in step ST26, the controller (100) reduces the flow rate of air passing through the purification section (50) while operating the first fan (42) in conjunction with the dissipation operation, thereby making it possible to continuously purify the air in the target space (S).

[0092] (6) First Modification of Second Embodiment (6-1) Configuration of Air Conditioning System As shown in Fig. 7 , in the first modification of the second embodiment, the air flow path (43) includes a first flow path (43a), a second flow path (43b), and a main flow path (43c). The first flow path (43a) and the second flow path (43b) are arranged in parallel in the air flow path (43). The inlet end of the first flow path (43a) and the inlet end of the second flow path (43b) are connected to the main flow path (43c). The main flow path (43c) is provided with a first fan (42).

[0093] The first flow path (43a) is provided with a purifying section (50). The second flow path (43b) is not provided with a purifying section (50). The second flow path (43b) serves as a bypass flow path that bypasses the purifying section (50). The main flow path (43c) may be connected to the outlet end of the first flow path (43a) and the outlet end of the second flow path (43b).

[0094] The air purifier (40) has an opening / closing mechanism (60) as an adjustment unit. The opening / closing mechanism (60) has a first damper (60A) and a second damper (60B). The opening / closing mechanism (60) has the first damper (60A) and the second damper (60B). The first damper (60A) is arranged in the first flow path (43a), and the second damper (60B) is arranged in the second flow path (43b). The first damper (60A) is arranged upstream of the purifier section (50) in the first flow path (43a), but may be arranged downstream of the purifier section (50). The second damper (60B) is arranged upstream of the purifier section (50) in the second flow path (43b), but may be arranged downstream of the purifier section (50).

[0095] The first damper (60A) is switchable between an open state for opening the first flow path (43a) and a closed state for closing the first flow path (43a).The second damper (60B) is switchable between an open state for opening the second flow path (43b) and a closed state for closing the second flow path (43b).

[0096] The controller (100), more precisely, the cleaning control section (160), switches the opening / closing mechanism (60) between a first state shown in Fig. 7(A) and a second state shown in Fig. 7(B). In the first state of the opening / closing mechanism (60), the first flow path (43a) is open and the second flow path (43b) is closed. In the second state of the opening / closing mechanism (60), the first flow path (43a) is closed and the second flow path (43b) is open.

[0097] 8, when a command to start the dissipation operation is input to the controller (100) in step ST31 and the dissipation operation is started in step ST32, the controller (100) sets the opening / closing mechanism (60) to the second state in step ST33. If the set airflow rate is set to the maximum (YES in step ST35), the controller (100) sets the airflow rate of the first fan (42) to the maximum in step ST36, regardless of whether the first fan (42) is operating or stopped.

[0098] As shown in FIG. 7(B), air drawn into the air flow path (43) from the target space (S) flows through the second flow path (43b) and bypasses the purifier (50). Therefore, the flow rate of air passing through the purifier (50) becomes zero. This prevents the inhibitors in the target space (S) from being removed by the purifier (50). At this time, the air purifier (40) blows out a maximum volume of air into the target space (S). Therefore, the inhibitors in the target space (S) can be agitated by the air blown out from the air purifier (40), improving the inhibitor dissipation effect.

[0099] If the set airflow rate is not set to the maximum (NO in step ST35), in step ST37, the controller (100) increases the airflow rate of the first fan (42) by a predetermined amount. If the first fan (42) is stopped, the controller (100) operates the first fan (42) to set the airflow rate of the first fan (42) to the predetermined amount. Even in this case, the air drawn into the air flow path (43) from the target space (S) bypasses the purifying section (50), thereby preventing the inhibitors from being removed by the purifying section (50). Additionally, the air blown out from the air purifier (40) can agitate the inhibitors in the target space (S), thereby improving the inhibitor dissipation effect. Because the airflow rate of the first fan (42) is not maximum, noise associated with the operation of the first fan (42) can be reduced.

[0100] When a predetermined time has elapsed since the start of the dissipation operation (YES in step ST38) and the discharging operation has ended in step ST39, the controller (100) sets the opening / closing mechanism (60) to the first state in step ST40. Then, the controller (100) restores the airflow rate of the first fan (42). Therefore, when the air purifier (40) is operating normally, the air in the air flow path (43) passes through the purification section (50) and is supplied to the target space (S), as shown in FIG. 7(A).

[0101] (6-3) Advantages of Modification 1 of Embodiment 2 The controller (100) reduces the flow rate of air passing through the purifying section (50) in conjunction with the dissipation operation of the dissipation unit (U2). Specifically, the controller (100) reduces the air flow rate in the first flow path (43a) and increases the air flow rate in the second flow path (43b) in conjunction with the dissipation operation. The controller (100) controls the opening / closing mechanism (60) in conjunction with the dissipation operation so that the air flow rate in the first flow path (43a) is smaller than the air flow rate in the second flow path (43b). This prevents the inhibitor from being removed by the purifying section (50) and allows the target space (S) to be sufficiently agitated by the air blown out from the air purifier (40). As a result, the inhibitor dissipation effect can be improved.

[0102] In particular, in the first modification, the controller (100) switches the opening / closing mechanism (60) serving as an adjustment unit to the second state in conjunction with the dissipation operation. As a result, the amount of air passing through the first flow path (43a) can be set to zero while ensuring a sufficient volume of blown air. This makes it possible to fully achieve the above-described effects.

[0103] The opening / closing mechanism (60) may be a damper, a shutter, a ball valve, a flow rate control valve, or the like. The flow rate adjuster may not open or close the first flow path (43a) and the second flow path (43b), but may be capable of adjusting the air flow rate of the first flow path (43a) and the air flow rate of the second flow path (43b) in multiple stages. In this case, the flow rate adjuster is also comprised of a damper, a shutter, a ball valve, a flow rate control valve, or the like.

[0104] (7) Modification 2 of Embodiment 2 As shown in Fig. 9, Modification 2 of Embodiment 2 has a first flow path (43a) and a second flow path (43b), similar to Modification 1 of Embodiment 2. The first flow path (43a) communicates with one of the inlets (41a), and the second flow path (43b) communicates with the other inlet (41a). A second fan (42A) is disposed in the first flow path (43a), and a third fan (42B) is disposed in the second flow path (43b).

[0105] During normal operation of the air purifier (40), the controller (100) operates the second fan (42A) and stops the third fan (42B).

[0106] The controller (100) controls the second fan (42A) and the third fan (42B) in conjunction with the dissipation operation so that the air flow rate in the first flow path (43a) is smaller than the air flow rate in the second flow path (43b). Specifically, the controller (100) stops the second fan (42A) and operates the third fan (42B) in conjunction with the dissipation operation. This causes the air flow rate passing through the purification section (50) of the first flow path (43a) to become zero, and allows a predetermined amount of blown air to be blown out from the air purifier (40). Therefore, the same effects as those of the first modification of the second embodiment can be obtained.

[0107] The controller (100) may operate the second fan (42A) and the third fan (42B) in conjunction with the dissipation operation, and control the second fan (42A) and the third fan (42B) so that the air flow rate in the second flow path (43b) is smaller than the air flow rate in the first flow path (43a).

[0108] (8) Modification 3 of Embodiment 2 In Modification 3 of Embodiment 2, in a configuration similar to that of the above-described Embodiment 2, the controller (100) reduces the output of the purification section (50) in conjunction with the dissipation operation of the dissipation unit (U2). Specifically, when the dissipation unit (U2) starts dissipation operation during operation of the air purifier (40), the controller (100) reduces the output of the discharge unit (52). The output here refers to a parameter that affects the air purification capacity, and includes the applied voltage for generating discharge, the power supply frequency, the voltage duty ratio, etc. In this case, the controller (100) preferably maintains the airflow rate of the first fan (42). As a result, the inhibitor in the target space (S) can be prevented from being decomposed and removed by the active species generated in the discharge unit (52).

[0109] The purifier (50) of Modification 3 may be, for example, an electrostatic precipitator unit or an ultraviolet irradiation unit. In this case, the controller (100) reduces the output of the electrostatic precipitator or the ultraviolet irradiation unit in conjunction with the dissipation operation.

[0110] The controller (100) reduces the output of the purifier (50) in conjunction with the dissipation operation of the dissipation unit (U2). When a predetermined time has elapsed since the dissipation operation of the dissipation unit, the controller (100) ends the dissipation operation and restores the output of the purifier (50) to its original state. Note that when a predetermined time has elapsed since the dissipation operation of the dissipation unit (U2), the controller (100) may also end the dissipation operation and increase the output of the purifier (50) to a predetermined output different from the original output.

[0111] (9) Third Embodiment (9-1) Configuration of Air Conditioning System The air conditioning unit (U1) of the third embodiment is a ventilation device (70) that ventilates a target space (S). As shown schematically in FIG. 10 , the ventilation device (70) is installed, for example, in the ceiling space of the target space (S). The ventilation device (70) includes a ventilation casing (71), an air supply fan (72), and an exhaust fan (73). The ventilation device (70) of this example further includes a total heat exchanger (74).

[0112] The ventilation casing (71) is formed in the shape of a hollow box. The ventilation casing (71) has an inside air inlet (71a), an exhaust port (71b), an outside air inlet (71c), and an air supply port (71d). An exhaust-side flow path (76) is formed in the ventilation casing (71) from the inside air inlet (71a) to the exhaust port (71b), and an air supply-side flow path (75) is formed in the ventilation casing (71) from the outside air inlet (71c) to the air supply port (71d).

[0113] The intake fan (72) is disposed in the intake air flow path (75), and the exhaust fan (73) is disposed in the exhaust air flow path (76). The intake air fan (72) supplies outdoor air (OA) to the indoor space (target space (S)) as supply air (SA). The exhaust fan (73) exhausts room air (RA) in the indoor space (target space (S)) to the outside of the room as exhaust air (EA). The intake air fan (72) and the exhaust fan (73) are configured to have variable rotation speeds.

[0114] The total heat exchanger (74) exchanges sensible heat and latent heat between the air in the air intake side flow path (75) and the air in the exhaust side flow path (76).

[0115] As shown in Fig. 11, the controller (100) of the third embodiment includes a diffusion control section (120) and a ventilation control section (170). The ventilation control section (170) is provided in the ventilation device (70). The ventilation control section (170) controls the ON / OFF switching of the air supply fan (72) and the exhaust fan (73) and controls the rotation speeds of the air supply fan (72) and the exhaust fan (73), in other words, the ventilation volume of the ventilation device (70).

[0116] The ventilation control unit (170) is connected to the router (130) via a wireless or wired fourth communication line (W4), and the emission control unit (120) is connected to the router (130) via a wireless or wired second communication line (W2). In this way, the ventilation control unit (170) and the emission control unit (120) are configured to be able to input a common signal.

[0117] A user can operate the ventilation device (70) and the dissipation unit (U2) by operating the communication terminal (150). The operation of the ventilation device (70) includes starting and stopping the operation of the ventilation device (70) and setting the ventilation volume of the ventilation device (70).

[0118] The ventilation device (70) has a second operating unit (175) for operating the ventilation device (70) in addition to the communication terminal (150). By operating the second operating unit (175), a user can operate the ventilation device (70) in the same way as the communication terminal (150).

[0119] (9-2) Operation (9-2-1) Operation of Ventilation Device When the ventilation device (70) is in operation, the intake fan (72) and the exhaust fan (73) are operated. The room air (RA) in the target space (S) flows into the exhaust-side flow path (76) from the room air inlet (71a). The outdoor air (OA) flows into the intake-side flow path (75) from the outdoor air inlet (21a). The total heat exchanger (74) exchanges latent heat and sensible heat between the air in the exhaust-side flow path (76) and the air in the intake-side flow path (75). The air in the exhaust-side flow path (76) is discharged to the outside of the room as exhaust air (EA). The air in the intake-side flow path (75) is supplied to the target space (S) as supply air (SA).

[0120] (9-2-2) Interlocking Control The controller (100) controls the ventilation device (70) and the dissipation unit (U2) in an interlocking manner. This interlocking control will be described with reference to Fig. 12. The following interlocking control is performed while the ventilation device (70) is in operation.

[0121] When the controller (100) receives an operation command for the dissipation operation in step ST41, the controller (100) starts the dissipation operation of the dissipation unit (U2) in step ST42. In step ST43, the controller (100) checks the set ventilation volume for the dissipation operation. Note that this set ventilation volume is input in advance to the controller (100) by the user operating the communication terminal (150) or the second operation unit (175).

[0122] If the set ventilation rate is OFF (zero) in step ST44, the process proceeds to step ST44. In step ST44, the controller (100), more precisely, the cleaning control section (160), stops the air supply fan (72) and the exhaust fan (73). As a result, the ventilation rate of the target space (S) becomes zero.

[0123] In the dissipation operation, when the ventilation device (70) operates at a predetermined ventilation rate, the inhibitors dispersed in the target space (S) are discharged to the outside of the room by ventilation. In contrast, by setting the ventilation rate to zero in conjunction with the dissipation operation, it is possible to prevent the inhibitors from being discharged to the outside of the room.

[0124] If the set ventilation volume is not OFF (zero) in step ST44, the process proceeds to step ST46. In step ST46, the controller (100), more precisely, the ventilation control unit (170), reduces the airflow rates of the air supply fan (72) and the exhaust fan (73) of the ventilation device (70) by a predetermined amount. This reduces the likelihood of the inhibitors in the target space (S) being discharged to the outside of the room. In addition, necessary ventilation can be continued in the target space (S).

[0125] When a predetermined time has elapsed since the start of the dissipation operation in step S47, the controller (100) terminates the dissipation operation of the dissipation unit (U2) in step ST48. Next, in step ST49, the controller (100), more precisely, the ventilation control section (170), restores the airflow rates of the air supply fan (72) and the exhaust fan (73) to their original airflow rates. In step ST49, the controller (100) may increase the airflow rates of the air supply fan (72) and the exhaust fan (73) to predetermined airflow rates different from the original airflow rates.

[0126] (9-3) Advantages of the Third Embodiment When the ventilation device (70) is in operation, the controller (100) reduces the airflow rate of the ventilation device (70) in conjunction with the dissipation operation of the dissipation unit (U2).

[0127] This configuration prevents the inhibitors in the target space (S) from being discharged to the outside of the room by ventilation during the dissipation operation, thereby allowing the inhibitors to fully function. In addition, it is possible to prevent the inhibitors from being collected in the total heat exchanger (74) or a filter (not shown) in the ventilation device (70), thereby preventing the life of the total heat exchanger (74) or the filter from being shortened.

[0128] In particular, in step ST45, the controller (100) stops the air supply fan (72) and the exhaust fan (73) in conjunction with the dissipation operation, thereby making it possible to fully obtain the above-described effects. Also, in step ST45, the controller (100) reduces the airflow rates of the air supply fan (72) and the exhaust fan (73) while operating the air supply fan (72) and the exhaust fan (73) in conjunction with the dissipation operation, thereby enabling continuous ventilation of the target space (S).

[0129] The controller (100) may, in conjunction with the dissipation operation, reduce the air volume of the exhaust fan (73) below the air volume of the supply fan (72). In this way, the inhibitors in the target space (S) can be agitated by the supply air (SA) while suppressing the inhibitors in the target space (S) from being discharged to the outside of the room.

[0130] (10) Other Embodiments The air conditioning system (1) may have a plurality of air conditioning units (U1). The plurality of air conditioning units (U1) may be a combination of any of the above-described air conditioners (10), air purifiers (40), and ventilation devices (70). In this case, the controller (100) executes a combination of the interlocking controls of the above-described embodiments.

[0131] The air conditioning system (1) may be a combination of the above-described air conditioning unit (U1) (first air conditioning unit) and an air conditioning unit (second air conditioning unit) having a dissipation unit (U2). In this case, the second air conditioning unit is composed of an air conditioner, air purifier, or ventilation device having a function of dissipating inhibitors.

[0132] The air conditioning system (1) may be an air conditioning / dissipation device in which the air conditioning unit (U1) and the dissipation unit (U2) are physically integrated. In this case, too, the controller (100) controls the air conditioning unit (U1) and the dissipation unit (U2) in conjunction with each other.

[0133] The air conditioning system (1) may be configured so that the air conditioning unit (U1) and the dissipation unit (U2) exchange signals with each other. In this case, for example, when the dissipation unit (U2) performs a dissipation operation, a command to start the dissipation operation is output from the dissipation unit (U2) to the air conditioning unit (U1).

[0134] The controller (100) may be provided in the server device (140) or the communication terminal (150). In this case, the server device (140) or the communication terminal (150) constitutes a control device for controlling the air conditioning unit (U1) and the dissipation unit (U2) in cooperation with each other.
