Description

Technical Field

[0001] This disclosure relates to air conditioning systems equipped with air conditioning units. Background Art

[0002] In the past, childhood asthma was a social problem, and it was established that asthma is closely related to temperature, with a high risk of attack after a sharp drop in temperature (medical books record that a temperature drop of more than 3°C within 5 hours can have negative effects on the body. Our company's research found that a temperature change of more than 3°C within 1 hour can trigger an asthma attack). Furthermore, in recent years, people have increasingly recognized air conditioners as a "health maintenance device," for example, using them as a countermeasure against heatstroke. However, on the other hand, when the set temperature deviates significantly from the temperature of the air-conditioned space, a sharp temperature change occurs, which may therefore pose a risk to asthma.

[0003] Therefore, there is a known type of air conditioner that, when the set temperature deviates significantly from the temperature of the air-conditioned space due to reasons such as misoperation of the remote control, in order to avoid the negative impact of drastic temperature changes in the air-conditioned space on the user's health, prompts the user with multiple candidate set temperatures at regular intervals after the user sets the set temperature, allowing the user to select one of them (for example, see Patent Document 1).

[0004] Patent Document 1: Japanese Patent Application Publication No. 2016-109371

[0005] In the air conditioner described in Patent Document 1, the user needs to set the set temperature and select one set temperature from multiple candidate set temperatures, which causes inconvenience to the user. Summary of the Invention

[0006] This disclosure was made to solve the above-mentioned problems, with the aim of providing an air conditioning system that reduces the inconvenience to users while suppressing drastic temperature changes.

[0007] The air conditioning system disclosed herein includes: an air conditioner for conditioning the air in a space to be conditioned; a remote operation centralized management device for communicating with the air conditioner via a network; a room temperature sensor for detecting the temperature of the space to be conditioned; and a setting unit for setting a target temperature and a target time. The remote operation centralized management device includes a control device that performs the following body load reduction control: calculating a set temperature based on the target temperature, the target time, and the temperature of the space to be conditioned, set by the setting unit for the air conditioner, in a manner that ensures the temperature change of the space to be conditioned per unit time does not exceed a preset healthy temperature gradient, and sending the set temperature to the air conditioner at preset update intervals.

[0008] According to the air conditioning system disclosed herein, since the set temperature is calculated in a manner that ensures the temperature change of the air-conditioned space per unit time does not exceed the healthy temperature gradient, and the set temperature is sent to the air conditioner for load mitigation control at every update time, it is possible to suppress drastic temperature changes while reducing the inconvenience to the user.

[0024] Hereinafter, embodiments of the present disclosure will be described based on the accompanying drawings. However, the present disclosure is not limited to the embodiments described below. Additionally, in the following drawings, the size relationships of the constituent components may sometimes differ from the actual situation.

[0025] Implementation Method 1

[0026] Figure 1 This is a schematic diagram showing the structure of the air conditioning system involved in Embodiment 1.

[0027] like Figure 1 As shown, the air conditioning system according to Embodiment 1 includes an air conditioner 1, an adapter 2, a room temperature sensor 3, a remote controller 4, a router 5, and a remote operation centralized management device 7. The air conditioner 1, adapter 2, and router 5 are installed inside the room 6. The remote operation centralized management device 7 is installed outside the room 6.

[0028] Air conditioner 1 regulates the air in the target space, room 6. Adapter 2, in addition to sending and receiving remote information different from that from remote control 4, also sends information such as the indoor unit's operating mode or set temperature. A room temperature sensor 3 is installed on air conditioner 1 to detect the temperature of room 6 (hereinafter also referred to as room temperature). Room temperature sensor 3 is, for example, a thermistor, but is not limited to this. Remote control 4 sends user-set information such as the target temperature and target time to air conditioner 1. Here, the target time refers to the time required for the room temperature to reach the target temperature. Router 5 sends and receives information via network 9 from / to adapter 2. Furthermore, although adapter 2, as... Figure 1 The device shown is located on the outside of the air conditioner 1, but it is not limited to this and can also be located inside the air conditioner 1.

[0029] The remote operation centralized management device 7 is, for example, a server, connected to the network 9. When setting operations related to instructing the air conditioner 1 are performed outside the living room 6, for example from an operating terminal 8 such as a smartphone, the setting information is temporarily sent to the remote operation centralized management device 7. Subsequently, the remote operation centralized management device 7 and the adapter 2 transmit and receive information via the network 9 and the router 5. At this time, the setting information received by the adapter 2 is sent to the air conditioner 1. In addition, besides when setting operations are performed by the remote control 4 or the operating terminal 8, the air conditioner 1 and the remote operation centralized management device 7 also conduct periodic communication to transmit and receive information between them at regular intervals. Here, the operating terminal 8 can perform setting operations related to instructing the air conditioner 1 in the same way as the remote control 4 by performing connection settings for the air conditioning system. Therefore, by performing connection settings for the air conditioning system on multiple operating terminals 8, setting operations related to instructing the air conditioner 1 can be performed from multiple operating terminals 8. Hereinafter, the remote control 4 and the operating terminal 8 will be referred to as setting units.

[0030] Figure 2 This is a functional block diagram of the air conditioner 1 of the air conditioning system involved in Implementation Method 1.

[0031] like Figure 2 As shown, the air conditioner 1 includes an air conditioner control device 10. The air conditioner control device 10 includes an input unit 11, an air conditioner indoor control unit 12, an air conditioner storage unit 13, an output unit 14, and a remote information input / output unit 15.

[0032] The air conditioner control device 10 may be composed of dedicated hardware or a CPU (Central Processing Unit, also known as a central processing unit, processing unit, arithmetic unit, microprocessor, or processor) that executes programs stored in the air conditioner storage unit 13.

[0033] When the air conditioner control device 10 is dedicated hardware, it may be equivalent to a single circuit, a composite circuit, an ASIC (Application Specific Integrated Circuit), a FPGA (Field-Programmable Gate Array), or a combination thereof. Each of the functional units implemented by the air conditioner control device 10 may be implemented by separate hardware or by a single hardware unit.

[0034] When the air conditioner control device 10 is a CPU, the various functions performed by the air conditioner control device 10 are implemented through software, firmware, or a combination of software and firmware. The software and firmware are described as programs and stored in the air conditioner storage unit 13. The CPU implements the various functions of the air conditioner control device 10 by reading and executing the programs stored in the air conditioner storage unit 13.

[0035] In addition, some functions of the air conditioner control device 10 can be implemented through dedicated hardware, and some functions can be implemented through software or firmware.

[0036] The input unit 11 processes the setting information received from the remote controller 4 or the operation terminal 8 and the temperature information obtained from the room temperature sensor 3 as input information, and then outputs it to the indoor control unit 12 of the air conditioner. The air conditioner storage unit 13 stores various information. The indoor control unit 12 uses the various information stored in the air conditioner storage unit 13 to perform calculation or judgment processing on the input information from the input unit 11, and outputs it to the output unit 14. The output unit 14 processes the processing results in the air conditioner storage unit 13 as output information and outputs it to the drive actuator 16 of the air conditioner 1. Here, the drive actuator 16 is a component of the air conditioner 1, such as a compressor, fan, and air deflector. The drive actuator 16 operates based on the output information from the output unit 14.

[0037] The remote information input / output unit 15 receives remote information, calculation results, or decision results from the remote operation centralized management device 7 via the adapter 2. Additionally, the remote information input / output unit 15 outputs information, calculation results, or decision results from the air conditioner indoor control unit 12 to the remote operation centralized management device 7 via the adapter 2.

[0038] Figure 3 This is a functional block diagram of the remote operation centralized management device 7 of the air conditioning system involved in Implementation Method 1.

[0039] like Figure 3As shown, the remote operation centralized management device 7 includes a control device 23. The control device 23 includes an air conditioner remote information input / output unit 19, a remote information control unit 20, a remote storage unit 21, and an operation terminal information processing unit 22.

[0040] When the control device 23 is dedicated hardware, the control device 23 may be equivalent to a single circuit, a composite circuit, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a combination thereof. Each of the functional units implemented by the control device 23 may be implemented by separate hardware or by a single hardware unit.

[0041] When the control device 23 is a CPU, the functions performed by the control device 23 are implemented through software, firmware, or a combination of software and firmware. The software and firmware are described as programs and stored in the remote storage unit 21. The CPU implements the functions of the control device 23 by reading and executing the programs stored in the remote storage unit 21.

[0042] In addition, some functions of the control device 23 can be implemented through dedicated hardware, and some functions can be implemented through software or firmware.

[0043] Information from air conditioner 1 is transmitted to air conditioner remote information input / output unit 19 via adapter 2, and processed by air conditioner remote information input / output unit 19 as input information. This input information is processed by remote information control unit 20, which performs calculation or judgment processing, and the processing result is stored in remote storage unit 21. In addition, the processing result is processed by air conditioner remote information input / output unit 19 as output information and transmitted to air conditioner 1 via adapter 2.

[0044] Setting information or display content requests received from the operating terminal 8 are processed as input information by the operating terminal information processing unit 22. Subsequently, information related to the display content is sent to the operating terminal 8 and displayed on its screen. Additionally, setting information is processed as output information by the air conditioner remote information input / output unit 19 and sent to the air conditioner 1 via the adapter 2.

[0045] Figure 4 This is a diagram illustrating the control flow of the remote operation centralized management device 7 of the air conditioning system involved in Embodiment 1.

[0046] Next, use Figure 4 The control flow of the remote operation centralized management device 7 for the air conditioning system according to Embodiment 1 will be explained. Furthermore, in Figure 4At the start of the control flow shown, air conditioner 1 is in a stopped state.

[0047] (Step S101)

[0048] The control device 23 acquires target temperature and target time information sent from the adapter 2 or the operating terminal 8. If the target temperature and target time are set by the user through the setting unit, the adapter 2 or the operating terminal 8 sends the target temperature and target time information to the remote operation centralized management device 7.

[0049] (Step S102)

[0050] The control device 23 acquires room temperature information sent from the adapter 2. This room temperature information is obtained from the room temperature sensor 3 and is sent by the adapter 2 to the remote operation centralized management device 7 during periodic communications.

[0051] (Step S103)

[0052] Based on the target temperature, target time, room temperature, and a preset healthy temperature gradient obtained in steps S101 and S102, control device 23 determines whether it is time to start operating the air conditioner 1. Here, the healthy temperature gradient refers to the temperature change per unit time used to determine whether it puts a burden on the human body. When the temperature change per unit time of the air-conditioned space exceeds the healthy temperature gradient, it can be determined that it puts a burden on the human body. For example, if (target time - current time) × healthy temperature gradient ≤ (current room temperature - target temperature) is true, then control device 23 determines that it is time to start operating the air conditioner 1. If control device 23 determines that it is time to start operating the air conditioner 1, the process proceeds to step S105. On the other hand, if control device 23 determines that it is not time to start operating the air conditioner 1, the process proceeds to step S104.

[0053] (Step S104)

[0054] Control device 23 determines whether the current time has reached the target time. If control device 23 determines that the current time has reached the target time, control ends. On the other hand, if control device 23 determines that the current time has not reached the target time, it returns to the processing in step S102.

[0055] (Step S105)

[0056] Control device 23 sends an operation start message to air conditioner 1. If air conditioner 1 receives the operation start message via adapter 2, air conditioner 1 starts operating. Here, the operation start message includes information about the set temperature, which is set such that the temperature change per unit time in the air-conditioned space does not exceed a value similar to a healthy temperature gradient.

[0057] (Step S106)

[0058] The control device 23 acquires room temperature information sent from the adapter 2. This room temperature information is obtained from the room temperature sensor 3 and is sent by the adapter 2 to the remote operation centralized management device 7 during periodic communications.

[0059] (Step S107)

[0060] The control device 23 determines whether the room temperature has reached the target temperature. If the control device 23 determines that the room temperature has reached the target temperature, the control ends. On the other hand, if the control device 23 determines that the room temperature has not reached the target temperature, the process proceeds to step S108.

[0061] (Step S108)

[0062] Control device 23 determines whether an update time has elapsed since the last time the set temperature information was sent to air conditioner 1. Here, the update time is, for example, [(60 / healthy temperature gradient) × minimum unit of set temperature] minutes. Therefore, with a healthy temperature gradient of 3℃ / h (3℃ per hour) and a minimum unit of set temperature of 0.5℃, the update time becomes (60 / 3) × 0.5 = 10 minutes. If control device 23 determines that an update time has elapsed since the last time the set temperature information was sent to air conditioner 1, it proceeds to step S109. On the other hand, if control device 23 determines that no update time has elapsed since the last time the set temperature information was sent to air conditioner 1, it proceeds to step S110.

[0063] (Step S109)

[0064] Control device 23 sends information about the (next) set temperature to air conditioner 1. At this time, the temperature that is closest to the target temperature by the smallest unit from the current set temperature is set as the (next) set temperature. For example, if the target temperature is 25°C, the current set temperature is 27°C, and the smallest unit of set temperature is 0.5°C, the (next) set temperature is 26.5°C. However, the temperature change per unit time of the air-conditioned space for which the set temperature is set does not exceed a value similar to a healthy temperature gradient.

[0065] (Step S110)

[0066] Control device 23 determines whether the current time has reached the target time. If control device 23 determines that the current time has reached the target time, control ends. On the other hand, if control device 23 determines that the current time has not reached the target time, it returns to the processing in step S106.

[0067] In addition, Figure 4 In the control shown, the control device 23 sends elapsed information to each operating terminal 8 that has been configured to connect to the air conditioning system, and displays it on the display screen of each operating terminal 8. Here, elapsed information refers to the temperature of the air-conditioned space relative to the elapsed time from the reference time, representing the temperature change of the air-conditioned space from the reference time to the elapsed time. The reference time can be, for example, the time when the user sets the target temperature and target time, or the time when the air conditioner 1 starts operating. By displaying elapsed information on the display screen of the operating terminal 8, the temperature of the air-conditioned space can be checked and managed even when the user is not in the air-conditioned space.

[0068] Furthermore, although the above explanation is in Figure 4 The control flow shown begins when the air conditioner 1 is in a stopped state, but when the air conditioner 1 is in an operating state, it is the same except that the processing of step S103 is skipped.

[0069] Figure 5 This is a time-varying graph showing the changes in room temperature and set temperature during the control of the air conditioning system involved in Embodiment 1.

[0070] For example, if the user wants the air-conditioned space to reach 25°C at 6 AM before going to bed, they use the setting unit to set "target temperature: 25°C" and "target time: 6 AM". The control unit 23 determines whether it's time to start the air conditioner 1 based on the target temperature, target time, and the room temperature data sent during periodic communications. With the healthy temperature gradient set to 3°C / h (3°C per hour), the control unit 23 starts cooling operation when the room temperature reaches 28°C at 5 AM. If the minimum set temperature unit is 0.5°C, the set temperature is initially set to 27.5°C (0.5°C lower than the room temperature), and then lowered by 0.5°C every 10 minutes. This avoids drastic temperature changes and ensures the room reaches the target temperature. Figure 5 The value in the figure represents the change between the current room temperature and the set temperature.

[0071] In addition, if Figure 4 As shown in the control, when the air conditioning is controlled in a way that reduces the burden on the human body, it is conceivable that the room temperature cannot reach the target temperature until the target time. In this case, any one of the following human load priority control, time priority control, and selective control is performed.

[0072] Human body load priority control is as follows: Perform Figure 4The control shown sets the set temperature to a value such that the temperature change per unit time of the air-conditioned object space does not exceed the healthy temperature gradient until the target time is reached. If the target time is reached, the target temperature is set to the set temperature.

[0073] Time priority control is as follows: In Figure 4 In the control shown, the value of the healthy temperature gradient is changed in a way that can reach the target temperature at the target time and minimize the burden on the human body.

[0074] In the selection control, when the user sets the target temperature and target time from the setting unit, the setting unit reports a message such as "The target temperature cannot be reached until the target time. Proceed?". Then, if the user inputs "Yes" from the setting unit, the process proceeds directly. Figure 4 The control shown is the same as the human body load priority control. On the other hand, if the user inputs "No" from the setting unit, the temperature shift over time is calculated to achieve the target temperature at the target time while minimizing the burden on the human body, and the setting unit reports "temperature shift over time" and "Should we proceed with this temperature shift?". Then, if the user inputs "Yes" from the setting unit, the process proceeds... Figure 4 The control shown is used to calculate the temperature shift relative to the elapsed time. This control is the same as time-priority control. On the other hand, if the user inputs "No" from the setting unit, the setting unit will report a message such as "Please set the target temperature and target time again".

[0075] Furthermore, although the above description describes the case where a specific time is set for the target time in the control flow of the remote operation centralized management device 7, it is also possible to configure the target time to be set to "not set" via the setting unit. Moreover, when the target time is set to "not set", the control flow of the remote operation centralized management device 7 is as follows.

[0076] Figure 6 This is a diagram illustrating the control flow of a remote operation centralized management device 7 based on a modified example of the air conditioning system according to Embodiment 1.

[0077] Next, use Figure 6 The control flow of the remote operation centralized management device 7 based on a variation of the air conditioning system according to Embodiment 1 will be described. Specifically, in... Figure 6 At the start of the control flow shown, air conditioner 1 is in a stopped state.

[0078] (Step S101a)

[0079] The control device 23 acquires target temperature and target time information sent from the adapter 2 or the operating terminal 8. If the target temperature and target time are set by the user through the setting unit, the adapter 2 or the operating terminal 8 sends the target temperature and target time information to the remote operation centralized management device 7.

[0080] (Step S102a)

[0081] The control device 23 acquires room temperature information sent from the adapter 2. This room temperature information is obtained from the room temperature sensor 3 and is sent by the adapter 2 to the remote operation centralized management device 7 during periodic communications.

[0082] (Step S103a)

[0083] The control device 23 determines whether it is time to start operating the air conditioner 1. However, in a variation of the air conditioning system according to Embodiment 1, since the target time is set to "not set", if a target temperature is input through the setting unit, for example, the control device 23 determines that it is time to start operating the air conditioner 1. Alternatively, the control device 23 displays the temperature shift relative to the elapsed time, the start button, and the cancel button on the display screen of the setting unit. If the user presses the start button, it is determined that it is time to start operating the air conditioner 1. If the control device 23 determines that it is time to start operating the air conditioner 1, the process proceeds to step S104a. On the other hand, if the control device 23 determines that it is not time to start operating the air conditioner 1, the process returns to step S101a.

[0084] (Step S104a)

[0085] Control device 23 sends an operation start message to air conditioner 1. If air conditioner 1 receives the operation start message via adapter 2, air conditioner 1 starts operating. Here, the operation start message includes information about the set temperature, and the temperature change per unit time of the air-conditioned space at that set temperature does not exceed a value similar to a healthy temperature gradient.

[0086] (Step S105a)

[0087] The control device 23 acquires room temperature information sent from the adapter 2. This room temperature information is obtained from the room temperature sensor 3 and is sent by the adapter 2 to the remote operation centralized management device 7 during periodic communications.

[0088] (Step S106a)

[0089] The control device 23 determines whether the room temperature has reached the target temperature. If the control device 23 determines that the room temperature has reached the target temperature, the control ends. On the other hand, if the control device 23 determines that the room temperature has not reached the target temperature, the process proceeds to step S107a.

[0090] (Step S107a)

[0091] Control device 23 determines whether an update time has elapsed since the last time the set temperature information was sent to air conditioner 1. Here, the update time is, for example, [(60 / healthy temperature gradient) × minimum unit of set temperature] minutes. Therefore, with a healthy temperature gradient of 3℃ / h (3℃ per hour) and a minimum unit of set temperature of 0.5℃, the update time becomes (60 / 3) × 0.5 = 10 minutes. If control device 23 determines that an update time has elapsed since the last time the set temperature information was sent to air conditioner 1, it proceeds to step S108a. On the other hand, if control device 23 determines that no update time has elapsed since the last time the set temperature information was sent to air conditioner 1, it returns to step S105a.

[0092] (Step S108a)

[0093] Control device 23 sends information about the (next) set temperature to air conditioner 1. At this time, the temperature that is closest to the target temperature by the smallest unit from the current set temperature is set as the (next) set temperature. For example, if the target temperature is 25°C, the current set temperature is 27°C, and the smallest unit of set temperature is 0.5°C, the (next) set temperature is 26.5°C. However, the temperature change per unit time of the air-conditioned space for which the set temperature is set does not exceed a value similar to a healthy temperature gradient.

[0094] As described above, when the target time is set to "not set", the control device 23 performs control to set a value such that the temperature change of the air-conditioned object space per unit time does not exceed the healthy temperature gradient until the target temperature is reached.

[0095] The air conditioning system according to Embodiment 1 includes: an air conditioner 1 for conditioning the air in the target space; a remote operation centralized management device 7 for communicating with the air conditioner 1 via a network 9; a room temperature sensor 3 for detecting the temperature of the target space; and a setting unit for setting a target temperature and a target time. The remote operation centralized management device 7 includes a control device 23, which performs the following body load reduction control: calculating the set temperature based on the target temperature, target time, and temperature of the target space set by the setting unit for the air conditioner 1, in a manner that the temperature change of the target space per unit time does not exceed a preset healthy temperature gradient, and sending the set temperature to the air conditioner 1 every preset update time.

[0096] According to the air conditioning system of Embodiment 1, the set temperature is calculated in such a way that the temperature change of the air-conditioned space per unit time does not exceed the healthy temperature gradient, and the body load reduction control of the set temperature is sent to the air conditioner 1 every update time. Therefore, while suppressing drastic temperature changes, it can reduce the trouble for users who have to set the set temperature and select a set temperature from multiple set temperature candidates.

[0097] In addition, in the air conditioning system according to Embodiment 1, the setting unit has a display screen. During the period of performing body load reduction control, the control device 23 sends information indicating the temperature change of the air-conditioned space to the setting unit. If the setting unit receives the information, it displays the information on the display screen.

[0098] According to the air conditioning system of Embodiment 1, since information indicating temperature changes in the air-conditioned space is displayed on the display screen of the operation terminal 8, the user can check the temperature even when not in the air-conditioned space and manage the temperature of the air-conditioned space.

[0099] Implementation Method 2

[0100] Hereinafter, Embodiment 2 will be described, but the description of the parts that are the same as those in Embodiment 1 will be omitted, and the same reference numerals will be used for the parts that are the same as or equivalent to those in Embodiment 1.

[0101] In Implementation 1, air conditioning control was implemented to reduce the burden on the human body, thus the time to reach the target temperature was slow. Since there is also a background where users use air conditioner 1 as a countermeasure against heatstroke, Implementation 2 incorporates control measures to address heatstroke. In Implementation 2, a threshold is set, and normal air conditioning control (hereinafter referred to as normal control) is performed until the room temperature falls below the threshold. If the room temperature falls below the threshold, the same control as in Implementation 1 (i.e., body load reduction control) is performed.

[0102] Figure 7 This is a diagram illustrating the control flow of the remote operation centralized management device 7 of the air conditioning system involved in Embodiment 2.

[0103] Below, use Figure 7 The control flow of the remote operation centralized management device 7 for the air conditioning system according to Embodiment 2 will be explained. Furthermore, in Figure 7 At the start of the control flow shown, air conditioner 1 is in a stopped state.

[0104] (Step S201)

[0105] The control device 23 acquires target temperature and target time information sent from the adapter 2 or the operating terminal 8. If the target temperature and target time are set by the user through the setting unit, the adapter 2 or the operating terminal 8 sends the target temperature and target time information to the remote operation centralized management device 7.

[0106] (Step S202)

[0107] The control device 23 acquires room temperature information sent from the adapter 2. This room temperature information is obtained from the room temperature sensor 3 and is sent by the adapter 2 to the remote operation centralized management device 7 during periodic communications.

[0108] (Step S203)

[0109] The control device 23 determines whether the room temperature is below a preset threshold. The threshold is set to a temperature that would be too high for the human body. That is, it determines whether the room temperature is too high for the human body. If the control device 23 determines that the room temperature is below the threshold, it proceeds to step S205. Conversely, if the control device 23 determines that the room temperature is above the threshold, it proceeds to step S204. Furthermore, in embodiment 2, this determination in step S203 is performed immediately when the user sets the target temperature and target time, but it is not limited to this. For example, it can be performed a preset time (e.g., 1 hour) earlier than the target time, or when the air conditioner 1 is equipped with a human sensor, it can be performed when the human sensor detects a person in the room 6.

[0110] (Step S204)

[0111] The control device 23 sends an operation start message to the air conditioner 1. If the air conditioner 1 receives the operation start message via the adapter 2, the air conditioner 1 starts operating. Here, the operation start message includes information about the set temperature, and a target temperature is set for that set temperature.

[0112] (Step S205)

[0113] Based on the target temperature, target time, room temperature, and a preset healthy temperature gradient obtained in steps S201 and S202, control device 23 determines whether it is time to start operating the air conditioner 1. For example, if (target time - current time) × healthy temperature gradient ≤ (room temperature - target temperature) is true, then control device 23 determines that it is time to start operating the air conditioner 1. If control device 23 determines that it is time to start operating the air conditioner 1, the process proceeds to step S207. On the other hand, if control device 23 determines that it is not time to start operating the air conditioner 1, the process proceeds to step S206.

[0114] (Step S206)

[0115] Control device 23 determines whether the current time has reached the target time. If control device 23 determines that the current time has reached the target time, control ends. On the other hand, if control device 23 determines that the current time has not reached the target time, it returns to the processing in step S202.

[0116] Furthermore, since the processing of steps S207 to S212 is the same as that of steps S105 to S110 in Embodiment 1, the explanation is omitted.

[0117] For example, in cases where "temperature that puts a burden on the human body is above 28°C", "target temperature is 26°C", or "room temperature is 32°C", the control device 23 sets the target temperature of 26°C as the set temperature and sends the set temperature information to the air conditioner 1, causing the air conditioner 1 to operate in cooling mode with 26°C as the set temperature. Furthermore, if the room temperature becomes below 28°C, the body load reduction control described in Embodiment 1 is performed to bring the room temperature to 26°C.

[0118] In addition, although Figure 7 The process is not shown in the diagram, but it can also be controlled as follows: if the room temperature becomes above the threshold during the processing of steps S207 to S212, the processing of steps S201 to S204 is performed; if the room temperature is below the threshold, the processing of steps S207 to S212 is restarted.

[0119] Additionally, although the above explanation is in Figure 7 The control flow shown begins when the air conditioner 1 is in a stopped state, but when the air conditioner 1 is in an operating state, it is the same except that the processing of step S205 is skipped.

[0120] In the air conditioning system described in Embodiment 2, when a target temperature and a target time are set for the air conditioner 1 from the setting unit, the control device 23 performs normal control by sending the target temperature to the air conditioner 1 as the set temperature when the temperature of the air-conditioned space is above a preset threshold, and performs body load reduction control when the temperature of the air-conditioned space is below the threshold.

[0121] According to the air conditioning system of Embodiment 2, normal control is performed when the temperature of the air-conditioned space is above a threshold, and body load reduction control is performed when the temperature of the air-conditioned space is below the threshold. Therefore, it is possible to suppress drastic temperature changes while speeding up the time to reach the target temperature.

[0122] Implementation Method 3

[0123] Hereinafter, Embodiment 3 will be described, but the description of the parts that are the same as those in Embodiment 1 will be omitted, and the same reference numerals will be used for the parts that are the same as or equivalent to those in Embodiment 1.

[0124] The body load reduction control in Implementation 1 takes a longer time to reach a comfortable temperature in the air-conditioned space compared to normal control. Furthermore, body load reduction control offers no advantage when the air-conditioned space is empty. Therefore, in Implementation 3, normal control and body load reduction control are used differently depending on whether a person is present. Specifically, in Implementation 3, normal control is performed when the air-conditioned space is empty, and body load reduction control is performed after a person enters the air-conditioned space.

[0125] Figure 8 This is a schematic diagram showing the structure of the air conditioning system involved in Embodiment 3. Figure 9 This is a functional block diagram of the air conditioner 1 of the air conditioning system involved in Implementation Method 3.

[0126] like Figure 8 As shown, the air conditioner 1 is equipped with a human detection sensor 201 that detects people in the room 6. Furthermore, as... Figure 9 As shown, the information on the presence or absence of a person in the room 6 obtained by the human sensor 201 is sent to the input unit 11, where it is processed as input information. The human sensor 201 can be, for example, an infrared sensor or a visual camera, but is not limited to these; any device capable of detecting the presence or absence of a person can be used.

[0127] Figure 10 This is a diagram illustrating the control flow of the remote operation centralized management device 7 of the air conditioning system involved in Embodiment 3.

[0128] Below, use Figure 10The control flow of the remote operation centralized management device 7 for the air conditioning system according to Embodiment 3 will be explained. Furthermore, in Figure 10 At the start of the control flow shown, air conditioner 1 is in a stopped state. Additionally, in Figure 10 The control flow shown begins when room 6 is empty. For example, if room 6 is set as a bedroom, a target temperature and time are set to cool the bedroom before bedtime, but the user does not enter the bedroom even when the start time for operation begins.

[0129] Since the processing of steps S301 to S307 is the same as that of steps S101 to S107 in Embodiment 1, the explanation is omitted.

[0130] (Step S308)

[0131] The control device 23 obtains information about the presence or absence of people in room 6 from the adapter 2. This information is obtained from the human presence sensor 201 and is sent by the adapter 2 to the remote operation centralized management device 7 during periodic communications.

[0132] (Step S309)

[0133] Control device 23 determines whether there is anyone in room 6. If control device 23 determines that there is someone in room 6, the process proceeds to step S311. On the other hand, if control device 23 determines that there is no one in room 6, the process proceeds to step S310.

[0134] (Step S310)

[0135] The control device 23 sets the target temperature to the set temperature and sends the set temperature information to the air conditioner 1.

[0136] (Step S311)

[0137] Control device 23 determines whether an update time has elapsed since the last time the set temperature information was sent to air conditioner 1. Here, the update time is, for example, [(60 / healthy temperature gradient) × minimum unit of set temperature] minutes. Therefore, with a healthy temperature gradient of 3℃ / h (3℃ per hour) and a minimum unit of set temperature of 0.5℃, the update time becomes (60 / 3) × 0.5 = 10 minutes. If control device 23 determines that an update time has elapsed since the last time the set temperature information was sent to air conditioner 1, it proceeds to step S312. On the other hand, if control device 23 determines that no update time has elapsed since the last time the set temperature information was sent to air conditioner 1, it proceeds to step S313.

[0138] (Step S312)

[0139] Control device 23 sends information about the (next) set temperature to air conditioner 1. At this time, the temperature that is closest to the target temperature by the smallest unit from the current set temperature is set as the (next) set temperature. For example, if the target temperature is 25°C, the current set temperature is 27°C, and the smallest unit of set temperature is 0.5°C, the (next) set temperature is 26.5°C. However, the temperature change per unit time of the air-conditioned space for which the set temperature is set does not exceed a value similar to a healthy temperature gradient.

[0140] (Step S313)

[0141] Control device 23 determines whether the current time has reached the target time. If control device 23 determines that the current time has reached the target time, control ends. On the other hand, if control device 23 determines that the current time has not reached the target time, it returns to the processing in step S306.

[0142] For example, if the bedroom temperature is 30°C at 9 PM, and the user uses the setting unit to set the target temperature to 24°C and the target time to 11 PM for the bedroom air conditioner 1, and the user enters the bedroom at 10 PM, then according to the body load reduction control in Embodiment 1, the room temperature at 11 PM becomes 27°C. In contrast, in Embodiment 3, since no one is in the bedroom from 9 PM to 10 PM, the control is normal, so the room temperature at 10 PM is already 24°C, which is comfortable.

[0143] Furthermore, the control in Implementation 3 is particularly effective when the room temperature deviates significantly from the target temperature and the current time is close to the target time. For example, if a user sets "target temperature: 23°C" and "target time: 11 PM" at 10 PM, and the current room temperature is 30°C, even though the air conditioning time is only 1 hour, a 7°C reduction in room temperature is desired. Additionally, if the health temperature gradient is set to 3°C / h (3°C per hour), it is impossible to achieve the target room temperature by the target time. However, in the control of Implementation 3, by performing normal control during periods when no one is in the air-conditioned space, the probability of achieving the target room temperature by the target time is increased. For example, if no one is detected in the air-conditioned space during the 30 minutes from 10 PM, normal control is performed during this period, resulting in a room temperature of 25.5°C at 10:30 PM. Then, if someone is detected in the air-conditioned space, the body load reduction control of Implementation 1 is performed thereafter, thereby reducing the room temperature by 1.5°C by the target time of 11 PM. Therefore, it is possible to achieve the target room temperature by the target time.

[0144] As described above, the air conditioning system according to Embodiment 3 includes a human sensing sensor 201 that detects the presence or absence of a person in the air-conditioned space. When a target temperature and target time are set for the air conditioner 1 from the setting unit, the control device 23 performs normal control by sending the target temperature as the set temperature to the air conditioner 1 during the period when no person is detected in the air-conditioned space, and performs body load reduction control during the period when a person is detected in the air-conditioned space.

[0145] According to the air conditioning system of embodiment 3, normal control is performed when no person is detected in the air-conditioned space, and physical load reduction control is performed when a person is detected in the air-conditioned space. Therefore, it is possible to suppress rapid temperature changes while speeding up the time it takes for the air-conditioned space to reach a comfortable temperature.

[0146] Implementation Method 4

[0147] Hereinafter, Embodiment 4 will be described, but the description of the parts that are the same as those in Embodiment 1 will be omitted, and the same reference numerals will be used for the parts that are the same as or equivalent to those in Embodiment 1.

[0148] When a user moves between rooms, a large temperature difference between the room of the source of movement and the room of the destination can put a strain on the human body. Therefore, in embodiment 4, the strain on the human body is reduced by decreasing the temperature difference between the room of the source of movement and the room of the destination.

[0149] Figure 11 This is a schematic diagram showing the structure of the air conditioning system involved in Embodiment 4.

[0150] like Figure 11 As shown, in embodiment 4, there are two rooms 6 and 406. Each room 6 and 406 is equipped with an air conditioner 1 and 401, an adapter 2 and 402, a room temperature sensor 3 and 403, and a remote controller 4 and 404. Moreover, the two air conditioners 1 and 401 are connected to the remote operation centralized management device 7 via the adapter 2 and 402, the router 5, and the network 9.

[0151] Air conditioner 1 regulates the air in the target space, room 6, and air conditioner 401 regulates the air in the target space, room 406. Adapter 2 transmits and receives remote information different from that from remote controller 4, and adapter 402 transmits and receives remote information different from that from remote controller 404. Room temperature sensor 3 is installed on air conditioner 1 to detect the temperature of room 6, and room temperature sensor 403 is installed on air conditioner 401 to detect the temperature of room 406. Room temperature sensors 3 and 403 are, for example, thermistors, but are not limited to this. Remote controller 4 sends user settings to air conditioner 1, and remote controller 404 sends user settings to air conditioner 401. Router 5 transmits and receives information from / to adapters 2 and 402 via network 9. Furthermore, although adapters 2 and 402 are... Figure 11 The air conditioner is shown to be installed outside the air conditioner 1 and 401, but it is not limited to this and can also be installed inside the air conditioner 1 and 401.

[0152] Figure 12 This is a diagram illustrating the control flow of the remote operation centralized management device 7 of the air conditioning system involved in Embodiment 4.

[0153] Below, use Figure 12 The control flow of the remote operation centralized management device 7 for the air conditioning system according to Embodiment 4 will be explained. Specifically, in... Figure 12 At the start of the control flow shown, the user is in room 6, air conditioner 1 in room 6 is running, and air conditioner 401 in room 406 is stopped. Furthermore, in Figure 12 After the control flow shown begins, the user moves from room 6 to room 406.

[0154] (Step S401)

[0155] The control device 23 obtains the target temperature and target time information sent from the adapter 402 or the operating terminal 8. If the user sets the target temperature and target time for the air conditioner 401 by operating the setting unit, the adapter 402 or the operating terminal 8 sends the target temperature and target time information to the remote operation centralized management device 7.

[0156] (Step S402)

[0157] The control device 23 obtains the temperature information of the room 406 sent from the adapter 402. The temperature information of the room 406 is obtained from the room temperature sensor 403 and sent by the adapter 402 to the remote operation centralized management device 7 during periodic communication.

[0158] (Step S403)

[0159] Based on the target temperature, target time, room temperature 406, and a preset healthy temperature gradient obtained in steps S401 and S402, control device 23 determines whether it is time to start operating the air conditioner 401. For example, if (target time - current time) × healthy temperature gradient ≤ (current room temperature - target temperature), then control device 23 determines that it is time to start operating the air conditioner 401. If control device 23 determines that it is time to start operating the air conditioner 401, the process proceeds to step S405. On the other hand, if control device 23 determines that it is not time to start operating the air conditioner 401, the process proceeds to step S404.

[0160] (Step S404)

[0161] Control device 23 determines whether the current time has reached the target time. If control device 23 determines that the current time has reached the target time, control ends. On the other hand, if control device 23 determines that the current time has not reached the target time, it returns to the processing in step S402.

[0162] (Step S405)

[0163] Control device 23 determines whether there is anyone in room 6. If control device 23 determines that there is someone in room 6, the process proceeds to step S406. On the other hand, if control device 23 determines that there is no one in room 6, the process proceeds to step S408.

[0164] Furthermore, in step S405, if the air conditioner 1 is equipped with a human detection sensor, the control device 23 can determine whether there is someone in room 6 based on whether the human detection sensor detects a person in room 6, whether the air conditioner 1 is running, or whether a target temperature and target time have been set for the air conditioner 401 within a preset time after the air conditioner 1 stops. If the air conditioner 1 is running, it can be considered that someone is in room 6. Alternatively, if the air conditioner 1 is stopped when someone is about to leave the room, and a target temperature and target time have been set for the air conditioner 401 within a preset time after the air conditioner 1 stops, it can also be considered that someone is in room 6.

[0165] (Step S406)

[0166] The control device 23 acquires the temperature information of room 6 sent from the adapter 2. The temperature information of room 6 is obtained from the room temperature sensor 3 and is sent by the adapter 2 to the remote operation centralized management device 7 during periodic communication.

[0167] (Step S407)

[0168] The control device 23 sends an operation start message to the air conditioner 401. If the air conditioner 401 receives the operation start message via the adapter 402, the air conditioner 401 starts operating. Here, the operation start message includes information about the set temperature, which is used to set the room temperature of the room 6.

[0169] (Step S408)

[0170] Control device 23 sends an operation start message to air conditioner 401. If air conditioner 401 receives the operation start message via adapter 2, air conditioner 401 starts operating. Here, the operation start message includes information about the set temperature, and the temperature change per unit time of the air-conditioned space at that set temperature does not exceed a value similar to a healthy temperature gradient.

[0171] (Step S409)

[0172] The control device 23 obtains the temperature information of the room 406 sent from the adapter 402. The temperature information of the room 406 is obtained from the room temperature sensor 403 and sent by the adapter 402 to the remote operation centralized management device 7 during periodic communication.

[0173] (Step S410)

[0174] The control device 23 determines whether the temperature of room 406 has reached the target temperature. If the control device 23 determines that the temperature of room 406 has reached the target temperature, the control ends. On the other hand, if the control device 23 determines that the temperature of room 406 has not reached the target temperature, the process proceeds to step S411.

[0175] (Step S411)

[0176] Control device 23 determines whether an update time has elapsed since the last time the set temperature information was sent to air conditioner 401. Here, the update time is, for example, [(60 / healthy temperature gradient) × minimum unit of set temperature] minutes. Therefore, with a healthy temperature gradient of 3℃ / h (3℃ per hour) and a minimum unit of set temperature of 0.5℃, the update time becomes (60 / 3) × 0.5 = 10 minutes. If control device 23 determines that an update time has elapsed since the last time the set temperature information was sent to air conditioner 401, it proceeds to step S412. On the other hand, if control device 23 determines that no update time has elapsed since the last time the set temperature information was sent to air conditioner 401, it proceeds to step S413.

[0177] (Step S412)

[0178] Control device 23 sends information about the (next) set temperature to air conditioner 401. At this time, the temperature that is closest to the target temperature by the smallest unit from the current set temperature is set as the (next) set temperature. For example, if the target temperature is 25°C, the current set temperature is 27°C, and the smallest unit of set temperature is 0.5°C, the (next) set temperature is 26.5°C. However, the temperature change per unit time of the air-conditioned space for which the set temperature is set does not exceed a value similar to a healthy temperature gradient.

[0179] (Step S413)

[0180] Control device 23 determines whether the current time has reached the target time. If control device 23 determines that the current time has reached the target time, control ends. On the other hand, if control device 23 determines that the current time has not reached the target time, it returns to the processing in step S409.

[0181] For example, room 6 is designated as the living room, and room 406 as the bedroom. While the user spends time in the living room before going to bed, a target temperature and target time are set for the bedroom's air conditioner 401. At this time, with the living room at 23°C due to air conditioning and the bedroom at 28°C due to lack of air conditioning, the bedroom temperature is unlikely to drop significantly under the body load reduction control described in Embodiment 1. If the user moves to the bedroom before the target time, the burden on the body, such as sweating before bedtime, increases. Therefore, as in Embodiment 4, while the user is in the living room (the mobile source), the bedroom (the mobile destination) is kept at the same temperature as the living room. When the user moves to the bedroom, the body load reduction control described in Embodiment 1 is applied, thereby reducing the temperature difference between the mobile source room and the mobile destination room, thus reducing the burden on the body.

[0182] The air conditioning system described in Embodiment 4 includes two air conditioners 1 and 401 that respectively regulate the air of different air-conditioned spaces. When the air conditioner 1 regulating the air of one air-conditioned space is in operation and the air conditioner 401 regulating the air of the other air-conditioned space is in a stopped state, and a target temperature and target time are set for the other air conditioner 401 from the setting unit, the control device 23 performs normal control by sending the temperature of the air-conditioned space of one air-conditioned space as the set temperature to the air conditioner 401 of the other air conditioner when a person is detected in the air-conditioned space of one air conditioner. When no person is detected in the air-conditioned space of one air conditioner, the control device 23 calculates the set temperature based on the target temperature, target time, and temperature of the other air-conditioned space in a way that the temperature change of the other air-conditioned space per unit time does not exceed the healthy temperature gradient, and sends the set temperature to the air conditioner 401 of the other air conditioner for body load reduction control every update time.

[0183] According to the air conditioning system of Embodiment 4, when a person is detected in the air-conditioned object space that is the source of movement, the same temperature environment as the air-conditioned object space in the other air-conditioned object space that is the destination of movement is normally controlled. Therefore, the temperature difference between the destination and the source of movement can be reduced.

[0184] Implementation Method 5

[0185] Hereinafter, Embodiment 5 will be described, but the description of the parts that are the same as those in Embodiment 1 will be omitted, and the same reference numerals will be used for the parts that are the same as or equivalent to those in Embodiment 1.

[0186] When the air conditioner 1 is turned off in winter, it is conceivable that the temperature of the air-conditioned space may drop drastically due to the airtightness of the residence. However, since people are particularly insensitive to temperature changes while sleeping, it is difficult to notice even if a drastic temperature drop occurs in the air-conditioned space. Furthermore, the temperature of the air inhaled by the lungs is crucial to prevent asthma attacks. While sleeping, the body feels warm from being under the covers, but the temperature inhaled by the lungs is low, thus increasing the risk of asthma attacks due to temperature fluctuations. However, many users want to turn off the air conditioner 1 while sleeping to save electricity. Therefore, in Embodiment 5, when the airtightness of the residence is detected as low, even if the setting to stop is executed from the setting unit, temporary suppression of heating operation is performed to avoid drastic temperature changes in the air-conditioned space. The air conditioner 1 stops operating after the temperature difference between the air-conditioned space and the outside temperature has narrowed to a certain level, thereby reducing the burden on the human body.

[0187] Figure 13This is a schematic diagram showing the structure of the air conditioning system involved in Embodiment 5. Figure 14 This is a functional block diagram of the air conditioner 1 of the air conditioning system involved in Implementation Method 5.

[0188] like Figure 13 As shown, the air conditioner 1 includes an outdoor unit 501, and an outdoor temperature sensor 502 for detecting the outside temperature is installed on the outdoor unit 501. The outdoor temperature sensor 502 is, for example, a thermistor, but is not limited to this. Furthermore, as... Figure 14 As shown, the external temperature information obtained by the external temperature sensor 502 is sent to the input unit 11, which processes it as input information.

[0189] Figure 15 This is a diagram illustrating the control flow of the remote operation centralized management device 7 of the air conditioning system involved in Embodiment 5.

[0190] Below, use Figure 15 The control flow of the remote operation centralized management device 7 for the air conditioning system according to Embodiment 5 will be explained. Furthermore, in Figure 15 At the start of the control flow shown, air conditioner 1 is in operation.

[0191] (Step S501)

[0192] Control device 23 determines whether a stop message has been received. If the air conditioner 1 has been set to stop by the user's operation setting unit, the adapter 2 or the operation terminal 8 sends the stop message to the remote operation centralized management device 7. If control device 23 determines that a stop message has been received, it proceeds to step S502. On the other hand, if control device 23 determines that no stop message has been received, it repeats step S501.

[0193] (Step S502)

[0194] Control device 23 acquires external temperature information sent from adapter 2. This external temperature information is obtained from external temperature sensor 502 and is sent by adapter 2 to remote operation centralized management device 7 during periodic communications.

[0195] (Step S503)

[0196] The control device 23 acquires room temperature information sent from the adapter 2. This room temperature information is obtained from the room temperature sensor 3 and is sent by the adapter 2 to the remote operation centralized management device 7 during periodic communications.

[0197] (Step S504)

[0198] Based on the external air temperature, room temperature, pre-set healthy temperature gradient, and the airtightness of the residence obtained in steps S502 and S503, control device 23 determines whether it is necessary to stop heating to reduce the burden on the human body (hereinafter referred to as auxiliary heating). Here, regarding the airtightness and insulation performance of the residence, when the room temperature becomes uniform while the air conditioner 1 is running, it can be said that the heat balance of the room where the air conditioner 1 is running is balanced. Therefore, it can be inferred from the temperature difference between the room temperature and the external air temperature, and the heat input (blowing temperature and blowing air volume) of the air conditioner 1. At this time, the influence of sunlight and other heat sources such as indoor appliances can also be taken into consideration. If control device 23 determines that auxiliary heating is needed, the process proceeds to step S505. On the other hand, if control device 23 determines that auxiliary heating is not needed, the control ends. Auxiliary heating is only effective when there are people in the air-conditioned space. Therefore, the conditions for determining whether auxiliary heating is needed can include whether there are people in the air-conditioned space or the pre-learned bedtime of the users.

[0199] (Step S505)

[0200] The control device 23 calculates the set temperature based on the outside air temperature, room temperature, healthy temperature gradient, and the airtightness of the residence in a manner that does not cause temperature changes exceeding the healthy temperature gradient, and sends the set temperature information to the air conditioner 1.

[0201] In addition, in step S504, even if the control device 23 determines that auxiliary heating is required, if the user sets the air conditioner 1 to stop again, the user's intention will be respected, the auxiliary heating will be canceled and the air conditioner 1 will be stopped.

[0202] For example, if a user sets air conditioner 1 to stop before going to bed, and the outside temperature is 0°C and the room temperature is 23°C, based on the airtightness of the residence, if it is determined that there is a temperature change exceeding a healthy temperature gradient of more than 3°C / h (i.e., a temperature change exceeding 3°C per hour), auxiliary heating will be activated. This avoids drastic temperature changes during sleep. For users who are concerned about drastic temperature changes and therefore run air conditioner 1 continuously while sleeping, this reduces the operating time of air conditioner 1, thus saving electricity.

[0203] As described above, the air conditioning system according to Embodiment 5 includes an external temperature sensor 502 for detecting the external temperature. When the air conditioner 1 is in operation and the air conditioner 1 is set to stop from the setting unit, the control device 23 determines whether it is necessary to stop the system to reduce the burden on the human body based on the external temperature, the temperature of the air-conditioned space, and the airtightness of the residence. If it is determined that it is necessary to stop the system to reduce the burden on the human body, the control device 23 calculates the set temperature based on the external temperature, the temperature of the air-conditioned space, and the airtightness of the residence, and sends the set temperature to the air conditioner 1. If it is determined that it is not necessary to stop the system to reduce the burden on the human body, the control device 23 sends a stop message to the air conditioner 1.

[0204] According to the air conditioning system of embodiment 5, when it is determined that it is necessary to stop the operation to reduce the burden on the human body, the set temperature is calculated based on the outside temperature, the temperature of the air-conditioned space, and the airtightness of the residence, and the set temperature is sent to the air conditioner 1. Therefore, it is possible to avoid drastic temperature changes in the air-conditioned space after the air conditioner 1 stops.
