Description

The present invention relates to an air conditioner.

The air conditioner is equipped with electric motors such as a compressor, an indoor fan, and an outdoor fan. For example, if a disaster such as an earthquake occurs and an electric leakage or short circuit occurs in these devices, there is a risk of electric shock or fire. Therefore, an air conditioning system has been proposed in which an actuator such as a compressor is stopped when disaster information such as an earthquake early warning is received to suppress a secondary disaster (see, for example, Japanese Patent Application Laid-Open No. 2011-202832). This makes it possible to stop the air conditioning system before a disaster occurs and prevent accidents in the air conditioning system.

Japanese Unexamined Patent Publication No. 2011-202832

However, in the air conditioning system of JP2011-202832, it is possible to start the operation of the air conditioning system regardless of the presence or absence of an abnormality after stopping the air conditioning system due to a disaster, due to electric leakage or short circuit. There is a risk of a secondary disaster. Further, in the air conditioning system, at the user's discretion, the air conditioning system can be prevented from operating to prevent the occurrence of a secondary disaster, but the room cannot be kept comfortable unless the air conditioning system is operated. ..

Therefore, an object of the present invention is to provide an air conditioner capable of maintaining a comfortable temperature in a living room and suppressing secondary damage caused by operating an air conditioner in which an abnormality has occurred due to a disaster. ..

In order to achieve the above object, the air conditioner of the present invention outputs a notification sound to the heat pump that exchanges heat between the living room and the outside of the living room, a communication unit that communicates with the outside, and the living room. A notification sound output unit, a control unit, and at least the heat pump, the communication unit, the notification sound output unit, and a power supply unit for supplying electric power to the control unit are provided, and the control unit is provided via the communication unit. When the disaster information is received, the power supply from the power supply unit to other than the control unit is stopped after the disaster information is output as a notification sound from the notification sound output unit, and after a predetermined time has elapsed from the reception of the disaster report. , Initial diagnosis to confirm the energization state from the power supply unit, and drive diagnosis to confirm the abnormality during driving by continuously operating the heat pump for a certain period of time when no abnormality is confirmed in the initial diagnosis. When an abnormality is confirmed in the initial diagnosis or the drive diagnosis, the control unit stops the power supply from the power supply unit to other than the control unit.

According to this configuration, since the notification of disaster information is notified by voice using the notification speaker, it is possible to quickly inform the person in the living room of the occurrence (possibility of occurrence) of the disaster. Further, when the air conditioner receives the disaster information (here, the earthquake early warning is received), the power supply is temporarily stopped and the air conditioner is stopped. Then, after the earthquake or the like has subsided, the presence or absence of an abnormality in the air conditioner and the location of the abnormality when there is an abnormality are identified. Then, when there is an abnormality, do not drive. As a result, it is possible to suppress the occurrence of secondary disasters such as electric shock due to electric leakage and fire due to short circuit.

The above-mentioned air conditioner is further provided with a temperature detection unit that detects the temperature in the living room, and when the heat pump is in a non-operating state when the disaster information is received, the control unit is abnormal in the initial diagnosis. The heat pump may be operated in an appropriate operating state based on the temperature in the living room detected by the temperature detection unit to perform a drive diagnosis.

According to this configuration, since the operation of the heat pump is determined so that the amount of heat exchanged inside and outside the living room is large, a temperature difference in the refrigerant piping is likely to occur, and the temperature difference is likely to be large. This makes it easy to detect abnormalities in the heat pump due to temperature during drive diagnosis.

In the above-mentioned air conditioner, the control unit stores the operating state of the heat pump when the disaster information is received, and receives the disaster information from the heat pump when no abnormality is confirmed in the initial diagnosis. It may be operated in the operating state at the time to perform a drive diagnosis.

According to this configuration, in order to make the living room comfortable, it is operated under the same conditions as the heat pump that exchanged heat. Since the operation of the heat pump is determined, a temperature difference in the refrigerant piping is likely to occur, and the temperature difference is likely to be large. This makes it easy to detect abnormalities in the heat pump due to temperature during drive diagnosis.

In the above configuration, after the drive diagnosis determines that there is no abnormality, the control unit may put the heat pump into the operating state when the disaster information is received.

According to this configuration, the time during which the air conditioner is stopped can be shortened. As a result, it is possible to suppress a decrease in the comfort of the living room.

In the above configuration, the control unit may notify an external device of the diagnosis result by using the communication unit after the initial diagnosis or the drive diagnosis is completed.

In the above configuration, the external device may be a server that is connected via the Internet and stores abnormal information.

In the above configuration, a remote controller that is arranged in the living room and for performing operation input is further provided, and the control unit is performing the initial diagnosis at least until a predetermined time elapses from the reception of the disaster report. And after the abnormality is confirmed, the operation input from the remote controller may not be accepted.

According to this configuration, even if the remote controller is accidentally operated while the diagnosis of the air conditioner is not completed or when there is an abnormality in the air conditioner, the air conditioner does not operate. Therefore, even if there is an abnormality, the operation can be started and the electric shock due to the electric leakage and the ignition due to the short circuit can be suppressed.

According to the present invention, it is possible to provide an air conditioner capable of maintaining a comfortable temperature in a living room and suppressing secondary damage caused by operating an air conditioner in which an abnormality has occurred due to a disaster.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First Embodiment)
FIG. 1 is a schematic view of a living room provided with an air conditioner according to the present invention. As shown in FIG. 1, the air conditioner A has an indoor unit IM installed inside the living room Rm and an outdoor unit OM installed outside the living room Rm. As shown in FIG. 1, the living room Rm is a space surrounded by a ceiling CL, a floor FL, and four wall BWs. The indoor unit IM is attached to one of the wall BWs. In the actual living room Rm, the wall BW, ceiling CL, etc. may be provided with openings such as doors and windows, but these openings are closed when air conditioning is performed, and the wall BW, ceiling CL, etc. It is omitted because it can be considered as one. The air conditioner A takes in the air in the living room Rm into the indoor unit IM and discharges the harmonious air to perform air conditioning (cooling, heating, air purification) in the living room Rm.

Next, the details of the air conditioner A according to the present invention will be described with reference to the drawings. FIG. 2 is a block diagram showing a schematic configuration of an air conditioner according to the present invention, and FIG. 3 is a schematic diagram of a heat pump of the air conditioner shown in FIG.

As shown in FIG. 2, the air conditioner A includes a control unit 1, a heat pump 2, a storage unit 3, a notification speaker 4 (notification sound output unit), a communication unit 5, a remote control communication unit 6 (remote controller communication unit), and a remote controller. 7 (remote controller) and power supply unit 8 are provided.

The control unit 1 controls the operation of each unit constituting the air conditioner A. The control unit 1 includes, for example, a processing circuit such as a CPU. The control unit 1 is arranged in the indoor unit IM. The control unit 1 changes the air conditioning conditions such as temperature, humidity, air volume, and wind direction, and harmonizes the air in the living room Rm. In addition to these, control processing of each part of the air conditioner A is performed. A living room temperature sensor S1 is connected to the control unit 1. The living room temperature sensor S1 is a sensor that measures the temperature inside the living room Rm. The living room temperature sensor S1 measures the temperature in the living room Rm periodically or in response to control from the control unit 1, and sends the information to the control unit 1.

As shown in FIGS. 2 and 3, the heat pump 2 includes a compressor 21, a four-way valve 22, an outdoor heat exchanger 23, a decompression unit 24, an indoor heat exchanger 25, an outdoor fan 26, and an indoor fan 27. Then, the compressor 21, the four-way valve 22, the outdoor heat exchanger 23, the decompression unit 24, and the indoor heat exchanger 25 are connected by a refrigerant pipe, and a refrigerant circuit in which the refrigerant is sealed is configured.

The decompression unit 24, the indoor heat exchanger 25, and the indoor fan 27 are arranged in the indoor unit IM. Further, the compressor 21, the four-way valve 22, the outdoor heat exchanger 23, and the outdoor fan 26 are arranged in the outdoor unit OM. The compressor 21, the four-way valve 22, the outdoor fan 26, and the indoor fan 27 are connected to the control unit 1. The decompression unit 24 may be provided in the outdoor unit OM instead of the indoor unit.

The compressor 21 is a device that compresses the refrigerant, and it is possible to change the air conditioning conditions (temperature, humidity) by controlling the operation (for example, the number of rotations) of the compressor 21. The four-way valve 22 changes the flow direction of the refrigerant circuit. By switching the direction in which the refrigerant flows with the four-way valve 22, the heat pump 2 switches to a cooling operation for cooling the living room or a heating operation for warming the living room. The pressure reducing unit 24 reduces the pressure of the refrigerant, and for example, a capillary tube, an expansion valve, or the like is adopted.

The outdoor heat exchanger 23 and the indoor heat exchanger 25 are for exchanging heat between the air inside and outside the living room Rm and the refrigerant, respectively. For example, fins for increasing the cross-sectional area of the refrigerant pipe. Can be mentioned. It is possible to improve the efficiency of heat exchange by blowing air onto the fins and forcibly sending air. Therefore, in the heat pump 2, an outdoor fan 26 is provided in the vicinity of the outdoor heat exchanger 23, and an indoor fan 27 is provided in the vicinity of the indoor heat exchanger 25.

Further, the heat pump 2 is provided with a temperature measuring unit 28 for measuring the temperature of a pipe (referred to as a refrigerant pipe) through which the refrigerant flows. The temperature measuring unit 28 is connected to the control unit 1 and transmits the measured temperature of the refrigerant pipe to the control unit 1. For example, the temperature measuring unit 28 measures the temperature of the pipe connected to the discharge side of the compressor 21 and also measures the temperature of the return pipe to the compressor 21. When the refrigerant is compressed by the compressor 21, the pressure is increasing and the temperature is high. On the other hand, the refrigerant that exchanges heat between the outdoor heat exchanger 23 and the indoor heat exchanger 25 and returns from the compressor 21 has a lower temperature than that on the discharge side. That is, in the heat pump 2, a temperature difference occurs between the discharge side pipe and the return pipe during the operation of the compressor 21. If this temperature difference does not occur, it can be determined that there is a high possibility that the heat pump 2 is abnormal, for example, the refrigerant is leaking. In the air conditioner A according to the present embodiment, the temperature measuring unit 28 measures the temperature of the discharge side pipe and the return pipe of the compressor 21, but the temperature is not limited to this. When the refrigerant leaks, the temperature of the pipe whose temperature changes as compared with the normal operation may be measured.

The storage unit 3 stores information and programs necessary for the control unit 1 to perform various processes. The storage unit 3 includes a ROM (Read Only Memory) capable of reading only information, a RAM (Random Access Memory) capable of accessing (reading and writing) information at any time, and the like.

The remote control communication unit 6 and the remote control 7 perform wireless communication. In the air conditioner A, the remote controller communication unit 6 and the remote controller 7 perform communication using infrared rays. The remote control communication unit 6 receives an infrared signal from the remote control 7 and transmits the signal to the control unit 1. The remote controller 7 operates the air conditioner A from a remote location. The remote controller 7 includes a display unit 71 and an operation unit 72. The display unit 71 displays various information. As the information to be displayed on the display unit 71, for example, the current time and the operating state (cooling, heating, ventilation, dryness, etc.) can be mentioned.

When the remote controller 6 and the remote controller 7 are capable of bidirectional communication, information transmitted from the remote controller 6 such as the temperature inside and outside the living room, the continuous operation time of the air conditioner A, the filter maintenance instruction, and the like. It is also possible to display information. In the air conditioner A of the present embodiment, the remote controller communication unit 6 and the remote controller 7 are capable of bidirectional communication. The operation unit 72 includes, for example, an input device such as a hard key. Further, the operation unit 72 may be provided with a touch input device, that is, a so-called touch panel, which detects that the operation image displayed on the display unit 71 is touched and outputs an operation signal corresponding to the operation image.

Further, the communication between the remote control communication unit 6 and the remote control 7 employs infrared communication using infrared light, but the communication is not limited to this. For example, a radio wave having a specific frequency may be used. A device that can accurately communicate with the remote controller 6 and the remote controller 7 can be widely adopted.

The communication unit 5 is connected to a wireless and / or wired network. For example, the communication unit 5 is connected to a small-scale communication network constructed in a building including a living room Rm. As a small-scale communication network, at least one of wired and wireless is constructed. It may be a network that can be connected by both. For example, terminals such as smartphones and tablet PCs, home security systems, home energy management systems (HEMS), and the like are connected to the small-scale communication network. The air conditioner A can notify the above-mentioned terminal or system of information from the communication unit 5 or vice versa.

In addition, the small-scale communication network is connected to an external network such as the Internet or a telephone line. As a result, the communication unit 5 can send and receive information to and from a device connected to an external network via a small-scale communication network. The communication unit 5 may be directly connected to an external communication network such as the Internet or a telephone line (in FIG. 2, it is simply displayed as a communication network). At this time, the communication unit 5 may or may not be connected to the small-scale communication network. In the air conditioner A according to the present embodiment, disaster information (for example, an earthquake early warning) is notified from a disaster information notification server (not shown) provided on the Internet. The details of the disaster information and the notification of the disaster information will be described later.

The communication unit 5 is connected to the control unit 1, and when the communication unit 5 receives the disaster information, the communication unit 5 transmits the contents of the received disaster information to the control unit 1. The communication unit 5 provides disaster information regardless of whether the air conditioner A is performing air conditioning (hereinafter referred to as an operating state) or not performing air conditioning (hereinafter referred to as a stopped state). Receive. Further, when the communication unit 5 receives the disaster information, the control unit 1 may be set to return from the standby state, and the control unit 1 may be always ON as in the communication unit 5. .. In the air conditioner A of the present embodiment, when the air conditioner A is stopped, the control unit 1 is in the standby state, and when the communication unit 5 receives the disaster information, it is assumed to return from the standby state.

The notification speaker 4 is a notification sound output unit that outputs a notification sound from the air conditioner A. Examples of the notification sound include voices such as an alarm sound, disaster information received by the communication unit 5, and information such as temperature and humidity of the living room Rm. In addition, the current time and the current operating status (cooling, heating, continuous operation time, etc.) may be included. The notification speaker 4 is connected to the control unit 1 and outputs a notification sound according to an instruction from the control unit 1. The notification sound output unit may include a notification speaker 4 and a notification sound generation circuit that generates a notification sound output by the notification speaker.

The power supply unit 8 supplies the electricity supplied from the commercial power system to each part of the air conditioner A at an appropriate voltage and / or current. The electricity supply source is not limited to the commercial power system, but may be a power source such as a storage battery or a generator.

The power supply unit 8 includes an AC / DC converter, a DC / DC converter, and the like. Further, the power supply unit 8 adjusts the outputs of the compressor 21, the outdoor fan 26, and the indoor fan 27 by adjusting the electric currents supplied to the compressor 21, the outdoor fan 26, and the indoor fan 27. Further, the power supply unit 8 supplies electricity for operation to the control unit 1, the storage unit 3, the notification speaker 4, the communication unit 5, and the remote control communication unit 6. The voltage and current supplied to the control unit 1, the storage unit 3, the notification speaker 4, the communication unit 5, and the remote control communication unit 6 are constant. The power supply unit 8 adjusts the electricity supplied to each unit based on the instruction from the control unit 1. In addition to the power supply unit 8, the control unit 1 may include a backup power source such as a storage battery so that electricity can be supplied even if the power supply is stopped due to a power failure or the like. The air conditioner A according to the present invention has the configuration shown above.

Next, the disaster notification will be described. For example, an earthquake includes a P wave and an S wave whose propagation speed is slower than that of the P wave. In a normal earthquake, after the P wave arrives from the epicenter and the preliminary tremors occur, the S wave arrives and a mainshock with a larger amplitude than the preliminary tremors occurs. In Japan, an Earthquake Early Warning (disaster notification) is sent immediately after the preliminary tremors are observed. If the living room Rm is located far from the epicenter, a delay time will occur between the reception of the Earthquake Early Warning and the occurrence of the mainshock.

Further, the earthquake may cause damage to the electric wiring of the air conditioner A (for example, the electric wiring connecting the indoor unit IM and the outdoor unit OM), an abnormality of the heat pump 2, and the like. Therefore, the air conditioner A according to the present embodiment is stopped after receiving the disaster notification (here, the Earthquake Early Warning). After that, the air conditioner A diagnoses each part before restarting the operation.

The details of the operation of the air conditioner according to the present embodiment will be described below with reference to the drawings. FIG. 4 is a flowchart showing a diagnostic operation when a disaster notification of the air conditioner according to the first embodiment is received.

The communication unit 5 is in a state in which the air conditioner A can receive the disaster information regardless of the operating state or the stopped state, and as shown in FIG. 4, waits for the reception of the disaster information (step S101). In the present embodiment, the earthquake early warning is received as disaster information, but the present invention is not limited to this. It may be a tornado warning, a lightning warning, etc. as described above, or it may be other information. Information on disasters that may cause failure or damage of the air conditioner A may be widely received.

When the communication unit 5 receives the disaster information (Yes in step S101), the control unit 1 outputs a notification sound in the living room Rm by the notification speaker 4 (step S102). Here, the notification sound includes an alarm sound such as a siren and a voice alarm.

The control unit 1 confirms whether or not the air conditioner A is in operation (step S103). That is, it is confirmed whether or not the air conditioner A is in the air conditioning of the living room Rm when the disaster information is received. When the air conditioner A is in operation (Yes in step S103), the control unit 1 issues an instruction to the power supply unit 8 to stop the power supply to other than the control unit 1, that is, air conditioner. The machine A is stopped (step S104). When the control unit 1 is provided with a backup power supply, the control unit 1 may control to stop the power supply unit 8 itself.

Then, when the air conditioner A is not in operation (No in step S103) or after the air conditioner A is stopped (after step S104), the control unit 1 waits until a predetermined time elapses. (Step S105). Here, the predetermined time is a time assumed after receiving the Earthquake Early Warning until the end of the mainshock (that is, until the arrival of the S wave is completed). The predetermined time may be a predetermined time (for example, 10 minutes, etc.), or may be determined by calculating from the location information of the epicenter and the current location. In the present embodiment, the time is set to a predetermined time. Further, the predetermined time may be changed by the user.

When the earthquake early warning is received and a predetermined time has elapsed (Yes in step S105), the control unit 1 determines that the mainshock has ended and diagnoses the presence or absence of an abnormality in each part of the air conditioner A (). Step S106). The initial diagnosis is the diagnosis of the air conditioner A that has stopped after receiving the disaster information.

Here, the initial diagnosis will be described with reference to the drawings. FIG. 5 is a flowchart showing the operation of the initial diagnosis. The initial diagnosis shown in FIG. 5 diagnoses whether or not the air conditioner A has an abnormality that interferes with operation due to a disaster (earthquake). In the air conditioner A, the compressor 21 and the outdoor fan 26 arranged in the outdoor unit OM are driven in response to the control signal from the control unit 1 arranged in the indoor unit IM. Therefore, if communication between the indoor unit IM and the outdoor unit OM is not secured, it is difficult to accurately drive the compressor 21 and the outdoor fan 26. Therefore, in the air conditioner A, first, the communication state between the indoor unit IM and the outdoor unit OM is confirmed (step S201).

The control unit 1 determines whether or not there is an abnormality in the communication state between the indoor unit IM and the outdoor unit OM from the confirmation result of the communication state between the indoor unit IM and the outdoor unit OM (step S202). When there is an abnormality in the communication state between the indoor unit IM and the outdoor unit OM (Yes in step S202), the control unit 1 records in the storage unit 3 that there is an abnormality in the communication state (step S203). , It is determined that there is an abnormality (step S217), and the initial diagnosis is completed (proceed to step S107 in FIG. 4). That is, when there is an abnormality in the communication state of the indoor unit IM and the outdoor unit OM, the control unit 1 arranged in the indoor unit IM cannot transmit the control signal to the device arranged in the outdoor unit OM. Since the control unit 1 cannot accurately control the equipment arranged in the outdoor unit OM, the control unit 1 ends the initial diagnosis without performing any other diagnosis.

If there is no abnormality in the communication between the indoor unit IM and the outdoor unit OM (No in step S202), the control unit 1 receives power from the power supply unit 8 provided in the indoor unit IM to the outdoor unit OM. (Step S204). The power supply from the power supply unit 8 to the outdoor unit OM is for confirming a short circuit, disconnection, etc. of the power wiring, and is performed in a short time. Further, when checking the power supply in case the power wiring from the power supply unit 8 to the outdoor unit OM is short-circuited or broken, when driving the compressor 21 or the outdoor fan 26. It can be performed with a voltage and current smaller than the voltage and current. Further, the confirmation of energization to each part of the heat pump 2 plays a role of confirming the continuity of the electric wiring from the power supply unit 8 to each part of the heat pump 2 as well as the state of each part.

Then, the control unit 1 confirms whether or not there is an abnormality in the power supply from the power supply unit 8 to the outdoor unit OM from the confirmation result of the power supply from the power supply unit 8 to the outdoor unit OM (step S205). If the power wiring from the power supply unit 8 to the outdoor unit OM is broken, it may cause an electric shock due to electric leakage, and if it is short-circuited, it may cause a fire. Therefore, when it is determined that there is an abnormality in the power supply from the power supply unit 8 to the outdoor unit OM (Yes in step S205), the control unit 1 records in the storage unit 3 that there is an abnormality in the power supply. (Step S206), it is determined that there is an abnormality (step S217), and the initial diagnosis is completed (proceed to step S107 in FIG. 4).

When there is no abnormality in the power supply from the power supply unit 8 to the outdoor unit OM (No in step S205), the control unit 1 confirms the energized state of the four-way valve 22 (step S207). The control unit 1 records the result of the determination of confirming the energized state of the four-way valve 22 as the result 1 in the storage unit 3 (step S208). The diagnosis of the energized state of each part of the heat pump 2 is performed regardless of the presence or absence of an abnormality. Therefore, the result 1 stored in step S208 includes information on the presence or absence of an abnormality (leakage, short circuit, etc.) during energization. The same applies to the results 2 to 4 shown below.

Next, the control unit 1 confirms the energized state of the outdoor fan 26 (step S209). The control unit 1 records the result of the determination of confirming the energized state of the outdoor fan 26 as the result 2 in the storage unit 3 (step S210). Next, the control unit 1 confirms the energized state of the compressor 21 (step S211). The control unit 1 records the result of the determination of confirming the energized state of the compressor 21 as the result 3 in the storage unit 3 (step S212). Finally, the control unit 1 confirms the energized state of the indoor fan 27 (step S213). The control unit 1 records the result of the determination of confirming the energized state of the indoor fan 27 as the result 4 in the storage unit 3 (step S214).

The energization of each part of the heat pump 2 is confirmed in the above-mentioned order. In this order, when there is an abnormality, each part of the heat pump 2 is less likely to be damaged, and people in the vicinity are less likely to be damaged. However, the order of energization confirmation is not limited to this order.

Then, the control unit 1 confirms the results 1 to 4, which are the results of the energization confirmation of each part of the heat pump 2, and confirms whether or not at least one of them has an abnormality determination (step S215). Then, when at least one of the results 1 to 4 has an abnormality determination (Yes in step S215), the control unit 1 determines that there is an abnormality (step S217), and ends the initial diagnosis (FIG. 4). Step S107). Further, when there is no abnormality determination in the results 1 to 4 (No in step S215), the control unit 1 determines that there is no abnormality (step S216), and ends the initial diagnosis (in step S107 of FIG. 4). move on).

Returning to FIG. 4, the description of the operation of the air conditioner A will be continued. As described above, after the initial diagnosis is completed (after step S106), the control unit 1 confirms whether or not there is an abnormality in the air conditioner A in the initial diagnosis (step S107). If there is an abnormality in the air conditioner A in the initial diagnosis (Yes in step S107), the control unit 1 displays the diagnosis result on the display unit 71 of the remote controller 7 (step S108). Then, the diagnosis is finished. Examples of the display of the display unit 71 of the remote controller 7 include a point that the air conditioner A has an abnormality and cannot be used, a location where the abnormality has occurred, a type of abnormality (for example, an error number), and the like. However, it is not limited to this. The diagnosis result is as stored in the storage unit. That is, communication abnormality between the indoor unit IM and the outdoor unit OM, power supply abnormality, and energization abnormality of each part diagnosed by the initial diagnosis. If a diagnosis is made in addition to this, the diagnosis result is displayed. Further, as a method of notifying the diagnosis result, a method of displaying the diagnosis result on the display unit 71 of the remote controller 7 is adopted, but the method is not limited to this, and for example, the notification speaker 4 is used to notify by voice. You may.

For example, the diagnosis result may be displayed even when there is no abnormality, and in this case, characters or images that can recognize that there is no abnormality are displayed. The control unit 1 notifies the person in the living room Rm that the air conditioner A cannot be used by displaying the display unit 71 of the remote controller 7 indicating an abnormality. Then, by confirming the abnormality displayed on the display unit 71, the driving of the air conditioner A in which the abnormality has occurred is suppressed, so that secondary disasters such as electric shock due to electric leakage and ignition due to a short circuit are suppressed. be able to.

As shown above, it has been confirmed by the initial diagnosis that no particular problem occurs even if power is supplied to the air conditioner A, mainly the heat pump 2. On the other hand, due to a disaster such as an earthquake, the refrigerant may leak or become difficult to circulate due to damage to the refrigerant piping. In such a case, it is necessary to make a diagnosis by operating the heat pump 2 for a certain period of time (hereinafter, referred to as a drive diagnosis). Therefore, if there is no abnormality in the initial diagnosis (No in step S107), the control unit 1 puts the heat pump 2 into the operating state and puts the air conditioner A into the operating state (step S109). The heat pump 2 can perform a cooling operation or a heating operation, and is predetermined in the present embodiment.

The control unit 1 waits until a predetermined time elapses from the start of operation of the heat pump 2 (step S110). After a lapse of a predetermined time (Yes in step S110), the control unit 1 performs a drive diagnosis. The drive diagnosis will be described below with reference to the new drawings. FIG. 6 is a flowchart showing the operation of the drive diagnosis.

As shown in FIG. 6, the control unit 1 first measures the temperature of the refrigerant pipe of the heat pump 2 by the temperature detection unit 28, and acquires the measurement result (step S301). By driving the heat pump 2, the temperature of the refrigerant pipe changes depending on the location. As described above, by operating the heat pump 2, a temperature difference is generated between the discharge side pipe and the return pipe of the compressor 21. When this temperature difference does not occur or the temperature difference is small, it can be determined that the refrigerant filled in the heat pump 2 is leaking. Further, in some pipes other than the discharge side pipe and the return pipe of the compressor 21, the leakage of the refrigerant can be determined by measuring the temperature. Therefore, the temperature of the refrigerant pipe is measured, and from the result, the control unit 1 confirms whether or not there is an abnormality in the heat pump 2 (step S302).

If there is an abnormality in the heat pump 2 due to the temperature of the refrigerant pipe (Yes in step S302), the control unit 1 determines that the refrigerant is leaking from the refrigerant pipe and records the refrigerant leak in the storage unit 3 (step S303). ). Then, the control unit 1 determines that the air conditioner A has an abnormality (step S309), and ends the drive diagnosis (progresses to step S112 in FIG. 4).

When there is no abnormality in the heat pump 2 from the temperature of the refrigerant pipe (No in step S302), the control unit 1 measures the temperature in the living room Rm with the living room temperature sensor S1 (step S304). The control unit 1 calculates the temperature difference ΔT, which is the difference between the measured temperature in the living room Rm and the set temperature of the air conditioner A (step S305). In the air conditioner A, the heat pump 2 is operated so that the temperature in the living room Rm becomes the set temperature, and in the normal operating state, the temperature in the living room Rm approaches the set temperature.
