  A communication unit (display device side interface) 605 is an interface capable of transmitting and receiving information to and from the outdoor unit 20. The communication unit 605 transmits the operation setting information input or read to the operation unit 603 to the outdoor unit 20, and the outdoor unit 20 indicates the test operation itself during the test operation or the operation status of each operation mechanism. The test operation itself during the test operation itself or information indicating the time required to complete the operation of each operation mechanism is received.

  Next, a first embodiment of the process during the trial operation of the air conditioner body 10 and the display device 60 will be described. FIG. 4 is a flowchart for explaining the flow of processing during the test operation of the air conditioner body 10 and the display device 60. FIG. 5 is an example of a display screen showing the time required until the operation of each operation mechanism in the trial operation is completed.

  When the operator operates the operation unit 603 of the display device 60 to input a test operation start instruction and the control unit 601 receives a test operation start instruction (YES in S1), the communication unit 605 starts the test operation. The instruction is transmitted to the outdoor unit 20 of the air conditioner body 10 (S2).

  In the outdoor unit 20 of the air conditioner body 10, when the data transmission / reception unit 204 receives an instruction to disclose the trial operation (SS 1), the operation control unit 203 starts the trial operation in each operation mechanism of the outdoor unit 20 and the indoor unit 30. (SS2). After the start of the test operation, the detection unit 201 detects the operation status of each operation mechanism of the outdoor unit 20 and the indoor unit 30 that performs the test operation, as described above, by the outdoor air temperature sensor (To). Temperature, indoor air temperature detected by a room temperature sensor (Tr), high and low pressure refrigerant pressures of the compressor 21 detected by the pressure detectors (HS1, HS2, LS), detected by a discharge pipe temperature sensor (Td) The discharge pipe temperature of the compressor 21, the external heat exchange temperature detected by the external heat exchange temperature sensor (Tc), the internal heat exchange temperature detected by the internal heat exchange temperature sensor (Te), and the power supply voltage sensor 58. Based on various data of the refrigerant quantity in the refrigerant circuit 11 detected by the refrigerant quantity detection unit, such as the power supply voltage to be detected, the power supply current detected by the power supply current sensor 59, etc. And out of (SS3).

  Subsequently, the calculation unit 206 takes the time required from the time when the operation state is detected to the end of the operation of each operation mechanism during the trial operation according to the operation state of each operation mechanism detected by the detection unit 201. Is read from the storage unit 205 for each operating mechanism (SS4). The data transmitting / receiving unit 204 transmits the operation status of each operation mechanism obtained in SS3 and the required time for each operation mechanism calculated in SS4 to the display device 60 (SS5).

  When the communication unit 605 of the display device 60 receives the operation status and the required time of each operation mechanism (S3), the control unit 601 displays the received operation status and the required time of each operation mechanism on the display unit 602. (S4). At this time, as shown in FIG. 5, the control unit 601 causes the display unit 602 to display the received time required for each operating mechanism on a graphic display. The control unit 601 holds image data necessary for graphic display corresponding to the time required for each operation mechanism.

  Next, 2nd Embodiment of the process at the time of the test run operation | movement of the air conditioner main body 10 and the display apparatus 60 is described. FIG. 6 is a flowchart for explaining the second embodiment of the process during the trial operation of the air conditioner body 10 and the display device 60. FIG. 7 is an example of a display screen showing the time required for the end of the operation in the trial operation. However, the description of the same processing as that of the first embodiment shown in FIG. 4 is omitted.

  That is, as a process for calculating the required time until the end of the trial operation performed in the air conditioner 100, (1) the calculation unit 206 calculates the required time for the test operation itself stored in the storage unit 205 ( Using the above calculation formula or required time information), calculate the required time of the entire test operation required from the operation status detected by the detection unit 201 to the completion of the test operation, or (2) as shown below The time required for the end of the test run corresponding to the operation status of each operation mechanism is read from the storage unit 205 for each operation mechanism, and the entire test operation is determined from the time required for each operation mechanism until the end of the test operation. There are two ways to calculate the required time.

  As in the first embodiment, in the outdoor unit 20 of the air conditioner body 10, when the data transmission / reception unit 204 receives a disclosure instruction for the trial operation (SS11) and the trial operation is started (SS12), the second operation is performed. In the embodiment, the operation state of each of the plurality of operation mechanisms when the plurality of operation mechanisms perform a series of trial operation operations in conjunction with each other (SS13), and the calculation unit 206 detects each operation detected by the detection unit 201. In accordance with the operating status of the mechanism, the time required for the end of the trial run corresponding to the operating status is read from the storage unit 205 for each operating mechanism and calculated (SS14).

  Then, the calculation unit 206 calculates the required time for the entire series of trial operation operations from the required time information of each operation mechanism until the trial operation operation is read out in SS14 (SS15). For example, when the operation of the first operation mechanism is completed and the operation of the other second operation mechanism is started, the calculation unit 206 calculates the time required for the first operation mechanism. When the time required for the second operation mechanism is added or when the operation of one operation mechanism and another operation mechanism are performed in parallel, the time required for one operation mechanism (required for the first operation mechanism) The time required for the entire series of test run operations is calculated by selecting the longer required time of another operating mechanism (including the required time obtained by adding the time and the required time of the second operating mechanism).

  The data transmitting / receiving unit 204 transmits the operation status and required time of each operation mechanism that performs the series of trial operation, and further, the required time for the series of trial operation to the display device 60 (SS16).

  When the communication unit 605 of the display device 60 receives the operation status and required time of each operation mechanism that performs the series of trial operation, and further, the required time for the series of trial operation (S13), the control unit 601 The display section 602 displays the operation status and required time of each operation mechanism that performs the test operation of the above, and the required time for the series of test operation (S14). At this time, as shown in FIG. 7, the control unit 601 causes the display unit 602 to display the required time of each operation mechanism that performs the series of trial operation, and further the required time for the series of trial operation. The control unit 601 holds image data necessary for graphic display corresponding to each required time.

The data transmitting / receiving unit 204 transmits the operation status and required time of each operation mechanism for the series of trial operation, and the required time for the series of trial operation to the display device 60 (SS26).

  Here, in the third embodiment, when one of a plurality of operation mechanisms that perform the series of trial operation operations causes a delay during the trial operation, the storage unit 205 uses the delay as a factor. A delay time generated in another operation mechanism that performs the series of trial operation is stored. For example, when a refrigerant leak or the like occurs and it takes time until the refrigerant amount in the refrigerant circuit 11 recovers to a specified amount, and the time becomes a delay time, the refrigerant leak is detected and The storage unit 205 stores, as a delay time generated in the other operation mechanism, a time during which the delay from the refrigerant amount to the refrigerant reaching the specified amount delays the operation of the compressor 21 during the trial operation. .

  When the detection unit 201 detects the occurrence of a delay in any one of the plurality of operation mechanisms that perform the series of trial operation, the calculation unit 206 determines the operation mechanism from the storage unit 205 (YES in SS27). After the delay times generated in the other operation mechanisms due to the delay are read and added, the required time for each operation mechanism and the required time for the series of trial operation are calculated again (SS28).

  The data transmission / reception unit 204 includes the operation status of each operation mechanism detected by the detection unit 201 at this time, the required time for each operation mechanism recalculated after the delay, and the required time for the series of trial operation operations. Are transmitted to the display device 60 (SS29). The processes of SS27 to SS29 are repeated until the detection unit 201 detects the end of the series of test operation operations (SS30). When the detection unit 201 detects the end of the series of trial operation (YES in SS30), the data transmission / reception unit 204 transmits a signal indicating that the series of trial operation is completed to the display device 60. (SS31). Note that the detection unit 201 detects that the series of test operation operations has been completed, for example, when the detection values for all the operation mechanisms have reached the target values.

The required time for each operation mechanism and the required time for the series of trial operation are displayed on the display unit 602 (S26). When the communication unit 605 of the display device 60 does not receive the time required for each operation mechanism after the delay and the time required for the series of test operation operations (NO in S25), the display process in S26 is naturally performed. Absent. The processes of S25 and S26 are repeated until the communication unit 605 receives a signal indicating that the series of trial operation has been completed from the data transmitting / receiving unit 204 of the air conditioner body 10 (S27).

When air volume adjustment, target room temperature, etc.) are input to the operation unit 603 (YES in S41), the communication unit 605 transmits the input operation settings to the air conditioner body 10 (S42).

  In the air conditioner body 10, when the data transmitting / receiving unit 204 receives the operation setting (SS41), the operation setting storage unit 202 stores the received operation setting (SS42). The operation control unit 203 drives and controls each operation mechanism of the air conditioner main body 10 according to the operation setting stored in the operation setting storage unit 202 (SS43).

  Next, a second embodiment of processing when inputting operation settings of the air conditioner body 10 on the display device 60 will be described. FIG. 10 is a flowchart showing a second embodiment of processing when the operation setting of the air conditioner main body 10 is input in the display device 60.

  The operator detects that a storage medium such as CF is inserted into the receiving port 604a of the display device 60, and the reader / writer unit 604 detects that data can be read from the inserted storage medium. (YES in S51), the reader / writer unit 604 reads the operation setting stored in the storage medium (S52). The communication unit 605 transmits the read operation setting to the air conditioner body 10 (S53).

  When the data transmission / reception unit 204 of the air conditioner body 10 receives the operation setting (SS51), the operation setting storage unit 202 stores the received operation setting (SS52), and the operation control unit 203 stores the operation setting storage. Each operation mechanism of the air conditioner body 10 is driven and controlled according to the operation setting stored in the unit 202 (SS53).
