For example, the operator selects a refrigerant circuit diagram to be displayed by selecting and inputting a management address.

In step S06, the display device 10 waits for the selection of the refrigerant circuit diagram to be displayed to be completed, and when the selection of the refrigerant circuit diagram to be displayed is completed, the process proceeds to step S08.

It is attached. For example, “0” which is the name identification information 802 of “300” and “3” which is the type identification information 801 are used to give the name “EV” and “1” which is the name identification information 802 of “310”. ”And“ 3 ”, which is the type identification information 801, are given the name“ EV — 2 ”, and“ 2 ”, which is the name identification information 802 of“ 320 ”, and“ 3 ”, which is the type identification information 801. , “EV — 3” is assigned.

The refrigeration cycle apparatus of Modification 3 that is not shown includes two expansion valves connected in parallel to each other, and one expansion valve connected in series with the two expansion valves connected in parallel. In the second modification, refrigerant circuit diagrams relating to these three expansion valves are displayed.

Display device 10 generates refrigerant circuit diagram data 903 of “300” “301” “310” shown in FIG. 19 from identification data group 322 acquired from the refrigeration cycle device (not shown) of Modification 3. Note that state data 953 is given to the refrigerant circuit diagram data 903. Then, by using “0”, “1”, and “0” that are the connection information 803 of the identification information 800 of “300”, “301”, and “310”, the serial connection or parallel connection of the graphic symbols is determined. That is, since “300” and “301” have the latter connection information 803 of “1”, it is determined that “300” and “301” are connected in parallel to each other. Since “301” and “310” have the latter connection information 803 of “0”, it is determined that “310” is connected in series with “301” and “310” connected in parallel to each other. To do. Then, the graphic symbol of the expansion valve corresponding to “3” as the type identification information 801 of “300” and the graphic symbol of the expansion valve corresponding to “3” as the type identification information 801 of “301” are used as the refrigerant. Connected in parallel with a solid line graphic symbol corresponding to the piping, and the expansion valve graphic symbol corresponding to “3” which is the type identification information 801 of “310” is connected in series with the two expansion valves connected in parallel with each other A connected refrigerant circuit diagram is generated. In the third modification, “0” and “1” that are connection information 803 of “300” and “301” in the refrigerant circuit diagram data 903 are used to give names to the expansion valves connected in parallel. For example, “0” which is the connection information 803 of “300” and “3” which is the type identification information 801 are used to give the name “EV_A” and “1” which is the connection information 803 of “301”. The name “EV_B” is assigned using “3” which is the type identification information 801.

In addition, as a case where the components forming the refrigerant circuit 5A are connected in parallel, for example, when an expansion valve having a small opening area is arranged in parallel to increase the refrigerant flow rate through which the refrigerant flows, and the compressor in parallel There are cases where it is arranged to increase the output of the compressor.

[Modification 4]
FIG. 21 is a diagram showing refrigerant circuit diagram data of Modification Example 4, which is a modification example of the refrigerant circuit diagram data shown in FIG. 13, and FIG. 22 is a refrigerant generated from the refrigerant circuit diagram data shown in FIG. It is a figure which shows a circuit diagram. Compared with the refrigerant circuit diagram data 900 of the first embodiment described in FIG. 13, the refrigerant circuit diagram data 904 of the modification 4 illustrated in FIG. 21 includes piping information “FFF”. The piping information “FFF” is information relating to the length of the refrigerant piping 70 and is stored in the outdoor unit storage unit 320 illustrated in FIG. 2 as identification information 800 that forms the identification data group 322.

The display device 10 generates the refrigerant circuit diagram data 904 of “000”, “500”, “FFF”, and “300” shown in FIG. 21 from the identification data group 322 acquired from the refrigeration cycle device (not shown) of Modification 4. Then, the refrigerant circuit diagram shown in FIG. 22 is displayed. Note that state data 954 is given to the refrigerant circuit diagram data 904. The display device 10 shortens the length of the refrigerant pipe between “000” and “500”, which are refrigerant pipes before “FFF”, and “500”, which is the refrigerant pipe after “FFF”. A refrigerant circuit diagram in which the length of the refrigerant pipe between “300” is increased is generated and displayed on the display unit 101.

For example, the detection results of a detection device such as a temperature sensor and a pressure sensor vary depending on the arrangement position. This is because, for example, when the length of the refrigerant pipe is long, the refrigerant exchanges heat with the outside air, or pressure loss occurs, so that the temperature and pressure of the refrigerant change. The refrigerant circuit diagram of Modification 4 includes information on the length of the refrigerant pipe, and specifies the arrangement position of the components that form the refrigerant circuit and the arrangement position of the detection device that detects the state of the refrigerant circuit. Therefore, construction or maintenance of the refrigeration cycle apparatus can be performed with high accuracy.

The “refrigeration cycle device storage unit” of the present invention corresponds to the outdoor unit storage unit 320 or the indoor unit storage unit 420.

Further, for example, the outdoor unit storage unit 320 stores the identification information 800 in the order of display on the display unit 101, and the data structure is simplified. As a result, the amount of data communication between the display device 10 and the refrigeration cycle device 5 when the display device 10 generates the refrigerant circuit diagram is suppressed.

Further, for example, the identification information 800 identifies type identification information 801 for identifying the types of the plurality of components and at least one detection device, and the unique names of the plurality of components and the at least one detection device. Since the name identification information 802 and the connection information 803 indicating the state of serial or parallel connection of a plurality of components are included, the refrigeration cycle system 1 of this embodiment has a complex refrigerant circuit. A refrigerant circuit diagram of the refrigeration cycle apparatus 5 can be displayed.
