[0013] In the fifth embodiment of the present invention, in the heat pump installation system according to the third embodiment, the initial setting step further includes setting the time, and a confirmation display is displayed after the time setting and before setting the main menu. According to this embodiment, by displaying a confirmation display before setting the main menu as one of the required settings including language setting and time setting, it is possible to more reliably prevent forgetting to attach the front grille to the outdoor unit body. [Example]

[0014] An embodiment of the present invention will now be described with reference to the drawings. FIG. 1 is a configuration diagram of a heat pump device according to this embodiment. As shown in FIG. 1( a ), the heat pump device according to this embodiment includes a refrigerant circuit 10 and a heat medium circuit 20 . In the refrigerant circuit 10, a compressor 11, a user-side heat exchanger 12, an expansion device 13, and a heat-source-side heat exchanger 14 are connected by refrigerant piping, and the refrigerant circulates. The heat medium circuit 20 circulates the heat medium heated in the use-side heat exchanger 12 by the refrigerant discharged from the compressor 11 to the use-side terminal 1. The heat medium circuit 20 is equipped with a gas-liquid separator 30 that separates the gas in the heat medium circuit 20 from the heat medium, a transfer pump 21 that circulates the heat medium, and a heater 22 that heats the heat medium. The heat medium circuit 20 is further provided with a pressure relief valve 40. The gas-liquid separation section 30 is connected to a discharge device 50 that discharges the gas separated in the gas-liquid separation section 30.

[0015] The transfer pump 21 is disposed in the indoor unit 2. The indoor unit 2 is equipped with a display unit 61 that prompts the user to make various settings before operating the heat pump device, an input unit 62 through which the installer inputs the settings, and a control unit 63 that causes the display unit 61 to display the settings input through the input unit 62. The display unit 61, the input unit 62, and the control unit 63 may be provided separately from the indoor unit 2, for example, as a remote control device. The refrigerant circuit 10 preferably includes a four-way valve 15 for switching the flow of the refrigerant. A blower fan 16 is provided at a position opposite the heat source side heat exchanger 14 . The refrigerant used is propane, which is a flammable refrigerant, although any of the mildly flammable refrigerants R1234yf, R1234ze, and R32 may be used instead of the flammable refrigerant. The heat transfer medium is water or antifreeze. The gas-liquid separator 30 and the pressure relief valve 40 are disposed in the heat medium circuit 20 downstream of the utilization-side heat exchanger 12 .

[0016] The heat medium can be heated or cooled by switching the four-way valve 15 . When heating a heat medium, the refrigerant compressed by the compressor 11 flows sequentially through the user-side heat exchanger 12, the expansion device 13, and the heat-source-side heat exchanger 14, and the refrigerant is decompressed by the expansion device 13 and absorbs heat in the heat-source-side heat exchanger 14 before being drawn into the compressor 11. In this way, the refrigerant compressed by the compressor 11 is caused to flow through the user-side heat exchanger 12, thereby heating the heat medium. When cooling a heat medium, the refrigerant compressed by the compressor 11 flows sequentially through the heat source side heat exchanger 14, the expansion device 13, and the user side heat exchanger 12, and the refrigerant compressed by the compressor 11 releases heat in the heat source side heat exchanger 14, and the refrigerant that has been decompressed by the expansion device 13 and absorbs heat in the user side heat exchanger 12 is drawn into the compressor 11. In this way, the heat medium can be cooled by being decompressed by the expansion device 13 and absorbing heat in the user side heat exchanger 12.

[0017] The heat medium cooled or heated in the use-side heat exchanger 12 is transported to the use-side terminal 1 by the transport pump 21, and the heat medium that absorbs or releases heat at the use-side terminal 1 is returned to the use-side heat exchanger 12.

[0018] In particular, when a plate-type heat exchanger is used as the user-side heat exchanger 12, there is a possibility that the refrigerant flowing through the refrigerant circuit 10 may be mixed into the heat medium circuit 20 due to damage to the user-side heat exchanger 12. In this way, the refrigerant leaked into the heat medium circuit 20 can be separated from the liquid-phase heat medium in the gas-liquid separator 30 and then discharged from the discharge device 50 . The gas-liquid separation section 30 is arranged in the heat medium circuit 20 downstream of the user-side heat exchanger 12 within the outdoor unit 3, thereby preventing refrigerant leaking into the heat medium circuit 20 from being discharged to the user-side terminal 1. The gas-liquid separation section 30 may be placed downstream of the user side heat exchanger 12 and upstream of the user side terminal 1, or upstream of the indoor unit 2 if an indoor unit 2 is provided, but it is preferable to place it within the outdoor unit 3, as in this embodiment. The gas-liquid separator 30 can separate the leaked refrigerant as well as the air present in the heat medium circuit 20. In particular, it is used to bleed air from the heat medium circuit 20 when filling the heat medium circuit 20 with a heat medium during installation of a heat pump device construction system, etc. In this embodiment, the transfer pump 21 is disposed in the indoor unit 2, but the transfer pump 21 may be disposed in the outdoor unit 3.

[0019] FIG. 1(b) is a perspective view showing the outdoor unit body without a front grill attached thereto, and FIG. 1(c) is a perspective view showing the outdoor unit body with a front grill attached thereto. The outdoor unit 3 according to this embodiment is shipped from the factory with the front grill 3A detached from the outdoor unit main body 3B, and the front grill 3A is attached to the outdoor unit main body 3B at the installation site. The outdoor unit body 3B is formed with a blower fan opening 3C, and a blower fan 16 is disposed at a position facing the blower fan opening 3C. In this embodiment, the front grill 3A is an integrated type, but it may be a left-right separated type.

[0020] FIG. 2 shows a setting flow of the heat pump installation system according to this embodiment. The control unit 63 has an initial setting step (S70) and a main menu setting step (S80), and normal operation is performed (S90) after the initial setting step (S70).

[0021] In the initial setting step (S70), language setting (S71), time display method setting (S72), time setting (S73), a confirmation display to confirm the installation of the front grill 3A (S74), and a display encouraging installation if the front grill 3A is not installed (S75) are performed.

[0022] In the language setting (S71), the subsequent display language is set from among, for example, English, French, German, and Italian. The display language is selected by the input unit 62 from among the languages ​​displayed on the display unit 61, and the control unit 63 displays the subsequent information in the selected display language. In the time display method setting (S72), for example, 24-hour display or AM / PM display is set. The time display method is selected by the input unit 62 from the 24-hour display or AM / PM display displayed on the display unit 61, and the time is displayed in the selected display method by the control unit 63. In the time setting (S73), the year, month, date, and current time are set.

[0023] In the confirmation display (S74), the installation of the front grille 3A is confirmed, and when "Installed" is selected by the input unit 62 (Yes in S74), the process proceeds to the main menu setting (S80). In the confirmation display (S74), if "Not attached" is selected by the input unit 62 (No in S74), an attachment prompt display (S75) is displayed, and the confirmation display (S74) is displayed again, without proceeding to the main menu setting (S80). In the main menu setting (S80), for example, any of function setup, system check, personal setup, service contact, and installer setup is set.

[0024] As described above, the control unit 63 in this embodiment causes the display unit 61 to display a confirmation display confirming that the front grill 3A has been attached to the outdoor unit body 3B before operation begins. By displaying the confirmation display on the display unit 61 before operation begins in this way, it is possible to prevent forgetting to attach the front grill 3A to the outdoor unit body 3B, and operation will not be performed with the blower fan 16 exposed. Furthermore, in this embodiment, if the content input in the input unit 62 in response to the confirmation display indicates that the front grille 3A is not yet attached, the control unit 63 does not display new settings on the display unit 61, but instead urges the user to attach the front grille 3A to the outdoor unit body 3B. In this way, since new settings cannot be made if the front grille 3A is not yet attached, it is possible to more reliably prevent the user from forgetting to attach the front grille 3A to the outdoor unit body 3B.

[0025] Furthermore, the control unit 63 in this embodiment has an initial setting step (S70) for at least setting the language (S71), and a main menu setting (S80), and a confirmation display (S74) is displayed in the initial setting step (S70). By displaying the confirmation display (S74) in the initial setting step (S70) in this way, it is possible to more reliably prevent forgetting to attach the front grille 3A to the outdoor unit body 3B. In this embodiment, the confirmation display (S74) is displayed after the language setting (S71) and before the main menu setting (S80). By displaying the confirmation display (S74) as one of the required settings including the language setting (S71) before the main menu setting (S80), it is possible to more reliably prevent forgetting to attach the front grille 3A to the outdoor unit main body 3B. In this embodiment, the confirmation display (S74) is displayed after the time setting (S73) and before the main menu setting (S80). By displaying the confirmation display (S74) as one of the required settings including the language setting (S71) and the time setting (S73) before the main menu setting (S80), it is possible to more reliably prevent forgetting to attach the front grille 3A to the outdoor unit main body 3B.
