[EMBODIMENT]

[0021] An embodiment of the present invention will be described below with reference to the drawings.

[0022] Figs. 1 are diagrams showing a configuration of a heat pump device according to the embodiment.

[0023] As shown in Fig. 1(a), the heat pump device of the embodiment includes a refrigerant circuit 10 and a heat medium circuit 20.

[0024] The refrigerant circuit 10 is formed by connecting a compressor 11, a use-side heat exchanger 12, an expansion device 13 and a heat source-side heat exchanger 14 through a refrigerant pipe, and refrigerant circulates through the refrigerant circuit 10.

[0025] In the heat medium circuit 20, heat medium which is heated by the use-side heat exchanger 12 is circulated through a use-side terminal 1 by refrigerant discharged from the compressor 11.

[0026] The heat medium circuit 20 includes a vapor-liquid separator 30 which separates gas in the heat medium circuit 20 from heat medium, a transportation pump 21 through which heat medium circulates, and a heater 22 for heating heat medium.

[0027] The heat medium circuit 20 further includes a pressure relief valve 40. A discharge device 50 is connected to the vapor-liquid separator 30. The discharge device 50 discharges gas which is separated by the vapor-liquid separator 30.

[0028] The transportation pump 21 is placed in an indoor unit 2.

[0029] The indoor unit 2 includes a display 61 for prompting to set various things before the heat pump device is operated, an inputting section 62 through which a contractor inputs setting content, and a controller 63 for displaying on the display 61 depending upon the setting content which is input by means of the inputting section 62.

[0030] The display 61, the inputting section 62 and the controller 63 may be operated by remote control devices and may be provided separately from the indoor unit 2.

[0031] It is preferable that the refrigerant circuit 10 includes a four-way valve 15 for switching flow of refrigerant.

[0032] An air-blowing fan 16 is provided at a position opposed to the heat source-side heat exchanger 14.

[0033] As the refrigerant, propane which is flammable refrigerant is used. Instead of the flammable refrigerant, it is possible to use any of R1234yf, R1234ze and R32 which are mildly flammable refrigerants.

[0034] Water or antifreeze liquid is used as the heat medium.

[0035] The vapor-liquid separator 30 and the pressure relief valve 40 are placed in the heat medium circuit 20 located downstream of the use-side heat exchanger 12.

[0036] It is possible to heat or cool the heat medium by switching of the four-way valve 15.

[0037] When the heat medium is heated, refrigerant which is compressed by the compressor 11 flows through the use-side heat exchanger 12, the expansion device 13 and the heat source-side heat exchanger 14 in this order, the refrigerant is decompressed by the expansion device 13, and the refrigerant which absorbs heat in the heat source-side heat exchanger 14 is sucked into the compressor 11. By flowing the refrigerant which is compressed by the compressor 11 to the use-side heat exchanger 12 in this manner, heat medium can be heated.

[0038] When heat medium is cooled, refrigerant which is compressed by the compressor 11 flows through the heat source-side heat exchanger 14, the expansion device 13 and the use-side heat exchanger 12 in this order, the refrigerant which is compressed by the compressor 11 radiates heat in the heat source-side heat exchanger 14, the refrigerant is decompressed by the expansion device 13, and the refrigerant which absorbs heat in the use-side heat exchanger 12 is sucked into the compressor 11. The refrigerant is decompressed in the expansion device 13 and heat of the refrigerant is absorbed in the use-side heat exchanger 12 in this manner. According to this, the heat medium can be cooled.

[0039] The heat medium which is cooled or heated by the use-side heat exchanger 12 is transported to the use-side terminal 1 by the transportation pump 21, and the heat medium which is heat-absorbed or heat-radiated in the use-side terminal 1 is returned to the use-side heat exchanger 12.

[0040] Especially when a plat-type heat exchanger is used as the use-side heat exchanger 12, there is a possibility that refrigerant flowing through the refrigerant circuit 10 is mixed into the heat medium circuit 20 due to damage of the use-side heat exchanger 12.

[0041] Refrigerant which leaks into the heat medium circuit 20 in this manner can be discharged from the discharge device 50 by separating the refrigerant from liquid phase heat medium by the vapor-liquid separator 30.

[0042] The vapor-liquid separator 30 is placed in the heat medium circuit 20 located downstream of the use-side heat exchanger 12 in an outdoor unit 3. Therefore, refrigerant which leaks into the heat medium circuit 20 is suppressed from flowing into the use-side terminal 1.

[0043] When the indoor unit 2 is provided downstream of the use-side heat exchanger 12 and upstream of the use-side terminal 1, the vapor-liquid separator 30 may be placed upstream of the indoor unit 2, but it is preferable that e vapor-liquid separator 30 is placed in the outdoor unit 3 as in this embodiment.

[0044] The vapor-liquid separator 30 separates leaked refrigerant. In addition to this, the vapor-liquid separator 30 can separate air existing in the heat medium circuit 20. Especially when heat medium is charged into the heat medium circuit 20 such as when the construction system of the heat pump device is installed, the vapor-liquid separator 30 is utilized for venting air from the heat medium circuit 20.

[0045] Although the transportation pump 21 is placed in the indoor unit 2 in this embodiment, the transportation pump 21 may be placed in the outdoor unit 3.

[0046] Fig. 1(b) is a perspective view showing a state where the front surface grill is not yet attached to the outdoor unit body, and Fig. 1(c) is a perspective view showing a state where the front surface grill is attached to the outdoor unit body.

[0047] The outdoor unit 3 of the embodiment is shipped from a factory in a state where the front surface grill 3A is detached from the outdoor unit body 3B, and the front surface grill 3A is attached to the outdoor unit body 3B in a construction field site.

[0048] The air-blowing fan opening 3C is formed in the outdoor unit body 3B, and the air-blowing fan 16 is placed at a position opposed to the air-blowing fan opening 3C.

[0049] Although the front surface grill 3A is integrally formed in this embodiment, the front surface grill 3A may be separated laterally.

[0050] Fig. 2 is a setting flowchart carried out by the construction system of the heat pump device of the embodiment.

[0051] The controller 63 includes an initial setting step (S70) and a main menu setting (S80), and normal operation is carried out (S90) after the initial setting step (S70).

[0052] In the initial setting step (S70), the following settings and displays are carried out, i.e., a language setting (S71), a time display method setting (S72), a time setting (S73), a confirmation display (S74) for confirming that the front surface grill 3A is attached, and an attachment prompting display (S75) which is carried out when the front surface grill 3A is not yet attached.

[0053] In the language setting (S71), subsequent display language is set from English, French, German and Italian for example. The display language is selected by the inputting section 62 from languages displayed on the display 61, and subsequent display is carried out in selected display language by the controller 63.

[0054] The time display method setting (S72) sets 24 hours display or AM/PM display. The time display method is selected by the inputting section 62 from 24 hours display or AM/PM display which is displayed on the display 61, and the controller 63 displays time in selected display method. The time setting (S73) sets year, month and day, and current time.

[0055] The confirmation display (S74) confirms "attachment" of the front surface grill 3A, and if the inputting section 62 selects "attached" (Yes in S74), the procedure proceeds to the main menu setting (S80).

[0056] In the confirmation display (S74), if "not-yet attached" is selected by the inputting section 62 (No in S74), the attachment prompting display (S75) is carried out, the confirmation display (S74) is newly carried out, and the procedure does not proceed to the main menu setting (S80).

[0057] The main menu setting (S80) sets any of function setup, system check, personal setup, service contact, and installer setup for example.

[0058] As described above, the controller 63 of the embodiment displays, on the display 61, the confirmation display which confirms that the front surface grill 3A is attached to the outdoor unit body 3B before the operation is carried out. By displaying the confirmation display on the display 61 before the operation is carried out in this manner, it is possible to prevent the possibility that a contractor forgets to attach the front surface grill 3A to the outdoor unit body 3B, and operation is not carried out in a state where the air-blowing fan 16 is exposed.

[0059] In this embodiment, when content which is input into the confirmation display by the inputting section 62 is "not-yet attached", new setting is not displayed into the confirmation display by the controller 63, and a contractor is prompted to attach the front surface grill 3A to the outdoor unit body 3B. Since new setting cannot be carried out when the front surface grill 3A is not yet attached to the outdoor unit body 3B, it is possible to further reliably prevent the possibility that a contractor forgets to attach the front surface grill 3A to the outdoor unit body 3B.

[0060] The controller 63 of this embodiment includes the initial setting step (S70) which carries out at least the language setting (S71), and the main menu setting (S80), and the confirmation display (S74) is carried out in the initial setting step (S70). By carrying out the confirmation display (S74) in the initial setting step (S70) in this manner, it is possible to further reliably prevent the possibility that a contractor forgets to attach the front surface grill 3A to the outdoor unit body 3B.

[0061] In this embodiment, the confirmation display (S74) is carried out after the language setting (S71) and before the main menu setting (S80). By carrying out the confirmation display (S74) as one of indispensable settings including the language setting (S71) before the main menu setting (S80) in this manner, it is possible to further reliably prevent the possibility that a contractor forgets to attach the front surface grill 3A to the outdoor unit body 3B.

[0062] In this embodiment, the confirmation display (S74) is carried out after the time setting (S73) and before the main menu setting (S80). By carrying out the confirmation display (S74) as one of indispensable settings including the language setting (S71) and the time setting (S73) before the main menu setting (S80) in this manner, it is possible to further reliably prevent the possibility that a contractor forgets to attach the front surface grill 3A to the outdoor unit body 3B.
