The operation of the refrigerant circulation module 400 will be explained in detail below according to different situations.

[0074] like Figure 8 As shown, when the refrigerant circuit is connected in the summer cooling mode, the third reversing valve 408 controls the first connecting pipeline 413 to be in a non-conducting state, and the second reversing valve 407 controls the second connecting pipeline 414 to be in a non-conducting state, and under the joint action of the second reversing valve 407 and the third reversing valve 408, the outlet of the compressor 401 is connected with the fourth valve port 4064, and the refrigerant is transmitted from the fourth valve port 4064 through the first valve port 4061 to the second refrigerant port 4022 of the first heat exchanger 402, and from the first refrigerant port 4021 to the fourth refrigerant port 4032 of the second heat exchanger 403, and enters the first reversing valve 406 from the third refrigerant port 4031 through the third valve port 4063, and returns to the compressor 401 from the second valve port 4062 through the gas-liquid separator 405 to form a loop.

[0075] like Fig. 9 As shown, when the refrigerant circuit is connected in the winter heating mode, the third reversing valve 408 controls the first connecting pipeline 413 to be in a non-conducting state, and the second reversing valve 407 controls the second connecting pipeline 414 to be in a non-conducting state, and under the joint action of the second reversing valve 407 and the third reversing valve 408, the outlet of the compressor 401 is connected with the fourth valve port 4064, and the refrigerant is transmitted from the fourth valve port 4064 through the third valve port 4063 to the third refrigerant port 4031 of the second heat exchanger 403, and is transmitted from the fourth refrigerant port 4032 to the first heat exchanger 402, and then enters the first reversing valve 406 from the second refrigerant port 4022 through the first valve port 4061, and returns to the compressor 401 from the second valve port 4062 through the gas-liquid separator 405 to form a loop.

[0076] It should be understood that the above-mentioned circuit conduction conditions are all under the premise of "sky-water-ground-water" (that is, the air conditioner and floor heating of the terminal device both exchange heat through the water channel). At this time, the second heat exchanger 403 takes effect in the circuit to perform water-to-water heat exchange. When the above-mentioned mode is under the premise of "sky-fluorine-ground-water" (that is, the air conditioner of the terminal device exchanges heat through Freon, and the floor heating exchanges heat through the water channel), the pipes that should be connected to the fourth refrigerant port 4032 and the third refrigerant port 4031 in the summer cooling mode will be connected to the heat exchanger in the air conditioning equipment of the terminal device respectively to achieve heat exchange refrigeration. The same is true in the winter heating mode (the floor heating maintains the above-mentioned connectivity).

[0079] like Fig.12As shown, when the refrigerant circuit is connected in the winter heating and domestic hot water heating mode, the third reversing valve 408 controls the compressor 401 outlet and the fourth valve port 4064 to be unable to be connected, and controls the compressor 401 outlet and the fifth refrigerant port 4041 of the third heat exchanger 404 to be connected. The second reversing valve 407 controls the second connecting pipeline 414 to be connected. The refrigerant enters the third heat exchanger 404 through the fifth refrigerant port 4041 from the outlet of the compressor 401, and enters the first reversing valve 406 through the sixth refrigerant port 4042 and the fourth valve port 4064, and enters the second heat exchanger 403 through the third valve port 4063 and the third refrigerant port 4031, and enters the first heat exchanger 402 through the fourth refrigerant port 4032 and the first refrigerant port 4021, and enters the first reversing valve 406 through the second refrigerant port 4022 and the first valve port 4061, and returns to the compressor 401 through the second valve port 4062 and the gas-liquid separator 405 to form a loop.

The refrigerant flowing through the first connecting pipeline 413 passes through the third heat exchanger 404, and flows to the fourth valve port 4064 through the second connecting pipeline 414, and enters the second heat exchanger 403 through the third valve port 4063 and the third refrigerant port 4031, and enters the first heat exchanger 402 through the fourth refrigerant port 4032 and the first refrigerant port 4021, and enters the first reversing valve 406 through the second refrigerant port 4022 and the first valve port 4061, and returns to the compressor 401 through the second valve port 4062 and the gas-liquid separator 405, forming a loop.

[0081] In some embodiments, Fig.14As shown, in the winter heating plus domestic hot water heating mode, a conduction mode of the refrigerant circuit is also included: the third reversing valve 408 controls the pipeline between the compressor 401 outlet and the fourth valve port 4064 to be connected to the first connecting pipeline 413, and the second reversing valve 407 controls the second connecting pipeline 414 to be connected to the third connecting pipeline 415. The refrigerant flows from the compressor 401 outlet through the fourth valve port 4064 and the first connecting pipeline 413 respectively. The refrigerant flowing through the fourth valve port 4064 enters the second heat exchanger 403 from the third valve port 4063 and the third refrigerant port 4031, and enters the first heat exchanger 402 through the fourth refrigerant port 4032 and the first refrigerant port 4021. The refrigerant flowing through the first connecting pipeline 413 enters the third heat exchanger 404 from the fifth refrigerant port 4041, and enters the pipeline between the fourth refrigerant port 4032 and the first refrigerant port 4021 through the sixth refrigerant port 4042, the second connecting pipeline 414, and the third connecting pipeline 415, and merges with the refrigerant flowing through the fourth valve port 4064. The merged refrigerant enters the first reversing valve 406 from the second refrigerant port 4022 and the first valve port 4061, and returns to the compressor 401 through the second valve port 4062 and the gas-liquid separator 405, forming a loop.

[0082] It can be understood that in other embodiments, Fig.14 On the basis of the connection relationship, the second reversing valve 407 and the fourth valve port 4064 can also be connected at the same time to realize the three-way circulation of the refrigerant.

[0083] In some embodiments, Fig.15 As shown, in the transition season when there is no need for cooling or heating but there is a need for heating domestic water, the heat pump circulation system can also perform a simple domestic hot water heating mode. In this mode, when the refrigerant circuit is connected, the third reversing valve 408 controls the compressor 401 outlet and the fourth valve port 4064 to be unable to be connected, and controls the compressor 401 outlet and the fifth refrigerant port 4041 of the third heat exchanger 404 to be connected. The second reversing valve 407 controls the second connecting pipeline 414 and the third connecting pipeline 415 to be connected. The refrigerant enters the third heat exchanger 404 from the outlet of the compressor 401 through the first connecting pipe 413 and the fifth refrigerant port 4041, and enters the terminal side heat exchanger 104 through the sixth refrigerant port 4042, the second connecting pipe 414, the third connecting pipe 415 and the first refrigerant port 4021, and enters the first reversing valve 406 through the second refrigerant port 4022 and the first valve port 4061, and returns to the compressor 401 through the second valve port 4062 and the gas-liquid separator 405 to form a loop.

[0084] It should be understood that the above-mentioned circuit conduction condition involves the circuit condition of the second heat exchanger 403, which is the same as the aforementioned "sky water and ground water". The heat pump system device 1 of the present application can be flexibly changed according to the two terminal equipment conditions of "sky water and ground water" or "sky fluorine and ground water".

[0085] like Figures 2 to 5 As shown, in some embodiments, the compressor 401, the second heat exchanger 403, the third heat exchanger 404, the gas-liquid separator 405, the first reversing valve 406, the second reversing valve 407, the third reversing valve 408, the first flow control valve 410, the second flow control valve 411, the heat exchanger 412, the first connecting pipeline 413, the second connecting pipeline 414, the third connecting pipeline 415, the one-way valve 409, the liquid storage tank 416 and the water pump 502 are all arranged in the second chamber 150, the first heat exchanger 402 is arranged in the first chamber 140, and the water tank 501 is arranged in the third chamber 160. To ensure the integration degree of the heat pump system equipment, reduce the volume of the equipment, and improve the space utilization. The water tank 501 with a larger weight among the equipment is horizontally arranged in the third chamber 160 located at the bottom of the equipment, which can ensure that the center of gravity of the equipment is lower and improve the stability of the equipment.

[0086] Specifically, Figure 2 As shown, the first heat exchanger 402 is plate-shaped and is vertically arranged on the support plate 120. Specifically, the horizontal cross-section of the first heat exchanger 402 is L-shaped and is vertically arranged on the edge of the support plate 120, which is used to save space, reduce the volume of the heat pump system equipment, and increase the heat exchange area of ​​the first heat exchanger 402.

[0087] In some embodiments, the first heat exchanger 402 is a finned heat exchanger.

[0088] In some embodiments, the outer wall of the first heat exchanger 402 can serve as a part of the side wall of the rack 100 , and define an accommodation space together with the side cover plate 112 .

[0089] Read also Figure 5 In some embodiments, the support plate 120 of the first chamber 140 is provided with at least two support members 122 for supporting the first heat exchanger 402 to prevent the lower end of the first heat exchanger 402 from directly contacting the support plate 120. The condensed water directly contacts the lower end of the first heat exchanger 402 and freezes, so that the condensed water cannot be discharged, and the frozen condensed water affects the operation of the first heat exchanger 402.

[0090] Specifically, there are multiple support members 122 , which are evenly distributed between the first heat exchanger 402 and the support plate 120 .

[0091] In some embodiments, the support member 122 includes a gasket.

[0092] Read also Figure 6 In some embodiments, the support plate 120 of the first chamber 140 is also provided with an ear plate, and the ear plate and the support plate 120 together define a receiving groove 1211. The receiving groove 1211 is formed below the first heat exchanger 402 and is used to receive condensed water to prevent the condensed water from spreading on the support plate 120.

[0093] Specifically, the accommodating groove 1211 is L-shaped, matching the shape of the first heat exchanger 402 , and has a width greater than the thickness of the first heat exchanger 402 .

[0094] In some embodiments, the ear plate may not be provided, and the accommodating groove 1211 may be formed by recessing the upper surface of the support plate 120 downward.

[0095] In some embodiments, at least one through hole is formed on the lower wall surface of the accommodating groove 1211 (ie, the supporting plate 120 ), and the through hole penetrates from the upper surface to the lower surface of the supporting plate 120 for discharging condensed water.

[0096] like Figure 4 and Figure 5 As shown, the compressor 401, the gas-liquid separator 405 and the water pump 502 are respectively fixed on the support plate 120 through the supporting structure, the second heat exchanger 403, the third heat exchanger 404 and the heat exchanger 412 are respectively fixed on the partition 130 through the supporting structure, and the first reversing valve 406, the second reversing valve 407, the third reversing valve 408, the first flow control valve 410, the second flow control valve 411, the first connecting pipeline 413, the second connecting pipeline 414, the third connecting pipeline 415, the one-way valve 409, the liquid storage tank 416 and other components are relatively fixed in the second chamber 150 through connecting pipes, so that the entire refrigerant circulation module is relatively firmly arranged in the frame 110.

[0097] Read also Figure 1 In some embodiments, the number of the side cover plates 112 is at least one, and several side cover plates 112 are detachably connected to facilitate disassembly and maintenance. In this embodiment, the number of side cover plates 112 corresponding to the second chamber 150 is three. When the components in the second chamber 150 need to be repaired, only the middle one of the three side cover plates 112 needs to be disassembled, which is convenient and quick.

[0098] like Figure 3As shown, the fan module 200 includes a bracket 220 and at least one fan 210, the fan 210 is arranged on the bracket 220, and the bracket 220 is vertically arranged on the support plate 120, so that the fan 210 rotates in the first chamber 140. In some embodiments, the number of the fans 210 is two, and the two fans 210 are respectively arranged at the upper part and the lower part of the bracket 220, and are both electrically connected to the electrical module 300.

[0099] The utility model also includes a second embodiment, and the main difference between this embodiment and the first embodiment is that:

[0100] In this embodiment, the support plate is vertically arranged in the accommodating space, and together with the partition plate, defines the accommodating space into three horizontally adjacent chambers. The first chamber and the third chamber are respectively arranged on both sides of the second chamber, or the first chamber and the second chamber are arranged adjacent to each other, and the third chamber is arranged on one side of the first chamber and the second chamber, and the water tank is vertically arranged in the third chamber which is also vertically arranged.

[0101] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
