[0047] Figures 1 to 3 The heat pump system equipment in the first embodiment of the utility model is shown, and the heat pump system equipment includes a frame 100 and a refrigerant circulation module 400, wherein the refrigerant circulation module 400 is arranged in the frame 100, and the refrigerant circulation module 400 forms a refrigerant circuit for heat exchange with domestic water or terminal equipment.

[0048] Specifically, Figure 2 and Figure 3 As shown, the rack 100 includes a frame 110 and a partition 130, and the refrigerant circulation module 400 is disposed in the frame 110. The partition 130 defines two adjacent chambers on the left and right in the frame 110. Figure 4 and Figure 5The refrigerant circulation module 400 includes a compressor 401, an indoor heat exchanger 403, and a domestic hot water heat exchanger 404, which are interconnected to form a refrigerant circuit. The indoor heat exchanger 403 forms a terminal circuit with the terminal device, which is used to perform heat exchange with the refrigerant circulation circuit to achieve the cooling and heating effects of the terminal device. The domestic hot water heat exchanger 404 is used to connect with the equipment for storing domestic water to form a water circulation circuit, perform heat exchange with the refrigerant circulation module, and achieve the heating of domestic water. Among them, the compressor 401 is arranged on the bottom plate of the chamber where it is located, and the domestic hot water heat exchanger 404 and / or the indoor heat exchanger 403 are arranged on the partition 130.

[0049] By integrating the indoor heat exchanger 403 and the domestic hot water heat exchanger 404 into the rack 100, the heat pump system equipment can realize the cooling and heating of the terminal equipment and the function of preparing domestic hot water, thereby improving the integration of the HVAC system. At the same time, since the compressor 401 is arranged on the bottom plate of the chamber where it is located, and the domestic hot water heat exchanger 404 and / or the indoor heat exchanger 403 are arranged on the partition 130, the domestic hot water heat exchanger 404 and / or the indoor heat exchanger 403 can effectively utilize the upper space of the chamber, improve the utilization rate of the internal space of the rack 100, and realize the miniaturization of the heat pump system equipment. At the same time, since the compressor 401 with larger vibration is arranged on the bottom plate, and the heat exchanger with smaller vibration is arranged on the partition 130, the vibration of the heat pump system equipment during operation can be effectively reduced, the center of gravity of the equipment can be lowered, and the stability of the heat pump system equipment can be improved.

[0050] like Figure 1 As shown, in this embodiment, the frame 110 is in a cubic shape, and the partition 130 is also arranged in a rectangular shape, so that the frame 100 is in a cubic shape as a whole. Figure 2 and Figure 3 The rack 100 further includes a support plate 120, which is rectangular and horizontally arranged in the frame 110. The partition 130 is vertically arranged on the support plate 120. The support plate 120 defines two upper and lower chambers in the frame 110. The partition 130 divides the chamber above the support plate 120 into two adjacent chambers on the left and right, which are the first chamber 140 and the second chamber 150. The chamber under the support plate 120 is the third chamber 160. The first chamber 140, the second chamber 150 and the third chamber 160 are all in the shape of a cube, and the three together constitute a cube-shaped space inside the frame 110.

[0051] For example Figure 4 and Figure 5As shown, specifically, the compressor 401, the indoor heat exchanger 403 and the domestic hot water heat exchanger 404 are all located in the second chamber 150 in this embodiment, and the compressor 401 is arranged on the bottom plate of the chamber where it is located, that is, the compressor 401 is installed on the support plate 120, and the indoor heat exchanger 403 and the domestic hot water heat exchanger 404 are both arranged on the partition 130.

[0052] In some other optional embodiments, the frame 100 may also be provided in other shapes such as a hemispherical shape, a cylindrical shape, etc., and the partition plate 130 and the support plate 120 may also be provided in corresponding shape structures inside thereof.

[0053] In some other optional embodiments, the support plate 120 may not be provided, and only the partition 130 may be used to separate the space inside the frame 110, that is, the frame 110 only includes two adjacent chambers on the left and right. In this case, the compressor 401 is arranged on the bottom plate of the chamber where it is located, and the compressor 401 can be regarded as being arranged on the wall of the lower end of the frame 110.

[0054] In some other optional embodiments, the compressor 401, the indoor heat exchanger 403 and the domestic hot water heat exchanger 404 may all be disposed in the first chamber 140. One of the indoor heat exchanger 403 and the domestic hot water heat exchanger 404 may be disposed on the partition 130, and the other one may be disposed on the bottom plate of the chamber, or may be suspended in the chamber through a support structure similar to a bracket.

[0055] like Figure 1 and Figure 3 As shown, in some embodiments, the frame 110 includes a frame 111 and at least one side cover 112. The side cover 112 is detachably disposed on the frame 111, and its setting position on the frame 111 corresponds to the second chamber 150, so as to facilitate flexible disassembly and maintenance of various components inside the second chamber 150.

[0056] In this embodiment, there are three side cover plates 112 corresponding to the second chamber 150 . 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.

[0057] For example Figure 2 As shown, in some embodiments, the refrigerant circulation module 400 also includes an outdoor heat exchanger 402, which is arranged in the first chamber 140, adjacent to the compressor 401, the indoor heat exchanger 403 and the domestic hot water heat exchanger 404, and is connected thereto to form a refrigerant circulation loop for exchanging heat with the outside air to achieve heat absorption or heat release of the refrigerant.

[0058] In this embodiment, the outdoor heat exchanger 402 is a fin-type heat exchanger, which is in a plate shape and is vertically arranged on the support plate 120 .

[0059] In some other optional embodiments, the outdoor heat exchanger 402 may also be disposed in the second chamber 150 or the third chamber 160 .

[0060] In some embodiments, the heat pump system device further includes a fan module 200, and the fan module 200 and the outdoor heat exchanger 402 are arranged in the same chamber to improve the heat exchange between the outdoor heat exchanger 402 and the outside air.

[0061] In this embodiment, the outdoor heat exchanger 402 has an L-shaped horizontal cross-section and is disposed at the edge of the first chamber 140. The plane where the short side of the cross-section is located is located at the end of the first chamber 140 away from the second chamber 150, so that a roughly cubic space is left in the first chamber 140 for accommodating the fan module 200, thereby improving the space utilization of the rack 100.

[0062] Read also Figure 3 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 fan 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.

[0063] In some other optional embodiments, the number of the fans 210 can be one or more, which can be flexibly adjusted according to specific circumstances.

[0064] In some embodiments, the outer wall of the outdoor heat exchanger 402 can serve as a part of the side wall of the rack 100 , and define the inner space of the rack body 110 together with the side cover plate 112 .

[0065] In some embodiments, the support plate 120 of the first chamber 140 is provided with at least two support members 121 for supporting the outdoor heat exchanger 402 to prevent the lower end of the outdoor heat exchanger 402 from directly contacting the support plate 120. The condensed water is directly contacted with the lower end of the outdoor heat exchanger 402 and then freezes, so that the condensed water cannot be discharged, and the frozen condensed water affects the operation of the outdoor heat exchanger 402.

[0066] Specifically, there are multiple support members 121 , which are evenly distributed between the outdoor heat exchanger 402 and the support plate 120 .

[0067] In some embodiments, the support member 121 includes a gasket.

[0068] In some embodiments, the support plate 120 portion of the first chamber 140 is also provided with an ear plate, which together with the support plate 120 defines a receiving groove 122. The receiving groove 122 is formed below the outdoor heat exchanger 402 and is used to receive condensed water to prevent the condensed water from spreading over the support plate 120.

[0069] Specifically, the accommodating groove 122 is L-shaped, adapted to the shape of the outdoor heat exchanger 402 , and has a width greater than the thickness of the outdoor heat exchanger 402 .

[0070] In some embodiments, the ear plate may not be provided, and the receiving groove 122 may be formed by recessing the upper surface of the support plate 120 downward.

[0071] In some embodiments, at least one through hole is formed on the lower wall surface of the accommodating groove 122 (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.

[0072] In some embodiments, the heat pump system device also includes a water circulation module 500, which is connected to the domestic hot water heat exchanger 404 to form a water circulation loop, and performs heat exchange with the refrigerant loop formed by the refrigerant circulation module 400 to achieve heating of domestic water.

[0073] For example Figure 4 and Figure 5 As shown, specifically, the water circulation module 500 includes a water tank 501 ( Figures 1 to 5 The water tank 501 contains domestic water, and the water pump 502 is used to pump the domestic water to circulate the water in the water circulation loop.

[0074] In this embodiment, the water tank 501 is disposed in the third chamber 160, and the water pump 502 is disposed in the second chamber 150 and installed on the support plate 120 to reduce the impact of vibration on other components of the heat pump system equipment.

[0075] In some other optional embodiments, the water tank 501 may also be disposed in the first chamber 140 or the second chamber 150, or may not be disposed in the heat pump system device. The water pump 502 may also be disposed in the first chamber 140 or the third chamber 160, or may be disposed on the partition 130 of the second chamber 150.

[0076] In some embodiments, the refrigerant circulation module 400 further includes a liquid storage tank 416, which is disposed in a chamber where the compressor 401, the indoor heat exchanger 403, and the domestic hot water heat exchanger 404 are located, and is disposed on a bottom plate in the chamber.

[0077] In some embodiments, the refrigerant circulation module 400 further includes a gas-liquid separator 405 , which is disposed in a chamber where the compressor 401 , the indoor heat exchanger 403 , and the domestic hot water heat exchanger 404 are located, and is disposed on a bottom plate in the chamber.

[0078] In some embodiments, the refrigerant circulation module 400 also includes a heat exchanger 412, which can specifically be an economizer, which is arranged in the chamber where the compressor 401, the indoor heat exchanger 403 and the domestic hot water heat exchanger 404 are located, and is arranged on the partition 130 in the chamber.

[0079] In this embodiment, the liquid storage tank 416 , the gas-liquid separator 405 , and the heat exchanger 412 are all located in the second chamber 150 . The liquid storage tank 416 and the gas-liquid separator 405 are disposed on the support plate 120 , and the heat exchanger 412 is disposed on the partition 130 .

[0080] Furthermore, the heat exchanger 412, the indoor heat exchanger 403, and the domestic hot water heat exchanger 404 are arranged on the partition 130 so that the domestic hot water heat exchanger 404 is located above the heat exchanger 412, and the indoor heat exchanger 403 is located on one side of the domestic hot water heat exchanger 404 and the heat exchanger 412.

[0081] It should be understood that, in this embodiment, the indoor heat exchanger 403 is in the shape of a long plate, the domestic hot water heat exchanger 404 is a roughly cylindrical shell-and-tube heat exchanger, and the heat exchanger 412 is also in the shape of a plate, but smaller than the indoor heat exchanger 403. Therefore, the indoor heat exchanger 403 is arranged on one side of the domestic hot water heat exchanger 404 and the heat exchanger 412, which can effectively utilize the area on the partition 130, reduce the space occupied, and realize the miniaturization of the heat pump system equipment. At the same time, since the cylindrical domestic hot water heat exchanger 404 protrudes outward more, it is arranged on the top, which can better avoid other equipment and pipelines, and further improve the miniaturization of the heat pump system equipment.

[0082] In some other optional embodiments, the positions of the heat exchanger 412, the indoor heat exchanger 403, and the domestic hot water heat exchanger 404 on the partition 130 can also be adjusted according to their structural characteristics. For example, when the domestic hot water heat exchanger 404 is a plate heat exchanger and the indoor heat exchanger 403 is a shell-and-tube heat exchanger, the positions between the two can be swapped. Alternatively, the heat exchanger 412 and the domestic hot water heat exchanger 303 can be arranged to be adjacently distributed in the horizontal direction, and the indoor heat exchanger 403 is axially extended in the horizontal direction (under the premise that the width of the partition 130 allows), and is simultaneously located below or above the heat exchanger 412 and the domestic hot water heat exchanger 303.

[0083] In some other optional embodiments, the liquid storage tank 416 or the gas-liquid separator 405 may also be disposed in the first chamber 140 or the third chamber 160, or disposed on the partition 130 of the second chamber 150. The heat exchanger 412 may also be disposed in the first chamber 140 or the third chamber 160, or disposed on the support plate 120 of the second chamber 150.

[0084] In some embodiments, the heat exchanger 412, the indoor heat exchanger 403, and the domestic hot water heat exchanger 404 are arranged in the second chamber 150 at positions higher than the upper ends of the compressor 401, the liquid storage tank 416, and the gas-liquid separator 405. That is, the heat exchanger 412, the indoor heat exchanger 403, and the domestic hot water heat exchanger 404 are all located above the compressor 401, the liquid storage tank 416, and the gas-liquid separator 405, so that the space at the upper end of the second chamber 150 can be utilized, the utilization rate of the space is improved, and the miniaturization of the heat pump system equipment is realized.

[0085] In some embodiments, the heat pump system device further includes an electrical module 300 , which is disposed in the second chamber 150 and is used to control the operation of the entire heat pump system device and control the rotation of the fan module 200 .

[0086] Read also Figure 6 The refrigerant circulation module 400 further includes a first reversing valve 406, a first connecting pipeline 413, a second connecting pipeline 414 and a third connecting pipeline 415.

[0103] In some embodiments, a second flow control valve 411 is further disposed on the pipeline between the water pump 502 and the second cold water port 4043 .

[0104] It should be understood that, due to the arrangement of the first connecting pipeline 413, the second connecting pipeline 414, the third connecting pipeline 415, the second reversing valve 407 and the third reversing valve 408, the refrigerant circulation module 400 can flexibly arrange multiple circulation loops in different situations, so that the heat pump system equipment can meet the multiple functions of connecting to the terminal equipment to realize cooling and heating (such as air conditioning cooling and heating, connecting to floor heating, etc.), cooperating with the water circulation module 500 to heat domestic water, etc. The operation of the refrigerant circulation module 400 will be further described below in different situations.

[0105] 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 outdoor heat exchanger 402, and from the first refrigerant port 4021 to the fourth refrigerant port 4032 of the indoor 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.

[0106] 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 indoor heat exchanger 403, and is transmitted from the fourth refrigerant port 4032 to the outdoor 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.

[0107] 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 indoor 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).

[0108] like Fig.10 As shown, when the refrigerant circuit is connected in the summer cooling and domestic 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 domestic hot water heat exchanger 404 to be connected. The second reversing valve 407 controls the second connecting pipeline 414 to be connected.

[0109] In some embodiments, Fig.11 As shown, in the summer cooling and domestic water heating mode, a conduction mode of the refrigerant circuit is also included: the second reversing valve 407 and the third reversing valve 408 respectively control the pipeline between the compressor 401 and the fourth valve port 4064, and the first connecting pipeline 413 and the second connecting pipeline 414 are all connected. The refrigerant flows from the outlet of the compressor 401 through the third reversing valve 408 to the fourth valve port 4064 and the first connecting pipeline 413 respectively. The refrigerant flowing through the first connecting pipeline 413 passes through the domestic hot water heat exchanger 404, and flows to the fourth valve port 4064 through the second connecting pipeline 414, and then enters the outdoor heat exchanger 402 through the first valve port 4061 and the second refrigerant port 4022, and enters the indoor heat exchanger 403 through the first refrigerant port 4021 and the fourth refrigerant port 4032, and enters the first reversing valve 406 through the third refrigerant port 4031 and the third valve port 4063, and returns to the compressor 401 through the second valve port 4062 and the gas-liquid separator 405, forming a loop.

[0110] 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 domestic hot water heat exchanger 404 to be connected. The second reversing valve 407 controls the second connecting pipeline 414 to be connected. The refrigerant enters the domestic hot water 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 indoor heat exchanger 403 through the third valve port 4063 and the third refrigerant port 4031, and enters the outdoor 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.

[0111] In some embodiments, Fig.13 As shown, in the winter heating plus domestic hot water heating mode, a conduction mode of the refrigerant circuit is also included: the second reversing valve 407 and the third reversing valve 408 respectively control the pipeline between the compressor 401 and the fourth valve port 4064, and the first connecting pipeline 413 and the second connecting pipeline 414 are all connected. The refrigerant flows from the outlet of the compressor 401 through the third reversing valve 408 to the fourth valve port 4064 and the first connecting pipeline 413 respectively. The refrigerant flowing through the first connecting pipe 413 passes through the domestic hot water heat exchanger 404, and flows to the fourth valve port 4064 through the second connecting pipe 414, and enters the indoor heat exchanger 403 through the third valve port 4063 and the third refrigerant port 4031, and enters the outdoor 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.

[0112] 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 indoor heat exchanger 403 from the third valve port 4063 and the third refrigerant port 4031, and enters the outdoor 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 domestic hot water 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.

[0113] 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.

[0114] 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 domestic hot water 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 domestic hot water 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.

[0115] It should be understood that the above loop conduction condition involves the loop condition of the indoor 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 device conditions of "sky water and ground water" or "sky fluorine and ground water".

To ensure the integration degree of the heat pump system equipment, reduce the volume of the equipment, and improve the space utilization rate. 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.

[0118] The utility model also includes a second embodiment, and the main difference between this embodiment and the first embodiment is that:

[0119] 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.

[0120] 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.
