[0030] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0031] Figures 1 to 4The heat pump system device 1 in one embodiment of the utility model is shown, which can heat domestic hot water while realizing cooling and heating output to the terminal device. The heat pump system device 1 includes a housing 10, a refrigerant circulation module and a hydraulic module. Among them, the housing 10 defines a accommodating space 11, and the refrigerant circulation module and the hydraulic module are both arranged in the accommodating space 11, realizing the integration of the refrigerant circulation module and the hydraulic module. The refrigerant circulation module is used to form a refrigerant loop, exchange and transfer heat, and includes an indoor heat exchanger 40, which is used to exchange heat between the refrigerant of the refrigerant circulation module and the water of the indoor water circuit to prepare the cold water or hot water required by the terminal device. The hydraulic module is connected with the indoor heat exchanger 40 and the terminal device to form a terminal water loop for heat transfer.

[0032] Specifically, Figure 2 As shown, the hydraulic module includes a water pump 20 and an expansion tank 30, wherein the water pump 20 is used to pump the water in the terminal water circuit, and pump the water in the terminal circuit to the indoor heat exchanger 40 to form a water cycle in the terminal water circuit, or the water pump 20 is used to realize the water cycle of the terminal water circuit. The expansion tank 30 is used to buffer the pressure fluctuation in the terminal water circuit, ensure the stability of the water circuit pressure, and avoid rapid changes in pressure. Since the height of the water pump 20 and the expansion tank 30 is lower than that of other components, if they are arranged horizontally, the space from the upper end of the two to the upper end of other components is vacated, and the horizontal space is also occupied due to the horizontal arrangement of the water pump 20 and the expansion tank 30. The water pump 20 and the expansion tank 30 are arranged in the vertical direction in the accommodating space 11, which effectively utilizes the space generated by the height difference between the water pump 20 and the expansion tank 30 and other components, while reducing the occupation of the horizontal space, improving the utilization rate of the space, and thus realizing the miniaturization of the heat pump system device 1.

[0033] In some embodiments, since the water pump 20 vibrates during operation and pipes need to be connected to the upper and lower sides of the water pump 20, the water pump 20 is arranged above the expansion tank 30 to avoid the vibration of the water pump 20 during operation from affecting the outer shell 10 and other equipment connected to the outer shell 10, reducing the resonance of the heat pump system equipment 1, and facilitating the connection and assembly of pipes, reducing space occupancy, and achieving miniaturization.

[0034] In some other optional embodiments, the expansion tank 30 may also be disposed above the water pump 20 .

[0035] Specifically, Figure 3 and Figure 4As shown, the water pump 20 includes a pump body 21 and a water pump bracket 22. The water pump bracket 22 is disposed on the housing 10 and defines a clearance space, and the expansion tank 30 is disposed in the clearance space. The pump body 21 is fixed above the expansion tank 30 through the water pump bracket 22. By connecting the water pump bracket 22 between the housing 10 and the pump body 21, the vibration intensity of the pump body 21 can be buffered and the impact on other components can be reduced.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, the housing 10 is in a cubic shape, and its accommodating space 11 is also in a cubic shape. The housing 10 includes a rectangular bottom plate 12, and the expansion tank 30 and the water pump 20 are both installed on the bottom plate 12. The water pump bracket 22 is arranged in an L shape, and the end of the long side of the L shape is connected to the housing 10, and the short side of the L shape is arranged horizontally in the air, that is, the L shape is inverted on the bottom plate 12, the long side of the L shape is perpendicular to the bottom plate 12, and the short side of the L shape is parallel to the bottom plate 12. The pump body 21 is installed on the short side of the L shape, and the space defined between the long side and the short side of the L shape is the clearance space.

[0037] In some other optional embodiments, the water pump bracket 22 can also be arranged in other structures such as a "J" shape, a sideways concave shape, etc. When the water pump bracket 22 is in a "J" shape, both ends of the "J" shape can be connected to the bottom plate 12, and the expansion tank 30 is arranged between the "J"-shaped water pump bracket 22 and the bottom plate 12.

[0038] For example Figure 3 and Figure 4 As shown, in some embodiments, the expansion tank 30 includes a tank body 31 and a stopper 32. The stopper 32 is disposed on the housing 10 and defines a stopper space, so that the expansion tank 30 is limited in the stopper space and then fixed on the housing 10, so as to prevent the expansion tank 30 from moving in the housing 10 during the process of moving the heat pump system device 1.

[0039] In this embodiment, the tank body 31 is cylindrical, and the limiting member 32 is roughly in the shape of a "X"; its two ends are respectively connected to the bottom plate 12, and the remaining portion is arched, fitting with most of the circumferential contour of the tank body 31, thereby limiting the tank body 31 between the limiting space defined by the limiting member 32 and the bottom plate 12.

[0040] In some other optional embodiments, the tank body 31 may also be directly fixed to the bottom plate 12 by welding or the like, without providing the limiting member 32 .

[0041] In some embodiments, the indoor heat exchanger 40 is plate-shaped and vertically arranged on one side of the water pump 20 and the expansion tank 30. Thus, the upper end of the indoor heat exchanger 40 and the upper end of the water pump 20 are roughly in a relatively consistent position, thereby saving the increase in horizontal space occupied by the water pump 20 and the expansion tank 30 caused by the horizontal arrangement of the water pump 20 and the expansion tank 30, and the waste of space above the water pump 20 and the expansion tank 30.

[0042] Specifically, the indoor heat exchanger 40 includes an indoor heat exchanger body 41 and a heat exchanger bracket 42. The heat exchanger bracket 42 is disposed on the housing 10, and the indoor heat exchanger body 41 is mounted on the heat exchanger bracket 42, thereby reducing the influence of vibration of the indoor heat exchanger body 41 during operation on other components.

[0043] In this embodiment, the indoor heat exchanger body 41 and the heat exchanger bracket 42 are both in a cubic shape, and the heat exchanger bracket 42 is installed on the bottom plate 12, so that the indoor heat exchanger body 41 is erected on the bottom plate 12. And the height of the heat exchanger bracket 42 is such that the pipes connected to the indoor heat exchanger body 41 are all located above the expansion tank 30, so as to avoid the pipes from bypassing the expansion tank 30 or adjusting the height position of the expansion tank 30 during the process of connecting with the indoor heat exchanger body 41. The height limitation of the heat exchanger bracket 42 can further improve the utilization rate of the space, make a reasonable layout, and realize the miniaturization of the heat pump system device 1.

[0044] Read also Figure 2 ( Figure 2 The internal structure distribution diagram of the body-shaped shell 10 below this embodiment is shown after hiding one of the side walls), specifically, the indoor heat exchanger 40 is arranged adjacent to a portion of the side wall of the shell 10 (the other side wall opposite to the hidden side wall), the water pump 20 and the expansion tank 30 are arranged on one side of the indoor heat exchanger 40, and are clamped between the indoor heat exchanger 40 and the other portion of the side wall of the shell 10 (the hidden side wall).

[0045] like Figure 2 As shown, in some embodiments, the refrigerant circulation module further includes an outdoor heat exchanger 50, which is disposed above the indoor heat exchanger 40, the water pump 20 and the expansion tank 30 through a partition, and is used to perform heat exchange between the refrigerant and the outside air to achieve heat absorption or heat release of the refrigerant. The outdoor heat exchanger 50 is connected to the indoor heat exchanger 40 through a refrigerant pipeline.

[0046] Specifically, the partition includes a chassis and legs. The chassis is used to receive water generated by heat exchange of the outdoor heat exchanger 50, and supports the outdoor heat exchanger 50 to separate the outdoor heat exchanger 50 from other components. The legs are used to support the chassis, and the chassis is suspended and horizontally arranged in the accommodating space 11, so as to separate the accommodating space 11 into upper and lower parts.

[0047] In this embodiment, the chassis is rectangular, the number of the legs is four, the upper ends are connected to the four corners of the chassis respectively, and the lower ends are connected to the bottom plate 12. The indoor heat exchanger 40, the water pump 20 and the expansion tank 30 are all arranged in the cubic space defined by the bottom plate 12, the chassis, part of the side wall of the shell 10 and the four legs, and the indoor heat exchanger 40 is located on one side of the cubic space and is adjacent to the side wall of the part of the shell 10 defining the cubic space, and the water pump 20 and the expansion tank 30 are located on the side of the indoor heat exchanger 40 away from the side wall of the shell 10 adjacent to it, and are located between the indoor heat exchanger 40 and another part of the side wall of the shell 10.

[0048] In some other optional embodiments, the chassis may also be provided in other shapes such as polygonal, elliptical, irregular, etc., so as to support the outdoor heat exchanger 50 .

[0049] The indoor heat exchanger 40 is connected to the outdoor heat exchanger 50 through a refrigerant pipe. The indoor heat exchanger 40 has four ports, two ports are connected to the refrigerant pipe, and the other two ports are respectively connected to the input end and the output end of the terminal device. The water pump 20 and the expansion tank 30 are connected between the indoor heat exchanger 40 and the terminal device.

[0050] Specifically, the two ports of the indoor heat exchanger 40 connected to the input end and the output end of the terminal device are defined as an input port and an output port, respectively. The input port is connected to the output end of the terminal device through a first refrigerant pipe 43, and the output port is connected to the input end of the terminal device through a second refrigerant pipe 44. Figure 5 As shown, the first refrigerant pipe 43 includes two pipe sections, and the input end and the output end of the water pump 20 are respectively connected to the two pipe sections of the first refrigerant pipe 43, and then arranged between the terminal device and the indoor heat exchanger 40, and the water of the terminal device is pumped into the indoor heat exchanger 40 through the first refrigerant pipe 43, and after heat exchange, it flows back to the terminal device through the second refrigerant pipe 44. One end of the first refrigerant pipe 43 and the second refrigerant pipe 44 respectively extends to the shell shell 10, for connecting with the terminal equipment. The port of the expansion tank 30 is connected to the terminal water circuit through a separate pipeline, and the connection position with the terminal water circuit can be located at the shell shell 10, or may be located in the housing shell 10 outside.

[0051] In some embodiments, the heat pump system equipment also includes a water tank 60, which is vertically arranged on one side of the outdoor heat exchanger 50, located diagonally above the water pump 20 and the expansion tank 30, and is separated from the outdoor heat exchanger 50 by a plate-shaped spacer.

[0052] Specifically, the lower end of the spacer is connected to one end of the chassis, so that the accommodating space 11 is divided into an L-shaped chamber and a rectangular chamber. The outdoor heat exchanger 50 is arranged in the rectangular chamber. The water tank 60 is arranged at the vertical long side of the L-shaped chamber. The water pump 20, the expansion tank 30, the indoor heat exchanger 40 and other components of the refrigerant circulation module are all arranged at the horizontal short side of the L-shaped chamber, and the water pump 20, the expansion tank 30 and the indoor heat exchanger 40 are all located at the position corresponding to the rectangular chamber at the short side of the L-shaped chamber.

[0053] In some embodiments, the refrigerant circulation module also includes a fan, which is arranged in a rectangular chamber. The horizontal cross-section of the outdoor heat exchanger 50 is L-shaped. The fan is arranged in the space enclosed by the L-shape to enhance the heat exchange between the outdoor heat exchanger 50 and the outside air.

[0054] In some embodiments, the refrigerant circulation module also includes a water tank pump, a domestic hot water heat exchanger, a compressor, a four-way valve, an electric control box, a liquid storage tank, a gas-liquid separator, a three-way valve, an expansion valve and other components (not shown in the figure), which are all arranged at the horizontal short side of the L-shaped chamber. Among them, the compressor, the outdoor heat exchanger 50, the indoor heat exchanger 40, the gas-liquid separator, the liquid storage tank and other components together constitute a refrigerant circulation loop acting on the terminal device, and the indoor heat exchanger 40 and the hydraulic module act on the terminal device to achieve cooling and heating of the terminal device. The compressor, the domestic hot water heat exchanger, the outdoor heat exchanger 50, the indoor heat exchanger, the gas-liquid separator, the liquid storage tank and other components together constitute a refrigerant circulation loop acting on the terminal device and the water tank 60, while cooling and heating the terminal device, the domestic hot water in the water tank 60 is heated. The compressor, domestic hot water heat exchanger, outdoor heat exchanger 50, gas-liquid separator, liquid storage tank and other components together constitute a refrigerant circulation loop acting on the water tank 60, realizing a separate domestic hot water heating function. The water tank 60, the water tank water pump and the domestic hot water heat exchanger constitute a domestic hot water loop, which performs heat exchange with the refrigerant circulation loop acting on the terminal device and the water tank 60 to realize domestic hot water heating. The valve bodies such as the three-way valve, the four-way valve, and the expansion valve are arranged on the pipelines between the various components to improve the utilization rate of the pipelines and save the number and length of the pipelines. The electric control box is used to control the operation of the entire heat pump system device 1.

[0055] In addition to integrating the hydraulic module into the heat pump system device 1, the module equipment involved in the domestic hot water circuit is also integrated into the heat pump system device 1 to realize functions such as cooling, heating, and heating domestic hot water. There is no need to additionally equip separate hydraulic modules, domestic hot water modules and other equipment to match them, which improves the integration of the equipment, reduces the complexity of installation and coordination between multiple devices during the installation process, improves installation efficiency, and enhances user experience.

[0056] Specifically, the heat pump system equipment 1 can realize multiple modes of operation, such as terminal cooling and domestic hot water heating mode (including full heat recovery mode and partial heat recovery mode), terminal heating and domestic hot water mode, separate domestic hot water mode, separate heating mode and separate cooling mode.

[0057] When the heat pump system device 1 is in the terminal cooling and domestic hot water mode, the full heat recovery mode can be used at the beginning. The compressor, domestic hot water heat exchanger, indoor heat exchanger, gas-liquid separator, liquid storage tank and other components form a loop, and all the heat of the high-temperature refrigerant is converted into heat at the domestic hot water heat exchanger, and the heat originally used for heat exchange with the air is all used to prepare domestic hot water, and the outdoor heat exchanger 50 does not need to start heat exchange. That is, all the refrigerants undergo phase change at the domestic hot water heat exchanger, condensing from gas to liquid, releasing heat, and then entering the liquid storage tank, and then reaching the indoor heat exchanger through the expansion valve, and exchanging heat with the terminal equipment through the hydraulic module to absorb heat, so as to achieve the effect of refrigeration, and finally the refrigerant enters the domestic hot water heat exchanger through the compressor to realize circulation.

[0058] When the heat pump system device 1 is in the terminal cooling and domestic hot water mode, and the domestic hot water has been heated to a certain temperature, it can be switched to a partial heat recovery mode. At this time, the compressor, domestic hot water heat exchanger, indoor heat exchanger, outdoor heat exchanger 50, gas-liquid separator, liquid storage tank and other components form a loop. The high-temperature refrigerant first passes through the domestic hot water heat exchanger to exchange part of the heat with the domestic hot water loop, and then passes through the outdoor heat exchanger 50 to exchange the remaining heat with the outside air for release. Then it reaches the indoor heat exchanger through the liquid storage tank, and absorbs heat through the hydraulic module with the terminal device to achieve the cooling effect. Finally, the refrigerant enters the domestic hot water heat exchanger through the compressor to realize circulation.

[0059] When the heat pump system device 1 is in the heating and domestic hot water mode, the compressor, domestic hot water heat exchanger, indoor heat exchanger, outdoor heat exchanger 50, gas-liquid separator, liquid storage tank and other components form a loop. The high-temperature refrigerant passes through the domestic hot water heat exchanger, exchanges part of the heat with the water in the domestic hot water loop, and then passes through the indoor heat exchanger to exchange the remaining heat with the water in the terminal device through the hydraulic module, so as to achieve the effect of releasing heat for heating. The refrigerant after heat exchange then passes through the liquid storage tank and the outdoor heat exchanger 50 in turn, absorbs heat by heat exchange with the outside air, and finally returns to the compressor and enters the domestic hot water heat exchanger to realize circulation.

[0060] When the heat pump system device 1 is in the single domestic hot water mode, the compressor, domestic hot water heat exchanger, outdoor heat exchanger 50, gas-liquid separator, liquid storage tank and other components form a loop. All the heat of the high-temperature refrigerant first exchanges heat with the water in the domestic hot water loop through the domestic hot water heat exchanger to heat the water, then reaches the outdoor heat exchanger 50 through the liquid storage tank, exchanges heat with the outside air to absorb heat, and finally enters the domestic hot water heat exchanger through the gas-liquid separator and compressor to achieve circulation.

[0061] When the heat pump system device 1 is in a single cooling mode, the compressor, outdoor heat exchanger 50, indoor heat exchanger, gas-liquid separator, liquid storage tank and other components form a loop. The high-temperature refrigerant first enters the outdoor heat exchanger 50 to exchange heat with the outside air to release heat, then enters the indoor heat exchanger through the liquid storage tank, and absorbs heat through the water exchange with the terminal device through the hydraulic module to achieve the cooling effect of the terminal device. Finally, it passes through the gas-liquid separator and the compressor in turn, and enters the outdoor heat exchanger 50 to realize the circulation.

[0062] When the heat pump system device 1 is in a single heating mode, the high-temperature refrigerant first enters the indoor heat exchanger, exchanges heat with the terminal device through the hydraulic module, releases heat to achieve the heating effect, and then enters the outdoor heat exchanger 50 through the liquid storage tank, exchanges heat with the outside air to absorb heat, and finally enters the indoor heat exchanger again through the gas-liquid separator and the compressor to realize circulation.

[0063] It should be understood that in this embodiment, the water pump bracket 22, the stopper 32 and the heat exchanger bracket 42 are connected to the bottom plate 12 by bolts (screws), and the lower end of the spacer is also connected to one end of the chassis by bolts. In other optional embodiments, it can also be connected by other methods such as welding and integral molding.

[0064] 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.
