Description

Technical Field

[0001] The utility model relates to the technical field of air energy heat pumps, in particular to a heat pump system device. Background Art

[0002] A heat pump is a device that uses the principle of heat transfer to transfer heat from a low-temperature heat source to a high-temperature heat source. Driven by electricity, a heat pump can obtain heat from the air and apply it to indoor terminal equipment, such as fan coil units, floor heating and other equipment for heating. Thus, one unit of electricity can absorb two to three units of free heat from the outdoor environment, and then use this heat to heat water and apply it to the terminal equipment.

[0003] Existing heat pumps are mainly used to prepare hot water. Therefore, a plate heat exchanger or a hot water jacket heat exchanger is usually set in the heat pump host as a condenser to prepare hot water, and is fixed to the outer casing of the heat pump through inlet and outlet pipes to form water inlets and outlets. The external inlet and outlet pipes will be connected to the inlet and outlet of the heat pump shell to enable the hot water prepared by the heat pump host to be output to water tanks, terminals and other equipment.

[0004] However, in existing designs, due to differences in design or assembly, there will be certain installation and welding deviations in the water inlet and outlet pipes and the water inlets and outlets. As a result, in subsequent installation, it is difficult to fix the external water pipes to the water inlet and outlet pipes in the heat pump main unit, resulting in installation difficulties and time-consuming and labor-intensive.

Therefore, the features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0029] 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.

[0030] Figures 1 to 4A heat pump system device 1 in an embodiment of the utility model is shown, comprising a housing 10, a refrigerant circulation module and a pipe limit assembly 30. The housing 10 defines an accommodating space 11, and the refrigerant circulation module is arranged in the accommodating space 11. The refrigerant circulation module comprises an indoor heat exchanger 20, which is used to communicate with the terminal device to form a terminal loop, and the terminal loop performs heat exchange with the indoor heat exchanger 20 of the refrigerant circulation module and the refrigerant loop formed by other components to achieve cooling or heating. The pipe limit assembly 30 is used to limit the connecting pipe between the indoor heat exchanger 20 and the terminal device, so as to facilitate the rapid assembly of the heat pump system device 1.

[0031] Specifically, Figure 2 and Figure 4 As shown, a water inlet 12 and a water outlet 13 are formed on the wall of the shell 10, which can respectively connect the accommodating space 11 with the outside. The indoor heat exchanger 20 includes an indoor heat exchanger body 21, a water inlet connecting pipe 22 and a water outlet connecting pipe 23. The first ends of the water inlet connecting pipe 22 and the water outlet connecting pipe 23 are respectively connected to the two water inlet and outlet ports of the indoor heat exchanger body 21. The free end of the water inlet connecting pipe 22 (i.e., the second end opposite to the first end thereof) is arranged corresponding to the water inlet 12, and the free end of the water outlet connecting pipe 23 (the second end opposite to the first end thereof) is arranged corresponding to the water outlet 13. The free ends of the two are connected to the connecting pipes of the terminal equipment through the water inlet 12 and the water outlet 13, respectively.

[0032] The pipeline limit assembly 30 includes at least one limit member, which is arranged on the shell 10, and is used to limit the displacement of the free end of the water inlet connecting pipe 22 away from the water inlet 12, so that the free end of the water inlet connecting pipe 22 corresponds to the water inlet 12, and limit the displacement of the free end of the water outlet connecting pipe 23 away from the water outlet 13, so that the free end of the water outlet connecting pipe 23 corresponds to the water outlet 13.

[0033] It should be understood that, in the process of installing the heat pump system equipment 1, due to the manufacturing size errors of various components, the installation errors between components, and the deformation errors caused by the self-weight of each component, it is easy to cause the installation holes to not correspond, the pipes and the connection ports to not correspond, etc. in the later steps of the installation. The setting of the limiter allows the free end positions of the water inlet connecting pipe 22 and the water outlet connecting pipe 23 to be limited by the limiter before the accommodating space 11 of the shell 10 is closed (that is, after the various components in the accommodating space 11 are installed in place, and before the accommodating space 11 is isolated from the outside by snapping on a side wall of the shell 10), so that the positions of the ends are first limited to the positions corresponding to the water inlet 12 and the water outlet 13, so as to realize the pre-installation of the water inlet connecting pipe 22 and the water outlet connecting pipe 23. Furthermore, when the last wall of the housing 10 is fastened, it is not necessary to consider the docking of the water inlet connecting pipe 22 with the water inlet 12 and the docking of the water outlet connecting pipe 23 with the water outlet 13. It is only necessary to simply dock the wall of the housing 10 with the other wall to directly achieve the correspondence between the water inlet 12 and the water inlet connecting pipe 22 and the correspondence between the water outlet 13 and the water outlet connecting pipe 23. That is, through the early shaping and positioning effect, the free end openings of the water inlet connecting pipe 22 and the water outlet connecting pipe 23 are not displaced during the installation process, which is convenient for later installation and debugging. Therefore, there is no need to align the wall with other walls of the shell 10 when finally fastening the shell 10. At the same time, it is necessary to consider the alignment connection between the water inlet 12 and the water outlet 13 and the water inlet connecting pipe 22 and the water outlet connecting pipe 23. This will make it difficult to achieve direct docking of several of them at the same time, resulting in low installation efficiency. In addition, it is easy to bend the water inlet connecting pipe 22 and the water outlet connecting pipe 23 during the installation process, generating unnecessary stress and causing displacement and damage of the pipeline.

[0034] like Figure 4 As shown, in some embodiments, the limiting member is provided in a plate shape. At least one pre-installed hole is formed along the thickness direction, the pre-installed hole is coaxially arranged with the water inlet and / or the water outlet, and the free ends of the water inlet connecting pipe 22 and the water outlet connecting pipe 23 are respectively passed through the pre-installed hole. By setting the pre-installed hole, the position of the free ends of the water inlet connecting pipe 22 and the water outlet connecting pipe 23 is limited.

[0035] Specifically, there are two limit members, namely, a first limit plate 31 and a second limit plate 32. The first limit plate 31 is formed with a first pre-installed hole corresponding to the water inlet 12, and the free end of the water inlet connecting pipe 22 is inserted into the first pre-installed hole. The second limit plate 32 is formed with a second pre-installed hole corresponding to the water outlet 13, and the free end of the water outlet connecting pipe 23 is inserted into the second pre-installed hole.

[0036] In some other optional embodiments, the limiting member may not be set to a plate shape, but may be set to a rod-shaped structure with an annular limiting structure at one end, and the other end of the rod-shaped structure may be fixed to the shell 10 to achieve the limiting operation.

[0037] In some other optional embodiments, the number of the plate-like limiting member can also be set to one, by forming two pre-installed holes on the plate-like limiting member, so that the water inlet connecting pipe 22 and the water outlet connecting pipe 23 are respectively passed through the two pre-installed holes, thereby achieving limitation of both.

[0038] In some other optional embodiments, when the number of the plate-shaped limiting member is one, the number of its pre-installed holes can also be set to one, so that the free ends of the water inlet connecting pipe 22 and the water outlet connecting pipe 23 are both inserted into the pre-installed hole.

[0039] In some embodiments, the shell 10 further includes a bottom plate 14 , the indoor heat exchanger 20 , the first limiting plate 31 and the second limiting plate 32 are vertically arranged on the bottom plate 14 , and the water inlet 12 and the water outlet 13 are formed on the side wall of the shell 10 .

[0040] like Figure 2 and Figure 3 As shown, in this embodiment, the housing 10 is in a cubic shape, so that the accommodating space 11 is also in a cubic shape. The bottom plate 14 is rectangular, and the first limiting plate 31 and the second limiting plate 32 are both rectangular, and the first limiting plate 31 and the second limiting plate 32 are parallel to the side wall of the housing 10 where the water inlet 12 and the water outlet 13 are located, and are perpendicular to the bottom plate 14. The height of the first limiting plate 31 is lower than the second limiting plate 32, so that the height of the second pre-installed hole is higher than the first pre-installed hole, and then the height of the corresponding water outlet 13 is higher than the height of the water inlet 12. So as to facilitate the installation of the water inlet connecting pipe 22 and the water outlet connecting pipe 23.

[0041] In this embodiment, after the first limiting plate 31 and the second limiting plate 32 are installed on the bottom plate 14, an "L" shape is formed, and the first pre-installed hole and the second pre-installed hole are respectively located on two sides of the "L" shape.

[0042] In some other optional embodiments, the shell 10 can also be in other shapes such as columnar, semicircular, etc. The first limiting plate 31 and the second limiting plate 32 can also be in other shapes such as polygonal, elliptical, circular, etc. The first limiting plate 31 and the second limiting plate 32 may not be parallel to the side wall of the shell 10 where the water inlet 12 and the water outlet 13 are located. It is only necessary to ensure that the free ends of the water inlet connecting pipe 22 and the water outlet connecting pipe 23 are respectively connected to the water inlet 12 and the water outlet 13. The height of the first limiting plate 31 can also be higher than the second limiting plate 32. The height of the first pre-installed hole can also be higher than the second pre-installed hole. The height of the first limiting plate 31 and the second limiting plate 32 can also be level. The height of the first pre-installed hole and the second pre-installed hole can also be level.

[0043] In some embodiments, the free end of the water inlet connecting pipe 22 is circumferentially limited in the first pre-installed hole, and the free end of the water outlet connecting pipe 23 is circumferentially limited in the second pre-installed hole. In the process of connecting with the connecting pipe of the external equipment, the connection of the pipe will not be twisted in the circumferential direction, causing the pipe to deform, thereby increasing the firmness of the pipe assembly and improving its service life.

[0044] Specifically, Figure 4 As shown, the pipeline limit assembly 30 also includes a first joint 33 and a second joint 34. The water inlet connecting pipe 22 is circumferentially limited in the first pre-installed hole through the first joint 33. The water outlet connecting pipe 23 is circumferentially limited in the second pre-installed hole through the second joint 34. The first joint 33 and the second joint 34 are both short tubular arrangements, and their outer contours are both polygonal arrangements (it should be understood that this means that the outer contour of the cross section perpendicular to the tubular axis is polygonal). The first joint 33 is inserted into the first pre-installed hole, and the shape of the first pre-installed hole is adapted to the outer contour of the first joint 33, and the shape of the second pre-installed hole is adapted to the outer contour of the second joint 34.

[0045] In this embodiment, the cross-sectional shapes of the first joint 33 and the second joint 34 perpendicular to their axes are both regular hexagons, and the shapes of the first pre-installed hole and the second pre-installed hole are also regular hexagons corresponding thereto. The axes of the first joint 33 and the second joint 34 are both parallel to the bottom plate 14 and perpendicular to the side wall of the housing 10 where the water inlet 12 and the water outlet 13 are located.

[0046] In some other optional embodiments, the cross-sectional shapes of the first joint 33 and the second joint 34 may also be other polygonal structures such as triangles, rectangles, pentagons, or other irregular shapes such as ellipses. The shapes of the first joint 33 and the second joint 34 may be the same or different.

[0047] In some other optional embodiments, the first joint 33 and the second joint 34 may not be provided. By changing the cross-sectional shape of the free ends of the water inlet connecting pipe 22 and the water outlet connecting pipe 23 (such as polygonal, irregular, or other shapes that are not prone to circumferential relative rotation), and setting the shapes of the first pre-installed hole and the second pre-installed hole to correspond to the free ends of the water inlet connecting pipe 22 and the water outlet connecting pipe 23, it is also possible to prevent circumferential relative rotation and avoid twisting of the pipe.

[0048] In some embodiments, the first end of the first joint 33 is connected to the free end of the water inlet connecting pipe 22, and the second end is formed with a thread for connecting to the connecting pipe of the terminal device. The first end of the second joint 34 is connected to the free end of the water outlet connecting pipe 23, and the second end is also formed with a thread for connecting to another connecting pipe of the terminal device. When docking the terminal device, it is only necessary to rotate the connecting pipe with the first joint 33 and the second joint 34 by threaded connection to achieve docking, which is convenient and quick to operate.

[0049] It should be understood that the threads on the second ends of the first connector 33 and the second connector 34 can be formed on the inner surface or the outer surface, and can correspond to the connecting pipe of the terminal device, which is not limited here.

[0050] In some embodiments, the first joint 33 and the second joint 34 are both disposed in the accommodation space 11. The first joint 33 includes a first tubular body 331 and at least one first connecting lug 332, and at least one first connecting hole 3321 is formed on the first connecting lug 332. The second joint 34 includes a second tubular body 341 and at least one second connecting lug 342, and at least one second connecting hole 3421 is formed on the second connecting lug 342. Figure 2 At least two positioning holes 15 are also formed on the shell 10, corresponding to at least one first connecting hole 3321 and at least one second connecting hole 3421 respectively, for achieving relative fixation of the first joint 33 and the second joint 34 with the shell 10 by passing bolts through the first connecting hole 3321 (or the second connecting hole 3421) and the positioning hole 15 respectively.

[0051] It should be understood that, during the manufacturing process, the sizes of the first limit plate 31 and the second limit plate 32 and the positions of the first pre-installed holes and the second pre-installed holes are relatively fixed to ensure that they correspond to the positions of the water inlet 12 and the water outlet 13 during the installation process. In addition, during the assembly process, it is only necessary to fix it on the shell 10 to achieve the assembly, so there are fewer parts and operation steps that cause errors, making it easier for the first joint 33 and the second joint 34 installed on the first limit plate 31 and the second limit plate 32 to correspond to the water inlet 12 and the water outlet 13. The first joint 33 and the second joint 34 are both arranged in the accommodating space, so that during the assembly process, the side wall of the last shell 10 can be directly buckled onto the other side walls.

[0052] For example Figure 4 As shown, in this embodiment, the number of the first connecting lug plates 332 and the second connecting lug plates 342 are both two, and they are respectively arranged at the second ends of the first tubular body 331 and the second tubular body 341, and are arranged parallel to or adjacent to the side wall of the housing 10 where the water inlet 12 and the water outlet 13 are located. The two first connecting lug plates 332 are respectively arranged at two opposite sides of the second end of the first tubular body 331, and each of the first connecting lug plates 332 is provided with a first connecting hole 3321. The two second connecting lug plates 342 are respectively arranged at two opposite sides of the second end of the second tubular body 341, and each of the second connecting lug plates 342 is provided with a second connecting hole 3421. Four positioning holes 15 are correspondingly arranged, corresponding to the two first connecting holes 3321 and the two second connecting holes 3421, respectively.

[0053] In some other optional embodiments, two, three or more connection holes may be provided on each of the first connection ear plate 332 and the second connection ear plate 342. The number of the first connection ear plate 332 and the second connection ear plate 342 may also be different, such as the first connection ear plate 332 may be provided as one, three or more, and / or the second connection ear plate 342 may be provided as one, three or more.

[0054] In some embodiments, the first limiting plate 31 and the second limiting plate 32 are also respectively provided with through holes corresponding to the first connecting hole 3321 and the second connecting hole 3421, so that during the bolt connection process, the bolts can be simultaneously passed through the positioning hole 15, the first connecting hole 3321 (or the second connecting hole 3421) and the through hole, further strengthening the connection relationship between the shell 10, the water inlet connecting pipe 22 (or the water outlet connecting pipe 23) and the pipeline limiting assembly 30.

[0055] For example Figure 3As shown, in some embodiments, the refrigerant circulation module also includes an outdoor heat exchanger 40 and a domestic hot water heat exchanger, and the heat pump system device 1 also includes a water tank (not shown in the figure). The outdoor heat exchanger 40 is connected to the domestic hot water heat exchanger (and the indoor heat exchanger 20) to form a refrigerant circulation loop, and the domestic hot water heat exchanger is connected to the water tank to form a domestic hot water loop. Heat exchange is performed between the two loops, so that the heat pump system device 1 can achieve cooling and heating of the terminal device while also achieving heating of domestic hot water. The outdoor heat exchanger 40 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 40 is connected to the indoor heat exchanger 20. The water tank is used to accommodate and output domestic hot water. The domestic hot water heat exchanger is used to perform heat exchange between the domestic hot water to be heated and the refrigerant to heat the domestic hot water.

[0056] Specifically, the outdoor heat exchanger 40 is arranged above the indoor heat exchanger 20 through a water receiving pan, and the water tank is vertically arranged on one side of the outdoor heat exchanger 40, and is spaced apart from the outdoor heat exchanger 40 by a vertical partition. The lower end of the water tank is also suspended by a supporting structure, so that the water tank is spaced apart from the bottom plate 14. One end of the water receiving pan is connected to the lower end of the plate-shaped partition, so that the cubic accommodating space 11 is divided into an L-shaped chamber and a rectangular chamber. The outdoor heat exchanger 40 is arranged in the rectangular chamber. The water tank is arranged at the vertical long side of the L-shaped chamber and is located obliquely above the indoor heat exchanger 20. The indoor heat exchanger 20 and the domestic hot water heat exchanger are both arranged at the short side of the L-shaped chamber.

[0057] 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 40 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 40 and the outside air.

[0058] In some embodiments, the heat pump system device 1 further includes a hydraulic module, which is disposed in the accommodating space 11 and includes a water pump and an expansion tank (not shown in the figure), which are both connected to the indoor heat exchanger 20 and the terminal device to form a terminal water loop for heat transfer. The water pump is used to pump water in the terminal water loop to achieve circulation. The expansion tank is used to stabilize the water pressure in the terminal water loop.

[0059] In some embodiments, the refrigerant circulation module further includes a water tank pump, 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 together with the water pump, the expansion tank and the like are arranged at the horizontal short side of the L-shaped chamber, making full use of the space below the water tank and the outdoor heat exchanger 40. In addition, the domestic hot water heat exchanger and the water tank pump are both located below the water tank, making full use of the space at the lower end of the water tank, and realizing the integration and miniaturization of the equipment.

[0060] Among them, the compressor, outdoor heat exchanger 40, indoor heat exchanger 20, gas-liquid separator, liquid storage tank and other components together constitute a refrigerant circulation loop acting on the terminal device, and act on the terminal device through the indoor heat exchanger 20 and the hydraulic module to achieve cooling and heating of the terminal device. The compressor, domestic hot water heat exchanger, outdoor heat exchanger 40, indoor heat exchanger, gas-liquid separator, liquid storage tank and other components together constitute a refrigerant circulation loop acting on the terminal device and the water tank, while cooling and heating the terminal device, the domestic hot water in the water tank is heated. The compressor, domestic hot water heat exchanger, outdoor heat exchanger 40, gas-liquid separator, liquid storage tank and other components together constitute a refrigerant circulation loop acting on the water tank, realizing a separate domestic hot water heating function. The water tank, water tank water pump and 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 to achieve heating of domestic hot water. The valve bodies such as the three-way valve, the four-way valve, the expansion valve, etc. 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.

[0061] The heat pump system device 1 can realize functions such as cooling, heating, and heating domestic hot water at the same time, without the need for additional equipment such as separate hydraulic modules and domestic hot water modules to match it, thereby improving the integration of the equipment, reducing the complexity of installation and coordination between multiple devices during the installation process, improving installation efficiency, and enhancing user experience.

[0062] 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.

[0063] 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 40 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, achieving the effect of refrigeration, and finally the refrigerant enters the domestic hot water heat exchanger through the compressor to realize circulation.

[0064] 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 40, 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 40 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.

[0065] 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 40, 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 40 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.

[0066] 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 40, 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 40 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.

[0067] When the heat pump system device 1 is in a single cooling mode, the compressor, outdoor heat exchanger 40, 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 40 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 40 to realize the circulation.

[0068] 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 40 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.
