Detailed Implementation

[0036] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0037] In this utility model, when directions (up, down, left, right, front, and back) are described, it is only for the convenience of describing the technical solution of this utility model, and does not indicate or imply that the technical features referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0038] In this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the stated number; "above," "below," "within," etc. are understood to include the stated number. In the description of this utility model, if "first" or "second" is used, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0039] In this utility model, unless otherwise explicitly defined, terms such as "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0040] See Figure 1 , Figure 2 , Figure 3 and Figure 8 This utility model provides a heat pump unit, the heat pump assembly being installed in indoor settings such as large shopping malls, factories, or common areas of residences. The heat pump unit includes a housing 1, a heat pump assembly, and a fan 2. The housing 1 has a partition 12 that divides the inner cavity of the housing 1 into a first mounting cavity 111 and a second mounting cavity 112, with the first mounting cavity 111 located above the second mounting cavity 112. The left and / or right sides of the housing 1 have air inlets communicating with the first mounting cavity 111. Figure 8 The housing 1 is provided with an air outlet 13 that communicates with the first mounting cavity 111.

[0041] The heat pump assembly includes a compressor 31, a first heat exchange assembly, a throttling element, and a second heat exchange assembly, all connected in a closed loop by refrigerant piping 4. The compressor 31 and the second heat exchange assembly are located within a second mounting cavity 112, while the first heat exchange assembly is located within a first mounting cavity 111. The refrigerant piping 4 passes through a partition 12 and connects to the first heat exchange assembly in the first mounting cavity 111 and the compressor 31 and the second heat exchange assembly in the second mounting cavity 112. This layout creates a modular design, facilitating installation and reducing installation and maintenance costs.

[0042] The first heat exchange assembly includes two first heat exchangers 321 spaced apart in the front-to-back direction. The two first heat exchangers 321 are connected in parallel by a pipe. Two sealing plates 322 are spaced apart between the two first heat exchangers 321 in the left-to-right direction to enclose an exhaust space 323. The housing 1 is provided with vents 324 between the partition plate 12 and the first heat exchangers 321, and between the partition plate 12 and the sealing plates 322. That is, the vents 324 are located around the bottom of the exhaust space 323.

[0043] The fan 2 is located in the exhaust space 323. The air inlet, vent 324, exhaust space 323 and air outlet 13 are connected in sequence to form an air duct. After the indoor air enters through the air inlet, it will directly come into full contact with the two first heat exchangers 321 arranged at intervals along the front and back direction and exchange heat. Under the action of the fan 2, the air after heat exchange enters the exhaust space 323 through the vent 324 around the bottom of the exhaust space 323 and is discharged into the room through the air outlet 13.

[0044] The heat pump unit of this application sets up two first heat exchangers 321 spaced apart in the front-to-back direction and uses the air inlet on the left or right side of the casing 1 to achieve air intake. While maintaining the same size space, the arrangement of the first heat exchangers 321 is optimized, the overall air-facing area of ​​the first heat exchange component is increased, and the heat exchange efficiency is greatly improved.

[0045] Furthermore, by placing the fan 2 within the exhaust space 323, and providing ventilation openings 324 between the partition 12 and the first heat exchanger 321, and between the partition 12 and the sealing plate 322, the air inlet, ventilation openings 324, exhaust space 323, and air outlet 13 are sequentially connected, forming an air duct that is in full and uniform contact with the two first heat exchangers 321. This makes the heat exchange between the first heat exchanger 321 on the indoor side and the indoor air more efficient and stable, and the structure is simple. It optimizes the layout and arrangement between the first heat exchanger 321 and the fan 2, achieves a high-efficiency heat exchange effect, and also reduces installation and maintenance costs.

[0046] By optimizing the arrangement of the first heat exchanger 321 and the layout between the first heat exchanger 321 and the fan 2, a high-efficiency heat exchange effect is achieved, improving space utilization. At the same time, the modular design simplifies the structure and reduces installation and maintenance costs.

[0047] The number and location of air inlets can be set according to actual conditions. Further details can be found in [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 8 The top of the housing 1 is provided with a front side plate 141, a rear side plate 142 and a top plate 143. The front side plate 141, the rear side plate 142, the top plate 143 and the partition plate 12 form a first mounting cavity 111. The housing 1 has air inlets located on the left and right sides between the front side plate 141 and the rear side plate 142. When the mounting end allows, the two air inlets are more conducive to increasing the air inlet area and improving the heat exchange efficiency.

[0048] Alternatively, left and right side panels 144 are detachably mounted between the front side panel 141 and the rear side panel 142 of the housing 1. The left and right side panels 144 are located on the left or right side of the housing 1, and an air inlet is formed on the side of the housing 1 opposite to the side panel 144. Since the left and right side panels 144 are detachably mounted on the housing 1, it is convenient to set the air inlet on the left or right side of the housing 1 according to the customer's usage requirements, thus meeting the requirement that the installation end can freely choose the left or right side as the air inlet.

[0049] Furthermore, see Figure 4 The housing 1 has a first air guide shroud 15 at the air inlet. The first air guide shroud 15 has a first cavity and a first opening and a second opening 151 connected through the first cavity. The second opening 151 is oriented vertically and communicates with the outside so that indoor air can enter the first air guide shroud 15. The first opening is oriented horizontally and communicates with the first mounting cavity 111.

[0050] Indoor air flows sequentially through the second opening 151, the first cavity, and the first opening into the air inlet of the housing 1. By setting the first air guide shroud 15, the user can set the second opening 151 to face upwards or downwards according to the required air intake height, so as to quickly draw in indoor air and improve the air cooling effect.

[0051] Similarly, the position of the air outlet 13 and the outlet direction of the fan 2 can also be set according to actual needs to meet the installation requirements of different markets. Specifically, in some embodiments, see Figure 5 The top of the housing 1 is provided with an air outlet 13, the outlet of the fan 2 faces upward and is connected to the air outlet 13 on the top of the housing 1.

[0052] Alternatively, when the air inlet is formed on the left or right side of the housing 1, the housing 1 can be configured to have the air outlet 13 located at the top, or it can have the air outlet 13 located on the side opposite the air inlet. See [link to relevant documentation] Figure 6 The outlet of fan 2 faces the left or right side of housing 1, that is, the side opposite to the air inlet. The sealing plate 322 and the left and right side plates 144 on the same side as the air outlet 13 are all provided with openings. The outlet of fan 2 passes through the opening of sealing plate 322 and connects with the openings of left and right side plates 144 to exhaust the heat-exchanged air into the room. The air inlet of housing 1 is located on the side opposite to the outlet of fan 2, ensuring that indoor air and heat-exchanged air can enter and exit the first mounting cavity 111 separately, avoiding heat exchange between the two and thus affecting the air-cooling effect.

[0053] In some embodiments, the fan 2 includes a turbine fan, with an outlet duct 21 formed at the outlet end of the turbine fan, and an outlet formed at the end of the outlet duct 21. The vortex fan 2 can better adjust the outlet direction according to the air supply requirements at the installation end, which facilitates installation and use and reduces maintenance costs.

[0054] Further, see Figure 7 The housing 1 is provided with a second air guide shroud 5 at the air outlet 13 to discharge the air that has undergone heat exchange in the second mounting cavity 112 into the room through the second air guide shroud 5. Specifically, the second air guide shroud 5 is provided with a second cavity and a third opening and a fourth opening 51 connected through the second cavity. The third opening is connected to the air outlet 13 or the openings of the left and right side plates 144, and the orientation of the fourth opening 51 is perpendicular to the orientation of the third opening.

[0055] When the third opening is connected to the air outlet 13, the fourth opening 51 can face the left, right, front or rear side of the housing 1; when the third opening is connected to the air outlet 13, the fourth opening 51 can face the left, right, front or rear side of the housing 1, so as to meet different installation requirements of the client and make the heat pump unit more adaptable.

[0056] Furthermore, see Figure 3 The housing 1 is equipped with an electric heating element assembly 6 at the air outlet 13 to achieve auxiliary heating. When the indoor air needs heating, the air discharged by the fan 2 can supplement the heat with the auxiliary heating of the electric heating element assembly 6 to improve the overall heating effect of the unit.

[0057] In some embodiments, the housing 1 is provided with a protective net or multiple spaced protective strips at the air outlet 13 to prevent foreign objects such as mosquitoes and rodents from falling into the fan 2 and the first mounting cavity 111, thereby improving the overall service life of the device.

[0058] See Figure 3 and Figure 8In some embodiments, two first heat exchangers 321 are symmetrically arranged in the first mounting cavity 111 with the long axis of the housing 1 as the axis of symmetry. Since the two first heat exchangers 321 are symmetrically arranged, regardless of whether the air inlet is located on the left or right side of the housing 1, the air flowing into the first mounting cavity 111 is symmetrically and uniformly exchanged with the first heat exchanger 321 on the corresponding side, so as to achieve stable, uniform and sufficient heat exchange.

[0059] Further, see Figure 2 The bottom of the first heat exchanger 321 is provided with multiple support seats 8 at intervals to support the first heat exchanger 321 and ensure the stability of the first installer installation. A vent 324 is formed between two adjacent support seats 8.

[0060] See Figure 2 In some embodiments, the first heat exchanger 321 includes a finned tube heat exchanger or a microchannel heat exchanger. The windward side of the first heat exchanger 321 is located on the front and rear sides of the first mounting cavity 111, thereby maximizing the windward area and making the heat exchange process more thorough and uniform.

[0061] See Figure 2 and Figure 3 In some embodiments, the second heat exchange component includes a housing 9 and a second heat exchanger. The second heat exchanger is disposed inside the housing 9. The housing 9 is connected to a heat source inlet pipe 91 and a heat source outlet pipe 92 that communicate with the inner cavity of the housing 9. The pipe openings 93 of the heat source inlet pipe 91 and the heat source outlet pipe 92 are installed on the housing 1 and communicate with the outside, so as to facilitate the connection to an external water heat source or soil heat source, realize a modular design, and make installation and maintenance more convenient.

[0062] Furthermore, referring to the figure, housing 1 includes a detachably connected first housing and second housing. The inner cavity of the first housing forms a first mounting cavity 111, and the inner cavity of the second housing forms a second mounting cavity 112. The bottom plate of the first housing and the top plate of the second housing are combined to form a partition 12. It can be understood that the partition 12 can be formed by connecting the bottom plate and the top plate. By setting housing 1 as a detachable first housing and second housing, modular design is more conducive to its modularity. This allows for easy assembly into a whole for installation according to the requirements of the installation end, or disassembly into two parts for separate installation at different angles and positions, meeting the installation needs of different installation ends and facilitating after-sales maintenance.
