Description

Technical Field

[0001] The present application relates to the technical field of heat pump equipment, and in particular to an air source heat pump unit. Background Art

[0002] A heat pump is an efficient and energy-saving device that makes full use of low-grade thermal energy. Heat can be transferred spontaneously from a high-temperature object to a low-temperature object, but not spontaneously in the opposite direction. The working principle of a heat pump is a mechanical device that forces heat to flow from a low-temperature object to a high-temperature object in a reverse cycle. It consumes only a small amount of reverse cycle net work to obtain a large amount of heat supply, and can effectively utilize the difficult-to-apply low-grade thermal energy to achieve energy-saving purposes. As the appearance of the heat pump is the beauty of the heat pump, it is almost difficult for the side-outlet air box on the market to keep the front of the top cover in a relatively neat shape. The reason for this is that the top cover is installed in a covered manner, that is, the front end of the top cover covers the front panel, so multiple colors appear. However, if the installation method is not covered, there will be a gap between the top cover and the front panel, and water can easily enter the interior through the gap to damage electrical parts such as the electrical box.

[0030] like Figure 1-Figure 5 As shown, this embodiment provides an air source heat pump unit, including: a main body 1, an electrical box, a water receiving part 2, a guide part 3 and a waterproof part 4, the interior of the main body 1 is divided into a heat exchange area and an electrical area, the main body 1 includes a top cover plate 101, and a front panel 102 installed on the front end surface of the top cover plate 101; the electrical box is installed in the electrical area; the water receiving part 2 is arranged below the abutment position of the top cover plate 101 and the front panel 102, and is located in the electrical area; the guide part 3 abuts against the two ends of the water receiving part 2, for guiding water to flow downward; the waterproof part 4 is arranged parallel to the front panel 102, and covers the electrical box.

[0031] Based on the above scheme, the heat exchange area divided inside the main body 1 is used to install heat exchange components, and the electrical area is used to install electrical parts such as electrical boxes; since the front panel 102 is connected to the front end surface of the top cover plate 101, it is equivalent to that the front shape of the heat pump unit is the front panel 102, and the top cover plate 101 is not exposed to the front shape, so that the front shape of the heat pump unit maintains a unified and neat state, and improves the appearance of the heat pump unit; and based on the connection method of the front panel 102 and the top cover plate 101, in order to ensure the waterproof performance of electrical parts such as electrical boxes inside the heat pump unit, multiple waterproof structures are set, the first layer is to receive the water flowing down the gap between the top cover plate 101 and the front panel 102 through the water receiving member 2, the second layer is to be set at both ends of the water receiving member 2 through the guide member 3, which is used to guide the water flow downward to prevent the water from flowing to the electrical box, and the third layer is set on the front side of the electrical box through the waterproof member 4 to prevent water from splashing on the electrical box. The reliability of the air source heat pump unit in bad weather such as rain and snow is ensured through multiple waterproof structures.

[0032] It is worth mentioning that separating the heat exchanger and electrical area of ​​the heat pump can make it easier to maintain and overhaul the equipment. In the heat exchanger area, the main operations are cleaning, repairing and replacing the equipment; in the electrical area, the electrical circuit can be overhauled, replaced and debugged. This partition design can avoid mutual interference between maintenance operations of different types of equipment and improve maintenance efficiency; it also improves the safety of the heat pump. The heat exchanger and electrical area in the heat pump are designed separately to reduce the risk of fire caused by electrical failure. In the electrical area, if an electrical failure occurs, it can be repaired without affecting the heat exchanger area to avoid the spread of fire. In addition, this partition design can also reduce the risk of equipment damage and increase the service life of the equipment; at the same time, it can also improve energy utilization efficiency. The heat exchanger and electrical area of ​​the heat pump are designed separately, which can be controlled and managed more finely according to the characteristics of different areas. For example, the operating parameters of the heat exchanger can be adjusted separately according to the actual operation of the heat exchanger to improve the utilization efficiency of heat. This partition design can better meet actual needs and improve energy utilization efficiency.

[0033] In some embodiments, the main body 1 includes a middle partition, which is arranged inside the main body 1 to divide the main body 1 into a heat exchange area and an electrical area. The middle partition can effectively separate the evaporator and condenser of the heat pump to prevent the mixing of cold and hot air flows, thereby improving the energy efficiency ratio and performance coefficient of the heat pump; the middle partition can increase the heat exchange area, so that the heat exchange between the evaporator and the condenser is more sufficient, thereby improving the heat exchange efficiency of the heat pump. The middle partition can play a certain role in sound insulation and vibration reduction, reduce the noise and vibration during the operation of the heat pump, and improve the comfort and reliability of the heat pump; in addition, the design of the middle partition can make the evaporator and condenser of the heat pump independently installed and maintained, facilitate the maintenance and maintenance of the equipment, and improve the reliability and service life of the equipment; at the same time, the middle partition can effectively separate electrical components and high-temperature components, reduce safety hazards during the operation of the equipment, and improve the safety of the equipment. In summary, the provision of a middle partition can improve the heat exchange efficiency, energy efficiency ratio and performance coefficient of the heat pump, reduce noise and vibration, facilitate the maintenance and maintenance of the equipment, and improve the safety and reliability of the equipment.

[0034] Based on the scheme of providing a middle partition, the main body 1 also includes a right panel 103 installed on the side of the top cover plate 101 away from the heat exchange area, the middle partition is provided with a first folded edge toward the electrical area, and the right panel 103 is provided with a second folded edge toward the heat exchange area, and the first folded edge and the second folded edge define the guide member 3. By providing a first folded edge on the middle partition, a second folded edge on the right panel 103, and the first folded edge and the second folded edge are respectively provided at both ends of the water receiving member 2, when water flows down from both ends of the water receiving member 2, it can only flow down under the obstruction of the first folded edge and the second folded edge, preventing the water from flowing into the electrical box. In addition, the first folded edge and the second folded edge are the guide member 3, which is designed in a folded edge manner, has a simpler structure, is more convenient in processing, and is more precise in assembly.

[0035] Furthermore, the first folded edge and the second folded edge are arranged opposite to each other. The oppositely arranged first folded edge and the second folded edge can better control the water flow direction, make the water flow more uniform and smooth, and improve the water flow guiding effect. Moreover, the first folded edge and the second folded edge are opposite to each other, and the overall structure is symmetrical, which is more convenient and accurate in assembly.

[0036] Preferably, the water receiving member 2 is U-shaped, and both ends of the water receiving member 2 extend downward to form connecting parts that are detachably connected to the middle partition plate and the right panel 103. The U-shaped water receiving member 2 can better catch the water dripping from the gap between the front panel 102 and the top cover plate 101, and there will be a certain storage space for the water after it falls on the water receiving member 2. The provided connecting part is relatively independent from the main body of the water receiving member 2, and the function of the connecting part is to accurately locate the installation position of the water receiving member 2.

[0037] Furthermore, the waterproof part 4 is detachably mounted on the front side of the electrical box. Since the waterproof part 4 is detachable, when the waterproof part 4 is damaged or needs to be cleaned, it can be easily removed and repaired or replaced without removing the entire electrical box, which simplifies the repair and maintenance process; different waterproof parts 4 can be selected for installation according to actual needs and scenarios to adapt to different usage environments and needs, thereby improving the adaptability and flexibility of the equipment; the main thing is that the waterproof part 4 can effectively prevent water and dust from entering the interior of the electrical box, protect the internal electrical components and circuits from damage and corrosion, thereby improving the safety and reliability of the equipment, and at the same time, the use of the waterproof part 4 can reduce the impact of the external environment on the equipment, slow down the aging process of the equipment, and thus extend the life of the equipment.

[0038] Furthermore, the waterproof component 4 is a waterproof sheet metal, which is installed by fasteners such as screws to ensure stable installation.

[0039] Furthermore, the main body 1 also includes a bottom plate 104, the bottom plate 104 corresponds to the first drainage layer 105 of the electrical area, corresponds to the second drainage layer 106 of the heat exchange area, the vertical height of the second drainage layer 106 is lower than that of the first drainage layer 105, and a third drainage layer 107 is also provided on the bottom plate 104, the vertical height of which is lower than that of the second drainage layer 106, and the third drainage layer 107 is provided with a first drainage hole 108. The compressor installed above the first drainage layer 105 and the fin heat exchanger installed above the second drainage layer 106 are designed into multiple drainage layers in a stepped shape. During drainage, the water in the first drainage layer 105 first flows to the second drainage layer 106 and the third drainage layer 107, and the water in the second drainage layer 106 also flows to the third drainage layer 107 simultaneously, which is equivalent to the water on the bottom plate 104 finally flowing to the third drainage layer 107 after being guided by multiple drainage layers, and finally discharged from the first drainage hole 108 of the third drainage layer 107. This solution is suitable for the southern region, because the refrigeration mode is used more frequently in the southern region, and centralized drainage is more in line with the usage requirements of the southern region.

[0040] Furthermore, a fin heat exchanger is included, and the fin heat exchanger is installed in the heat exchange area. The bottom plate 104 is provided with a second drain hole 109 at a position corresponding to the fin heat exchanger. The second drain hole 109 is provided to prevent the heat pump unit from freezing when used in northern regions. The condensed water generated by the fin heat exchanger can be discharged through the second drain hole 109 in time to prevent the condensed water from freezing on the bottom plate 104 and affecting the use.

[0041] In summary, through the specialized structural design of the bottom plate 104, the heat pump unit can not only meet the needs of centralized drainage in the south, but also effectively prevent the bottom plate 104 in the north from freezing.

[0042] Preferably, a plurality of the second drainage holes 109 are provided, and the plurality of the second drainage holes 109 are evenly spaced. Since the fin heat exchanger has a large area, the plurality of second drainage holes 109 can effectively drain water, reduce the flow process of condensed water on the bottom plate 104, and can be directly discharged through the second drainage holes 109, effectively preventing ice.
