Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, and more specifically, to an air source heat pump for trigeneration. Background Art

[0002] Air source heat pump trigeneration is a device driven by a motor, steam compression cycle and air as a heat source. It can provide cooling and domestic hot water, heating and domestic hot water at the same time, and provide cooling, heating and domestic hot water separately. This device integrates heat pump air-conditioning technology, heat pump water heater technology and advanced heat exchange technology to achieve a perfect combination of air conditioning and water heaters, and is suitable for indoor swimming pools, factories, farms and other places that require hot water heat sources.

[0003] At present, the air source heat pumps on the market can convert low-level thermal energy that cannot be directly used into high-level thermal energy that can be used, thereby achieving the purpose of saving some high-level energy. When the air source heat pump is operating in a low-temperature environment, electric energy is required to control the operation of the air source heat pump, and it will drive air into the air source heat pump. Because the air will carry water molecules, it will lead to increased loss of electric power resources and affect the working efficiency of the air source heat pump. In order to solve this phenomenon, a water vapor separation plate is added at the air inlet to filter water vapor and foreign matter in the air.

[0004] However, in actual use, after the water vapor separation plate filters the water vapor, the water vapor adheres to the surface of the separation plate, causing the surface of the separation plate to be moist. When foreign matter in the air comes into contact with the separation plate, the foreign matter becomes moist and sticks to the separation plate. After a long period of air filtration, the foreign matter is easily accumulated on the separation plate and causes the separation plate to be blocked, thus affecting the efficiency of air filtration.

DETAILED DESCRIPTION

[0021] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Furthermore, the number of the two sleeve rods 502 is set to multiple groups and are evenly installed on the outside of the rotating drum 504. One end of the support rod 505 is slidably set inside the sleeve rod 502, and a spring 507 is provided between the support rod 505 and the sleeve rod 502.

[0024] Furthermore, two arc plates 508 are provided on one side of the dehumidification plate 4 close to the vertical rod 501 , and the two arc plates 508 are symmetrically installed inside the air inlet duct 2 . A limit frame 509 is provided on the other side of the dehumidification plate 4 , and the limit frame 509 is connected to the air inlet duct 2 .

[0025] It should be noted that the space formed between the arc plate 508 and the limiting frame 509 can limit the dehumidification plate 4; the dehumidification plate 4 filters the air through the activated carbon particles inside the plate body to achieve dehumidification.

[0026] For further information, please refer to the attached manual. Figure 1 A water collecting frame 6 is provided at the bottom of the air inlet duct 2, and a leakage hole is provided on the surface of the air inlet duct 2. The leakage hole is located on one side of the dehumidification plate 4, and the water collecting frame 6 is communicated with the leakage hole.

[0027] It should be noted that the liquid dropped from the dehumidification plate 4 can enter the water collecting frame 6 through the leakage hole, and the liquid can be collected to prevent the liquid from being deposited in the air inlet duct 2.

[0028] For further information, please refer to the attached manual. Figure 1 , 4 A groove 7 is provided on the surface of the air inlet duct 2, a through hole is provided at the bottom of the groove 7, the top of the dehumidification plate 4 is located inside the through hole, a sealing ring 8 is provided on the surface of the groove 7, the sealing ring 8 is located outside the through hole, a cover plate 9 is provided inside the groove 7, one side of the cover plate 9 is hinged to the air inlet duct 2, and a limit plate 10 is rotatably provided on the top of the air inlet duct 2, and the limit plate 10 is located on the top of the cover plate 9.

[0029] It should be noted that the sealing ring 8 can reduce the gap between the cover plate 9 and the groove 7 and prevent liquid from entering through the groove 7.

[0030] For further information, please refer to the attached manual. Figure 1 The heat pump body 1 includes a shell 11, and an evaporator, a compressor, a condenser and an expansion valve are arranged inside the shell 11.

[0031] It should be noted that the heat pump body 1 utilizes the working principle of the refrigerant compression refrigeration heat release cycle, uses the heat source in the ambient air as the low-temperature heat source, exchanges heat through the condenser or evaporator in the traditional air conditioner, and then releases heat energy through the circulating heat exchange system. Finally, the water pump circulating heat exchange system is used to transfer energy to the building to meet users' needs for domestic hot water, floor heating or air conditioning.

[0032] Working principle: First, start the heat pump body 1, and suck the outside air into the heat pump body 1 through the air inlet duct 2. The moisture in the air can be removed through the dehumidification plate 4, and then the water flows into the water collecting frame 6 through the leakage holes on the surface of the air inlet duct 2.

[0033] Next, when the air flows, a thrust is formed on the wind plate 503 outside the rotating drum 504, which can drive the rotating drum 504 to rotate on the vertical rod 501, and the rotating drum 504 drives the sleeve rod 502 and the support rod 505 to rotate, so that the brush plate 506 at one end of the support rod 505 moves along the dehumidification plate 4, which can not only brush off the adhered liquid on the dehumidification plate 4, but also clean it to prevent foreign matter in the air from adhering to the dehumidification plate 4;

[0034] When the brush plate 506 moves, the spring 507 between the sleeve rod 502 and the support rod 505 causes the rotating drum 504 to move the support rod 505, causing it to slide inside the sleeve rod 502 and drive the spring 507 to stretch. When the brush plate 506 contacts the dehumidification plate 4, a reverse thrust is formed, which can retract the support rod 505 into the sleeve rod 502. When the brush plate 506 contacts the filter plate 3, a thrust is directly formed on the brush plate 506, causing the support rod 505 to slide out of the sleeve rod 502, thereby allowing the dehumidification plate 4 and the filter plate 3 to be cleaned simultaneously.

[0035] Then, when the dehumidification plate 4 needs to be disassembled, the limiting plate 10 on the top of the air inlet duct 2 is rotated to remove the limiting plate 10 from the cover plate 9, and then the cover plate 9 is pulled to open the groove 7, and the dehumidification plate 4 can be pulled out from the inside of the through hole, so that the dehumidification plate 4 can be disassembled and replaced conveniently.

[0036] The utility model drives the rotating drum 504 through the wind plate 503, so that the brush plate 506 contacts the surface of the dehumidification plate 4 or the filter plate 3, so as to clean it; by opening the cover plate 9 and exposing the groove 7, the dehumidification plate 4 can be disassembled and replaced.

[0037] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
