Description

Technical Field

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

[0002] The anti-Carnot principle of the air source heat pump is a device that uses the energy in the air as its main driving force. Through the compression of the compressor, it absorbs a large amount of low-temperature thermal energy in the air and converts it into high-temperature thermal energy.

[0003] Air-source heat pumps are prone to freezing in low-temperature environments, causing damage or malfunction. Existing antifreeze measures are mostly designed for pipes, using insulation to coat them. However, heat exchangers require direct contact with air to improve refrigerant conversion efficiency, so this approach is generally not used. To prevent freezing, heat exchangers are often left connected to the power supply, which wastes more energy. Once frozen, hot water irrigation is required to melt the ice, which is a complex operation. Utility Model Content

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the utility model is that the heat insulation material is wrapped to isolate the air from direct contact, which reduces the heat exchange efficiency, wastes energy by keeping the power supply connected, and the ice-melting operation is troublesome.

[0006] 2. Technical Solution

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: an antifreeze air energy heat pump, including a refrigerant pipe located on a heat exchanger, the refrigerant pipe is rotatably connected with a dynamic ring near both ends, the dynamic ring is circumferentially connected with a plurality of fan blades, a first annular cavity is connected inside the dynamic ring, a brush plate is connected relative to the dynamic ring, the brush plate is connected with a plurality of bristles on the side close to the refrigerant pipe, the bristles abut the refrigerant pipe, and the brush plate is connected with a ventilation component that can spray air to the outer wall of the refrigerant pipe.

[0008] Furthermore, the air supply assembly includes a fixed ring connected to the side of the refrigerant pipe away from the dynamic ring, a second ring cavity is connected inside the fixed ring, an air intake pipe is connected to the side of the fixed ring away from the dynamic ring, and an air guide ring plate is connected to the other side of the fixed ring. The air guide ring plate is rotatably sealed and connected to adjacent dynamic rings, and a plurality of air guide holes are connected on the air guide ring plate. The air intake pipe is connected to the first ring cavity through the second ring cavity and the air guide holes in sequence.

[0009] Furthermore, the fan blades on the two sides of the dynamic ring are tilted and arranged on the dynamic ring.

[0010] Furthermore, the air intake pipe, fixed ring, dynamic ring, air guide ring plate and brush plate are all made of thermal insulation materials.

[0011] Furthermore, the ventilation assembly includes connecting columns connected to both ends of the brush plate, the connecting columns extend into the first annular cavity, a main channel is provided through the connecting columns and the brush plate, the main channel is connected to the adjacent first annular cavity, and a plurality of spray holes are evenly distributed and connected on the side of the brush plate close to the refrigerant pipe.

[0012] Furthermore, the spray holes and the bristles are spaced apart.

[0013] 3. Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are:

[0015] The rotation coordination of the fan blades, the dynamic ring and the refrigerant pipe makes it convenient for the external air to pass through the refrigerant pipe at an accelerated speed under the drive of the intake fan, so that the refrigerant pipe containing refrigerant can absorb the heat in the air by exchanging heat with more air. At the same time, as the air is introduced, the driving fan blades automatically drive the dynamic ring and the brush plate to rotate. The bristles on the brush plate can clean the surface of the refrigerant pipe to avoid ice formation and affect the heat exchange between the refrigerant pipe and the air. When the temperature is too low, the air supply component can also be used to guide part of the hot air flow into the ventilation component on the brush plate when the refrigerant pipe has frozen, so as to facilitate the preheating and de-icing operation of the refrigerant pipe surface.

[0024] Through the above structure, the fan blades 3 can drive the dynamic ring 2 to drive the brush plate 6 to rotate, and the brush plate 6 can clean the surface of the refrigerant pipe 1 through the bristles 7 to prevent ice from forming.

[0025] Example 2

[0026] On the basis of embodiment 1, combined with the attached Figure 3 and Figure 4 , the brush plate 6 is connected with a ventilation component that can spray air to the outer wall of the refrigerant pipe 1, the ventilation component includes connecting columns 12 connected to both ends of the brush plate 6, the connecting column 12 extends into the first annular cavity 4, the connecting column 12 and the brush plate 6 are penetrated and connected with a main channel 13, the main channel 13 connects the adjacent first annular cavity 4, the brush plate 6 is evenly connected with a plurality of spray holes 5 on the side close to the refrigerant pipe 1, the spray holes 5 are spaced apart from the bristles 7; one side of the dynamic ring 2 is connected with an air supply component, the air supply component includes a fixed ring 8 connected to the side of the refrigerant pipe 1 away from the dynamic ring 2, a second annular cavity is connected in the fixed ring 8, the fixed ring 8 is connected with an air inlet pipe 9 on the side away from the dynamic ring 2, and the other side of the fixed ring 8 is connected with an air guide ring plate 10, the air guide ring plate 10 is rotatably sealed and connected to the adjacent dynamic ring 2, and a plurality of air guide holes 11 are connected on the air guide ring plate 10, and the air inlet pipe 9 is communicated with the first annular cavity 4 through the second annular cavity and the air guide holes 11 in turn.

[0027] The arrangement of the air supply assembly in the above structure facilitates the defrosting of the refrigerant pipe 1 when it is frozen. When the temperature is very low, the hot air generated or the hot air output from the evaporator end can be diverted into the air inlet pipe 9, and then introduced into the ventilation assembly through the ventilation assembly, so as to facilitate preheating the surface of the refrigerant pipe 1.
