Technical Field

[0001] The utility model belongs to the technical field of heat pumps, and particularly relates to a defrosting structure of an air source heat pump. Background Art

[0002] An air source heat pump is a device that utilizes low-grade heat energy in the air, increases its temperature and pressure through the work of a compressor, and thus provides heating, cooling, and domestic hot water for buildings. Its working principle is similar to the reverse process of a refrigerator or an air conditioner, and its core components include a compressor, an evaporator, a condenser, and an expansion valve.

[0003] When a traditional air source heat pump operates in a low-temperature and high-humidity environment, its outdoor heat exchanger surface is prone to frosting. Frosting will hinder air flow, reduce heat exchange efficiency, cause the system to frequently start the defrosting program, thus significantly increasing energy consumption. In addition, long-term frosting may also affect the stability and service life of the equipment.

[0004] Therefore, there is a particular need for a defrosting structure of an air source heat pump to solve the above problems. Content of the Utility Model

The heater is installed on one side of the air source heat pump body. The circulation pipe is installed on the heater and surrounds a part of the area of the air source heat pump body. It also includes a connecting shell, a top shell, and an air outlet pipe. The connecting shell is installed on the air source heat pump body. The two connecting pipes simultaneously pass through the connecting shell and extend to the outside. The upper part of the circulation pipe passes through the connecting shell and is located inside it. The top shell is installed on the upper part of the connecting shell and completely covers the area above the two fan modules. On both sides of the lower part of the top shell, multiple horizontally arranged air outlet pipes are fixedly connected. The multiple air outlet pipes on one side are connected to the inside of the connecting shell, and the multiple air outlet pipes on the other side are located in the upper rear area of the air source heat pump body.

[0007] As a preferred technical solution of the utility model, it also includes a connecting plate and streamers. The connecting plate is installed on one side of the upper part of the connecting shell, and multiple streamers are tied to both sides of it.

[0008] As a preferred technical solution of the utility model, it also includes a filter plate. The filter plate is installed at the front of the connecting shell.

[0009] As a preferred technical solution of the present utility model, it further includes an adsorption plate, and the adsorption plate is installed at the front of the connection shell and is located directly behind the filter plate.

[0010] As a preferred technical solution of the present utility model, it further includes a filter screen, and a filter screen is fixedly connected to the inner lower end of each air outlet pipe.

[0011] As a preferred technical solution of the present utility model, the streamer is made of waterproof material.

[0012] Beneficial effects: 1. By setting the connection shell, the top shell and the air outlet pipe, a reasonable gas flow path is formed, so that good air flow can be maintained on both the front and rear sides of the air source heat pump body, effectively reducing the possibility of frosting, significantly delaying the frosting time, thereby reducing problems such as performance degradation and increased energy consumption caused by frosting, and improving the overall operation efficiency and reliability of the equipment.

[0020] Embodiment: An air source heat pump defrosting structure, as Figures 1 - 5As shown in the figure, it includes an air source heat pump body 1, a fan module 2, a connecting pipe 3, a filter plate 8, an adsorption plate 9, a heater 10 and a circulation pipe 11. Two fan modules 2 are arranged side by side and bolted to the top of the air source heat pump body 1. Two connecting pipes 3 are distributed vertically along the same vertical line and bolted to the lower left side of the air source heat pump body 1. The filter plate 8 and the adsorption plate 9 are both bolted to the front of the connecting shell 4. Among them, the adsorption plate 9 is located directly behind the filter plate 8. The heater 10 is bolted to the rear of the air source heat pump body 1. The circulation pipe 11 is bolted to the heater 10 and surrounds a part of the area of the air source heat pump body 1. It also includes a connecting shell 4, a top shell 5, an air outlet pipe 6 and a filter screen 7. The connecting shell 4 is bolted to the air source heat pump body 1. Two connecting pipes 3 pass through the connecting shell 4 at the same time and extend to its outside. The upper part of the circulation pipe 11 passes through the connecting shell 4 and is located inside it. The top shell 5 is bolted to the upper part of the connecting shell 4 and completely covers the upper area of the two fan modules 2. Four horizontally arranged air outlet pipes 6 are welded on the front and rear sides of the lower part of the top shell 5. The four air outlet pipes 6 on the front side are connected to the inside of the connecting shell 4. The four air outlet pipes 6 on the rear side are located in the upper rear area of the air source heat pump body 1. A filter screen 7 is welded to the inner lower end of each air outlet pipe 6. When the front row of air outlet pipes 6 discharges gas into the inside of the connecting shell 4 and disperses it on the front side of the air source heat pump body 1, the filter screen 7 can intercept particulate impurities in the gas, preventing the particulate impurities from adhering to the rear surface of the adsorption plate 9 along with the air flow, thereby preventing the adsorption plate 9 from being blocked.

[0021] As Figure 4 and Figure 5 shown in the figure, it also includes a connecting plate 12 and streamers 13. The connecting plate 12 is bolted to the upper front side of the connecting shell 4. Five streamers 13 are tied to each of its left and right sides. The streamers 13 are made of waterproof materials, such as high-strength waterproof nylon cloth, and have excellent waterproof performance.

[0022] During the normal operation of the air source heat pump body 1, the fan module 2 starts to operate to generate a strong suction force, sucking the outside gas from the front side of the air source heat pump body 1 into its interior. Before the gas enters the air source heat pump body 1, the filter plate 8 intercepts particulate impurities in the gas, preventing these impurities from entering the interior of the air source heat pump body 1 and causing damage to the equipment. At the same time, the adsorption plate 9 adsorbs the moisture in the gas, reducing the moisture content of the gas and creating good conditions for the efficient operation of the air source heat pump body 1;

[0023] While the fan module 2 sucks in the outside air, it also discharges the air inside the air source heat pump body 1. The discharged air first enters the top shell 5 and then is discharged orderly through two exhaust pipes 6 arranged on the front and rear sides. One exhaust pipe 6 on the rear side discharges the air to the rear side of the air source heat pump body 1, making the air on the rear side of the heat pump flow. One exhaust pipe 6 on the front side discharges the air into the connection shell 4. After this part of the air is dispersed in the connection shell 4, it further forms an air flow on the front side of the air source heat pump body 1 and is discharged to the outside after passing through the adsorption plate 9 and the filter plate 8 in sequence;

[0024] When the air source heat pump body 1 is running normally, it continuously discharges air from its front side. The discharged air has a certain flow rate and force. When the discharged air blows the ribbon 13, the ribbon 13 will flutter accordingly. By observing the fluttering situation of the ribbon 13, users can intuitively judge whether the air source heat pump body 1 is in the running state;

[0025] When the air source heat pump body 1 has a frosting phenomenon, directly start the heater 10. After the heater 10 starts to work, the heat will be transferred to the periphery of the air source heat pump body 1 through the circulation pipe 11 to heat and defrost the frost layer on the surface of the air source heat pump body 1. After the defrosting is completed, turn off the heater 10 and resume the normal running state.
