Problems solved by technology

Due to the low heat exchange efficiency between the wind and the heat exchanger, it is not convenient to optimize the air conditioning system and improve the EER of the air conditioning system (that is, the cooling energy efficiency ratio = air conditioning cooling capacity / air conditioning power consumption)
If you want to increase the EER of the air-conditioning system, you must increase the heat exchange area of ​​the air-conditioning heat exchanger, which will inevitably make the heat exchanger larger, resulting in an increase in air-conditioning costs and a waste of national copper and aluminum resources.
Existing outdoor units of household air conditioners have the problem of low heat exchange efficiency due to the simple use of air cooling

Embodiment 1

[0017] refer to figure 1 , figure 2 , Embodiment 1 includes a box body, a heat exchanger 2, a motor 3, an axial fan 7, a compressor 8, a control system 9, and a water-cooled heat exchange mechanism. The water cooling heat exchange mechanism is composed of a latent heat exchanger 1 , a water pump assembly 5 , a water supply assembly 6 and a water tank 10 . The latent heat exchanger is composed of small units 11 connected one by one, and each small unit 11 is a hollow long hexahedron structure such as Figure 5 As shown, the wind passes along the hollow direction of the small unit 11 . Such as Figure 6 As shown, holes 12 can be arranged on the hollow long hexahedron of each small unit 11 of the latent heat exchanger 1, and the holes 12 opened on each hexahedron can be square holes such as Figure 7 As shown, it is also possible to open holes of other shapes, such as triangular holes and the like. The latent heat exchanger 1 is made of water-absorbing and water-permeable m...

Embodiment 2

[0019] refer to image 3 , Embodiment 2 has the same structure as Embodiment 1, except that the second heat exchanger 4 is arranged in the water tank, and the lower part of the heat exchanger 2 is placed in the water tank 10 . When part of the heat exchanger 2 is submerged in water, when the outdoor unit of the air conditioner is combined with the indoor unit of the air conditioner to perform a refrigeration cycle, the refrigerant in the refrigeration system flows as follows: compressor 8——heat exchanger 2——second heat exchanger 4—throttling device—indoor unit heat exchanger—compressor 8. The basic principle is: when the high-temperature and high-pressure refrigerant gas is discharged from the compressor, it first enters the heat exchanger 2 to exchange heat with the wind with a lower temperature and an increased humidity after heat exchange with the latent heat exchanger 1, and then in the Heat exchange with water in the heat exchanger 2, and then enter the second heat excha...

Embodiment 3

[0021] refer to Figure 4 , embodiment 3 has the same structure as embodiment 1, except that the second heat exchanger 4 is arranged in the water tank, and the heat exchanger 2 is placed in the box outside the water tank 10, and the outdoor unit of the air conditioner and the indoor unit of the air conditioner are combined for cooling During circulation, the refrigerant in the refrigeration system flows as follows: compressor 8—heat exchanger 2—second heat exchanger 4—throttling device—indoor unit heat exchanger—compressor 8. The basic principle is: when the high-temperature and high-pressure refrigerant gas is discharged from the compressor, it first enters the heat exchanger 2 to exchange heat with the wind with reduced temperature and increased humidity after heat exchange with the latent heat exchanger 1, and then enters the After the second heat exchanger 4 exchanges heat with the water in the water tank 10, a high-pressure and low-temperature refrigerant liquid is obtain...

Abstract

The present invention relates to an air conditioner outdoor unit adopting axial-flow fan system. It includes the following several portions: a box body, a water-cooling heat-exchanging mechanism mounted in the box body, said water-cooling heat-exchanging mechanism is formed from water pump, water tank, hidden heat heat-exchanger and water-supplying component. Besides, said invention also provides their connection mode. Said invention can greatly raise heat-exchanging efficiency of existent domestic air conditioner.

Description

technical field [0001] The invention relates to an outdoor unit of an air conditioner, more specifically an outdoor unit of an air conditioner adopting an axial flow fan system. Background technique [0002] The outdoor unit of the existing household air conditioner generally consists of a heat exchanger, a fan motor, an axial flow fan, a compressor, a control system, etc. installed in a casing, and adopts an air-cooled method. Due to the low heat exchange efficiency between the wind and the heat exchanger, it is not convenient to optimize the air-conditioning system and improve the EER of the air-conditioning system (that is, the cooling energy efficiency ratio = air-conditioning cooling capacity / air-conditioning power consumption). If you want to increase the EER of the air-conditioning system, you must increase the heat exchange area of ​​the air-conditioning heat exchanger, which will inevitably make the heat exchanger larger, resulting in an increase in air-conditioning...
