Embodiment Construction

[0029] Such as Figure 2-7 As shown, the present invention provides an air-conditioning system, which includes a compressor 1 having a discharge chamber and a suction chamber, and a liquid storage tank 2 communicating with the suction chamber of the compressor 1. The air flow upstream end of the discharge chamber of the compressor 1 is also provided with a discharge valve plate, and the air conditioning system also includes the refrigerant required for filling the air conditioning system into the discharge chamber of the compressor 1 and / or the large valve structure of the suction cavity3. There are two valves, one large and one small, on the outdoor unit of the air conditioner. The large valve and the small valve are relative terms of pipe diameter. (Usually, at present, the outer diameter of the copper pipe of the small valve of the company's household air conditioner is D6 (mm), and the large valve has specifications such as D9.52, D12, D18, and D24 (mm). This specificat...

Abstract

The invention provides a refrigerant pouring method of an air conditioner outdoor unit. The air conditioner outdoor unit comprises a compressor (1) and an outdoor unit heat exchanger (5); and the compressor (1) comprises an air suction cavity and an exhausting cavity. The outdoor unit further comprises an air suction cavity and / or an exhausting cavity communicating with the compressor (1) through a communicating pipeline and / or a large valve (3) and a small valve (6) of the outdoor unit heat exchanger (5); and the large valve (3) is used for pouring refrigerants into the exhausting cavity and / or the air suction cavity of the compressor (1). By means of an air conditioner system, the pouring speed of the refrigerants ( especially R32) of the air conditioner system can be effectively increased, and therefore the running and producing efficiency of the air conditioner system is improved; and the pouring precision of the refrigerants (especially R32) of the air conditioner system can also be effectively improved, the pouring precision is more accurate, and the running and producing efficiency of the air conditioner system is further improved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and air conditioning, and in particular relates to a refrigerant filling method for an outdoor unit of an air conditioner. Background technique [0002] In the prior art, in the air-conditioning industry, two refrigerant injection methods are usually used for the refrigerant injection of the outdoor unit of the split air conditioner: process pipe injection and small valve injection. The refrigerant in both methods directly enters the exhaust side of the outdoor unit (the main Cylinder and outdoor unit heat exchanger), it will not affect the operation of air conditioning products. [0003] However, in recent years, compared with traditional refrigerants, R32 refrigerant has the advantages of energy saving, greenness, no damage to the ozone layer, no explosion, non-toxicity, and safety. At present, the industry is vigorously promoting the development of R32 refrigerant air conditioners. Howev...
