Air Conditioning System

Abstract

The invention provides an air-conditioning system, comprising: a compressor (10) having an air inlet and an air outlet; end and exhaust end, the exhaust end of each suction branch pipe (20) is connected with the air inlet of the compressor (10); the suction main pipe (22) is located between the compressor (10) and each suction branch pipe (20) ), the main suction pipe (22) communicates with the compressor (10) and each suction branch pipe (20) respectively. The air conditioning system of the invention improves the service life of the compressor.

Description

Technical field [0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning system. Background technique [0002] At present, the working process of the air conditioning system is mainly as follows: figure 1 As shown, the compressor 1'compresses the low-temperature and low-pressure gaseous refrigerant entering it into a high-temperature and high-pressure gaseous refrigerant, and then the refrigerant flows into the condenser to form a liquid refrigerant under the action of the condenser. The agent flows into the evaporator and forms a low-temperature and low-pressure gaseous refrigerant under the action of the evaporator, and then flows into the compressor 1'through the intake pipe 2'for compression. In order to prevent liquid refrigerant from flowing into the compressor 1', a liquid separator is provided between the compressor 1'and the evaporator. For central air conditioners that require a lot of refrigerant, in ord...

Problems solved by technology

[0003] However, in order to make the air-conditioning system work normally, the refrigerant contains lubricating oil. Since the displacement of the air-conditioning system at full load and partial load is quite different, the flow rate of the gaseous refrigerant entering the compressor 1' is also quite different. Therefore, , when the air-conditioning system is working at low load, the gaseous refrigerant cannot carry sufficient lubrication into the compressor 1′ because the flow rate of the gaseous refrigerant is too small, which reduces the service life of the compressor 1′

In some air-conditioning systems, the intake pipe 2' connected to the air inlet of the compressor 1' is relatively long, and the resistance of gas flow in the air intake pipe 2' is relatively large, and the air intake pipe 2' is at the air inlet of the compressor 1' The resulting pressure drop is relatively large, which further causes the gaseous refrigerant to fail to carry enough lubricating oil into the compressor 1', further reducing the service life of the compressor 1'

In addition, based on the large difference between the full load and partial load of the air conditioning system, the flow rate of the liquid refrigerant flowing from the liquid storage tank 3' to the condenser through the liquid inlet pipe 4' is unstable, which in turn leads to unsmooth liquid supply and affects Normal operation of the air conditioning system
