Oil separator and air conditioner having the same

Abstract

An oil separator and an air conditioner with the oil separator. The oil separator includes: an oil separation device having an oil separation space in which oil is separated from oil-containing refrigerant; a discharge pipe whose one end is connected to the compressor and the other end is connected to the oil separation device to remove the oil from the compressor. The oil-containing refrigerant discharged from the machine is guided to the oil separation device; and the oil drop forming unit is provided in the discharge pipe so that at least a part of the oil particles contained in the refrigerant passing through the discharge pipe enters the oil separation device in the state of oil droplets. Therefore, the oil separation performance of the oil separation device can be improved because the burden of separating oil by the oil separation device is reduced; and the time for the oil separation device to separate oil can be shortened; the size of the oil separation device can be reduced; The overall performance of the air conditioner of the separator can be improved.

Description

technical field [0001] The present invention relates to an air conditioner, in particular to a miniaturized oil separator with improved oil separation function, and an air conditioner with the oil separator. Background technique [0002] Generally, an oil separator is a device for separating oil contained in refrigerant discharged from a compressor to a condenser and then returning the separated oil to the compressor. [0003] will now refer to Figure 1 to Figure 3 Explain an air conditioner with an oil separator. figure 1 is a schematic diagram showing an air conditioner with a prior art oil separator, figure 2 yes figure 1 Longitudinal sectional view of the oil separator, image 3 yes figure 1 Transverse sectional view of the oil separator. Here, arrows indicate the flow of oil-containing refrigerant flowing into the oil separator 25 . [0004] Such as figure 1 As shown, the air conditioner is provided with an indoor unit 10 and an outdoor unit 20 , and the in...

AI Technical Summary

Problems solved by technology

[0015] The increase in the contact area and radius increases the height of the housing 26, which makes it difficult to manufacture small-sized oil separators 25

[0016] On the other hand, when the shell 26 with a larger height and radius is used, it takes longer to separate the oil from the refrigerant, which causes a delay in the oil supply time from the oil separator 25 to the compressor 21, thereby causing Lack of oil in the compressor 21, which may damage the compressor 21
