Description

Technical Field

[0001] The utility model belongs to the technical field of gas-liquid separation equipment, and in particular relates to a gas separation end cover component for an air conditioner. Background Art

[0002] At present, in order to ensure the safe operation of the compressor and prevent the compressor from being damaged by liquid shock caused by the liquid refrigerant sucked into the compressor air inlet, a gas-liquid separator needs to be added to the system. By using the principle of different specific gravity of gas and liquid, the vapor rises to the top and returns to the compressor. The refrigerated liquid gradually vaporizes at the bottom of the gas-liquid separator and then returns to the compressor, thereby preventing liquid refrigerant from entering the compressor.

[0003] The existing gas-liquid separator includes a cylinder and two conduits, one is an air outlet pipe (U-shaped), and the other is a liquid inlet pipe (bend at about 135°). The lower ends of the two pipes are inserted into the cylinder, and the lower end of the air outlet pipe is provided with an oil return hole and a filter. The upper ends of the two conduits are connected to the system pipeline.

[0004] In the prior art, the gas-liquid separator is generally fixedly installed in the condenser by providing a mounting plate on the end cover at the end of the cylinder. Since the end cover of the cylinder is of arc-shaped design, the contact area between the mounting plate and the end cover is small, resulting in reduced installation stability.
