Problems solved by technology

[0005] Such a design structure will occupy the internal space of the gas-liquid separator and reduce the effective volume. Therefore, the size of the gas-liquid separator must be increased to make up for this loss; The lower part of the gas-liquid separator, or the long-term heating operation of the air-conditioning product under low temperature conditions, the liquid refrigerant and the refrigerated lubricating oil will be stratified. The lubricating oil layer is above the liquid refrigerant layer, and the oil return hole close to the bottom of the outlet pipe is difficult to ensure that the refrigerated oil flows back to the compressor smoothly, and at this time, part of the liquid refrigerant will flow back to the compressor from the oil return hole

Abstract

The invention provides an air-liquid separator used for an air conditioner, which comprises a barrel body, an air inlet pipe and an air outlet pipe provided with a U-shaped pipe, wherein the U-shaped pipe is arranged on the outer side of the barrel body; an equalizing pipe is arranged between the air outlet pipe and the barrel body; and at least two oil return holes are formed in the air outlet pipe. According to the air-liquid separator used for the air conditioner, a reasonable structure design enables the external size of the air-liquid separator to be miniaturized; and meanwhile, the long-term heating operation of the air conditioner under the low-temperature operating condition is effectively guaranteed, refrigerant oil can smoothly and completely flow back to a compressor, and the reliability and the stability of the operation of the compressor are enhanced.

Description

technical field [0001] The invention relates to a gas-liquid separator, in particular to a gas-liquid separator for an air conditioner, and belongs to the technical field of air conditioner production. Background technique [0002] The gas-liquid separator for air conditioning is generally set on the low-pressure pipeline between the four-way reversing valve and the compressor and close to the inlet of the compressor. The position in the air conditioning system is as follows: figure 1 shown. The function of the gas-liquid separator in the air conditioning system is to separate and save the refrigerant liquid in the return air pipe, effectively preventing the occurrence of compressor liquid hammer. Moreover, an oil hole is set at the bottom of the air outlet pipe of the gas-liquid separator to ensure that during the process of separating and storing the refrigerant liquid, the refrigerating oil is separated at the same time, and the refrigerating oil is returned to the compr...
