Problems solved by technology
However, it is difficult for the horizontal gas-liquid separator to use gravity as a booster for gas-liquid separation, so it is necessary to work hard on the structure to ensure the same separation effect as the vertical gas-liquid separator, and to achieve a balance between space and effect

Abstract
The invention discloses a gas-liquid separator behind an evaporator for an air-cooled heat pump unit. The gas-liquid separator comprises a horizontal cylinder, a front cover, a rear cover, an air outlet pipe and visual liquid level devices; the horizontal cylinder is a horizontally-placed circular iron cylinder, and an outlet of an inlet pipe is welded with a transverse plate; the front cover is acircular plate; the rear cover is a circular plate; the air outlet pipe is the pipe with straight pipes at the two ends and with a smooth transition bending middle; and the visual liquid level devices are liquid level instruments, and observation tubes are made of transparent PVC, are sealed by nitrile rubber gaskets, and are fastened and fixed by threaded covers. According to the gas-liquid separator, the inlet pipe is arranged to enable a refrigerant entering the horizontal cylinder to be far away from the air outlet pipe as far as possible so as to increase the gas-liquid separation distance, meanwhile, the transverse plate can play the role of blocking liquid in the refrigerant, so that gas-liquid separation is accelerated.
Description
technical field [0001] The invention relates to the technical field of central air conditioning, in particular to a gas-liquid separator for an air-cooled heat pump unit behind an evaporator. Background technique [0002] The machines that provide cooling capacity for central air conditioners are generally large chillers, and a huge amount of refrigerant is required in the refrigerant pipeline. The position of the gas-liquid separator is after the evaporator in the refrigerant pipeline and before the compressor. On the one hand, it is used to prevent the liquid refrigerant in the compressor from entering the compressor, causing damage to the compressor. On the other hand, the gas-liquid separator simultaneously It plays the role of liquid storage, because large chillers use a large amount of refrigerant, and different amounts of refrigerant can be used under different working conditions. [0003] The air-cooled unit adopts an air-cooled condenser (copper tube expanded alumi...
