In the running process of the air-cooled heat pump unit, when the refrigerant filling amount is too large, the specification of the expansion valve is too large or the superheat degree setting value is too low, and particularly when the four-way valve is switched in a defrosting mode or is switched out of the defrosting mode, liquid refrigerant inevitably enters the compressor.
When liquid refrigerant enters the compressor, lubricating oil on the bearing and the rotor is diluted, so that an oil film is damaged and the lubrication fails, the abrasion of the bearing and the rotor is accelerated, and the serious fault of the compressor is caused; meanwhile, due to the reduction of the exhaust temperature, the oil throwing risk exists after the oil content efficiency of the compressor is reduced, and a large amount of lubricating oil is taken away from the compressor. To avoid this, a gas-liquid separator is typically added between the evaporator and the compressor suction to separate the liquid refrigerant that is about to enter the compressor.
The traditional gas-liquid separator has a simple structure, is generally in a gravity settling type, utilizes the difference of the densities of gas and liquid, when the gas and the liquid flow together, the liquid is acted by gravity to generate a downward speed, and the gas still moves towards the original direction, so that the gas-liquid separation is realized. When the air-cooled heat pump enters a defrosting mode or exits the defrosting mode, the four-way valve is switched, a large amount of liquid refrigerant in the air-conditioning water side heat exchanger or the fin heat exchanger is intensively introduced into the gas-liquid separator in a very short time, and the liquid level of the gas-liquid separator is raised. Since the suction pressure of the system is reduced rapidly, the liquid refrigerant foams in the gas-liquid separator, so that a large amount of foamed refrigerant liquid flows into the gas outlet pipe and finally enters the compressor, the wet operation of the compressor is caused, the lubrication of the compressor is damaged, the oil of the compressor is thrown, the oil shortage of the compressor is caused, and the reliability of the compressor is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome prior art not enough, provide a take vapour and liquid separator of horizontal baffle.
