Flash evaporator and air conditioner

Abstract

The invention provides a flash evaporator and an air conditioner. The flash evaporator comprises a barrel and a sealing component, the lower portion of the barrel is provided with a first refrigerant access port and a second refrigerant access port, the upper portion of the barrel is provided with an air outlet, and the sealing component is mounted in the barrel relative to the air outlet and capable of moving up or down under the action of liquid refrigerant to seal or unseal the air outlet. Since the flash evaporator is provided with the sealing component, when the refrigerant is accumulated more and more in the barrel due to the fact that the liquid refrigerant does not timely flow out from the first refrigerant access port or the second refrigerant access port, the sealing component is capable of moving up under the action of liquid refrigerant to seal the air outlet, the problem that liquid shock of a compressor is caused by the fact that the liquid refrigerant enters the compressor from the air outlet of the flash evaporator is effectively avoided, reliability in operation of the compressor is effectively guaranteed, and reliability of an air conditioning system is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of household appliances, more specifically, to a flash evaporator and an air conditioner containing the flash evaporator. Background technique [0002] The flash evaporator is a gas-liquid separator used in compression or quasi-two-stage compression air-conditioning systems to achieve gas-liquid separation, the gas returns to the compressor, and the liquid continues to evaporate, which can effectively increase the low-temperature heating capacity. [0003] The flash evaporator used in the prior art is usually provided with three ports, one of which is a gas circulation port, and the other two ports, one is a gas-liquid mixture inlet, and the other is a liquid outlet. Specifically, the gas-liquid mixture refrigerant flows from the gas-liquid The mixture inlet enters the flash evaporator. After the gas-liquid separation in the flash evaporator, the gaseous refrigerant flows out from the gas flow port, and the liquid ref...

AI Technical Summary

Problems solved by technology

[0005] 1. After the gas-liquid mixture refrigerant enters the flash evaporator, it is impossible to determine whether the gas-liquid is completely separated. In this way, the liquid refrigerant flows into the compressor from the gas flow port for a long time, which affects the performance of the compressor and damages the compressor cylinder;

[0006] 2. For flash evaporators that require a compact structure and small space, after the gas-liquid mixture refrigerant enters the flash evaporator, when the liquid refrigerant does not flow out of the liquid flow port in time, the refrigerant in the flash evaporator will accumulate more and more, and the liquid refrigerant will flow out of the flash evaporator. The gas flow port of the evaporator enters the compressor, causing liquid shock of the compressor, which leads to damage to the air conditioning system
