Background
In an air conditioning system, a compressor compresses only gaseous refrigerant, which can cause damage to the compressor and system rejection if liquid refrigerant is drawn into the compressor in large quantities. Therefore, in the prior art, a gas-liquid separator is often installed between the evaporator and the compressor. The working principle of the gas-liquid separator is as follows: the gas-liquid two-phase refrigerant from the evaporator enters the gas-liquid separator, the liquid refrigerant sinks under the action of gravity, and the gaseous refrigerant rises; the gas-liquid separator is internally provided with a low-temperature low-pressure pipeline, the outlet end of the low-temperature low-pressure pipeline is communicated to the outside of the gas-liquid separator, the opening of the inlet end of the low-temperature low-pressure pipeline is exposed to the inner cavity at the upper part of the gas-liquid separator, and rising gaseous refrigerant flows to the outlet end through the inlet end and then enters the compressor. The prior gas-liquid separator comprises a body, a low-temperature low-pressure input pipe, a low-temperature low-pressure output pipe and a high-temperature high-pressure pipeline which exchanges heat with the refrigerant input by the low-temperature low-pressure input pipe. The low-temperature low-pressure gaseous refrigerant from the evaporator is subjected to heat exchange through the high-temperature high-pressure pipe, so that the gaseous refrigerant in a subcritical state at the inlet of the compressor is overheated, and the liquid refrigerant in a supercritical state before throttling is supercooled, thereby obviously improving the efficiency of a transcritical refrigerant refrigeration cycle system, reducing the exhaust pressure required by the optimal performance of the system, avoiding the occurrence of liquid impact of the compressor and the like. The defects are that: the high-temperature high-pressure pipe of the gas-liquid separator has low heat exchange efficiency on the low-temperature low-pressure gaseous refrigerant coming out of the evaporator.
