Liquid separator and air conditioning system with same

The utility model provides a liquid separator and an air conditioning system with the same. The liquid separator includes: a housing including an air inlet portion; one end of the first pipeline extends into the shell, and the other end of the first pipeline is communicated with an air inlet of the compressor; the second pipeline is communicated with an air inlet of the compressor; the second pipeline is made of a heat insulation material or a heat insulation coating is arranged on the outer surface of the second pipeline; the switch structure is arranged at the air inlet part and has a firstworking state for controlling the air inlet part to be communicated with the first pipeline and a second working state for controlling the air inlet part to be communicated with the second pipeline; the detection device is used for detecting real-time state parameters of the compressor and the liquid separator so as to obtain the state of a refrigerant entering the air inlet part through the real-time state parameters, an
