The invention relates to a two-position five-way valve and an electrombile air conditioning system. The two-position five-way valve comprises a tubular valve body, a first flange, a second flange and a pilot valve, wherein the first flange and the second flange are arranged at two ends of the valve body, the first flange, the second flange and the cavity body form a containing cavity, and a piston is arranged in the containing cavity and separates the containing cavity into a first cavity and a second cavity. A first capillary tube is arranged in the first flange, the second flange is provided with a second capillary tube, and the valve body is provided with a first joint, a second joint, a third joint, a fourth joint and a fifth joint. A third first capillary tube is fixed on the first joint, a fourth capillary tube is fixed on the third joint, and the pilot valve comprises a holding cavity provided with a control member for controlling connection and disconnection of the first joint, the second joint, the third joint, the fourth joint and the fifth joint. The two-position five-way valve can achieve reliable switch between refrigeration and heating of a traditional electrombile air conditioning system to simplify the structure of the air conditioning system and reduce cost of the system.
Description
technical field [0001] The invention relates to the technical field of air conditioning, and more specifically relates to a two-position five-way valve and an electric vehicle air conditioning system. Background technique [0002] The principle of common electric vehicle air conditioning system is as follows: figure 1 As shown, it includes an electric compressor 1, an external heat exchanger 7, an in-vehicle evaporator 8, an in-vehicle heater 9, a first thermal expansion valve 2, a second thermal expansion valve 3, a first solenoid valve 5, a second The solenoid valve 6, the third solenoid valve 10 and the fourth solenoid valve 4 also include electric heaters and blowers. When the air conditioning system is cooling, the refrigerant flowing out from the electric compressor 1 passes through the first electromagnetic valve 5, the external heat exchanger 7, the second electromagnetic valve 6, and the first thermal expansion valve 2 according to the flow direction indicated by t...
