Through the parallel combination of electronic expansion valve and solenoid valve, the combined valve is generally used to switch the full circulation and throttling functions (corresponding to the switching of refrigeration and heating functions) in the automotive heat pump system. Employing the combined valve can reduce the system pipelines and connection points and decrease the overall system cost. It is widely used in the automotive heat pump system .
