COOLING SYSTEM FOR HYBRID VEHICLE AND CONTROL METHOD THEREOF

摘要

PURPOSE: A hybrid vehicle air conditioning device and a control method thereof are provided to improve the air conditioning function by securing a long valid cooling time in an ISG mode. CONSTITUTION: A hybrid vehicle air conditioning device comprises a valve way and a controller(7). The valve way controls a refrigerant, flowing in an evaporator(1), to isolates the evaporator from an expansion valve(3) and compressor(5). The valve way comprises a first solenoid valve(9) and a check valve(11). The first solenoid valve is controlled by the controller and blocks the refrigerant flowing between the evaporator and the expansion valve. The controller controls the valve member according to cooling conditions in idle stop and isolates the evaporator from the expansion valve and compressor.
