DescriptionIn ordinary cars, the mechanical water pump mounted on the engine for heating purposes is activated to circulate the cooling water, but in hybrid cars, AEWP is used to circulate the cooling water when the engine is not operating.
DescriptionThe evaporator temperature sensor will detect the evaporator core temperature and interrupt compressor relay power in order to prevent evaporator from freezing by excessive cooling. The evaporator temperature sensor has the Negative Temperature Coefficient (NTC).
