PURPOSE: A vehicle cooling control device using the rpm of a compressor for control is provided for efficient cooling by adjusting opening quantity of an expansion valve according to the PRM of a compressor. CONSTITUTION: A vehicle cooling control device using the rpm of a compressor for control comprises a compressor, a condenser, an expansion valve, an evaporator, and a control unit. The compressor is rotated by an engine and compresses and exhausts coolant. The expansion valve expands the coolant passing through a condenser. The expansion valve is composed of an electronic expansion valve capable of adjusting the opening and the opening quantity is controlled according to the abnormal heating state set to be matched to the RPM of the compressor based on set values. |
