A device for controlling a compressor of vehicles may include a sensor module including a cabin temperature sensor, an outdoor temperature sensor, an evaporator temperature sensor detecting a temperature of cooling medium in an evaporator, a vehicle speed sensor, and a brake sensor, an injector, an air conditioning system including a condenser, an evaporator, the compressor, a temperature control door controlling a temperature of air flowing into a cabin, an intake door selectively distributing an inner air or an outer air into the cabin, and a blower blowing the air to the intake door, and a controller controlling the injector and the air conditioning system, wherein the controller accumulates a cold air energy by increasing an operation of the compressor if a speed-reducing condition occurs, and the air conditioning system uses the accumulated cold air energy by decreasing the operation of the compressor if a release condition occurs.

Device and method for controlling compressor of vehicles to accumulate cold air energy in an evaporator during a speed-reducing condition and using the latter in a release condition

A coolant circulation system for turbochargers is provided. The coolant circulation system includes a turbocharger provided with a coolant outlet line and a coolant inlet line. The coolant is discharged from the turbocharger through the coolant outlet line. The coolant outlet line is connected to a first flow path connecting an inlet port of a radiator to an outlet port of a heater core. The coolant is supplied into the turbocharger through the coolant inlet line. The coolant inlet line is connected to a second flow path connecting a first end of a water pump to an inlet port of the heater core.

An automatic defogging system of a vehicle according to an exemplary embodiment of the present invention includes: an input unit used for receiving a directly sensed window relative humidity value from a defogging sensor so as to directly sense a humidity generation degree in a window; a controller which controls operations of an air conditioning system programmed as a type of a logic that is selectively and phasedly controllable depending on the sensed relative humidity and; an output unit that is a selection mode of the air conditioning system that can be controlled by the controller. Accordingly, an automatic defogging system of a vehicle and a control method thereof automatically removes fog or frost on an inner surface of a window while maintaining comfortable conditions inside a vehicle.
