Disclosed therein are a heat pump system for a vehicle and a method of controlling the heat pump system, which variably controls only a compressor if the number of revolutions of the compressor is less than the upper limit of the number of the maximum revolutions of the compressor and operates an electric heater only when the number of revolutions of the compressor reaches the upper limit of the number of the maximum revolutions of the compressor in order to satisfy a target discharge temperature in a heat pump mode, thereby preventing that convergence of an air discharge temperature of the interior of the vehicle is deteriorated or becomes unstable when the compressor and the electric heater are variably controlled at the same time in order to satisfy the target discharge temperature.

Heat pump system for vehicle and method of controlling the same

The present invention relates to a method for controlling a vehicle air-conditioner, which can prevent undershoot of an evaporator by performing a maximum capacity control or controlling an discharge capacity of a compressor through the outputting of an discharge capacity control value of the compressor directly before the stop of the air conditioner, and can improve the pleasant feelings of the passengers by preventing delay of response, which converges into the target temperature of the evaporator due to the delay of the decrease of the temperature of the evaporator.
