The present invention relates to a heat pump apparatus for a vehicle, improving a control logic of a motor-driven compressor, so as to shorten a restart time of the motor-driven compressor of a turn-off state and the responsibility of the motor-driven compressor is improved therethrough, and thereby improving temperature control quick-acting properties for an indoor space of a vehicle. To this end, in the heat pump apparatus cooling or heating the indoor space of a vehicle while being operated in a heat pump or air-conditioner mode in accordance with control a flowing direction of coolant discharged from the motor-driven compressor, and in which a revolution per minute (RPM) of the motor-driven compressor is automatically controlled in accordance with a discharge air temperature level and a target discharge temperature level inside the indoor of a vehicle, the apparatus includes a control unit restarting the motor-driven compressor in accordance with a discharge air temperature, a target discharge air temperature, and a slope of a discharge air temperature change of the indoor space of a vehicle when the motor-driven compressor is turned off in the heat pump mode, so as to shorten the restart time point of the motor-driven compressor.

    본 발명은 차량용 히트펌프 장치에 관한 것으로, 전동압축기의 제어로직을 개선함으로써, 오프(OFF)된 상태의 전동압축기 재작동 시점을 단축시킬 수 있고, 이를 통해, 전동압축기의 응답성을 개선시켜 차실내의 "온도 제어 속효성"을 향상시킬 수 있도록 하는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 전동압축기로부터 토출되는 냉매의 흐름 방향을 제어함에 따라 히트펌프 모드 또는 에어컨 모드로 작동되면서 차실내를 난방 또는 냉방하며, 차실내의 토출공기온도와 목표토출온도의 크기에 따라 상기 전동압축기의 회전수가 자동 제어되는 차량용 히트펌프 장치에 있어서, 히트펌프 모드 시에 전동압축기가 정지(OFF)된 상태에서, 차실내의 토출공기온도와 목표토출온도와 토출공기온도 변화 기울기에 따라 전동압축기를 재작동시켜, 전동압축기의 재작동 시점을 단축시키는 제어부를 구비한다.
