たことを特徴とする自動車用冷房装置。 In an automobile cooling system, the refrigerant gas compressed by a compressor is liquefied with heat dissipation in a condenser, adiabatically expanded in an electric expansion valve, and then heat exchanged in an evaporator and returned to the compressor. The control circuit includes a control circuit that once fully closes the valve to perform valve opening reference point setting control, and then controls the start of operation of the compressor and starts valve opening control of the electric expansion valve to a normal valve opening. An automobile cooling device characterized by:
