Title:
AIR CONDITIONER EQUIPPED WITH REFRIGERATOR FOR CAR
Document Type and Number:
Japanese Patent JPS6253217
Kind Code:
A
Abstract:
PURPOSE:To suppress the temperature rise of the cooling wind by shortening the coolant shielding time of an evaporator for air conditioning by allowing coolant to flow alternately in the evaporator for air conditioning and an evaporator for refrigerator and allowing the refrigerator function to be compatible with the air conditioning function. CONSTITUTION:If the ignition switch 31 of a car engine and a cooler switch 32 are turned-ON, a compressor 10 is operated by the electric conduction of an electromagnetic clutch 1 through a clutch control circuit 38, and the refrigeration cycle of an air conditioner for car operates. If a switch 33 for refrigerator is turned-ON at the first operation position 33b at this time, an input signal is supplied into the first input terminal A of a pulse generating circuit 34a of a refrigerator control circuit 34 through an OR circuit 37, and a refrigerator blower 25 operates. At the same time, the electric conduction of a solenoid valve 14 is connected and disconnected by the pulse output of the above- described circuit 34a, and coolant flows alternately in an evaporator for air conditioning and an evaporator for refrigerator, accompanied by the opening and closing of the solenoid valve 14.
