INITIAL COOLING DEVICE OF AIR CONDITIONER

摘要

PURPOSE: An initial cooling device of air conditioner is provided to swiftly cool down a car room by improving heat efficiency on initial stage of re-operation of the air conditioner by storing refrigerant in a receiver dryer with capacity larger than usual even when a vehicle stops. CONSTITUTION: A receiver dryer(4) with large capacity having a manometer(401) is installed between an evaporator(3) and a compressor(1). Solenoid valves(5,6) are installed on both sides of the receiver dryer. A bypass line(7) is connected with the solenoid valves. A controller is connected with the solenoid valves to actuate the solenoid valves according to signals of a velocity sensor connected to the controller to control the receiver dryer.
