Air conditioner for vehicle

Abstract

Abstract PURPOSE: To quickly get rid of dew condensation of an air conditioner for preventing mist on an inner gress, by controlling operation of a compressor and quantity of intake-air and exhaust air, by means of a rear heat ray on-mode signal and an open air detecting signal. CONSTITUTION: When mist is generated, a demist switch 24 1 or a rear heat ray control switch 24 2 is turned on. And when the outdoor temperature t a sensed by a sensor 82 is higher than the set temperature t 1 , an electromagnetic clutch 65 is switched on, causing the compressor to enter on-mode and 30 percent of the open air is led into a car. On the other hand, when the set time passes, the input from rear heat ray 50 is cut off. When the outdoor temperature t a is lower the set temperature t 1 , 100 percent of the open air is led into the car, then when the set time passes, a blower 12 is powered on and air flow is increased. In this way, mist is prevented, and dew condensation is quickly removed while the power consumption of heat ray can be saved. COPYRIGHT: (C)1982,JPO&Japio
