Abstract

PURPOSE:To automate the cooling temperature control and to prevent an evaporator from freezing, by controlling the running of a compressor of the captioned cooler by the change in a car interior temperature within a set temperature range and by a set evaporator outlet temperature that will be varied by the number of revolutions of an engine. CONSTITUTION:The car interior temperature is set by a variable resistor 24. When the car interior temperature is above T2, the resistance of a car interior temperature detecting element 23 falls and the output of an amplifier 28 becomes high level, and when the temperature of an evaporator outlet temperature detecting element 11 exceeds T3, an electromagnetic clutch 6 is turned on by the output of an amplifier 18, an when it is below T3 the electromagnetic clutch is turned off. In this case, the negative side input of the amplifier 18 is decreased when the number of revolutions detected by an engine revolution number detector 71 is small, an it is increased when the number is high. Thus, when the evaporator outlet temperatures T3, T4 at which the electromagnetic clutch 6 is turned off according to the number of revolutions of the engine is suitably set, the evaporator is prevented from freezing, and the running of the compressor can be suitably and automatically controlled.
