Abstract
PURPOSE:To prevent unnecessary operation of a compressor by turning the compressor off when the temperature of outside air is below the upper-limit value of the temperature of the outside air at which motive power is saved and the rotary angle of a mixing door is large. CONSTITUTION:The outside-air temperature t1 allowing the lowest operation of the compressor 13 and the upper-limit value t2 of the outside-air temperature allowing the power saving, which is hight than the temperature t1 and at which the power can be saved when the compressor 13 is stopped, are set before hand. When the outside-air temperature reaches t1 or t2 (a region of the temperature at which the power can be saved), a contact point 101 turns on, while a contact point 111 turns off. When the rotary angle of the mixing door 1 is larger than a set level at this time, the device is under the condition of blowing warm air, and thus it is unnecessary to send cooled air into a car room. Therefore, a contact point 121 turns off and the compressor 13 is not driven.
