Abstract

PURPOSE:To eliminate the trouble of manipulation by comparing to operate signals of the temperature setting device in a room and its temperature detection signals and switching the maximum cooling mode into the cooling mode when the difference in the signals is below the preset value. CONSTITUTION:The temperature in a car is detected with a temperature sensitive element 22. When the difference between this detection temperature and the preset temperature preset with a temperature setting device 19 is beyond the preset range, the output of a comparator 21 becomes a low level. This deenergizes a transistor 24 and does not excite a relay 25. This also permits an fan 11 to revolve at its maximum, a compressor to continuously operate, and an air mixing door 6 to be set to the maximum cooling mode. When the difference between the temperature in the car and the preset temperature is within the preset range, the output of the comparator 21 becomes a high level and the transistor 24 is energized. The compressor 3 and the air mixing door 6 are set to the cooling mode by a thermo switch 5 and a temperature controller 10, respectively.
