PURPOSE:To improve the rate of operation of a compressor, by providing two connections of an A/C switch and an ECO switch in a magnet clutch actuating switch of the compressor and constituting an equipment so as to control a preset temperature and a mixing door to be changed by proper use of the switches. CONSTITUTION:When large room cooling power is necessary, an A/C switch 201 is controlled to switch a switching circuit 21 to a position of A/C, and a compressor is operated to the maximum rate of operation by controlling a setting lever 221 and a magnet clutch 30 by an evaporator temperature 19. When no large room cooling power is required, an ECO switch 203 is controlled to switch the circuit to a position of ECO and decide by an outside air temperature decision circuit 24 an outside air temperature level 25, and if it is not less the preset temperature, an air mixing damper 17 is fixed to a position of cold, and the magnet clutch 30 is controlled by the detection temperature 19. If the temperature is in a value not more than the preset temperature, a mixing door is actuated by a temperature setter 22, and the compressor is on-off controlled. By this constitution, the rate of operation of the compressor is improved. |
