PURPOSE:To exactly prevent the lowering of humidity by operating a compressor at and around the freezing limit of an evaporator when the humidity inside the car room is below the specified value, and reducing the discharge capacity of the compressor when the reheat quantity of the cooling air is above the specified value. CONSTITUTION:An instruction signal is output by a means 103 so that the suction air temperature may be the specified temperature being determined by the freezing start temperature of an evaporator when the outside air temperature is above the specified value. Moreover, the reheat quantity of the air being cooled by the evaporator is adjusted by a means 104 so that the reheat quantity may decrease if the suction air temperature rises when the target blowoff temperature is fixed, based on the deviation between the suction air temperature and the target blowoff temperature. And when the humidity inside the car room detected by a means 106 is below the specified value, if the reheat quantity detected by a means 105 is above the specified valve and besides the said instruction signal is output, a capacity changing means 102 is controlled by a means 107 so that the discharge capacity of a variable capacity compressor 101 may decrease. |
