を特徴とするエバポレータの凍結防止装置。 A compressor control means 1 that controls the operation of a compressor that supplies refrigerant to an evaporator of an air conditioner installed in a vehicle and outputs a compressor operation signal when the compressor is activated, and detects a frozen state of the evaporator. a frozen state detection means 3 that adjusts the ratio of outside air and vehicle interior air taken in by the air conditioner;
intake ratio adjusting means 4, 5 that outputs an outside air intake signal when the ratio is adjusted so that only outside air is taken in; and the freezing state detection means that outputs an outside air intake signal when the compressor operation signal and the outside air intake signal are input. 3, when the evaporator is in a state where there is a possibility of freezing, the suction ratio adjusting means sends a predetermined ratio signal to set the ratio to a predetermined ratio that includes a predetermined amount of cabin air to outside air. 4,
5. An evaporator anti-freezing device characterized by comprising: an anti-freeze control means 2 which outputs an output to the evaporator.
