<p>PURPOSE: A freezing preventing method is provided to secure the normal operation of an evaporator by heating an evaporator compulsively in case the evaporator is frozen. CONSTITUTION: A freezing preventing method is as follows. The temperature of an evaporator is detected while cooling(S10). The maintaining time of the temperature of an evaporator lower than determined temperature is detected(S20). The heating for an evaporator is determined(S30). The operation of a compressor is stopped while heating an evaporator(S50).</p> |
