PURPOSE: To reduce the change of temperature of the humidity sensitive element of a humidity sensor and minimize a deviation between a set humidity and an indoor humidity by a method wherein an operation control device, having a temperature sensitive element and a humidity sensitive element, is provided with a timer function to stop a fan for a predetermined period of time after outputting the output signal of finishing of dehumidification and the device is constituted so as to reopen the operation of the fan preferentially in separating from the operation of a compressor.
CONSTITUTION: In case of a normal room temperature of 15W40°C, the temperature of the temperature sensitive element becomes high and defrosting starting output is not outputted, therefore, the compressor 11 and the fan 12 are operated. When the dehumidification finishing output is outputted by the humidity detection of the humidity sensitive element 20, the compressor 11 and the fan 12 are stopped. Subsequently, the compressor 11 starts the operation by dehumidification starting output, however, the fan 12 only is started preferentially and the operation of the compressor is started after a predetermined period of time (t). The indoor humidity detection of the humidity sensitive element is effected correctly by utilizing the ventilation of the fan 12 and, then, the dehumidifying operation is reopened.
