AIR TEMPERATURE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an air temperature control device which prevents a rise in indoor temperature and humidity during drying heating operation for removing dew condensation adhered to the surface of a heat exchanger.

SOLUTION: The air temperature control device 10 is installed under the floor or under the roof and performs cooling/heating operation for heating or cooling sucked air by the heat exchanger 13 connected to an outdoor unit 11 and supplying the air to the indoor side and dehumidification operation for lowering indoor humidity. A discharge mechanism 20 for discharging air heated by the heat exchanger 13 to outside a living room space is connected to the air temperature control device 10, and the air temperature control device 10 includes a control means 30 performing drying heating operation for evaporating dew condensation adhered to the surface of the heat exchanger 13 generated by the cooling operation or the dehumidification operation by increasing the temperature of the heat exchanger 13 and discharging the dew condensation together with the sucked air. When detecting that the cooling operation or the dehumidification operation is continuously performed for a predetermined time or longer, the control means 30 performs the drying heating operation after the completion of the continuous operation to dry the surface of the heat exchanger 13, and discharges the air heated by the heat exchanger 13 to outside the living room space via the discharge mechanism 20.
