<p><P>PROBLEM TO BE SOLVED: To prevent generation of dew condensation even when a heat pump cooling operation by operating an air conditioner and an outside air cooling operation only by introducing the outside air are alternately switched. <P>SOLUTION: This air conditioning device includes the air conditioner 1 having a compressor, constituting a refrigerating cycle, and cooling and supplying the sucked air, a duct 8 for guiding the indoor air to the air conditioner, an air intake damper 6 controlling the inflow of the indoor air to the duct, an outside air damper 7 controlling inflow of the outside air indoors, and an outside air temperature sensor 3. This air conditioning device has a heat pump operation mode for cooling a room by the heat pump operation, and an outside air cooling mode for introducing the outside air indoors by controlling the air intake damper and the outside air damper, and cooling the room. When the outside air temperature is lowered, and the device is switched from the heat pump operation mode to the outside air cooling mode, a frequency of the compressor is lowered, a supply temperature is raised, and then the outside air is introduced indoors. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
