Abstract

An air conditioning apparatus 100 comprises an outdoor unit 10 including a compressor 1, an outdoor heat exchanger 3 and an expansion valve 5, and an indoor unit 20 including an indoor heat exchanger 6, an indoor fan 7, a sucked-in indoor air temperature sensor 31 and a controller 30 to control the rotation speed of the indoor fan. If an air temperature difference Î T between the sucked-in air temperature Tin and a set temperature Tset is greater than a thermo-threshold, the controller determines the number of revolutions per minute Nf for the indoor fan. If the air temperature difference Î T exceeds a fan threshold T2, a heat exchanger temperature Te exceeds a coolwarm threshold T3, and an air humidity Hin is lower than a dry-wet threshold H1, the controller stops the indoor fan. After the indoor fan has been stopped, if a supercooling temperature Î Tedp, which is a difference between the heat exchanger temperature Te and a dew-point temperature Tdp, is lower than a supercooling threshold T4, or if a re-rotation period has elapsed since the stop of the indoor fan, the controller rotates the indoor fan again. The aim of the invention is to achieve dehumidification and prevent freezing of the indoor heat exchanger.
