ABSTRACT:
An air conditioning apparatus comprising an indoor unit. The unit has a first indoor heat exchanger for cooling or heating indoor air and a second indoor heat exchanger for cooling or heating indoor air. A first indoor fan is located near the first indoor heat exchanger, for drawing the indoor air and supplying it through the first indoor heat exchanger to the zone of a room. A second indoor fan is located near the second indoor heat exchanger, for drawing the indoor air and supplying it through the second indoor heat exchanger to the zone of a room. The apparatus further comprises two temperature sensors for detecting the temperatures of the indoor heat exchangers, respectively. The higher or lower of the temperatures detected by the sensors is selected, in accordance with the cooling or heating mode in which the apparatus is operating. In accordance with the temperature selected, the air-supplying rates of the indoor fans are controlled.
