Abstract

MULTI-SPLIT AIR CONDITIONING APPARATUS Condensation in the rotor of an indoor fan is reduced when a multi-split air conditioning apparatus performs a low-capacity cooling operation. At least one indoor unit among a 5 plurality of indoor units (40, 50, 60) is configured to, when an indoor temperature is higher than a set temperature during the low-capacity cooling operation which increases an superheat region more than during a normal cooling operation, increase an opening degree of an indoor expansion valve (41, 51, 61) to thereby narrow the superheat region so as to expand a wet region of an indoor heat exchanger (42, 52, 62) and increase flow rate of the indoor fan 10 (43, 53, 63).
