AIR CONDITIONER

摘要

An air conditioning apparatus (1) has a refrigerant circuit (10) configured as a result of plural indoor units (4a, 4b) being connected to an outdoor unit (2), and the air conditioning apparatus has a capacity controlling part (81) and a target refrigerant temperature changing part (84). The capacity controlling part (81) is a part that controls the air conditioning capacity of the outdoor unit (2) in such a way that the evaporation temperature or the condensation temperature of refrigerant in the refrigerant circuit (10) becomes a target evaporation temperature or a target condensation temperature. The target refrigerant temperature changing part (84) performs slow changing control that changes the target evaporation temperature or the target condensation temperature in accordance with temperature differences between room temperatures and set temperatures and, in a case where the temperature differences have exceeded a threshold temperature difference and the number of the indoor units (4a, 4b) in operation has increased, performs fast changing control that forcibly changes the target evaporation temperature or the target condensation temperature to a fast tracking evaporation temperature or a fast tracking condensation temperature.
