Air conditioning apparatus

摘要

An air conditioning apparatus has a refrigerant circuit made up of plural indoor units connected to an outdoor unit, and the air conditioning apparatus has a capacity controlling part and a target refrigerant temperature mode setting part. The capacity controlling part controls the air conditioning capacity of the outdoor unit in such a way that the evaporation temperature of refrigerant in the refrigerant circuit becomes a target evaporation temperature, or in such a way that the condensation temperature of the refrigerant becomes a target condensation temperature. The target refrigerant temperature mode setting part is configured to seta target refrigerant temperature mode to either a target refrigerant temperature changing mode or a target refrigerant temperature fixing mode. The target refrigerant temperature changing mode changes the target evaporation temperature or the target condensation temperature, and the target refrigerant temperature fixing mode fixes the target evaporation temperature or the target condensation temperature.

1. An air conditioning apparatus equipped with a refrigerant circuit configured with plural indoor units connected to an outdoor unit, the air conditioning apparatus comprising:
a capacity controlling part controlling an air conditioning capacity of the outdoor unit such that an evaporation temperature of refrigerant in the refrigerant circuit becomes a target evaporation temperature; and a target refrigerant temperature mode setting part setting a target refrigerant temperature mode to one of
a target refrigerant temperature changing mode that changes the target evaporation temperature, anda target refrigerant temperature fixing mode that fixes the target evaporation temperature, the target refrigerant temperature changing mode having
a first changing mode that changes the target evaporation temperature in such a way that room temperatures of air conditioned spaces targeted by the indoor units reach set temperatures that are target values of the room temperatures in an amount of time, anda second changing mode that changes the target evaporation temperature in such a way that the room temperatures reach the set temperatures in a longer amount of time than in the first changing mode, and the first changing mode and the second changing mode being set by the target refrigerant temperature mode setting part.
