Multiroom air conditioner and control method therefor

摘要

The dehumidifying performance is enhanced. In dehumidifying operation, the air stream feel and cold wind feel for the inhabitants are suppressed. Dew condensation is prevented around the diffuser of the indoor unit. The individual temperature controllability of each indoor unit is excellent. The cost performance is excellent and it is inexpensive. A multi-room air conditioner includes one outdoor unit and a plurality of indoor units connected to the outdoor unit. In each indoor unit, the target control temperature is set and stored. Of the target control temperatures of the individual indoor units, in order to set the highest target control temperature at the control piping temperature, a control piping setting circuit is provided. The capacity of the compressor is controlled by comparing the control piping temperature and the piping temperature of the indoor unit adopted as the control piping temperature.
