Abstract
An air conditioning system according to the present invention changes a target supply temperature based on a magnitude relationship between an operating frequency of a first compressor and a first frequency at which an operating efficiency of the first compressor reaches a maximum, and a magnitude relationship between an operating frequency of a second compressor and a second frequency at which an operating efficiency of the second compressor reaches a maximum.
