Description
図1に示すように、本実施形態の空気調和機1は、室内に設置される室内機2と、室外に設置される室外機3とを備えている。そして、空気調和機1は、圧縮機10と、四方弁11、室外熱交換器12と、膨張弁13と、室内熱交換器14とを接続した冷媒回路を備えている。冷媒回路において、圧縮機10の吐出口に四方弁11を介して室外熱交換器12が接続され、その室外熱交換器12に膨張弁13が接続される。そして、膨張弁13に室内熱交換器14の一端が接続され、その室内熱交換器14の他端に四方弁11を介して圧縮機10の吸込口が接続される。室内熱交換器14は、補助熱交換器20と、主熱交換器21とを有している。
本実施形態の空気調和機1では、除湿運転開始操作が行われたときに負荷が大きい場合、冷房運転でも熱交換器の温度が低いため、十分な除湿が可能であるので、冷房運転を開始することで、効率良く、除湿と冷房を同時に行うことが可能である。そして、室内の温度が低下して、負荷が小さくなってくると、冷房運転では、蒸発温度が高くなって除湿できなくなるため、その時点で除湿運転に切り換える。これにより、除湿のためのCOP悪化の影響を最小限とすることが可能となる。
