AIR CONDITIONING DEVICE

摘要

An air-conditioning apparatus capable of achieving energy saving is provided. In the air-conditioning apparatus 100, even when a switching state of a first refrigerant flow switching device 11 varies, a pressure state of a heat source side refrigerant in a bypass pipe 4d is switched between high and low pressures by second refrigerant flow switching devices 18 and a third refrigerant flow switching device (on-off device 17).
