AIR CONDITIONING DEVICE

摘要

An energy saving air conditioning device. An air conditioning device (100) is configured in such a manner that, even if the switched state of a first refrigerant conduit switching device (11) changes, the pressure of a heat source-side refrigerant within bypass piping (4d) is switched between high and low by a second refrigerant conduit switching device (18) and a third refrigerant conduit switching device (on-off device (17)).
