AIR CONDITIONING DEVICE

摘要

An energy saving air conditioning device. An air conditioning device configured in such a manner that, irrespective of the switched state of a first refrigerant conduit switching device (11), a second refrigerant conduit switching device (18), and an on-off device (17a), the pressure in a conduit into which a heat source-side refrigerant from an outdoor unit (1) of the second refrigerant conduit switching device (18) flows is higher than the pressure in a conduit out of which the heat source-side refrigerant flows to the outdoor unit (1).
