AIR CONDITIONING SYSTEM

WIPO Patent Application WO/2023/276584

A1

An air conditioning system 100 is provided with: an outdoor unit 110 having a heat-source-side refrigerant circuit RC1; a plurality of indoor units 120 having respective indoor heat exchangers 52; switching units 70 having respective intermediary refrigerant circuits RC3; and a first heat recovery unit 130 having a first auxiliary refrigerant circuit RC2 that includes an intake-side auxiliary heat exchanger 131 and an exhaust-side auxiliary heat exchanger 132. The heat-source-side refrigerant circuit RC1 and each of the intermediary refrigerant circuits RC3 are connected to each other by a first connection pipe 11 through which a liquid refrigerant flows, a second connection pipe 12 through which a high-pressure gas refrigerant flows, and a third connection pipe 13 through which a low-pressure gas refrigerant flows. The heat-source-side refrigerant circuit RC1 and the first auxiliary refrigerant circuit RC2 are connected to each other by the second connection pipe 12 and the third connection pipe 13 via an auxiliary heat exchanger switching valve 133.
