Abstract:
This air conditioning system (1) constitutes a multi-source refrigeration cycle including a heat source-side circuit (10) and a use-side circuit (30). The heat source-side circuit (10) has a heat source-side compressor (21), an outdoor heat exchanger (23) that exchanges heat between a heat source-side refrigerant and outdoor air, and a refrigerant-refrigerant heat exchanger (25) that exchanges heat between the heat source side refrigerant and a use-side refrigerant. The use-side circuit (30) has a use-side compressor (31), a refrigerant-refrigerant heat exchanger (25), and a plurality of indoor heat exchangers (52) that exchange heat between the use-side refrigerant and indoor air, and carbon dioxide is enclosed as the use-side refrigerant. The amount of the use-side refrigerant enclosed in the use-side circuit (30) is 7.9 kg or less.
