摘要： An air-conditioning apparatus includes an outdoor unit including a compressor configured to compress refrigerant, a relay unit connected to the outdoor unit, and an indoor unit connected to the relay unit. The compressor is driven to circulate the refrigerant between the outdoor unit, the relay unit, and the indoor unit. The air-conditioning apparatus includes a supplementary heat source unit in parallel with the indoor unit and connected to the relay unit. The outdoor unit includes an outdoor heat exchanger configured to exchange heat between the refrigerant flowing through the outdoor heat exchanger and a fluid. The supplementary heat source unit includes a supplementary heat exchanger configured to exchange heat between the refrigerant flowing through the supplementary heat exchanger and hot water.

摘要： An air conditioning system (1000) comprises one or more air conditioners (100) through which refrigerant circulates, and a first controller (1). For each of one or more indoor units (20), a score corresponding to a cost of using the indoor unit (20) is preset. The first controller (1) calculates, for each of the one or more air conditioners (100), a first total value of a score of each of the one or more indoor units (20) included in the air conditioner (100). The first controller (1) calculates a second total value of the first total value of each of the one or more air conditioners (100). When an electrical energy limit condition is satisfied, the first controller (1) sets for each of the one or more air conditioners (100) a drive frequency for a compressor (11) included in the air conditioner (100) according to a ratio of the first total value of the air conditioner (100) to the second total value.
