Abstract
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.
