Abstract
A hot water supply apparatus for combined use with an air conditioner is provided that may include an indoor unit having an indoor heat exchanger to heat exchange a first refrigerant with indoor air, and a cascade hot water heater connected to the indoor unit to receive the first refrigerant and to provide a second refrigerant to heat water. The cascade hot water heater may perform a heat exchange between the first refrigerant and a second refrigerant. The cascade hot water heater may include a capacity variable compressor to limit a maximum flowing amount of the second refrigerant and increase a flowing amount of the first refrigerant to flow to the indoor unit.
