<P>PROBLEM TO BE SOLVED: To provide a combined system of an air conditioning device and a hot-water supply device achieving convenience, comfort and energy-saving by simultaneously and stably providing air-conditioning (heating or cooling) and hot-water supply. <P>SOLUTION: This combined system of the air conditioning device and the hot-water supply device includes a refrigeration cycle for air conditioning, including a heat source machine A, an indoor unit B, a hot-water supply heat source circuit D provided with a refrigerant-to-refrigerant heat exchanger 41 and a throttle means 119 for a hot water supply heat source, and a branch unit C for dividing a refrigerant flowing to the indoor unit and the hot-water supply heat source circuit in a state of connecting the indoor unit to the hot-water supply heat source circuit in parallel, and connected with the heat source machine by at least two connection pipes 106, 107 through the branch unit, and a hot-water supply refrigeration cycle formed by connecting a hot-water supply compressor, a heat medium-to-refrigerant heat exchanger, a throttle means for hot water supply, and the refrigerant-to-refrigerant heat exchanger in series. The air conditioning refrigeration cycle and the hot-water supply refrigeration cycle are connected in such a manner that an air conditioning refrigerant and a hot-water supply refrigerant are subjected to heat exchange by the refrigerant-to-refrigerant heat exchanger. <P>COPYRIGHT: (C)2011,JPO&INPIT |
