Title:
COMBINED SYSTEM OF AIR CONDITIONING DEVICE AND HOT-WATER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/113372
Kind Code:
A1
Abstract:
A combined system of an air conditioning device and a hot-water supply device, the system being provided with: an air conditioning refrigeration cycle comprising a heat source unit (A), an indoor unit (B), a hot-water supply heat source circuit (D) provided with a refrigerant-to-refrigerant heat exchanger (41) and a flow restriction 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, the indoor unit and the hot-water supply heat source circuit being connected parallel to each other, the air conditioning refrigeration cycle being connected, using at least two lengths of connection piping (106, 107), to the heat source unit through the branch unit; and a hot-water supplying refrigeration cycle formed by connecting in series a hot-water supplying compressor, a heat medium-to-refrigerant heat exchanger, a flow restriction means for hot water supply, and the refrigerant-to-refrigerant heat exchanger. The air conditioning refrigeration cycle and the hot-water supplying refrigeration cycle are connected in such a manner that an air conditioning refrigerant and a hot-water supplying refrigerant are subjected to heat exchange by the refrigerant-to-refrigerant heat exchanger.
