Abstract (en)
An air-conditioning/hot water-supply system that, even if a condensation temperature Tvc in a refrigeration cycle in which an air-conditioning refrigerant circulates varies, prevents a durability of a hot water-supply compressor from being impaired, enabling enhancement in reliability, is provided. A volume ratio between a low pressure-side circuit internal volume Ve and a high pressure-side circuit internal volume Vc in a first refrigeration cycle 100 is set as Ve/Vc = 0.2 to 10.1. Consequently, irrespective of a condensation temperature Tvc in a second refrigeration cycle, no excessive increase in discharge temperature Td of the first refrigeration cycle occurs and thus a durability of a compressor is not impaired, enabling enhancement in reliability of the first refrigeration cycle.
