Abstract

PURPOSE: To enhance efficiency at the time of room cooling and to supply hot water without using a hot water storage tank by composing of a first refrigerating cycle, a second refrigerating cycle and a room cooling/heating cycle.
CONSTITUTION: A compressor 2, a four-way valve 3, a brine side heat exchanger 4, an expansion valve 5 and an air side heat exchanger 6 are sequentially connected, refrigerant R22 is sealed to form a first refrigerating cycle 1. A compressor 8, a water side heat exchanger 9, an expansion valve 10, and a brine side heat exchanger 11 are sequentially connected to form a second refrigerating cycle 7 sealed with nonazeotropic refrigerant made of refrigerants R22 and R123. A brine tank 13 containing heat exchangers 4, 11, a four-way valve 14, a circulation pump 15, and an indoor heat exchanger 16 are sequentially connected to form a room cooling/heating cycle 12. With this structure, brine is cooled by the exchanger 4 for forming the first refrigerating cycle at the time of room cooling, circulated to the room cooling/heating cycle to cool the interior in the room. At the time of room heating, the brine is heated by the exchanger 4, circulated to the cycle to heat the interior in the room. On the other hand, at the second refrigerating cycle side, city water is heated by the exchanger 9 to supply hot water.
