Abstract:
PURPOSE:To obtain the above heat pump type hot-water supplier, capable of supplying high-temperature hot-water efficiently and provided with air- conditioning function. CONSTITUTION:The subject hot-water supplier is a binary refrigerating system consisting of two sets of refrigerant circuits 1, 2 of a middle-temperature middle pressure and high-temperature high pressure while supplying hot-water is preheated by the second condensing liquefier 14 of the refrigerant circuit 1 of the side of a low stage. According to this method, the compression ratio of respective refrigerant circuits can be reduced whereby hot-water supplying performance is improved and high-temperature supplying hot-water can be obtained. On the other hand, the low stage side refrigerant circuit 1 is provided with a refrigerant distributing device 12, a four-way valve 17, an indoor heat exchanger 18 and a choke device 19 whereby not only the supplying of hot-water, but also the cooling and heating of a room can be effected by the subject hot-water supplier.
