Title:
HEAT PUMP SYSTEM
Document Type and Number:
Japanese Patent JP3430639
Kind Code:
B2
Abstract:
PURPOSE: To make it possible to boil up at high speed with high efficiency without being affected by an outdoor temperature by installing at least a reboiling heat exchanger and a hot water supply heat exchanger connected therewith and reboiling with the heat of high temperature water stored in a hot water storage tank.
CONSTITUTION: A heat pump system is designed to perform at least either cooling or heating operation by means of an indoor heat exchanger 6 and an outdoor heat exchanger 16 connected to a compressor 1. In this system, a reboiling heat exchanger 13 is installed to a reboiling unit 12 so as to heat circulation water to be supplied to a bath tub 15 by a heat exchange with the refrigerant discharged from the compressor 1. On the other hand, a hot water supply heat exchanger 8 is connected to the reboiling heat exchanger 13 in order to heat-exchange refrigerants with the high temperature water in a hot water storage tank 10 which is circulated with a hot water supply pump 9 in a hot water supply unit 7. Reboiling operation is carried out, using the heat of the high temperature water stored in the hot water storage tank 10. This construction makes it possible to reboil with the heat of hot water and, what is more, to reboil with high efficiency and at high speed without being affected by an outdoor temperature.
