<p>PURPOSE:To effectively utilize the heat of a large quantity of waste hot water, discharged from a bathroom, as the source of heating for bath tub and feed hot water through efficient recovery of the heat of the waste hot water, by a method wherein high temperature hot water is produced by an absorption heat pump, using water, increased in temperature by the use of waste hot water, as heat source water, and hot water in the bath tub and water for feed hot water are heated by said hot water. CONSTITUTION:After waste hot water, discharged from a bathroom 1 and resulting from the use of hot water tap 2 for rinsing produced outside a tub, is stored in a tank 3, it is filtered through a hair catcher 4 and a filter 5 to pump it to a heat exchanger 7 with the aid of a pump 6. In the heat exchanger 7, the heat source water, circulated in a heat source water circulating system 9 by means of a pump 8, is exchanged with that of waste hot water to transfer the quantity of heat, possessed by the waste hot water, to the heat source water. The heat source water, increased in temperature, is fed from the circulating system 9 to an evaporator 12 of an absorption heat pump 11. Output hot water, heated by a heat input from the evaporator 12 through an absorber 13 of an absorption heat pump and a condenser 15 and the combustion heat input of a generator 14, flows through a hot water circulating system 20, having a pump 17 and heat exchangers 18, 19, back to the absorber 13 of the absorption heat pump 11.</p> |
