<p>PURPOSE:To improve thermal efficiency by a method wherein a hot-water system is consisting of a heat radiating hot-water system, whose temperature corresponds to the temperature of hot- water supplied to respective radiators, and a hot-water supplying system, whose temperature corresponds to the temperature of supplying hot water, while the internal-combustion engine and a heat pump are utilized for the heat source for the heat radiating hot-water system. CONSTITUTION:The heat radiating hot-water system C is constituted of a waste heat retrieving hot-water system A, retrieving the waste heat of the internal-combustion engine 1, a heat pump hot-water system B, passing through the condenser 3 of the heat pump 6 employing a compressor 2 utilizing the internal-combustion engine 1 as a driving source, and a heat exchanging section 8, utilizing the hot-water of the system B and the system A as the heat source. A heat radiating system D, communicating with a proper radiator 10, is connected to the system C and a hot-water supplying system E, from a water supplying section 12 to the hot-water dischrging section 14 through the indirectly coupled heat exchanging section 8 and an auxiliary boiler 13, is constituted. Thus, the improvement of the property of installation, reduction of radiating heat loss from a hot-water reserving tank, improvement of comfortable property and the improvement of the efficiency of the heat pump are contrived and the thermal efficiency may be improved remarkably as a whole.</p> |
