SOLAR HEATING SYSTEM HAVING A HEATING TANK AND A TANK FOR SUPPLYING HOT WATER SEPARATED FROM EACH OTHER

摘要

The present invention relates to a solar heating system in which a thermal storage tank for heating and a thermal storage tank for supplying hot water are separated from each other to efficiently use stored heat and optimize installation space for the system. The solar heating system comprises a solar heat collector, a thermal storage tub for storing heat collected by the solar heat collector, and an auxiliary boiler operated when the stored heat of the thermal storage tub is insufficient. The heat storage tub has a thermal storage tub for heating and a thermal storage tub for supplying hot water which are separate from each other, wherein the thermal storage tub for supplying hot water is disposed on the thermal storage tub for heating. A first stored heat exchanger, which is connected to the heat collecting pipe of the solar heat collector through the medium of a first three-way valve, is installed in the thermal storage tub for supplying hot water. A second stored heat exchanger, which is connected to the first three-way valve and the water-outflow tube of the first stored heat exchanger through the medium of a second three-way valve, is installed in the thermal storage tub for heating. An auxiliary heat exchanger supplying hot water is installed in the thermal storage tub for heating, wherein the pipe entrance and the pipe exit of the auxiliary heat exchanger are extended so as to be led into the thermal storage tub for supplying hot water. The tube for hot water outflow of the thermal storage tub for heating is selectively connected to the auxiliary boiler or a heating pipe through the medium of a third three-way valve. The hole for exchanging water of the heating pipe is selectively connected to the auxiliary boiler or the diffuser of the thermal storage tub for heating through the medium of a fourth three-way valve.
