PURPOSE:To improve the efficiency of heat exchange, and prevent the heat transfer medium from decomposition and denaturing caused by the localized over-heating of said heat transfer medium by a method wherein a heat resistant heat transfer medium oil in the No.1 circulating system is heated by a boiler, then the heat transfer medium in the generator of the No.2 circulating system is indirectly heated by the heat radiation of the heat transfer medium in a radiator. CONSTITUTION:A heat transfer medium oil 12 heated by a burner 10 in a boiler 11 is raised in an oil sending pipe 14 in high temperature liquid condition, then flowed into a radiator 13 located at a position higher than a boiler 11. The high temperature heat transfer medium oil 12 flowed into the radiator 13 is flowed down while radiating the heat to a heat transfer medium 18 in a generator 17, then naturally dropped down in an oil return pipe 15 reducing to low temperature, finally returned to said boiler 11. Meanwhile, the liquid phase heat transfer medium 18 in said generator 17 is heated by the heat which is transferred with said heat transfer medium oil 12, changed to the saturated vapor, then raised up in a steam pipe 20, flowed into a condenser 19 located at the position higher than said generator 17. The vapor phase heat transfer medium supplied into said condenser 19 is condensed and radiates the condensation heat. The liberated condensation heat is used for space heating. |
