HEAT UTILIZATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a heat utilization system capable of improving a thermal storage efficiency.SOLUTION: This invention comprises: a heat collection panel 11 for collecting solar heat; a solar heat storage tank 12 for storing solar heat; a first circulation mechanism 13 for transmitting solar heat from the heat collection panel 11 to the solar heat storage tank 12; a power generating unit 21 for generating power under application of fuel and generating waste-heat; a waste-heat storage tank 22 for storing waste-heat; a second circulation mechanism 23 for transmitting the waste-heat from the power generating unit 21 to the waste-heat storage tank 22; a relative circulation mechanism 30 for transmitting heat from a high temperature side to a low temperature side of thermal media of the solar heat storage tank 12 and thermal media of the waste-heat storage tank 22; and a control device 70 for operating the relative circulation mechanism 30 when the first circulation mechanism 13 is operated and a temperature of the thermal media stored in the waste-heat storage tank 22 is lower than a temperature of the thermal media stored in the solar heat storage tank 12 and decreasing a temperature of the thermal media stored in the solar heat storage tank 12.SELECTED DRAWING: Figure 1
