PURPOSE: An overheating prevention device of a solar energy heater is provided to minimize costs for installation or maintenance based on principles of an absorption cooler. CONSTITUTION: An overheating prevention device of a solar energy heater comprises a bypass tube(35), heat exchangers(33,34), a controller(40), and an adsorption cooler(50). The bypass tube is installed in thermal medium conduits(31,32) between a collector(25) and a thermal storage tank(22). The bypass tube carries a three-way valve(36) controlling the flow path. The heat exchanger is installed on the bypass tube and one side of the thermal medium conduit. The controller detects the temperature change on the thermal medium conduit and opens and closes the flow path of the bypass tube. |
