NATURAL CIRCULATION TYPE SOLAR WATER HEATER WITH INTERNAL CYLINDRICAL HEAT EXCHANGER AND A METHOD OF CONTROLLING THE AUXILIARY HEAT SOURCE BY USING THE SAME

摘要

The present invention relates to a natural circulation type solar energy hot water tank device and an auxiliary heat source control method. More specifically, a heat collecting module unit for absorbing solar radiant energy, including a solar module; A heat storage hot water storage unit for storing the collected heat; A heat storage heat exchanger that is fixedly located inside the heat storage water tank; A water inflow pipe which is a passage through which water flows between the heat storage tank and the heat storage heat exchanger; A hot water outlet pipe which is a passage through which hot water flows to one side of the heat storage water tank; A heat medium raising pipe which is a passage where the heat medium rises from the heat collecting module part to the heat storage heat exchange part; And a heat medium descending pipe which is a passage through which the heat medium descends from the heat storage heat exchange part to the heat collecting module part, wherein the heat storage heat exchange part has an internal cylindrical heat exchanger characterized in that both ends are formed in a cylindrical shape with an open structure inside. A natural circulation type solar energy hot water tank device and a method for controlling an auxiliary heat source in a solar energy hot water tank device.
