A THERMAL STORAGE TANK CAPABLE OF MEASURING THERMAL STORAGE VOLUME AND A METHOD FOR MEASURING THERMAL STORAGE VOLUME USING THE SAME

摘要

According to one embodiment of the present invention, since the amount of heat storage can be measured using buoyancy when the latent heat storage material which changes phase changes into a solid phase, the heat storage amount can be measured without using a temperature measurement, and thus the accuracy of the heat storage amount measurement is improved. It provides a heat storage tank that can be improved. A latent heat storage type heat storage tank capable of measuring heat storage amount according to an embodiment of the present invention includes: a partition portion coupled to an inner surface of a housing and partitioning an inner space of the housing into a plurality of heat storage spaces; A latent heat storage material which is filled in the heat storage space and whose buoyancy is varied by phase change; A contact portion coupled to the upper surface of the plurality of surfaces forming the heat storage space, spaced apart from the top surface of the heat storage space, and in contact with the latent heat storage material; A sensor unit disposed between the upper surface and the contact portion of the heat storage space and detecting a state change between the upper surface and the contact portion of the heat storage space; And a flow tube through which the fluid that exchanges heat with the latent heat storage material flows.
