THERMAL ENERGY STORAGE FACILITY HAVING FUNCTIONS OF HEAT STORAGE AND HEAT RELEASE
Abstract:
A thermal energy storage facility for use in heat storage and heat release comprises a heat storage/release mechanism constituted by multiple heat storage/heat exchange units stacked up, each unit at least comprises a heat storage board having parallel grooves for loading phase-change material (PCM) therein and a heat exchange plate having micro-channel groups for heat transfer fluid (HTF) flowed through to exchange heat with the PCM; particularly two or more the thermal energy storage facilities can be worked together by combination in series or/and in parallel to input of thermal energy, absorption of thermal energy and both simultaneously from the PCM, and the thermal energy storage facility capably operating at a heat storage temperature higher than 1200° C. is suited for use in solar thermal power generation system to improve overall efficiency of solar thermal power to reach 35-40%.
