PARAMETRIC STUDY ON THE SIZE OF SHORT-TERM STORAGE TANK FOR A SEASONAL BOREHOLE THERMAL ENERGY STORAGE

抄録

This paper presents parametric study on the size of short-term storage tank (STST) for heat-charging a seasonal borehole thermal energy storage (BTES) with solar flat-plate collector (FPC).The BTES systems with the various size of STSTs and the various outlet set-point temperature were investigated using TRNSYS simulation. As a result, the system with the STST of 50m3 shows the best heat-charging performance, though the system with the STST of 80m3 shows the best solar collecting performance.
