저온 공조용 축열 시스템에서 열 저장 특성에 관한 연구

초록

This research, which accomplish an analytical and experimental study regarding the methods improve heat stores of TESS (Thermal Energy Storage System). In this paper, by the enthalpy method, confirmed an analytic result of smooth tube (Kim, 1991) and experimental result and fin attachment it led and effectiveness of heat exchangers that expand heat exchange surfaces with the solidification rate, the energy storage and heat transfer coefficient confirmed. With over the each condition that had become non-dimensional factors, it confirmed heat transfer characteristics as the condition of Ste and Bi.
