| Abstract: | This study is concerned with a new reverse-cycle hot gas method using phase change thermal energy storage(TES) to eliminate frost in an air-source heat pump(ASHP),which can effectively solve the shortage of defrosting energy.The feasibility of defrosting was investigated through experiments and the modes' performances were compared with a norminal 850 W capacity ASHP system conventional reverse-cycle hot gas defrosting method.The results have indicated that thermal energy storage based reverse-cycle hot gas... |
