운전방식에 따른 히트펌프-축열시스템의 성능 비교

This study describes the performance simulation results of thermal storage system with heat-pump according to control method. Two control methods of heat-pump priority and storage priority are adopted for simulation. TRNSYS is used to obtain the building cooling load. Mathematical models such as heat pump, thermal storage tank are developed and system performance are carried out under the condition of cooling load by TRNSYS. Power consumption and operation cost are evaluated for each strategy.
