액인젝션을 적용한 열펌프의 운전변수에 따른 성능 특성에 관한 해석적 연구

Air-source heat pump shows the performance degradation at severe ambient temperatures. Many researches on injection technique have been conducted in recent years. In this study, a simulation program for a heat pump cycle with liquid injection technique was developed. The simulation model was developed based on the mass and energy balances, and verified by the experiments at various operating conditions. This study discussed cycle performance characteristics with the operating parameters by the simulation program.
