가변속 멀티형 열펌프의 실내기간 입구공기 온도차에 따른 정상상태 성능 특성

The major difference between multi heat pumps has advantages over conventional heat pumps in energy conservation and comfortablty. For multi heat pumps, it is essential to have precise control of cooling capacity for each indoor unit having different cooling loads. Based on the experiments with various test conditions, it was found that an indoor unit affected another by refrigerant mass flow rates, evaporating pressures and cooling capacities when temperature differences of inlet air between two indoor units were varied.
