摘　　要：本文分析了引起蒸发器各路盘管不均匀供液的两方面原因,以两相流理论为依据,提出了一种新型的压降型分液器,并对其分配性能开展实验研究。借用统计学中标准误差的概念整理实验结果,发现入口干度是影响分配性能的主要因素,而入口压力影响较小。In this paper the two reason which result in the differential refrigerant supply to evaporator is analyzed. A new type of liquid-distributor is proposed based on the theory of two-phase flow. The study to the performance of distribution is developed. The experiment result reflects that the inlet vapor quality is the primary factor and the inlet pressure is the minor factor which influences the distribution performance of liquid-distributor.
