A Study of Influence of Refrigerant Charge Amount on Evaporative Refrigeration Cycle for Aircraft
摘要
Abstract
A one-dimensional simulation model is established in aircraft evaporative cooling cycle system with the impact of refrigerant charge being exerted on the performance in evaporative cooling cycle system.The paper calculates and analyzes the effects of refrigerant charge on compressor speed,compressor dis-charge characteristics,compressor power consumption,COP(coefficient of performance),and sub-cool-ing degree at different temperatures within the flight envelope.The results show that whether to over-charge or undercharge exerts all an unfavorable influence on the performance of system.At different ambi-ent temperatures,there are differences in the optimal charge amounts corresponding to the minimum com-pressor power consumption and the maximum system COP in increasing with the rise at ambient tempera-ture.In addition,the sub-cooling degree is regarded as a key indicator for evaluating the optimal refriger-ant charge amount,whose stable section is only related to the charge amount within the range.The com-pressor power consumption and the system COP under different working conditions are good in perform-ance.The research results provide a basis for determining the optimal refrigerant charge flow in the air-craft evaporative refrigeration cycle system.关键词
