Modeling and OPtimization of a Refrigeration System for Metro Train Air_conditioning
摘要
Abstract
Though metro in China today is booming, the typical refrigeration system for metro train air_conditioning is at quite lower ener_gy efficiency level (COP =2.2 _2.3) in comparison with the residential systems under the same operating conditions.A refrigeration system model was developed to predict the metro train air_conditioning system performance.The predictions agreed well with the experi_mental data.Based on comprehensive modeling and analysis, the refrigerant circuitries of condenser and evaporator were optimized and smaller capacity compressor of higher COP was adopted.Consequently, the optimized system COP increased 21.7﹪ at almost the same cooling capacity and cost.At last, the refrigerant R407C was replaced by R410A and the system were accordingly redesigned, which brought additional 11.3﹪ COP increase and achieved 3.The present method and results could be valuable for designing high performance air_conditioning system of the metro train.关键词
