喷汽增焓技术在城轨车辆空调供热中的应用分析

摘要

At present, urban rail transit is developing rapidly in China, but the cost of energy consumption is very high in rail vehicle air conditioning. In this paper, the theory of jet pump heating and the technology of enthalpy heating are analyzed and compared, the result verifies that the rail vehicle air conditioning by enthalpy jet technology could replace the electric heating adder.%对普通热泵供热与喷汽增焓技术供热的城市轨道交通车辆空调机组的制热量进行理论分析、比较.理论计算数据证明,我国北京以南地区运行的城市轨道交通车辆空调冬季应用喷汽增焓技术替代电加热器供热是可行的.
