摘　　要：检查库内的热源特性情况关系到动车检查库内通风系统的设计和热环境的改善。对夏热冬冷地区和夏热冬暖地区五个动车检查库开展了库内热源得热测试与调研,结果表明:实地测试到库内总得热的最大值达69.5W/m^(2)。列车空调系统散热和太阳辐射是库内得热的主要来源,列车空调系统散热单位面积散热强度可达28.8~31W/m^(2),太阳辐射单位面积散热强度可达24.2~35.2W/m^(2)。设计工况下库内白天得热在78.4~96.4W/m^(2),在夏热冬冷和夏热冬暖地区间差异不大。The characteristics of heat source in the EMU inspection workshop are related to the design of ventilation system and the improvement of thermal environment.In this paper,five EMU inspection workshops were tested and investigated in hot summer and cold winter areas and hot summer and warm winter areas.The results show that the maximum value of total heat gain is 69.5W/m^(2).Heat dissipation of train air conditioning system and solar radiation are the main source of heat gain in the EMU inspection workshop.The heat dissipation intensity per unit area of train air conditioning system can reach 28.8~31.0 W/m^(2),and the heat dissipation intensity per unit area of solar radiation can reach 24.2~35.2 W/m^(2).Under the design condition,the daytime heat gain is in the range of 78.4~96.4 W/m^(2).There is little difference in heat gain in the warehouse between hot summer and cold winter and hot summer and warm winter.
