摘　　要：通过稳态和动态传热计算方法分析了深圳地区某大型冷库下部地下车库结露风险。通过计算发现,即使冷库地面采取了足够的保温措施,仍会出现冷库地下车库顶棚表面温度低于露点温度的情况。可采取进一步提高地面保温性能或对车库地下室局部空间进行加热的措施消除顶棚局部结露现象。The condensation risk of the underground garage of a large cold storage in Shenzhen is analyzed by steady-state and dynamic heat transfer method.Through calculation,it is found that the surface temperature of the ceiling of the underground garage of the cold storage is still lower than the dew point temperature even if sufficient thermal insulation measures are taken on the ground of the cold storage.To eliminate local condensation on the ceiling,measures can be taken to further improve the thermal insulation performance of the ground or to heat the local space of the garage basement.
