摘要 针对寒冷地区地下车库是否需要设置供暖系统的争论，在典型低温气候条件下，对北京市一个无供暖地下车库的温度进行了实测。结果表明，该地下车库绝大部分区域的空气温度高于0 ℃，口部附近空气温度低于0 ℃，但消火栓及消防水管的表面温度仍高于0 ℃；并对地下车库不设供暖系统的节能效益进行了分析，认为在消防系统采取适当防冻措施的前提下，寒冷地区地下车库不设供暖系统是可行的，而且可以产生节能减排效益和经济效益。 关键词 地下车库 无供暖　冬季温度状况 测试 北京市 Thermal conditions test and analysis of an unheated underground garage in Beijing in winter By Li Zhaojian★, Liu Ying, Zhang Xiaohang and Wu Fei Abstract Aimed at the argument over whether underground garages need heating in cold areas, tests the thermal conditions of the garage in typical winter weather conditions. The results show that the air temperatures in most spots of the garage are higher than 0 ℃, the air temperature near the entrance or the exit is lower than 0 ℃, but the surface temperatures of fire hydrant and water pipe for fire fighting are still higher than 0 ℃. Analyses the energy-saving benefit of the measure without heating in the underground garage. Considers that the scheme that the underground garages do not be equipped with heating systems is acceptable in cold regions, on the condition that the suitable measures against freezing are taken to the fire fighting system, and it will produce significant benefits of energy-saving, environment and economy.
