浅析地下空间节能关键技术

地下空间的开发利用,可在有限的城市土地资源上拓展生存空间,增加城市空间容量.地下空间建筑独特的环境特点及热工性能决定了地下建筑主要能耗为空调系统、照明系统、机械通风以及电梯的电能耗.因此,节能关键技术包括地源热泵、光导照明、LED节能照明,以及自然通风等高效节能系统.随着我国许多大城市进入大规模开发规划地下空间的历史时期,地下空间领域节能关键技术的应用将具有重要的战略意义及巨大的社会、经济价值.

Crucial Technologies of Energy-conservation for the Underground Space

The development and utilization of underground space can add spatial capacity and urban land resources in the limited living space.The unique environment characteristics and the thermal performance of underground space decide the main energy consumption of underground architecture,including air conditioning system,lighting system,mechanical ventilation and elevator electrical energy consumption.The key technologies of energy-conservation contains of the ground source heat pump,light-pipe lighting,LED lighting and natural ventilation high efficiency energy saving system.With the large-scale development planning period of underground space in many metropolitans of China,the application of the key technologies of energy-conservation will be of great significance and huge economic value to the society.
