拉萨市供暖技术的适宜性分析

Suitability analysis for Lhasa heating techniques

充分考虑拉萨市太阳能资源丰富、矿物能源匮乏和生态环境脆弱等特点,通过对气候条件、能源供应情况、建筑特征和热负荷特性等要素的分析,对拉萨市利用天然气、电力等常规能源的各种供暖方案进行了分析对比,结果表明:城市集中供暖和大规模的区域集中供暖不适宜在拉萨采用,而应采用分散式或楼栋式供暖系统形式。合理的供暖方案既能满足人们对室内热舒适环境的需求,又有利于降低能源的消耗和污染物的排放,保护拉萨的生态环境。

Considering the characteristics of abundant solar energy resources, scarce mineral energy and fragile ecological environment in Lhasa, by analysing the climate conditions, energy supply situation, building characteristics and thermal load characteristics, compares various heating schemes of utilizing conventional energy sources such as natural gas and electricity. The results show that the urban central heating and large-scale district heating are not suitable in Lhasa and that the decentralized heating system should be adopted for satisfying the demand of indoor thermal comfort, reducing energy consumption and pollutant emissions and protecting local ecological environment.
