摘　　要：高原寒冷地区气候独特,其室内热环境有异于平原寒冷地区。冬季室内热环境质量差,且室内温度非均匀分布缺乏深入的分析和评估。通过现场实验测试了室内外热环境参数,并建立数值模型,结合实测温度校验。在冬季典型气象日,与同处严寒气候区的平原城市北京对比,拉萨室内温度和辐射温度更高,但辐射温度不对称也更加明显。受太阳辐射、散热器和北外窗的强冷辐射影响,人体最大不对称辐射温差可达3.95℃,头部甚至达到8.73℃。由于强太阳辐射和低气温,建筑应尽量避免设置北向外窗,并加强保温。此外,拉萨需要更加适宜的室内热环境设计、评价规范,以改善室内热环境质量。The climate in the cold plateau area is unique,and its indoor thermal environment is different from other cold areas in plain.The indoor thermal environment is poor.In addition,there is a lack of depth research and evaluation of non⁃uniform temperature distribution.The field experiments are carried out for indoor and outdoor thermal environment parameters.The numerical model is built and validated by measured data.On the typical weather day of winter,Lhasa’s indoor temperature and radiation temperature are higher,but the radiant temperature asymmetry is also more obvious when those are compared with Beijing(plain cold area).Due to the strong solar radiation,radiator,and cold radiation of the north outer window,the maximum radiant temperature asymmetry of humans can be reached 3.95℃,and even reached 8.73℃for the head.Due to strong solar radiation and low ambient temperature,the building should avoid setting north windows as far as possible and strengthen thermal insulation.In addition,Lhasa urgently needs suitable indoor thermal environment design and evaluation specifications to improve the indoor thermal environment quality.
