我国长江下游地区冬季湿冷,夏季酷热,一般住宅不设集中采暖装置,致使冬夏季室内热环境条件极差。我们从改善围护结构热工性能及合理设计着手,利用被动太阳能技术实现低水平室内热舒适环境条件。试点建筑经冬夏季实测,证明达到了预期目标,并验证了设计方法的可信性。 In the lower reaches of the Yangtze River in China, it is cold in winter and hot in summer. There are no centralized heating devices in residential buildings, resulting in extremely poor indoor thermal environment in winter and summer. We started from the improvement of the thermal performance of the envelope structure and the rational design, using passive solar technology to achieve a low level of indoor thermal comfort environmental conditions. The actual construction of the pilot buildings in winter and summer proved that they had achieved the expected goals and verified the credibility of the design methods.
