降低采暖能耗是寒冷地区建筑节能的重要课题。要降低采暖能耗,一是提高锅炉和管网热效率,减少管道热损失;二是在建筑设计时,采取节能措施,即设计节能型建筑,这是一种长期受益的治本方法。采用小型混凝土空心砌块可提高外围护结构保温性能,它的技术经济指标可与普通砖混建筑相比较,已被世界上100多个国家广泛采用。与其他国家相比较,我国的小型混凝土空心砌块生产量很少。
Reducing heating energy consumption is an important issue for building energy conservation in cold regions. To reduce heating energy consumption, the first is to increase the thermal efficiency of boilers and pipe networks and reduce the heat loss from pipelines. Second, when building design, energy conservation measures should be taken to design energy-efficient buildings. This is a permanent cure for long-term benefits. The use of small concrete hollow blocks can improve the thermal insulation performance of the external protective structure. Its technical and economic indicators can be compared with common brick and concrete buildings, and has been widely used in more than 100 countries in the world. Compared with other countries, the production of small concrete hollow blocks in China is very small.
