The proportion of renewable energy consumption in the building sector accounts for more than 15% of building energy consumption. Green buildings and low-carbon buildings have become a major trend in building development.
但目前，小型单体建筑仍然普遍采用以燃煤、秸杆为燃料的小型家用锅炉，其缺点是仍然使用不可再生能源，并且造成环境污染，同时热效率低，自动化程度不高。为了解决上述问题，现有采用太阳能集热系统实现可再生能源的利用，但是其受气候和地域的影响较大，不能完全满足供热需求。 But at present, small single buildings still generally use small domestic boilers that use coal and straw as fuel.

In order to solve the above problems, the existing solar heat collection system is used to realize the utilization of renewable energy, but it is greatly affected by climate and region, and cannot fully meet the heating demand.
