Shengshi Primary School is located in Shiranfang Village, Tucheng Township, Wafangdian City. The original heating facilities are ordinary wall-mounted electric heaters. For a long time, due to the poor thermal insulation performance of the building walls, the school’s winter indoor heating temperature has been below 18℃, and only 12～13℃ in cold weather, which has brought great inconvenience to the work, study and life of teachers and students. And there is a great potential safety hazard in electricity use. After understanding the relevant situation, Bingshan Air Conditioning, after communicating and coordinating with the two-level municipal education authorities and school leaders, decided to assist in the reconstruction of the winter heating facilities of Shengshi Primary School to completely improve the indoor heating effect. After the improvement, it is estimated that the design temperature of indoor heating in winter can reach 20-22℃, which will create a good environment for teachers and students of the school to survive the winter warmly and safely. The assistance program has been highly recognized by the education department and the school.
