Beijing Fangshan Institution And School Heating System

The clean energy transformation project of coal-fired boiler in Fangshan District Education System covers 19 schools including Qinglonghu Primary School, Jiyang Primary School, Gongyizhuang Primary School, Caozhang Primary School and Zhaogezhuang Primary School, with a total area of about 40000 square meters. The system uses Kcalin air source heat pump to replace the traditional coal-fired boiler for heating. The heating effect is continuous and stable, safe and reliable, clean and environmentally friendly, creating a warm and comfortable learning environment for children, which is highly recognized by teachers and students of the school. The project was completed and officially put into use in October 2015.
