Dabaodang Town is located in the southwest of Shenmu City, Shaanxi Province. There are huge treasures underground, containing coal and natural gas resources. Under the strategic plan of the country's western development. Shenhua, Shaanxi Coal Chemical, Yanchang and other coal chemical projects with a scale of 100 billion are under construction here, becoming the world's largest coal chemical base. Including Shaanxi Coal Group's Yulin Chemical Coal Separated Utilization of New Chemical Materials Demonstration Project. Linde Engineering provided the design, manufacture, supply and service of three ultra-large air separation plants for the project. After the device is completed, it will provide high-pressure oxygen for the coal-to-glycol gas chemical section, as well as low-pressure oxygen and medium/low-pressure nitrogen required by other sections, and at the same time supplement instrument air, factory air and other products for the public engineering system of the plant.

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.
