Abstract:
Concentrated cooling technique is adopted in Guangzhou Subway Line 2 and Rail Transit Line 3 projects, where the chilled water pipe is 15 000m long. Foamglas foam glass heat insulating material is used to solve the technical difficulties in long-distance and high-efficiency chilled water supply. Characteristics of such material, such as waterproof, fireproof and environmental protection, etc., and technical problems in construction are introduced.
