Technical and economical analysis of chilled water direct supply system in Hongqiao Transport Hub Terminal 2

With the chilled water system in the project, analyses and compares the initial investment and operating energy consumption between the chilled water direct supply system and the indirect system with plate heat exchanger at the user side. Calculating results show that the initial investment of the former can be about 13.95 million RMB less and the electric energy consumption can be about 624 MW·h less than that of the latter, suggesting that the chilled water direct supply system is economically reasonable to some extent.
