Abstract:

 Based on the environmental characteristics of urban rail transit, analyses the differences of air conditioning system application between rail transit and civil buildings. Analyses the characteristics of centrifugal and screw compressors and the advantages and disadvantages of variable-speed applications. Presents the different effects of water chiller operating conditions on centrifugal and screw compressors. Based on the system application of chiller plants, studies the applicability of the variable-speed centrifugal and screw water chillers, and proposes corresponding optimal strategies.

Keywords:railtransit,variable-speedwaterchiller,centrifugalcompressor,screwcompressor,applicability
