MEASUREMENT OF TUBE BUNDLE COOLERS UNDER WORKING CONDITIONS

摘要

This paper deals with the experiments on the two tube bundle coolers. The results are used for verification of theoretical relations for the heat transfer coefficient and pressure losses, and for the extending their limits of applicability. The coolers with the smooth and finned tubes, with clean and dirty surface are compared. The ability of the finned tubes for the coolers of the lubricated compressors were investigated.
