Evaluation of HFC-245ca for commercial use in low pressure chillers. Final report, Volume II: Chiller test data

摘要

The chiller was a 200 nominal ton three stage direct drive centrifugal chiller with two economizers. Three sets of impellers, three refrigerants, and two oils were tested in the chiller. Runs 1 through 6 were to optimize the refrigerant charge using CFC-11. This was determined to be 360 lbm (163.3 Kg) and this value was used for all three refrigerants. The data which follow are divided into Large Impeller, Medium Impeller, and Small Impeller sets further subdivided by Imperial and Metric presentation.
