Primary/Secondary vs. Primary-Only Pumping

April 2011
Heating/Piping/Air Conditioning Engineering;Apr2011, Vol. 83 Issue 4, p34
The article discusses a study on the impact of two pumping approaches for water distribution in central chiller plants on the total plant kilowatt demand including the primary/secondary (P/S) and primary-only (P-only) pumping. It mentions the use of chiller-plant model in the study which adheres the fundamental principal of the law of thermodynamics. Moreover, several charts and graphs are presented depicting the performance of the two pumping approaches.
