Description
Recommends practical methods for achieving high chilled water temperature differentials (Delta Ts) of 15degF (8.3decC) or greater in variable flow hydronic cooling systems. States this allows more Btus (J/s) of cooling to be accomplished per gallon of chilled water distributed. Pressure losses and pumping energy will decline considerably in existing hydronic cooling systems and smaller pumps and piping may be installed in new hydronic cooling systems. Also water chiller capacities will no longer be limited by maximum evaporator flow rate and chilled water storage tanks will store many more ton-hours (MJ) of cooling. States that this fundamental approach provides significant and enduring improvements in the performance of variable-flow hydronic cooling systems.
