Twenty-five ways to raise your chilled-water temperature differential.

Author(s) : FIORINO D. P.

Summary

The paper recommends practical methods of achieving high chilled-water temperature differentials in variable-flow hydronic cooling systems. After high chilled-water temperature differentials are realized, more British thermal units of cooling will be accomplished per gallon (liter) of chilled-water distributed, and pressure losses and pumping energy will decline considerably. Also, water chiller capacities no longer will be limited by maximum evaporator flow rates and chilled-water storage tanks will store many more ton-hours (megajoules) of cooling. This fundamental approach provides significant, enduring improvements in the performance of variable-flow hydronic cooling systems with great leverage.
