WSHP System Control and Optimization Part 4: Why Waterside Economizing Might Not Improve Efficiency

Engineers seeking to meet the waterside economizing requirement of ASHRAE 90.1 - 2013 do not necessarily have to specify multi-zone commercial water source heap pumps with integral economizers. In fact, doing so may undermine efficiency.

How To Size A Waterside Economizer Part 5: Why Plate & Frame Heat Exchangers Are Preferred

Waterside economizing typically involves the transfer of BTUs from an open loop cooling tower system to a closed loop chilled water system. Since these two hydronic systems must remain separate so we do not foul the chilled water systems, a heat exchanger is required to prevent mixing of the fluids, but what type of heat exchanger should you choose?
