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?

How To Size A Waterside Economizer Part 1: How ASHRAE 90.1 Updates Have (Or WILL) Change Chilled Water Design

Has your state adopted ASHRAE 90.1-2010 or beyond into its commercial building code? If so, then it is highly likely that you should be incorporating either waterside or airside economizing into your cooling design. The Standard has effectively made air or waterside economizing a requirement in virtually every…
