A Dallas-Fort Worth hospital's new boiler system project uses the principle of lowering the heating-water temperatures to allow for innovative ways to recover heat, according to a case study on the Consulting-Specifying Engineer website.
The use of heat-recovery chillers was evaluated early in the project's design process. Pricing estimates were made comparing a low-temperature hot-water system with a typical heating-water system.
It was decided that neither the cooling towers nor heating-water boilers would be downsized to take advantage of the heat recovery, according to the article.
Instead, the building would be able to function without any issues if the heat-recovery system was disabled.
