It’s not necessarily a plug-and-play situation, but these chillers can play key roles and deliver meaningful savings in several scenarios. Waste heat, CCHP, standalone, and even renewable solar as part of the refrigeration cycle can all provide the setting for absorption success.
These sensitive applications call for looking at several established humidification techniques through a particular lens. The authors not only review the processes involved in various technologies but also some relevant secondary effects, such as a change (or no change) in the air temperature, that could be especially meaningful in a data center.
It’s not a new technology, but it’s more popular than ever. While VRF is providing engineers and building owners with a financial payback, the benefits go beyond energy efficiency.
This month, I want to address an issue which is as old as building systems commissioning itself. It was one of the first challenges commissioning professionals endeavored to resolve in order to more effectively and efficiently facilitate the commissioning process … and yet it still lingers.

School, warehouse, office building … the boiler stories they tell put the focus back on specific circumstances and smart pre-design study to ensure their systems (and budgets) enjoy the best of times for as long as possible.
