A few circumstances in a data center make it ripe for a CHP design to boost efficiency. Let’s get into the options within both relevant chiller types, why payback may be shorter than expected, and the assorted potential benefits from lower costs to higher reliability. Some tips from an array of manufacturers’ reps round out this useful investigation.
This month’s B2B will focus on an existing datacom room located within a 200,000-sq-ft financial business office building. The existing datacom room is being expanded from 10,000 sq ft to 20,000 sq ft.
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.
When the City of Tallahassee and Leon County collaborated on a consolidated public safety complex to deal with local emergencies, the stakes were high and the need for robust yet adaptable HVAC was, too. Another collaboration within the design — chilled beams and pump technology — represented a key component of the mechanical system as it stands ready for severe swings in occupancy and weather alike.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
