While CHP is good, CCHP can be even better for your facility and its locale. The author surveys the potential benefits, building code input, and electrical considerations. After a couple of case studies, she then reviews considerable engineering re-sources the DOE provides for those contemplating a forward-looking but proven design.
More specifically, has natural gas been overlooked? Let’s take a look at some previous habits and code language, current needs, and the advantages that a CHP system can provide for those exceedingly regulated of all environments: hospitals.
Emergency generators are required in many applications where facility operations are to continue to perform even upon a failure of the electric grid. The best resources for quantifying the emergency generation classifications, capacities, installation, maintenance, and operational testing requirements are the building codes and federal regulations.
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.
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.
While mechanical energy codes may lag relative to the efficiency targets of some other codes , the expansion of VRF into a wider range of equipment makes it easier than ever to exceed expectations. Perhaps more importantly, its incorporation into heat pumps, dehu-midifiers, compressors, and more represents more flexibility in delivering an effective retrofit without a total system overhaul.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop.
