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.
Atypical load profile for a hospital might show heat energy increases in the winter, with electric demand peaks in the summer as seen in Figures 1 and 2.
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.
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.
In today’s complex web of regulations, equipment and fuel options, and traditional threats to facility operations, it only makes sense to get up to speed on CHP.
Whether low-cost adjustments, targeted replacements, or a substantial retrofit when large equipment has run its course, you almost always have a good move available to conserve energy and expense.
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.
Wide temperature swings, submetering deficiencies, bloated carbon footprint … these are but three of the problems tackled in two contrasting projects in the Northwest.
How is variable refrigerant flow (VRF) working for you? We asked a number of people that question and summarized the findings from two typical facilities here.
