Warm discharge plumes sweeping back into air-cooled condensers is nobody’s idea of an ideal performance environment. This CFD study shows how wind speed, wind direction, spacing between chillers, and separation from adjacent buildings all factor into the conversation about the best defense against unwanted hot air.
As one of the largest commercial real estate firms in the southeastern United States, Childress Klein oversees and services nearly 40 million sq ft of office, industrial, retail and residential properties.
Trends don’t always follow the expected path (or timeline), but the basics remain the basics and increased cabinet density remains inevitable. Let’s revisit the progress of liquid in data center strategy and the tenets of a future-proof(ish) hybrid design for today.
Thanks to a recent remodeling, patrons seated indoors experience the ambience of dining outdoors at O’Toole’s Irish American Grill & Bar. However, there are no mosquitoes, flies, or vehicle emission odors, and the temperature is always a comfortable 74°F.
Why do ground loops in moist soils sometimes perform better than expected? What ground loop design tactics can address building system imbalance? Engineers need to take more responsibility for their full GSHP designs, and these questions are a good place to start.
With a little guidance on ground-source heat pump design temperatures and a few rules of thumb for ground loop flow rates, most engineers are pretty comfortable designing the building side of a ground-source heat pump (GSHP) system.
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.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
