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.
In general, we’ve made so many existing platforms “smart” in other industries (e.g., computers, phones, cars, and household appliances), but we’ve neglected the very thing that powers all the rest — electricity.
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.
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.
This month, a consultant and NFPA committee chairman looks at the major items involved in a hospital’s life safety design. Like the fire risks themselves, the assorted relevant codes are evolving with regard to specifics like smoke dampers. HVAC wall penetrations, alarm zoning, and response plans are just three other aspects to consider in this demanding design environment.
We’ve made some progress, but the fight against hospital-acquired infection (HAI) remains long and uphill. Here, we look at various risks and strategies, putting some thoughts on a wise approach to humidification in the context of the HAI battle.
The Museum of the Bible’s project team was already up against the extremes of Washington weather and the high demands of IAQ for artifact preservation. A system that harnessed adequate cooling, heating, humidification, and ventilation capabilities would still have one more hurdle: a physical footprint of hardly Biblical proportion. Get a first look at this testament to design acumen and true collaboration.
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.
