The assortment of standards, variety of technologies, and evolving weather patterns don’t make it simple. However, humidification and dehumidification strategies that suit the facility’s location and address some spaces’ specialized demands are worth the effort.
A pre-retrofit report card helped this major Chicago health care facility chart a smart course of treatment for its HVAC. After improvements for chillers, cooling towers, refrigerants, pumps, and more, the hospital’s central plant upgrade now looks forward to long-term savings, cleaner operations with streamlined maintenance, and better reliability.
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.
In which CFD modeling lets us compare two possible design configurations for ventilation in a hospital patient room, yielding some similarities and perhaps surprising differences in what each configuration means for pathogen control and occupant comfort.
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.
When a community-based hospital adds a neonatal intensive care unit (NICU) so its most fragile patients can be cared for in-house rather than at a regional center 50 miles away, a family places enormous trust in the hospital’s ability to meet its baby’s health care needs.
Pressure independent control valves proved to be a key in wringing the benefits out of smartly managed chilled water temperature, but that wasn’t all. Airside energy recovery, desiccant dehumidification to eliminate reheat in operating room environments, and upgrading to ECM fan systems have all contributed to this hospital’s fiscal wellness.
From a missing pipe hanger three floors down to steam traps past their prime, these stories show how steam system problems can originate inside the boiler room or far beyond it. Read more in February issue.
