Northwell Health is spending $4.7 million to place four efficient cooling systems on Huntington Hospital’s roof above the north wing of the facility.
New Hyde Park-based Northwell said the energy-efficient chillers will save the health system about $240,000 in energy bills annually — a 10 percent overall reduction.
“The fan motors and compressors in the new chillers have the ability to adjust their production specific to actual demand," said Randy Howard, vice president of operations at Huntington Hospital. "Older systems would be running at 100 percent capacity independent of cooling demands.”
Along with the energy savings, Huntington Hospital will earn about $200,000 in energy rebates from PSEG, Northwell said.
The Carrier chillers replace a traditional water-cooled system.
Separately, Huntington Hospital is working with the Town of Huntington, the local senior center, the water treatment plant and the Huntington YMCA to create a power microgrid. Huntington Hospital said the microgrid gives it an extra level of security against losing power. The hospital also has a generator that could keep it on line for up to 96 hours.
Northwell Health is the state’s largest health care provider and its largest private employer, with 66,000 employees, 23 hospitals, more than 650 outpatient facilities and nearly 15,000 affiliated physicians.
