Celebrates Diamond Anniversary of Centrifugal Chillers PHILADELPHIA, Jan. 28 -- Celebrating the 75th anniversary of Dr. Willis Carrier's first "centrifugal refrigerating machine" at the IAHR Expo here, Carrier introduced the second phase of its Evergreen centrifugal chillers, the industry's first built from the ground up to use non-ozone-depleting, chlorine-free refrigerant.
Carrier's line of Evergreen centrifugal chillers, with capacities betwen 350-800 tons, will be expanded in 1997 to a range of 200-1,500 tons.
"Eighty percent of all U.S. chiller installations fall into the 200-1,500 ton capacity range," said Roger Morey, vice president and general manager of Carrier's Commercial Applied Equipment and Services group. "Evergreen chillers enable building owners to use environmentally responsible, non-restricted refrigerant without compromising on energy efficiency or safety."
With operating efficiencies approaching .50 kW/ton at full load ARI* 550-92 conditions, Evergreen chillers provide the highest operating efficiency to date of any chiller using chlorine-free refrigerant, while offering the best cost/performance value among such chillers.
Today's Evergreen chillers are well-suited for commercial and industrial buildings, including facilities such as hospitals and information management centers that have intensive and constant energy needs, allowing building owners to realize lower operating costs
Customers benefit from more than 375 different compressor-heat exchanger combinations, which optimize performance for specific applications. As a result, chillers can be customized to specific capacities and efficiencies required by building owners.
Three additional technological advances increase the efficiency of Evergreen chillers:
Maintenance and service costs are minimized by the chillers' easily accessible components. Optional refrigerant isolation valves allow refrigerant to be stored in one of the heat exchangers, providing a built-in containment system so the unit can be serviced without removing the refrigerant charge.
