Ammonia and industrial refrigeration proposals were both considered for the school’s new $7 million facility. Many factors came into play—the ability of the HVAC engineers to reclaim the 105-degree Fahrenheit waste heat; the capacity to use the equipment as a source of air conditioning-chilled glycol when the ice allowed for multipurpose-use of the facility; the fact that the mechanical room contained a boiler that could easily coexist with the ice³ Cubes, as their refrigerant charge was less than 20 pounds under the threshold for requiring specialty construction and divided rooms; and finally, cost. When analyzed, the ice³ Cubes were less expensive than an industrial plant in this application. The customer opted for a ice³ Cubedecoupler, stainless snowmelt coil and a warm floor, allowing the option of potential, year-round operation.
