Massachusetts Eye and Ear Infirmary Home / Markets & Projects / Massachusetts Eye and Ear Infirmary Boston, MA Equipment: Buffalo Air Handling supplied two (2) custom indoor air handling units configured with a 40,000 cfm unit stacked on a 23,000 cfm unit. The units are 2″ double wall construction with supply fans, heating and cooling coils, pre and final filters, dampers, humidifiers, and internal piping. Consulting Engineers: Engineered Solutions, Inc. Mechanical Contractor: TG Gallagher Massachusetts Eye and Ear Infirmary is an independent hospital, specializing in the care and treatment of, patients with disorders of the eyes, ears, nose, throat, head and neck. Internationally acclaimed since its founding in 1824 by two young eye surgeons named John Jeffries and Edward Reynolds as a charitable eye clinic, Mass. Eye and Ear offers high quality and specialty care ranging from the routine to the very complex. The facility for which the two air handling units were supplied was built in the mid-1970’s and is one of multiple facilities throughout Greater Boston and Providence. The challenge for this AHU-29 & AHU-30 Replacement Project was how to increase the capacity with no additional floor space, limited access to the area, and structural cross beams in the way. The solution was to stack one unit on top of the other, despite having different air flow capacities, utilize knockdown construction for the top unit and design a way to encapsulate the cross beams. Adding to the challenge was the requirement that the units be designed to survive a seismic event and operate afterwards. The lower unit (AHU-30) is 23,000 cfm and the top unit (AHU-29) is 40,000 cfm. AHU-30 was oversized to accommodate stacking AHU-29, so both had a foot print of 20′-6″L x 19′-0″W. AHU-30 is 5′-10″H while AHU-29 is 10′-?”H. Despite the lower height, the width of AHU-30 necessitated that the unit be split both perpendicular and parallel to airflow, resulting in 20 sections being shipped. Once AHU-30 was reassembled in-place, AHU-29 shipped. That unit was built at the factory, then disassembled and palletized for shipment. A Buffalo Air Handling service technician supervised the reassembly of the top unit and worked with the installing contractor to coordinate the accommodation of the cross beams.
