BRIEF HISTORY

The Wayne K. and Lyla L. Masur HVAC Laboratory was inaugurated in February 1995 in a ceremony attended by dignitaries from the University of Florida and the local, regional, and national American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) community. The Laboratory was founded by Dr. S.A. Sherif, Professor of Mechanical and Aerospace Engineering, employing a significant cash donation from the Masur family. Wayne Masur is a successful alumnus of the Mechanical Engineering Department at UF. The Laboratory serves both an instructional and a research mission. Among its research capabilities is a unique experimental facility designed to study frost and ice formation on industrial freezer coils under ice foggy conditions. The Laboratory also includes an air-conditioning demonstration facility, a cooling tower simulator, an air-water heat pump system, and a chilled-water system with an artificial load simulator. Currently, there is an experimental effort to develop deployable heat pump units employing rotary vane expanders for the U.S. Air Force. Hundreds of students have taken part in different instructional and research activities in the Laboratory since its creation in 1995. The Laboratory is housed in Room 110 of the Mechanical and Aerospace Engineering Building B on North-South Drive. For laboratory tours contact Dr. Sherif at (352) 392-7821.
