2013 RESEARCH YEARBOOK
Dr. Margaret Mathison assistant professor, mechanical engineering What is she working on? One of the greatest challenges facing the heating, ventilating, airconditioning and refrigeration industry is transitioning to new working fluids with lower global warming potential (GWP) than current refrigerants. To that end, Mathison worked with a team of senior design students to rebuild a room air conditioner to run with a newly developed, low-GWP refrigerant alternative in a project sponsored by Whirlpool Corporation. The team’s working model hit its target cooling capacity.
What’s the impact? Mathison’s research will help ensure the HVAC&R industry is prepared for the future and ready to act as responsible stewards of environmental resources by minimizing energy consumption and the emission of potentially hazardous chemicals.

What about the energy consumption impact of HVAC&R equipment? Mathison is working on that, too, designing and building a load stand to improve the efficiency of the main power-consuming component in any air-conditioning or refrigeration cycle: the compressors. The load stand will be capable of supplying liquid-vapor mixtures to the compressor at two intermediate pressures, a design unique to Marquette.
