ST. LOUIS — Emerson Climate Technologies announced that two of its engineers, Hung Pham and Autumn Nicholson, will present an educational session reviewing different compressor tests using low global warming potential (GWP) refrigerants available for air conditioning and refrigeration applications at the Air Conditioning, Heating, and Refrigeration Institute’s (AHRI) Low-GWP Alternative Refrigerants Evaluation Program (AREP) Conference.
The presentation will take place on Jan. 16, 2014, in New York, prior to the start of the annual ASHRAE Winter Conference. AREP is an industry-wide cooperative research program that identifies and evaluates promising alternative refrigerants for major product categories, including air conditioners, heat pumps, chillers, ice makers, and refrigeration equipment.
Emerson will share insights on compressor performance evaluation for low-GWP refrigerants with program attendees. For instance, compressor test results for high-glide refrigerants at mid-point relate better to actual system performance when compared to dew point. Also, a compressor test evaluation alone may not be sufficient and should be accompanied by a system evaluation.
Pham, who serves as director of integrated technologies at Emerson Climate Technologies, has more than 35 years of experience with HVACR system technology, including refrigerants, components, and control strategies. He is actively involved with industry technical committees in AHRI, ASHRAE, and the Air Conditioning Contractors of America (ACCA), as well as regulatory organizations such as the U.S. Department of Energy (DOE) and the American Council for an Energy-Efficient Economy (ACEEE).
Nicholson, a senior sales engineer, has been with Emerson Climate Technologies since 2006. She started as a co-op in the refrigeration application engineering and compressor engineering groups, and most recently, her role has been as a sales engineer for refrigeration customers. Her work focuses on compressor and refrigeration system energy and TEWI analysis, with a focus on refrigerant alternatives and/or system architecture.
