The use of refrigerants with low global warming potential (GWP) may require changes in heat exchanger designs which include internal enhancements or reduced internal volume. This seminar presents information on modeling and test results with low GWP refrigerants that will enable equipment designers to plan for any impending changes that will be required to accommodate low GWP refrigerants.
Understanding the acoustics characteristics of HVAC equipment and designing in the proper sound levels is important to building occupants’ comfort. This session covers the sound characteristics of various chillers, including fixed and more efficient variable speed designs. An in-depth discussion is presented for a new AHRI standard 1280P, which provides the sound power rating method for water-cooled chillers. The general operation principles for active chilled beams and the primary sound generation mechanism are introduced. An overview of how the acoustic performance is measured and cataloged is provided. Selection and performance guidelines are also presented.
