Full Description

This product contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.

This session investigates the energy efficiency of several alternative Low Global Warming Potential refrigerant blends. The presentations address the thermodynamics of the blends, including the associated temperature glide in the heat exchangers. They also focus on the types of application whether the blend is intended for drop-in or near drop-in service or whether intensive changes are required to capture the best performance. Comparisons from the recent AHRI alternative refrigerants program are also presented to show the most recent developments and state of the art.
