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.

The seminar addresses low-GWP alternative refrigerants and their applications. As regulations and legislation become increasingly more widespread and restrictive, the HVACR industry will need to identify viable alternatives for existing refrigerant solutions. This environmentally-driven change is different than past ones since additional constraints are being placed on refrigerants in essence reducing the number of viable single-component solutions. The seminar highlights five papers appearing in ASHRAEs Science and Technology for the Built Environment November 2016 edition (one dedicated specifically to low-GWP refrigerants.) The presentations focus on low-GWP halocarbon refrigerants containing unsaturated carbon bonds during boiling heat transfer and in system applications.
