Seminar 26 -- Load Calculation Considerations for Radiant Systems

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

Radiant systems have different cooling load characteristics than all-air systems, but most load calculations methodologies are designed for all-air systems. This session discusses elements considered in radiant system load calculations, the problems with designing radiant systems using all-air system methods, review results from two recent radiant system research projects and present a design tool for radiant system load calculations.
