Seminar 55 -- Next Generation Equipment Rating: The Load-Based Testing Approach

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.

This seminar provides an overview of the load-based testing and rating approach for unitary air conditioners and heat pumps and highlights shortcomings of the current AHRI 210/240 rating standard. Speakers explain the fundamentals of the load-based testing methodology, how the testing procedure has been developed and why such approach has the potential to better capture field performance of unitary equipment under different climate conditions, building types and variable speed operation. Speakers also address the need for validation and repeatability of the testing results as well as convergence criteria.
