Seminar 10 -- Current Research in Long-Term Performance Monitoring and Analysis of Ground-Source Heat Pump 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.

The long-term performance of ground source heat pump systems is a topic which is rarely reported in literature, due primarily to the inherent difficulties in accurately measuring system performance over many years. Additionally, the best practices for performing such studies have yet to be determined. This seminar presents the results from several research studies where the long-term performance of several different groundsource heat pump systems are discussed. The analysis methods used to determine system performance are discussed and the results are presented.
