Seminar 35 -- Considerations for District Energy Systems Utilizing Geothermal Heat Pumps

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.

Geothermal heat pumps (GHP) have seen wide spread application in the United States as well as other locations with favorable conditions. They have proven to be efficient where accepted design guidance has been followed. At present, there is considerable interest in using GHP in district energy systems, yet little experience exists with these types of applications and no accepted design guidance is available. This session highlights some of the issues that must be considered in design of such systems and will introduce some of the factors that must be looked if designs are to be efficient and cost effective.
