This product is a PDF that 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.This seminar is designed to explain the engineering requirements of a hybrid ground source heat pump system. It will demonstrate predictable performance that results from detailed assessment versus rule of thumb. It will also provide the attendee insight into tools that are available to insure a well designed system.Computer Modeling for Ground Heat Exchanger DesignEd Lohrenz, MemberProduct contains: recorded presentation, slides (PDF format), audio (mp3 format)Three Hybrid Ground Source Heat Pump Systems in Both Heating and Cooling Dominated ClimatesScott P.
