Part 2 Certification Program for GeoExchange Designers

Certification Program for GeoExchange Designers Part 1. Dr Jim Bose, Ph.D., P.E. Introduction to CDG course. IGSHPA has designed a program to offer advanced training towards certification as a GeoExchange Designer (CGD). From an introduction to the technology to a complete review of the design process, participants learn the specific information they need to know. IGSHPA has entered into a cooperative endeavor with the Association of Energy Engineers (AEE) and the Geothermal Heat Pump Consortium (GHPC) to provide training for the Certified GeoExchange Designer Program. Participants will receive a copy of the Closed-Loop/ Ground-Source Heat Pump Systems Installation Guide, as well as other manuals in the CGD Notebook.

Where the waters (static) were 120-140 ft deep,

to get r-22 heads down to 210-200 psig at 3g/"ton", it was requiring OVER 230 ft of vertical bore per 10-day continuous cooling building ton...

[MelTune]

that is per compressor-cooling ton:

efficiently loaded,

you must devide ~ 1.2 compressor heat output by .88 resulting heat of extraction (cooling in the field) and you will see the addages of 180-175 ft/ton are really 205-210 in Ohio to PA...

(52-54 deg Earth loops vertical bores/ 300 ft'rs

And today we still see in 2008 that it was 205 to 210 ft in a static-wet borehole (waters within 30-40ft of surface)
