This program integrates concepts familiar to HVAC engineers with information necessary to design ground heat exchangers. The program user begins by entering the results of a cooling load and heat loss calculation. Ground properties are entered with help from information tables. Data is entered in easy to use screens, which can be easily modified.
Output appears in four formats.
The program selects the heat pump model for each zone and specifies the required coil length. Hybrid GHP systems can also be designed. A variety of system performance data are listed. These include maximum block loads, required water flow rates, peak demands and average heat pump and system efficiencies, The program allows the user to easily change any input and quickely determine resulting effects on ground coil size and system performance. Over 1200 potential GHP designers have attended one of the 50 design seminars conducted by Steve Kavanaugh, developer of GchpCalc.
