Title: ADVANCED GROUND THERMAL CONDUCTIVITY TESTING
Abstract:
A new device and method for more quickly and accurately performing a Thermal Response Test (TRT) to determine the Thermal Conductivity (TC) of the ground for use by a Geothermal Heat Pump (GHP) system. Existing TRT methods require testing for about 48 hours and require a very stable source of heat. This invention reduces the testing time required to under 24 hours and removes the requirement for a stable heat source, and thus will decrease the cost for TC testing and increase its use. Further, this new device and method provides more information about the thermal properties of the earth being tested than prior techniques.
