Thermal Conductivity Testing

Thermal conductivity testing, also known as “in situ testing,” is done for vertical loop installations for commercial buildings.

A bore hole that can be used for the future ground loop is installed with polyethelene pipe and grout. A controlled test measuring time, water flow, and rejected heat is conducted for a period of 36-48 hours. The data is recorded and the results are analyzed to help determine the final design of the ground loop including the pipe length and size, number of bore holes, spacing of bore holes, and the type of grout to be used.

Air Connection provides thermal conductivity tests for their own projects as well as providing this service to anybody considering designing a geoexchange system.
