Large Diameter, Shallow Bore Heat Exchangers for Ground-Source Heat Pumps

Webinar July 8, 2020

Ground-coupled heat pumps reduce cooling load in summer and heating load in winter by using the relatively constant temperature of the earth as the heat exchange medium instead of the outside air. By exchanging heat with the mild ground temperatures, ground-coupled heat pumps are more efficient than air-source designs and use less power during peak electricity demand. The biggest barrier to more widespread adoption of this technology is the cost.

In this webinar, researchers will describe the results from a project investigating a lower cost heat exchanger design for ground-source heat pumps. Researchers developed and validated modeling tools for simulating a ground heat exchanger (GHE) technology, and used those models to estimate the performance of these systems in multiple California climate zones. These modeling tools can be used to facilitate proper GHE sizing for a full range of applications and should streamline acceptance of this emerging technology.
