Downhole Heat Exchanger System for Sharpstein Museum, Brannon Cottage, and the Community Center, Calistoga, CA. Feasibility Study

摘要

Based on the results of the test drilling at the Sharpstien Museum and Community Center, a well at the site should provide space heating for the Museum and Community Center, and domestic hot water for the Community Center utilizing a downhole heat exchanger (DHE). Although the temperatures observed in the well are very low, a suitable system can be designed and installed. Not including the cost of the well and testing, which is assumed to be borne by the California Energy Commission for demonstration and scientific research purposes, the simple payback is between 4.6 and 7.5 years depending on the cost of the experimental convection promotor.
