Prediction of the thermal performance of horizontal-coupled ground-source heat exchangers

The thermal performance of a horizontal-coupled ground-source heat pump system has been assessed both experimentally and numerically in a UK climate. A numerical simulation of thermal behaviour of the horizontal-coupled heat exchanger for combinations of different ambient air temperatures, wind speeds, refrigerant temperature and soil thermal properties was studied using a validated 2D transient model. The specific heat extraction by the heat exchanger increased with ambient temperature and soil thermal conductivity, however it decreased with increasing refrigerant temperature. The effect of wind speed was negligible.

With Unusual Speed Officials Slap Exxon with Oil Spill Lawsuit. Why? June 19, 2013
The suit that state and federal officials recently filed could signal they are especially upset with Exxon's conduct. It could also be politics as usual. By David Hasemyer The lawsuit that state and federal officials in Arkansas filed last week against ExxonMobil is unusual, pipeline experts say, because government agencies usually wait much longer—some […]
