GECCO Complete TRT at University of Nottingham Maths Building

The test has been carried out in order to provide information on the ground conditions to verify the design of a GSHP installation for the new Maths Building at The University of Nottingham.

The test borehole with a diameter of 115mm was progressed to a depth of 100m using rotary drilling methods. A 40mm OD PE100 geothermal loop was then installed and grouted up with high thermal conductivity grout. The test was conducted 7 days after the grouting of the borehole, to prevent any exothermic reaction from the curing of the grout affecting the results of the test.

The Thermal Response Test has been carried out in accordance with IGSPHA (2007) standards, generally based upon the ASHRAE recommendations.

The test is carried out in three phases, the first phase entails pumping of the fluid through the loop with no power applied, measurements of the flow and return temperatures are taken at intervals of 20 seconds. Following the initial two hour phase the heating is turned on and again temperatures are recorded at intervals of 20 seconds for a minimum period of 48 hours. Following this period of applied power the power is then turned off whilst maintaining the flow until the borehole flow and return temperatures have recovered to approximate pre-test levels.

Graphical outputs of the data, namely temperature of the flow & return fluid T_f & T_r, average temperature of the flow & return, T_ave, and flow throughout the duration of the test were included within the test report.

A diesel generator provided the power input for the electric heater and was set to 3900W. This heat input was determined prior to the test based upon typical guidelines of between 30 and 80W/m. Due to the depth of the borehole being 100m this was specified to be 39W/m.

The flow rate within the loop is maintained at a rate that provides turbulent flow for the 35mm ID geothermal loop installed and is in line with that, that would be provided for the working system in order to achieve a temperature differential of 3 to 5 degrees. This is in line with a typical heat pump manufacturer's operating conditions.
