| Abstract | Geocool plant was the result of a EU project whose main purpose was to adapt ground source heat pump technology to cooling dominated areas. The installation was finally built by the end of year 2004 and it has been monitored since February 2005 until nowadays. In April 2011, in the framework of another European FP7 project, Ground-med, sensitivity analysis were undertaken in order to analyze the influence of the tank and the control sensor position in the system. The impact in the user comfort and the heat pump performance is studied. Results indicate that the best configuration that guarantees the user comfort corresponds to the tank on the supply and the control sensor at the outlet of the tank. Usually, heat pump manufacturers provide the control sensor located on the return line, which is the case of the installation analyzed in this work. Therefore, in order to control the temperature supply to the building (users) and adapt it to the thermal energy demand, a control algorithm was developed and implemented in LabVIEW. Results lead to potential energy savings |
