Reference data sets for validating GSHP system models and analyzing performance parameters based on a five-year operation period

• The data acquisition system of the GeoCool installation is described.
• A data processing tool that automatically processes the raw data is presented.
• Calculations needed to obtain the system performance parameters are described.
• Results obtained from the data processing tool are presented and discussed.
• Reference data sets are provided.

A GeoCool ground source heat pump installation has been operating since February 2005, and it has been completely monitored since then. The performance analysis of the system during its first years of operation was presented in previous publications. This paper presents a detailed description of the analysis tool used, together with the results and analysis for thermal loads, performance factors, and load ratios over five years. It also provides a complete reference data set (water temperatures, flow rates, and power consumption) which can be used by researchers for model validation of this kind of installations. An example of software validation with experimental data is presented.
