Contact TommyLong term performance measurement of larger GSHP systems in Sweden and abroad is performed to collect data, gain experience and compare different system’s performances. A method to measure and evaluate future performance measurements is developed.
Objective
The Annex 52 aims to survey and create a library of quality long-term measurements of GSHP system performance for commercial, institutional and multi-family buildings. All types of ground sources (rock, soil, groundwater, surface water) are included in the scope. While previous work will be surveyed, the emphasis of the annex will be on recent and current measurements. The annex also aims to refine and extend current methodology to better characterize GSHP system performance serving commercial, institutional and multi-family buildings with the full range of features shown on the market, and to provide a set of benchmarks for comparisons of such GSHP systems around the world.
Analysis procedures that help diagnose poor performance and opportunities for system performance improvements will be investigated. Multiple case studies featuring GSHP system performance measurements for systems around the world will be included and these case studies will serve as reference sets for future benchmarking.
Tasks
Task 1. Long-term measurement case studies – new and previous
Task 2. Guide for instrumentation and measurement of GSHP systems
Task 3. Guide for analysis and reporting of GSHP system performance data
