The instrumentation guideline draft document for large GSHP systems was presented by the instrumentation guideline sub-committee. The draft document points at two key instrumentation issues: hardware and data. The guideline will give recommendations on calibration, data collection intervals and data filtering. It was decided that one chapter in the guideline will be dedicated to distributed thermal sensing (DTS) in GSHP performance monitoring applications.<\/p>\n<p>Within Annex 52, the aim is to identify and recommend performance indicators that will allow for evaluation of the source side ground circuit, as well as the heat pump unit performance and the load side circuit performance, including supplementary heating and cooling. Evaluation of these three performance levels should be useful for commissioning, fault detection, system optimization and future system development. At the meeting in London, suitable indicators and required instrumentation were discussed, as a first step towards a performance analysis and indicator guideline.<\/p>\n<p><em>UK GSHP workshop<\/em><\/p>\n<p>In conjunction with the experts\u2019 meeting in London, the UK energy agency BEIS arranged a national workshop focusing on GSHP projects with UK participation.
