How do you make your Heat Pumps and Chillers Operate as you Planned?
International Energy Agency Annex 52 recently published “New Guideline to Instrumentation and data” to address the challenges experienced with verification of performance of Ground Source Heat Pumps. With increasing energy prices and a focus on climate change, this guide will be useful for those pushing optimization and reliability based on documentation of performance. One of the methods described for performance analyzing is the “Internal Method”, based on thermodynamic analytics of the processes. The article describes experiences of field monitoring with this method and faults that can be identified and corrected.
