Refrigeration End-Use Performance Data Share
BPA recognizes Commercial Refrigeration as an important end use in the commercial energy savings portfolio for the region.
In 2012, the Energy Efficiency Engineering team became aware of a refrigeration performance monitoring system – ClimaCheck – and decided to use the equipment to monitor commercial refrigeration systems in the BPA region.

As part of its overall strategy to meet its energy goals, NAVFAC partnered with NREL to rapidly demonstrate and deploy cost-effective renewable energy and energy efficiency technologies.
“Detta projekt visar att det finns mycket att vinna på en noggrann uppföljningsfas”
The energy savings opportunity in commercial buildings varies according to building type, systems, climate zone, construction type, and occupant density, among other factors. To translate this complexity and opportunity into actionable, strategic approaches, DOE’s Building Technologies Office (BTO) conducts a research, identification, and evaluation exercise.
“Early detection of faults is always cost effective and prevents long test periods from becoming useless.
– “Det är ofta SI och Så med mätning och uppföljning”, text by : Jörgen Olsson
Analysis can be done for example with equipment from ClimaCheck for a short interval or with a permanent installation with connection to the internet, so it is possible to follow the variation in performance. The ClimaCheck system also provides other valuable information about the performance of the system.

Future work should focus on directly measuring or better estimating thermal loads on the refrigeration systems. The following are suggested methods to improve thermal load predictions, which will minimize uncertainty in system sizing and help to further reduce risk to stakeholders:
1. Installation of a Climacheck (or similar) system to directly and accurately measure thermal loads on the refrigeration systems being analyzed.
