What is PD IEC/TR 63061 – Adjusted volume calculation for refrigerating appliances about?
PD IEC/TR 63061 is a technical report, sets out a uniform calculation method for the parameter of adjusted volume that is commonly employed in the calculation of energy efficiency household refrigerators, freezers, and refrigerator-freezers.
Who is PD IEC/TR 63061 - Adjusted volume calculation for refrigerating appliances for?
BS EN 63061 on refrigerating appliances applies to:
- Freezer manufacturers
- Refrigerator manufacturers
Why should you use PD IEC/TR 63061 - Adjusted volume calculation for refrigerating appliances?
One of the most common approaches used to define the energy efficiency of refrigerators and freezers is the concept of adjusted volume. This approach was developed in the 1980s and essentially weights the volume of each compartment in proportion to the temperature difference between the compartment temperature and the ambient temperature outside of the appliance. While there is a range of other possible approaches that can be used, adjusted volume is one method that is widely used around the world.
While the concept of adjusted volume is widely used and well accepted, it appears that there are some variations and differences in how this parameter is calculated and applied in different countries. This creates anomalies in how energy efficiency parameters are calculated between countries. While the exact approach used to define adjusted volume is ultimately a matter for individual countries, it is hoped that this document will provide a clear explanation of the approach and will provide a sound basis for how this can be applied in different conditions, as dictated by local policies. The purpose of PD IEC/TR 63061 is therefore to encourage alignment in national approaches to the definition and application of adjusted volume.
PD IEC/TR 63061 will foster dialogue and cooperation between countries and encourage the use of more uniform approaches to the calculation and application of adjusted volume, where this is used in energy efficiency policies and programs. PD IEC/TR 63061 will further encourage trade, development of more uniform efficiency benchmarks and overall improvements in energy efficiency globally.
