Abstract

EU regulations 2015/1095 and 2015/1094 of 5 May 2015 have been implemented for professional refrigerated counters along with the test standard EN 16825. These regulations rates most current counters as class C or D and consequently there is an ongoing development to construct top level counters (A or above). Apart from improving the cabinet construction and improving the condenser and evaporator design, advanced compressor control strategies could be part of the solution. This could be either variable speed drive (VSD) or adaptive energy optimization (AEO). Both control strategies may improve the energy efficiency but may also affect the temperature fluctuations of the stored goods. The influence of VSD and AEO was investigated using a validated dynamic model of a professional refrigerated counter using R290 and R600a. The influence was investigated according to the EN 16825 test conditions. Both VSD and AEO yield significant energy savings compared to ON-OFF control. A more constant product temperature was achieved by VSD control, while the product temperature fluctuates slightly more when applying AEO control.
