ReadMeTool version 1.5.32013-09-01To check for the latest version of this tool please see:DG ENTR Ecodesign page for Professional RefrigerationAbout this calculation toolThis calculation tool is provided to help suppliers to calculate the Seasonal Energy Performance Ratio (SEPR) for their products based upon 4 rating point measurements (or calculations) of EER.It is intended to assist suppliers to assess the seasonal performance of their products according to a methodology that is to be used under the proposed European ecodesign regulation for industrial process chillers.This tool is provided free of charge and in good faith but without guarantee of accuracy. Users should satisfy themselves that the output meets the requirement in the document: 'TRANSITIONAL METHOD FOR DETERMINATION OF THE SEPR (SEASONAL ENERGY PERFORMANCE RATIO) for INDUSTRIAL PROCESS CHILLERS (DRAFT)' which explains more details of the methodology.Temperature Reference (C):What is SEPR? Seasonal Energy Performance RatioABCDSEPR is the seasonal energy performance ratio of a process chiller. It is calculated from the EER of the process chiller at 4 different ambient temperatures and cooling loads, called rating points. The required rating points are specified in the document 'SEPR calculation method', showing for each rating point the necessary part load ratio and air dry bulb temperature for the outdoor heat exchanger.Temperature references for chillers with air-cooled and water-cooled condensers see table.AIR (inlet)

9[5C]Values in square brackets define the related ambient temperature conditionsHow to use the toolThere are two sheets: One for fixed capacity and stepless chillers; and a second for stepped capacity chillers. Use the one appropriate to the chiller.To use the spreadsheet:1. Please insert the full load rated capacity in cell D3,2. AND THEN declared rated capacity at the 3 part load rating points (B, C and D - cells D9:11)3. Insert the declared EER at 4 rating points (cells E8:11).4. In case of step capacity control also insert part load DC and EER at 3 rating points (B, C, D - cells F9:G11)The spreadsheet then calculates the SEPR automatically using a linear interpolation between the rating points A, B, C, and D and an assumption of a constant capacity for temperatures above A and below D.Feedback will be used to help improve the tool.If you have any questions or comments about the use of this tool please send an email to:ENTR-ECODESIGN@ec.europa.euPlease put the phrase 'professional refrigeration' in the subject line.
