Draft of the MEPS and HEPS for industrial refrigeration compressor in Thailand

Abstract

This study aimed to find the high energy efficiency standard (HEPS) and minimum energy efficiency standard (MEPS) of industrial refrigeration compressors that suitable for Thailand. The energy efficiency data of each sample product was obtained from the specification providing by its manufacturer. The energy efficiency data of 1,006 products were found and used for study HEP and MEP values in this study. They were categorized into 2 groups consists of 344 products and 662 products for low and medium evaporating temperature groups, respectively. All of them were coefficient of performance (COP) measured according to the EN13771-1:2016 and describing the results in accordance with EN12900:2013. The results show that evaporating temperature has dominant effect on COP. It was found that the COPs of low and medium evaporating temperatures should not below 0.7911 + 0.7392 × [Cooling capacity/(Cooling capacity + 1.049)] and 1.3774 + 1.2934 × [Cooling capacity/(Cooling capacity + 1.785)]; respectively, for HEPs and 0.4307 + 0.7392 × [Cooling capacity/(Cooling capacity + 1.049)] and 0.8354 + 1.2934 × [Cooling capacity/(Cooling capacity + 1.785)]; respectively, for MEPs. It is noted that cooling capacity’s unit is kW.
