Comparative Analysis of Air Compressor Energy Efficiency Standards of China, EU and USA

EasyChair Preprint 14556

Abstract

China has established a comprehensive standardization framework for air compressors, encompassing both product specification and energy efficiency standards. This paper presents the latest iteration of “GB 19153-2019  Minimum allowable values of energy efficiency and energy efficiency grades for displacement air compressor”[1] (GB19153), elucidating its scope, energy efficiency metrics, classification criteria, and testing parameters.

Moreover, this paper delineates China's recent endeavors in enhancing the efficiency standardization of compressed air systems, as articulated in the industry standard" T/CGMA 033001-2018 Guide to Energy Efficiency Classification for Compressed Air Stations." [2] (T/CGMA033001) . This standard proffers a classification scheme for the energy efficiency of compressed air stations within China, exhibiting a discernible 10% variance in efficiency between adjacent grades and a notable 45% discrepancy between Grade 1 and Grade 5. Grade 5's energy efficiency level typifies the average performance of extant compressed air stations in China.

Furthermore, a comparative analysis of air compressor minimum energy performance standard (MEPS) across GB19153, the EU Lot31 proposal "Possible requirements for compressors for standard air applications DRAFT ECODESIGN REGULATION"[3] (Lot31) , and the US standard "Energy Conservation Program: Energy Conservation Standards for Air Compressors[4]"(ECSAC) is conducted, encompassing facets such as product scope, energy efficiency metrics, tolerance thresholds, testing conditions, and MEPS stipulations.

It is recommended that the potential for energy savings in compressed air systems far exceeds that of individual components. As efforts in energy conservation deepen, emphasis will inevitably shift towards enhancing system-wide energy efficiency, particularly concerning the energy conservation of compressed air stations.
