Assessment of energy and environmental performance of low-charge multiplex refrigeration system

Abstract

Low-charge multiplex refrigeration system (LCMRS) used in supermarket application is defined as low-energy performance in cooling system considered as important energy consumers. In this context, this study primarily examines energy and exergy performances of the LCMRS and expresses their changes in a supermarket application. Additionally, environmental performances of LCMRS were evaluated based on different refrigerants. In the study, the effects of R-404A, R-407C, and R-152a refrigerants on performance were also examined, and it was found that R-152a and R-407C gases have significant advantages in terms of performance and environmental impacts.
