Análise da eficiência e performance das características do sistema de refrigeração de uma indústria de bebidas: estudo de caso

Abstract

The search for a decrease in the consumption of electric energy and the increase of efficiency in refrigeration systems is very strategic for the industries, because, in this way the simulation of such systems plays a fundamental role in the project, since it optimizes steps and wastes physical resources. This study aims to describe and analyze a refrigeration system using Ammonia refrigerant (R-717) in the beverage industry, introducing the concept of the refrigeration cycle and demonstrating each component used in the cycle. For that, experimental data were collected directly in the industrial plant and, thus, the various thermodynamic states and the energy and enthalpy balance, enabled the analysis of cycle performance. The results indicated an improvement of the coefficient of performance (COP) by reducing the evaporation temperature of the system, being the coefficient 6% higher than the current one, making possible a possible investment.
