REFRIGERAÇÃO INDUSTRIAL: análise comparativa entre sistemas de refrigeração por amônia e chiller de água gelada nos processos de uma indústria alimentícia

Abstract

This work aims to prove the improvements achieved in the processes of a food industry, through the replacement of refrigeration systems by ammonia by the chiller of cold water. The purpose is to provide the organization with obtaining better performance, reliability and cost indicators in its operations. For this purpose, the refrigeration systems of a food industry had their functionalities evidenced in the production processes. From the monitoring data of the processes and their parameters, a comparative analysis between the points of improvement became possible. These results solidify the idea of chiller water cooling systems as an alternative to ammonia systems. Through the monitoring of the processes, it was observed the efficiency in the operation of the chillers, even though the ammonia has superior thermodynamic characteristics. The completed results were satisfactory, such as the possibility of increasing production volumes (due to the greater reliability of the system), the 71.1% increase in cold room temperature compliance and a significant cost reduction of approximately 15%.
