Estudo da eficiência energética do sistema de resfriamento – Chiller na Empresa Sumol+Compal Mz

Abstract

This work presents a study on the energy efficiency of the Chiller cooling system used at Sumol+Compal Mz, which is important to keep the right temperature during juice production. The main goal was to evaluate how well the equipment uses energy, identifying problems and suggesting ways to improve its performance. The method used combined document analysis and an experimental case study, with real data collection from the system. Variables such as electricity consumption, water temperatures at the entrance and exit, system failures, and maintenance events were monitored. The performance was measured using the Coefficient of Performance (COP), comparing results before and after maintenance work, based on the Chiller's reference standards. Results showed that, before maintenance, the system had low energy efficiency, with COP values often below ideal levels, leading to energy waste and higher costs. After the interventive maintenance, the COP improved and often reached ideal levels, supporting the idea of applying a structured predictive maintenance plan. The study concludes that energy efficiency can improve a lot with good maintenance practice, smart sensors, modern equipment and regular monitoring. Future studies can look into using renewable energy in the system and study its environmental impact. This research shows how important it is to manage with efficiency cooling systems to reduce costs, keep product quality, and protect the environment.
