Abstract

This research explores and suggests innovative ways to optimise chiller systems in order to achieve significant energy savings while promoting healthier building environments. It is becoming more and more critical to lessen the impact on the environment and improve occupant well-being as building energy consumption increases. An essential part of heating, ventilation, and air conditioning (HVAC) systems, chiller systems are crucial for maintaining the thermal comfort of the inside of buildings. Nonetheless, a large amount of the energy used by a building is often attributed to their operation. The study begins with analysing the state of chiller systems as it is currently, identifying inefficiencies, and determining how they affect total energy usage. Following this, the research focuses at cutting-edge methods and technology for improving chiller systems, with a focus on increasing energy efficiency. These improvements help the global effort to minimise carbon footprints and fight climate change in addition to reducing operating costs. The study explores the direct relationship between indoor air quality (IAQ) and the efficiency of chiller systems. The study investigates how improved chiller systems can improve indoor air quality (IAQ) and make environments healthier. A key aspect of occupant well-being, indoor air quality affects comfort, productivity, and general health. Through simultaneously decreasing energy use and enhancing indoor air quality, this study aims to provide a comprehensive strategy for building performance. A case study is provided to validate the solutions that were suggested. It shows how chiller system upgrades were successfully implemented in a real-world building situation. The outcomes show major decreases in environmental impact, significant energy savings, and improvements in indicators of indoor air quality. It contributes to the continuing conversation about environmentally friendly building practices by highlighting how important chiller systems are to achieving energy efficiency and fostering hygienic indoor environments. The results provide insightful information to building owners, and facility managers, helping them to make decisions that will improve the environment and the well-being of their individuals.
