Chiller Plant Optimization is a business term used to describe the process of improving a chiller cooling system’s performance in order to save energy, reduce operating costs, and improve reliability. It involves evaluating the system components and optimizing the design to maximize their efficiency and reduce overall running costs. By looking at factors such as motor and chiller size, piping connections, thermostat placement, sensors, flow controls and refrigerant type, it is possible to make an already efficient system even better. With the right tools, experience and expertise, chiller plant optimization can result in big savings for businesses with older chiller systems.
