What does Energy Efficiency refer to?

Energy Efficiency refers to the relationship of energy consumed to useful work performed. This concept is crucial in HVACR applications as it emphasizes how effectively energy is transformed into useful outputs, such as heating or cooling, without unnecessary waste. A system that operates with high energy efficiency uses less energy to achieve the same level of performance compared to a less efficient system, which can lead to lower operational costs and reduced environmental impact. Understanding this relationship helps HVACR professionals design and select systems that not only meet performance criteria but also contribute to sustainability by minimizing energy consumption.
