Question: 1 / 400

Why is system cycle efficiency important in HVAC?

It determines the physical size of the system

It directly impacts energy consumption and operational costs

System cycle efficiency is important in HVAC because it directly impacts energy consumption and operational costs. When the cycle efficiency is high, the system effectively converts input energy into useful heating or cooling output. This means less energy is wasted during the process, leading to reduced energy bills for operating the HVAC system. Efficient systems not only align with energy conservation goals but also lower environmental impacts by minimizing energy usage. In contrast, systems with low cycle efficiency tend to consume more energy to achieve the same output, which can significantly increase operational costs over time. Therefore, optimizing cycle efficiency is a key consideration in the design and selection of HVAC equipment.
