What does the term 'zone control' refer to in HVAC?

Zone control in HVAC refers to the ability to independently control temperatures in different areas or zones of a building. This system typically involves the use of multiple thermostats, dampers, and control systems that allow for more tailored heating and cooling based on the specific needs of each area, rather than relying on a single temperature setting for the entire space. This approach enhances comfort and energy efficiency, as it allows for varying temperature requirements based on factors such as room usage, occupancy, and sunlight exposure.

This concept is particularly beneficial in larger buildings or spaces with varying heating and cooling demands because it optimizes energy use by directing air conditioning and heating resources only where they are needed, thereby avoiding waste and improving occupant satisfaction. Each zone can have its own preferred temperature, leading to a more comfortable environment overall.
