Question: 1 / 400

What does the term 'zoning' in HVAC systems refer to?

Maximizing the energy efficiency of heating systems

Dividing a building into separate areas to control temperature independently

Zoning in HVAC systems specifically refers to the practice of dividing a building into separate areas or zones that can be controlled independently for temperature regulation. Each zone is typically equipped with its own thermostat, which allows for customized heating and cooling according to the specific needs of that area. This approach provides increased comfort for occupants and can enhance energy efficiency by only conditioning spaces that are in use or require specific temperature settings.

By having the ability to manage temperatures in various zones separately, HVAC systems can avoid unnecessary energy consumption that occurs when heating or cooling unoccupied areas. This not only leads to a more comfortable living or working environment but also contributes to lower utility bills and improved overall system performance.
