What is the primary purpose of zoning in HVAC systems?

• A. To reduce installation costs
• B. To control airflow between rooms
• C. To control temperatures in different areas
• D. To increase the overall system size

Answer: (C)

The primary purpose of zoning in HVAC systems is to control temperatures in different areas. Zoning allows for the division of a building into separate areas or "zones," each of which can be controlled independently. This enables a tailored heating and cooling approach that accommodates the varying needs of different spaces based on usage, occupancy, and other factors. For instance, some areas of a building may require more heating or cooling than others due to sunlight exposure, the number of occupants, or use patterns. By controlling the temperature in each zone, energy efficiency is improved, as the system can operate more effectively and only as needed in each area, leading to cost savings on energy bills. This method enhances comfort for occupants by ensuring that each zone is maintained at a desired temperature without over-conditioning or under-conditioning other areas. The other options touch on aspects related to HVAC but do not align with the primary objective of zoning systems. Reducing installation costs, controlling airflow, or increasing system size are not the core functions addressed by zoning; rather, they may be secondary effects or considerations in the design and implementation of an HVAC system.
