What does the term "CAV" stand for in heating systems?

• A. Controlled air volume
• B. Constant air volume
• C. Centralized air volume
• D. Cold air volume

Answer: (B)

The term "CAV" stands for Constant Air Volume in heating systems. This system is designed to maintain a constant airflow rate throughout the spaces it serves. Unlike other systems, where the air volume may vary in response to heating or cooling demands, a CAV system keeps the air volume consistent. This can simplify system control and often results in more predictable performance. CAV systems are commonly used in applications where precise temperature control is less critical, as they provide a uniform airflow that can contribute to even heating and cooling across a space. In contrast, some other systems might adjust air flow based on the specific thermal load requirements, which is not the case for CAV. Understanding this distinction helps in choosing the right type of heating or ventilation system for specific building needs.
