A plenum chamber is often referred to as a?

• A. Air duct
• B. Windbox
• C. Heat exchanger
• D. Fan coil unit

Answer: (B)

A plenum chamber is commonly referred to as a "windbox" because it serves as a space that facilitates the distribution of air within a ventilated system. Specifically, it acts as a central point where air pressure is equalized before being channeled into the air ducts for distribution to various areas or rooms. This chamber is crucial in HVAC systems, allowing for effective airflow management and ensuring that air is delivered evenly. In this context, other terms like air duct, heat exchanger, and fan coil unit do not provide the same function as a plenum. An air duct is a conduit for transporting air, a heat exchanger is used to transfer heat between fluids, and a fan coil unit is an assembly that includes a fan and a coil that either heats or cools the air. In contrast, the term "windbox" aptly encompasses the purpose of a plenum chamber in air distribution systems.
