Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the system classification?A type of HVAC system that modulates airflow volume for temperature control
2. What is the operational principle?Varies airflow rate at a constant or variable temperature, unlike CAV systems
3. What is Variable Air Volume (VAV) in a building?VAV is a smart air system that changes how much air goes into each room to keep the temperature just right.
4. How does a VAV system keep a room comfortable?It uses a small door called a damper that opens or closes when a thermostat says the room is too warm or too cool. The system can also add a little heat if the room needs it.

Variable Air Volume (VAV): An HVAC system that dynamically adjusts the volume of conditioned air supplied to a space based on demand.
Constant Air Volume (CAV): An HVAC system that delivers a fixed volume of air, modulating its temperature to meet thermal loads.
HVAC: Heating, Ventilation, and Air Conditioning; the systems responsible for maintaining indoor environmental comfort.
Thermal Load: The amount of heating or cooling required to maintain a desired indoor temperature, influenced by factors like occupancy and solar gain.
