A Variable air volume box regulates the temperature of a space by? A. Mixing the hot and cold air to the proper temperature for distribution B. Adjusting the flow of air into the space C. Only opening its damper when the supply air is below the space setpoint D. Reheating very cold supply air to the space setpoint when the damper is open.
A Variable Air Volume (VAV) box regulates the temperature of a space primarily by:
B. Adjusting the flow of air into the space.
VAV boxes control the amount of conditioned air delivered to a space based on the temperature requirements, allowing for efficient temperature regulation without the need for constant reheating or mixing of air.
