WebMar 10, 2024 · The air handler will deliver a constant temperature of 55ºF (13 ºC) supply air to the VAV boxes. While the supply air temperature stays constant the volume (CFM) of air will vary based on the total demand of all the zones on the system. There are several control strategies to adjust the speed of the fan which we’ll discuss below. WebFan at same speed-When the regulator of the fan is untouched and the fan rotates at the same speed, we can say that the fan is rotating with constant angular velocity. Revolution of Moon around Earth- The Moon takes equal amount of time to complete one revolution around Earth, we can say that it follows a constant angular velocity motion.
