Abstract
A system and method for modulating the speed of a fan over a period of time to maintain the space temperature of a room. The system and method involves the use of a CRAC unit or a fan coil unit. In an embodiment, the system is comprised of said CRAC or fan coil unit, a variable frequency drive, fan motor, fan, room temperature sensor, and supply air temperature sensor. Based on the collected room and supply air temperature values, a novel control sequence determines how to best modulate the speed of the fan motor over a period of time. Using this system and control method, the space temperature can be controlled at the desired temperature.
