Abstract

A method of controlling a variable-air- volume heating, ventilating, and air-conditioning system, includes causing the static pressure in a duct to be maintained at a desired static pressure by controlling the speed of a fan in proportion to the square root of the ratio of a desired duct static pressure setpoint to a measured duct static pressure. A HVAC system employing the method is further included.
