  • Temperature control system for zoned space
    Patent number: 5180102
    Abstract: A variable air volume control system has a temperature system management device which calculates an air flow setpoint in a temperature zone as a function of a proportional term that accommodates gross temperature-setpoint errors, and integral term that provides heating or cooling load matching, and a derivative term that accommodates rapid fluctuations in the cooling or heating load, and communicates the flow setpoint to a terminal control unit to adjust the air flow to a space. The terminal control unit will implement a flow setpoint as a function of the gross error in temperature in the space and a default temperature comfort setpoint upon failure of the temperature system management device to maintain a temperature in the zone.

  • Duct pressure synthesis for air distribution system
    Patent number: 5167366
    Abstract: An air terminal flow detection scheme in an air distribution system effective for developing static pressure indications of the plenum of the air terminal from change in the flow through the air terminal over the period of time of the change.

  • Pressure independent control for air distribution system
    Patent number: 5123592
    Abstract: An air terminal adjustment method to achieve an air flow setpoint wherein the time to achieve the setpoint is determined by calculating the difference between the flow setpoint and an actual flow and then dividing the difference by a change in flow per unit time. The time to achieve the setpoint adapts to changes in static pressure in the air terminal.
