  • Method for controlling an economizer
    Patent number: 6634422
    Abstract: A method of controlling an economizer is provided. A heating, ventilating, and air conditioning unit is operated in one of a heating mode and a cooling mode to provide conditioned air to a plurality of zones. A first temperature representative of air returned to the unit from the plurality of zones is sensed and a second temperature representative of the outdoor air is sensed. An economizer is modulated to increase the amount of outdoor air entering the unit when the first temperature falls below a cooling setpoint, the second temperature is greater than the first temperature, and the unit is operating in the cooling mode. The economizer is also modulated to increase the amount of outdoor air entering the unit when the first temperature rises above a heating setpoint, the second temperature is lower than the first temperature, and the unit is operating in the heating mode.

  • Method for controlling an economizer
    Publication number: 20030042015
    Abstract: A method and system for controlling the temperature of air returned to a conditioning unit in a zoned system is disclosed. The system includes a heating, ventilating, and air conditioning (HVAC) unit that has an economizer. The HVAC unit is connected to a plurality of zones by a supply duct and a return duct. A temperature sensor is provided to sense the temperature of air returning to the HVAC unit. A main control increases the amount of outdoor air entering the system through the economizer when the temperature of the returned air is excessively warm or excessively cold.
