Abstract: A method of self-balancing a plurality of mechanical components within a temperature control unit of an HVAC system. Each mechanical component is adjustable by the controller to vary airflow within the temperature control unit. For each mechanical components, a property is measured. An estimated condition of the mechanical component is calculated based on the measured property and known qualities of the temperature control unit. A desired condition for the mechanical component is determined based on a desired air condition within the HVAC system or building envelope. The estimated condition of the mechanical component is compared to the desired condition of the component. The condition of the mechanical component is changed using a controller to more closely align the estimated condition to the desired condition to achieve the desired indoor air condition. Steps are repeated until the difference between the estimated condition and desired condition is within a threshold value.

Abstract: An air conditioning system includes a housing defining a first airflow path therein between an outside air inlet over a cooling coil and an outlet for delivering outside air from the outside air inlet over the coil to the outlet, a second airflow path between a return air inlet over the cooling coil and to the outlet for delivering return air over the cooling coil, and a third airflow path between the return air inlet and the outlet for delivering return air through the housing without passing over the cooling coil. The system includes outside, return, and bypass air dampers that are sequentially moveable between open and closed positions for directing air through or preventing air from entering the first, second, and third airflow paths, respectively. A controller independently controls the opening and closing of each damper in response to data received from the sensor.
