A method of coordinated flow control in a heat exchanger system includes adjusting a position of a variable actuator of the heat exchanger system if an associated monitored temperature of the heat exchanger system needs adjustment, determining if the adjusted position of the variable actuator is within a predetermined range of positions, adjusting a position of a discrete actuator of the heat exchanger system if the adjusted position of the variable actuator is not within the predetermined range of positions, and resetting the position of the variable actuator in response to adjusting the position of the discrete actuator.

Coordinated flow control

A system includes a heat exchanger; a variable actuator in operative communication with the heat exchanger and configured to vary a flow of a first fluid through the heat exchanger in a continuous manner; a discrete actuator in communication with the heat exchanger and configured to vary a flow of a second fluid through the heat exchanger at one of at least two discrete rates; and a controller in communication with the variable actuator and the discrete actuator, wherein the controller is configured to adjust the position of the variable actuator within a range dependent upon a current position of the discrete actuator.

Sensing, actuation of apparatus, and a control algorithm for use in automatically controlling an air-conditioning system by sensing multiple conditions and responding by actuating the mechanical components of the air-conditioning system to optimize the temperature of the coolant fluid, provide improved zone temperature control, provide status of system components, and provide an alert if there is overheating of a supply side system mechanical component.
