Abstract: Chiller control systems and methods for chiller control use iterative modeling of cooling towers, heat exchangers, and pumps to determine the feasibility of integrated free cooling and the ability to take advantage of free cooling. The control systems and control methods can further include selecting the parameters for operating in the free cooling or integrated free cooling mode to improve efficiency and/or reduce energy consumption when operating in these modes. The models can have inputs and outputs that feed into one another, and converge at a solution over multiple iterations. The feasibility of integrated free cooling can be based on providing cooling to a cooling load process fluid at a heat exchanger. The availability of free cooling can be based on the cooling provided at the heat exchanger achieving a target temperature for the cooling load process fluid.

Abstract: An apparatus and method for controlling the conditioning mode of a climate control device, such as a rooftop unit, that is servicing multiple connected terminal unit. The improved process may include determining a conditioning mode error for the connected terminal units. The conditioning mode error may be an integrated error value that is based on a temperature deviation integrated over the duration of the temperature deviation. The process may also determine a cooling mode error and a heating mode error. The cooling mode error and the heating mode error may be based on the conditioning mode error for the terminal units associated with cooling conditions and heating conditions, respectively. The process may further compare the cooling mode error and the heating mode error, and it may also adjust the conditioning mode of the climate control device based on the comparison.

Abstract: Multi-compressor chiller systems can be efficiently operated by determining real time efficiency curves for the compressors currently in operation, along with any compressors that may be added to address demand, and using these efficiency curves to determine changes to compressor operation to improve efficiency in meeting chiller demand. The efficiency curves can be parabolic curves. The data used to determine the efficiency curves can be obtained through operation at a variety of lift points and a variety of load points within those lift points. The efficiency curves can be solved to find intersections where there may be staging points for adding or subtracting compressors from operation to efficiently meet demand. This operation can be automated through a controller of a control system for the multi-compressor chiller system.

Abstract: A method and apparatus for controlling a load facility in response to a demand event. The method includes defining a plurality of resources of the load facility based on user input, establishing a response strategy for the demand event, and organizing the resources into the response strategy that specifies the resources and times during the demand event at which the resources are called to execute the one or more measures to reduce power consumption of one or more of the electrical devices, different ones of the resources called at different times during the demand event, and at least one of the resources called to execute the one or more measures, and further including executing the response strategy to reduce demand on the power grid from the load facility during the demand event.
