    Abstract: A heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a heating fluid circuit, a cooling fluid circuit, and a storage fluid circuit. A thermal system of the HVACR system absorbs energy from the storage fluid circuit and rejects it to the heating fluid circuit. The storage fluid circuit includes thermal storage tanks containing thermal storage material that can provide energy for heating or absorb energy for cooling depending on the state of the thermal storage material. Heating can be provided using the heating fluid circuit and the heat provided by the thermal system. Cooling can be provided using the cooling fluid circuit by absorbing energy from the conditioned space using a cooling fluid and rejecting energy from the cooling fluid to the storage fluid circuit including the thermal storage tanks. The thermal storage tanks can also have heat added to them using an air source heat pump system to provide sufficient storage for heating operations.

    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.
