Abstract
Various embodiments of the present disclosure optimize energy usage of an HVAC system. For example, some embodiments include a method comprising: generating a flow through a heat exchanger; determining a return temperature of fluid having passed through heat exchanger; determining a current flow of the fluid through the heat exchanger; and controlling the flow of the fluid based on a comparison of the determined return temperature with a threshold temperature, wherein the threshold temperature is dependent on the current flow.
