Claim Text:
1. A control device for a thermal energy management system having more than one varying thermal loads, the control device comprising: a supply temperature sensor positioned in a main supply line upstream of the more than one varying thermal loads; a return temperature sensor positioned in a main return line downstream of the more than one varying thermal loads, wherein the more than one varying thermal loads are fluidly connected to and branched from the main supply line and main return line; and a controller in communication with the supply temperature sensor and the return temperature sensor, the controller being configured to calculate an actual thermal energy difference across the more than one varying thermal loads using a temperature difference between a supply temperature and a return temperature from the supply and return temperature sensors respectively, and to maintain a desired thermal energy difference by controlling a flow rate of the system and a variable supply temperature of the system in response to a changing actual thermal energy difference such that the actual thermal energy difference is equal to the desired thermal energy difference across the more than one varying thermal loads, thereby instantaneously matching a thermal demand on the more than one varying thermal loads, wherein the controller is configured to increase the flow rate of the system solely based on the temperature difference increasing, and wherein the controller is configured to decrease the flow rate of the system solely based on the temperature difference decreasing.
