Claim:
1. A method for managing thermal loads comprising the steps of: providing an ammonium carbamate-based thermal management system comprising a flow controller, a primary heat exchanger coupled to the flow controller, a vacuum source coupled to the primary heat exchanger, and a pressure controller coupled to the primary heat exchanger and the vacuum source, wherein the primary heat exchanger comprises ammonium carbamate; applying heat from a thermal load to the ammonium carbamate-based thermal management system, wherein heat from the thermal load is absorbed into a coolant fluid to provide a heated coolant fluid, wherein the heated coolant fluid is introduced into the primary heat exchanger using the flow controller, and wherein the thermal load is within a temperature range greater than or equal to about 20° C. and less than or equal to about 100° C.; transferring heat from the heated coolant fluid to the ammonium carbamate, wherein the ammonium carbamate endothermically decomposes into ammonia gas and carbon dioxide gas; adjusting an overhead pressure of the primary heat exchanger, a system temperature of the primary heat exchanger, or a coolant fluid flow rate to achieve a desired amount of heat transfer from the thermal load to the ammonium carbamate; and removing the ammonia gas and the carbon dioxide gas from the ammonium carbamate-based thermal management system using the vacuum source, the vacuum source being controlled by the pressure controller.
