Abstract: Methods and systems for recuperated superheat return are provided. A coolant is supplied in a vapor state to a compressor. The coolant compressed by the compressor is cooled with a gas cooler. The coolant cooled by the gas cooler is supplied to an inlet of a high pressure side of a recuperator. The coolant from an outlet of the high pressure side of the recuperator is supplied to a portion of a coolant circuit. The coolant is supplied back from the portion of the coolant circuit to an inlet of a low pressure side of the recuperator. The coolant in the low pressure side of the recuperator is heated with thermal energy transferred by the recuperator from the coolant in the high pressure side of the recuperator. The coolant in the vapor state from an outlet of the low pressure side of the recuperator is supplied to the compressor.

Abstract: Systems and methods are provided for decreasing thermalization time and/or increasing coefficients of performance by adding waste heat. A thermal management system may include a coolant loop and be configured to cool a target component via the coolant loop, the thermal management system may be further configured to heat the target component during a thermalization period with a waste heat source via the same coolant loop with which the thermal management system is configured to cool the target component.

Abstract: A thermal management system for regulating dissipation of multiple thermal loads during operation of an apparatus includes a two-phase pump loop (TPPL), a vapor cycle system (VCS), and a liquid thermal energy storage (TES) system integrated together to maintain the apparatus at a constant temperature. The TPPL is configured to remove heat from the apparatus; the TES system is configured to provide thermal energy storage and temperature regulation; and the VCS is configured to transfer heat to the environment. The multiple thermal loads include a primary thermal load in the form of heat from the apparatus and a secondary thermal load in the form of at least one of a housekeeping thermal load or a power electronics thermal load. The primary and secondary loads are at different temperatures with each being independently selected to be transient or steady state.

Abstract: Systems and methods for thermal management are provided. Thermal management components may include an electrical source and a cooling source. The electrical source may supply electricity to an electrical apparatus. In addition, the thermal management components store thermal energy. A controller may cause the electrical apparatus to be cooled by the cooling source and delay or suspend cooling the electrical source with the cooling source while a state of charge of the electrical source is greater than a predefined value for the electrical source. The state of charge of the electrical source may include a measurement of cooling capacity available by the electrical source.
