Abstract: Methods, apparatus, and systems for load control for cooling systems are provided. Coolant flows through a plurality of cooling units in a cooling system. The coolant flow is halted for each cooling unit that is undergoing a defrost cycle. Each cooling unit is configured to start a first defrost cycle at a random time within a predetermined time range after the cooling unit is started or powered on. After the first random start defrost cycle, a regular periodic defrost cycle may be maintained. Thus, the cooling units may be powered on simultaneously while still providing desynchronized defrost cycles, enabling the cooling system to maintain adequate coolant flow and heat load to avoid deleterious stop and restart cycles.

Abstract: A rotary mechanical system includes an electric machine, such as an electric motor, and a housing at least partially housing one or more components of the electric machine. The housing defines an electrical cavity and a coolant cavity. The electrical cavity houses one or more electrical components, such as a stator, of the electric machine. The coolant cavity is configured to receive a liquid coolant, such as ethylene glycol and water, from a liquid coolant system. The housing is configured to seal a two-phase refrigerant within the electrical cavity to transfer heat from the one or more electrical components to a wall of the electrical cavity and from the wall of the electrical cavity to the liquid coolant.

Abstract: A hybrid emergency power unit for an aircraft comprises a controller, a generator-motor coupled to the controller, a hydraulic pump coupled to the generator-motor, a battery pack coupled to the controller, and a turbine coupled to the generator-motor. During a bleed air mode, the turbine and the generator-motor supply electricity to the controller, which is configured to rectify an output of the generator-motor for consumption by one or more electrical systems on the aircraft. During an augment mode, when bleed air provides insufficient power, the controller is configured to draw at least some power from the battery pack and convert the output of the generator-motor for consumption by the one or more electrical systems. During an emergency mode, the controller is configured to draw electricity from the battery pack and provide power to drive the generator-motor, which in turn drives the hydraulic pump and provides electrical power to aircraft systems.

Abstract: A scroll compressor includes a fixed scroll; an orbiting scroll that interfaces the fixed scroll; an Oldham ring that interfaces the orbiting scroll and has a pre-unbalanced force profile; and a motor shaft that interfaces the Oldham ring. The Oldham ring pre-unbalanced force profile is in the form of a sine wave. One of the shaft and the orbiting scroll has an imbalance weight portion; wherein the imbalance weight portion provides a weighted force profile that is 180° opposite of the pre-unbalanced force profile of the Oldham ring and produces in the Oldham ring a post-unbalanced force profile that is substantially a flat line.
