  • Publication number: 20210010472
    Abstract: A compressor may include a shell assembly, first and second scrolls, a piston, and a piston-retention member. The piston engages the first scroll and may be partially received within a recess defined by the shell assembly. The piston and the shell assembly may cooperate to define a pressure chamber. The pressure chamber may be in selective fluid communication with a source of working fluid to control movement of the piston relative to the shell assembly. The piston-retention member may engage the piston and a rotationally fixed structure. The piston-retention member allows rotation of the piston relative to the first scroll in a first rotational direction and restricts rotation of the piston relative to the first scroll in a second rotational direction.

  • Patent number: 10828963
    Abstract: A system is provided that includes mode, shore power, engine, and battery modules. The mode module determines whether to operate in a shore power, engine, or battery mode based on parameters. The shore power module, while in the shore power mode, runs a compressor at a speed based on a temperature within a container of a vehicle and limits the speed to a first speed. A battery is charged based on utility power while in the shore power mode. The engine module, while in the engine mode, limits the compressor speed to a second speed. The battery, while in the engine mode, is charged based on power received from an alternator/generator. The battery module, while in the battery mode, limits the compressor speed to a third speed. While in the battery mode, the battery is not being charged based on power from a shore power source and the alternator/generator.

  • Patent number: 10830517
    Abstract: Systems and methods are provided and include a variable-capacity compressor operable in a first capacity mode and in a second capacity mode that is higher than the first capacity mode. A control module is configured to switch the variable-capacity compressor between the first capacity mode and the second capacity mode based on a demand signal from a thermostat and an indoor relative humidity sensed by an indoor relative humidity sensor. The control module determines whether the indoor relative humidity is greater than a predetermined humidity and operates the variable-capacity compressor in the second capacity mode in response to receiving the demand signal from the thermostat and the indoor relative humidity exceeding the predetermined humidity.
