Abstract: A climate-control system includes a working fluid circuit and a storage tank. The working fluid circuit has a first compressor, a first heat exchanger, a second heat exchanger, a flash tank, and a third heat exchanger. The first heat exchanger receives working fluid discharged from the first compressor. The flash tank is disposed downstream the first heat exchanger and includes an inlet and first and second outlets. The first outlet provides working fluid to the third heat exchanger disposed between the flash tank and the first compressor. The second outlet provides working fluid to the first compressor. The storage tank contains phase-change material that is thermally coupled with the second heat exchanger of the working fluid circuit.

Abstract: A compressor includes a housing, a partition, a first scroll, a second scroll, and a thermal protection system. The partition is disposed within the housing and defines a suction chamber and a discharge chamber. The partition includes a discharge passage in fluid communication with the discharge chamber. The thermal protection system includes a positioning body and a displacement member. The positioning body is coupled to the second scroll and translatably disposed within the discharge passage. The displacement member is disposed between the positioning body and the partition and configured to translate the second scroll relative to the first scroll between first and second positions.

Abstract: The present disclosure provides a high-strength thermally insulative partition assembly (e.g., muffler plate) for use in a scroll compressor. The assembly includes at least one metal plate and an insulating region. The insulating region may have at least one insulating material or may be a low-pressure or vacuum chamber. The partition assembly serves to minimize heat transfer between a low-pressure refrigerant on the low-pressure, suction side and a high-pressure, high-temperature refrigerant on the high-pressure, discharge side of the compressor. The insulating region may be sandwiched between multiple metal plates. The insulating region may be coated on the metal plate. The insulating region may also be a preformed component or mask that is coupled to the metal plate via a mechanical interlock system.

Abstract: System and methods are provided and include a compressor operable in a refrigeration circuit, a first sensor detecting high-side data indicative of a high-side operating condition of a high-pressure side of the refrigeration circuit, a second sensor detecting low-side data indicative of a low-side operating condition of a low-pressure side of the refrigeration circuit, and processing circuitry. The processing circuitry receives the high-side data and the low-side data, determines a high-side fault, a low-side fault, a severe high-side fault, or a severe low-side fault based on the high-side data and the low-side data, operates the compressor in a limp-along mode by restricting power to the compressor or reducing a capacity of the compressor in response to determining at least one of the high-side fault and the low-side fault, and shuts down the compressor in response to determining at least one of the severe high-side fault and the severe low-side fault.

Abstract: A compressor may include a shell assembly, a non-orbiting scroll, and an orbiting scroll. The shell assembly may define a discharge chamber. The non-orbiting scroll includes a first end plate and a first spiral wrap extending from the first end plate. The first end plate may include a variable-volume-ratio port. The orbiting scroll may be disposed within the discharge chamber. The orbiting scroll includes a second end plate and a second spiral wrap extending from the second end plate and cooperating with the first spiral wrap to define a plurality of fluid pockets therebetween. The second end plate may include a discharge passage in communication with a radially innermost one of the fluid pockets and the discharge chamber. The variable-volume-ratio port may be disposed radially outward relative to the discharge passage and may be in selective communication with the radially innermost one of the fluid pockets.
