    Abstract: A climate-control system includes a first compressor, a second compressor, a first heat exchanger, a second heat exchanger, and a third heat exchanger. The first compressor includes a first inlet and a first outlet. The second compressor is in fluid communication with the first compressor and includes a second inlet (e.g., a suction inlet), a third inlet (e.g., a vapor-injection inlet), a second compression mechanism, and a second outlet. The second and third inlets are fluidly coupled with the second compression mechanism. The second compression mechanism receives working fluid from the first compressor through the third inlet and discharges working fluid through the second outlet of the second compressor. The first and second compressors are in fluid communication with the first, second, and third heat exchangers.

    Abstract: A system includes a refrigerant compressor including an electric motor, a current sensor that measures current flow to the electric motor, a switching device configured to close and open to allow and prevent current flow to the electric motor, respectively, a maximum continuous current (MCC) device that includes a resistance corresponding to a maximum continuous current for the electric motor, and a motor protection module. The motor protection module communicates with the MCC device, the current sensor, and the switching device and determines a first MCC value for the electric motor as a function of the resistance of the MCC device. The motor protection module also selectively sets a predetermined MCC to the first MCC and controls the switching device based on a comparison of the current flow to the electric motor and the predetermined MCC.

    Abstract: A compressor is provided and may include a first compression mechanism, a first valve plate including a first port, and a first manifold including a first cylinder having a first piston disposed therein. The first piston may be movable between a first position opening the first port and a second position closing the first port. The compressor may additionally include a second compression mechanism, a second valve plate including a second port, and a second manifold including a second cylinder having a second piston disposed therein. The second piston may be movable between a first position opening the second port and a second position closing the second port. A valve assembly may move one of the first and second pistons into the first position while maintaining the other of the first and second pistons in the second position.

    Abstract: An apparatus is provided and may include a compression mechanism, a valve plate having a plurality of ports, a header, and a plurality of cylinders disposed within the header. A plurality of pistons may be respectively disposed in the plurality of cylinders and may be movable between a first position separated from the valve plate and permitting flow through the plurality of ports and into the compression mechanism and a second position engaging the valve plate and restricting flow through the plurality of ports and into the compression mechanism. A chamber may be disposed within each of the cylinders and may receive a pressurized fluid in a first mode to move the piston into the second position and may vent the pressurized fluid in a second mode to move the piston into the first position. One of the chambers may include a different diameter than the other of the chambers.

    Abstract: A reciprocating compressor may include a shell, a first cylinder, a plate, a second cylinder, and a piston. The first cylinder may be disposed within the shell and may include a first valve. The plate may be fixed relative to the first cylinder and may include a second valve. The second cylinder may be axially aligned with the first cylinder and may be moveable relative to the first cylinder between first and second positions. The piston may be disposed within the second cylinder and may include a third valve. The piston may reciprocate relative to the first and second cylinders. The piston and the plate may define a first compression chamber therebetween. The piston and the first cylinder may define a second compression chamber therebetween. A fluid-injection passage extending through the first cylinder selectively provides a working fluid from a source to the second compression chamber.
