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.

Abstract: A compressor includes a shell assembly, a compression mechanism and a suction fitting. The shell assembly defines a chamber. The compression mechanism is disposed within the chamber of the shell assembly and includes a suction inlet. The suction fitting is attached to the shell assembly and extends at least partially into the chamber of the shell assembly. The suction fitting defines first and second openings. The suction fitting directs working fluid through the first opening towards the compression mechanism and the suction fitting directs working fluid through the second opening away from the compression mechanism.

Abstract: A compressor that includes a shell assembly, a compression mechanism and a conduit. The shell assembly defines a chamber. The compression mechanism is disposed within the chamber of the shell assembly and includes a first scroll member and a second scroll member in meshing engagement with each other. The second scroll member includes an externally located slot and a suction inlet. The conduit includes a first end that defines an inlet opening and a second end that defines an outlet opening. The second end includes a connecting arm that has a first boss extending therefrom. The second end snaps into engagement with the second scroll member such that the first boss is received within the slot of the second scroll member.

Abstract: A climate-control system may include a first fluid circuit, a desiccant system, and a second fluid circuit. The first fluid circuit may include a desorber, an absorber, and an evaporator. A first fluid exits the desorber through a first outlet and flows through the evaporator and a first inlet of the absorber. A second fluid exits the desorber through a second outlet and may flow through a second inlet of the absorber. The desiccant system includes a conditioner and a regenerator. The conditioner includes a first desiccant flow path. The regenerator includes a second desiccant flow path in communication with the first desiccant flow path. The second fluid circuit circulates a third fluid that is fluidly isolated from the first and second fluids and desiccant in the desiccant system. The second fluid circuit may be in heat transfer relationships with the first fluid and the first desiccant flow path.

Abstract: Systems and methods for providing lubricant from a first compressor to a second compressor are provided. A control module receives a start command for a climate-control system having the first and second compressors, allows lubricant from the first compressor to flow into an inlet of the second compressor, turns the second compressor to an ON-mode, and prevents lubricant from the first compressor from flowing into the inlet of the second compressor after the second compressor has been in the ON-mode for a predetermined time period.

Abstract: Systems and methods for purging lubricant from a first compressor to a second compressor are provided. A control module receives a lubricant purge command, shuts the second compressor to an OFF-mode while the first compressor remains in the ON-mode, restricts working fluid from an outlet of the second compressor from flowing into the first compressor and allows compressed working fluid discharged from an outlet of the first compressor to flow into the inlet of the second compressor such that lubricant in the second compressor flows into the first compressor.

Abstract: A climate-control system includes a first compressor and a second compressor. The first compressor includes a first inlet and a first outlet. The second compressor is in fluid communication with the first compressor and includes second and third inlets, a second compression mechanism and a second outlet. The second and third inlets are fluidly coupled to 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.

Abstract: An indoor air quality (IAQ) system for a building includes an IAQ sensor that is located within the building and that is configured to measure an IAQ parameter. The IAQ parameter is one of: an amount of particulate of at least a predetermined size present in air; an amount of volatile organic compounds (VOCs) present in air; and an amount of carbon dioxide present in air. A mitigation module is configured to: selectively turn on a mitigation device based on a comparison of the IAQ parameter with a first ON threshold and a second ON threshold; and selectively turn off the mitigation device based on a comparison of the IAQ parameter with an OFF threshold. A clean module is configured to determine a clean value for the IAQ parameter. A thresholds module is configured to, based on the clean value, determine the first ON threshold and the OFF threshold.

Abstract: Systems and methods are provided and include a charging circuit, a converter network, and a voltage regulator. The voltage regulator couples the charging circuit to the converter network. When the system is in the charging mode, the charging circuit is configured to receive a serial communication signal that charges the charging circuit. When the system is in the communication mode, the voltage regulator is configured to limit an amount of voltage discharge from the charging circuit, and the converter network is configured to receive the serial communication signal and convert the serial communication signal to a second signal having a second type. The second type has a different communication protocol than the serial communication signal. When the system is in the communication mode, the converter network is configured to transmit the second signal to a remote device.
