Abstract: A compressor includes a shell, a first compression member, a bearing housing and a second compression member. The first compression member is rotatable relative to the shell about a first axis. The bearing housing is coupled to the first compression member and rotatable relative to the shell about the first axis. The bearing housing includes a first pin that extends therefrom. The second compression member is rotatable relative to the shell about a second axis. The second compression member includes a base plate and an arcuate-shaped first pin pocket. The first pin pocket is formed in the base plate and receives the first pin. The first compression member is moveable between a first position in which the first pin is engaged with a surface of the first pin pocket and a second position in which the first pin is disengaged from the surface of the first pin pocket.

Abstract: An HVAC system includes an unloading device, a centrifugal compressor, a gas foil bearing, a VFD and a controller. The controller is programmed to start the centrifugal compressor from a stopped condition by operating the unloading device to remove a load from the centrifugal compressor, accelerating the motor to a first speed above a liftoff speed of the gas foil bearing and below an operating speed of the centrifugal compressor, running the motor for a period of time, operating the unloading device to apply the load to the centrifugal compressor, and accelerating the motor to the operating speed.

Abstract: A heating, ventilation, and air conditioning (HVAC) system includes a hot water sub-system including a first heat exchanger and a condenser, a cold water sub-system including a second heat exchanger and an evaporator, and a refrigerant sub-system for transferring heat from the cold water sub-system to the hot water sub-system. The first and second heat exchangers transfer moisture and heat between a liquid desiccant and air. The refrigerant sub-system includes a compressor, the condenser, an expansion valve, the evaporator, and a refrigerant-air heat exchanger. The condenser transfers heat from compressed refrigerant to the hot water sub-system. The evaporator transfers heat from the cold water sub-system to uncompressed refrigerant. The refrigerant-air heat exchanger transfers heat from a portion of the compressed refrigerant to air in a first operating mode, and transfers heat from the air to a portion of the uncompressed refrigerant in a second operating mode.

Abstract: A system for monitoring health of refrigerated storage containers includes an instantaneous health module configured to determine instantaneous health values for a refrigerated storage container based on parameters measured by sensors of a refrigeration system of the refrigerated storage container during a trip of the refrigerated storage container. A statistics module is configured to, after completion of the trip of the refrigerated storage container, determine statistical values based on the instantaneous health values determined for the trip. A health module is configured to determine an overall health value for the refrigerated storage container at the completion of the trip based on the statistical values and to store the overall health value for the refrigerated storage container in memory in association with a unique identifier of the refrigerated storage container.

Abstract: A compressor may include first and second scroll members, a driveshaft, first and second bearings, and first and second Oldham couplings. The scroll members define compression pockets. The first bearing may define a first rotational axis about which the first scroll member rotates. The second bearing may support the second scroll member for rotation about a second rotational axis that is offset from the first rotational axis. The first Oldham coupling may include a first body and a plurality of first keys extending from the first body. The first keys may engage slots formed in the second scroll member. The second Oldham coupling is separate and distinct from the first Oldham coupling. The second Oldham coupling may include a second body and a plurality of second keys extending from the second body. The second keys may engage slots formed in a surface that rotates about the first rotational axis.

Abstract: A climate-control system may include a compressor, a condenser, an evaporator, a first sensor, a second sensor, a third sensor, and a control module. The compressor may include a motor and a compression mechanism. The condenser receives compressed working fluid from the compressor. The evaporator is in fluid communication with the compressor and disposed downstream of the condenser and upstream of the compressor. The first sensor may detect an electrical operating parameter of the motor. The second sensor may detect a discharge temperature of working fluid discharged by the compression mechanism. The third sensor may detect a suction temperature of working fluid between the evaporator and the compression mechanism. The control module is in communication with the first, second and third sensors and may determine whether a refrigerant floodback condition is occurring in the compressor based on data received from the first, second and third sensors.

Abstract: A compressor may include first and second scrolls, an axial biasing chamber, and a modulation control valve. The second scroll includes an outer port and an inner port. The outer and inner ports may be open to respective intermediate-pressure compression pockets. The modulation control valve may be in fluid communication with the inner port, the outer port, and the axial biasing chamber. Movement of the modulation control valve into a first position switches the compressor into a reduced-capacity mode and allows fluid communication between the inner port and the axial biasing chamber while preventing fluid communication between the outer port and the axial biasing chamber. Movement of the modulation control valve into a second position switches the compressor into a full-capacity mode and allows fluid communication between the outer port and the axial biasing chamber while preventing fluid communication between the inner port and the axial biasing chamber.

Abstract: A compressor includes first and second scroll members and a bearing housing. The first scroll member includes a first end plate and a first scroll wrap. The second scroll member includes a second end plate that has a first surface, a second surface, and an oil passage. The first surface has a second scroll wrap meshingly engaging the first scroll wrap. The second surface includes an oil slot. The oil passage is in fluid communication with the oil slot. The bearing housing cooperates with the second scroll member to define an interior volume. The second scroll member is movable between a first position in which lubricant in the interior volume is allowed to flow into the oil passage via the oil slot, and a second position in which working fluid in the chamber is allowed to flow into the oil passage via the oil slot.

Abstract: A climate-control system may include a first compressor, a second compressor, a suction manifold, and a flow restrictor. The first and second compressors each include a shell and a compression mechanism. The shells define suction chambers from which the compression mechanisms draw working fluid. The shells include suction inlet fittings through which working fluid is drawn into the suction chambers. The suction inlet fittings are fluidly connected to the suction manifold. The suction manifold provides suction-pressure working fluid to the suction inlet fittings of the first and second compressors. The flow restrictor may be at least partially disposed within the suction manifold.

Abstract: A magnetic HVIL system for a drive in a transport application includes a Hall effect sensor within at least one housing of the drive that includes terminals and a removable cover. The removable cover includes a magnet having a magnetic field that is detectable by the Hall effect sensor when the removable cover is installed on the housing. The magnetic field of the magnet is not detectable by the Hall effect sensor when the removable cover is removed from the housing. The magnet HVIL system is configured to be operable to enable active operation of the drive when the Hall effect sensor detects the magnetic field of the magnet and is in a closed circuit condition and disable operation of the drive when the Hall effect sensor does not detect the magnetic field of the magnet and is in an open circuit condition.
