Abstract: A system includes a dynamic compressor, a variable frequency drive (VFD), and a controller. The dynamic compressor includes a motor having a driveshaft rotatably supported within the dynamic compressor, and a compression mechanism connected to the driveshaft and operable to compress a working fluid upon rotation of the driveshaft. The VFD includes a sensor configured to sense a current provided to the motor. The controller is connected to the motor and includes a processor and a memory. The memory stores instructions that program the processor to operate the motor using the VFD to compress the working fluid, receive signals representing the current from the VFD to the motor, and determine when a surge event has occurred based at least in part on the received signals representing the current from the VFD to the motor.

Abstract: A refrigerant measurement adjustment system includes: a refrigerant sensor for a building and configured to measure an amount of refrigerant present in air outside of a refrigeration system of the building; and an adjustment module configured to: adjust the amount of refrigerant measured based on an adjustment to produce an adjusted amount; and determine the adjustment based on at least one of: an air temperature; an air pressure; a relative humidity of air; a mode of operation of the refrigeration system; a change in the measurements of the refrigerant sensor over time; and whether a blower that blows air across a heat exchanger of the refrigeration system located within the building is on.

Abstract: A compressor includes a shell, a compression mechanism and a fitting. The shell includes an opening and defines a chamber. The compression mechanism is disposed within the chamber of the shell. The fitting is attached to the shell at the opening. Working fluid flowing through the fitting flows to the compression mechanism. The opening is partially defined by a first edge and a second edge. The first edge includes a first planar surface and the second edge includes a second planar surface that faces the first planar surface. A first portion of the fitting extends at least partially into the opening and a second portion of the fitting abuts against the first and second edges.

Abstract: A compressor may include a compressor shell, a motor, a compression mechanism, and an assembly that houses an electronic component. The electronic component may control operation of the compressor and/or diagnose compressor faults. The assembly may include a shell, an electronic component, a fan, and an airflow deflector. The shell member may define an enclosure having an internal cavity. The fan and the electronic component may be disposed within the internal cavity. The airflow deflector may include a base portion, a first leg, and a second leg. The first and second legs may be spaced apart from each other and extend from the base portion. The fan may force air against the base portion. A first portion of the air may flow from the base portion along the first leg. A second portion of the air may flow from the base portion along the second leg.

Abstract: A valve plate assembly for a compressor according to the principles of the present disclosure includes a valve plate and a suction valve retainer. The valve plate is configured to separate suction-pressure working fluid entering a cylinder of the compressor from discharge-pressure working fluid exiting the cylinder of the compressor. The valve plate defines a discharge valve seat. The suction valve retainer is configured to retain a suction valve within a suction valve seat disposed about a central longitudinal axis of the cylinder.

Abstract: A compressor may include a shell assembly, orbiting and non-orbiting scrolls, a bearing housing, a bushing, a damper, and a fastener. The bearing housing includes a first aperture. The bushing may include an axial end abutting the bearing housing. The bushing may extend through a second aperture of the non-orbiting scroll. The bushing may include a third aperture. The damper may be received in a pocket that may be defined by and disposed radially between an outer diametrical surface of the bushing and an inner diametrical surface of the non-orbiting scroll. The damper may be at least partially disposed within the second aperture and may encircle the second portion of the bushing. The fastener may include a shaft portion and a flange portion. The shaft portion may extend through the third aperture and into the first aperture. The flange portion may contact a first axial end of the damper.

Abstract: A compressor may include first and second scroll members, first and second bearing housings, and a motor assembly. The first scroll member includes a first end plate and a first spiral wrap extending from the first end plate. The second scroll member includes a second end plate and a second spiral wrap extending from the second end plate and intermeshed with the first spiral wrap to define compression pockets therebetween. The first bearing housing supports the first scroll member for rotation about a first rotational axis. The second bearing housing may support the second scroll member for rotation about a second rotational axis that is parallel to and offset from the first rotational axis. The motor assembly may be disposed axially between the first and second bearing housings and may include a rotor attached to the first scroll member. The rotor may surround the first and second end plates.

Abstract: A control system for a mitigation device includes a processor and a computer-readable medium that includes instructions executable by the processor. The instructions include monitoring a first measured particulate matter (PM) level of a conditioned space. The first measured PM level includes PM having a first range of sizes. The instructions further include monitoring a second measured PM level of the conditioned space. The second measured PM level includes PM having a second range of sizes. The first and second ranges are different but overlapping. The instructions also include asserting, in response to the first measured PM level being greater than a first predetermined threshold, an activation signal. The activation signal forces operation of a fan of the mitigation device. The instructions include asserting, in response to the second measured PM level being greater than a predetermined percentage of the first measured PM level, the activation signal.

Abstract: A compressor may include a shell assembly, a compression mechanism, a driveshaft, a first bearing, a second bearing, a third bearing, and a surface supporting the third bearing. The compression mechanism may include first and second compression members. The driveshaft may be coupled to the first compression member to rotate the first compression member relative to the second compression member. The first bearing may support the driveshaft for rotation about a first axis. The second bearing may support the driveshaft for rotation about the first axis. The third bearing defines a second axis. The third bearing may support the second compression member for rotation relative to the first compression member. The surface may support the third bearing such that the third bearing is able to roll along the surface to move the second compression member and the second axis in a radial direction relative to the first compression member.
