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.

Abstract: A method of manufacturing an impeller includes attaching blades to a hub. The impeller includes the blades, the hub, and a shroud. The blades each include a tip, and the shroud includes an inner surface and at least one ring extending from the inner surface. The method also includes applying a brazing compound to the tips of the blades and to the inner surface of the shroud. The method includes inserting the blades and the hub into the shroud such that the tips of the blades press against the rings. The rings and the tips of the blades form an interference fit between the rings and the tips of the blades that maintains a consistent gap between the shroud and the blades during manufacture of the impeller. A compressor including the impeller is also disclosed.

Abstract: A cylinder head assembly for a compressor according to the present disclosure includes a valve plate and a cylinder head. The valve plate is configured to mount to a mounting surface of the compressor. The valve plate includes a suction chamber, a suction passage providing fluid communication between the suction chamber and a cylinder of the compressor, a suction valve seat through which the suction passage extends, and a discharge passage extending through the valve plate and defined by a discharge valve seat. The cylinder head at least partially covers the valve plate and defines a discharge chamber that is in selective fluid communication with the cylinder via the discharge passage. The cylinder head and the valve plate are formed together as a unitary body.

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 desired OFF period module is configured to determine a desired OFF period for a plurality of switches of a PFC circuit based on an input voltage and an output voltage. A blanking timer module is configured to output a blanking signal, set the blanking signal to a first state when a countdown timer is greater than zero, and set the blanking signal to a second state when the countdown timer reaches zero. A switching control module is configured to: transition a first switch of the plurality of switches from an ON state to an OFF state in response to (i) a measured current through an inductor of the PFC circuit being greater than a demanded current through the inductor and (ii) the blanking signal being in the second state; and maintain the first switch in the OFF state for the desired OFF period after the transition.
