The first working fluid circuit includes a first compressor and a first heat exchanger in fluid communication with the first compressor. The second working fluid circuit includes a second compressor and a second heat exchanger in fluid communication with the second compressor. The storage tank contains a phase-change material. The first working fluid circuit and the second working fluid circuit are thermally coupled with the phase-change material contained in the storage tank.

Abstract: A compressor includes a shell assembly, a muffler plate and a compression mechanism. The shell assembly has a suction chamber and a discharge chamber. The muffler plate is disposed within the shell assembly and separates the suction chamber from the discharge chamber. The muffler plate includes a hub having a circumferentially extending inner portion and a circumferentially extending intermediate portion. The circumferentially extending inner portion defines a discharge passage extending therethrough. The circumferentially extending intermediate portion has a slot formed in a surface thereof. The slot extends at least partially around the circumferentially extending intermediate portion. The compression mechanism is disposed within the suction chamber and provides working fluid to the discharge chamber via the discharge passage of muffler plate.

Abstract: A compressor system includes a compressor housing and a driveshaft rotatably supported within the compressor housing. The compressor system further includes an impeller that imparts kinetic energy to incoming refrigerant gas upon rotation of the driveshaft, a thrust disk coupled to the driveshaft, and a bearing assembly mounted to the compressor housing. The impeller includes an impeller bore having an inner surface, and the thrust disk includes an outer disk and a hub. The bearing assembly rotatably supports the outer disk of the thrust disk. The hub is disposed within the impeller bore, and includes a hub outer surface in contact with the inner surface of the impeller bore. A first contact force between the hub outer surface and the inner surface of the impeller bore increases with increased rotational speed of the driveshaft.

Abstract: A system includes a dynamic compressor to compress a working fluid and a controller. The controller is connected to the dynamic compressor and includes a processor and a memory. The memory stores a map of predetermined operating points of the dynamic compressor, each predetermined operating point including a mass flow of the compressor at that predetermined operating point. The memory stores instructions that program the processor to operate the dynamic compressor to compress the working fluid and determine a current operating point of the compressor. The instructions program the processor to calculate the mass flow for the current operating point from the map of the plurality of predetermined operating points. The instructions further program the processor to continue to operate the dynamic compressor to compress the working fluid based at least in part on the calculated mass flow for the current operating point.

Abstract: A light-weight, high-strength insulating compressor component formed via additive manufacturing is provided. The component may have at least one interior region comprising a lattice structure that comprises a plurality of repeating cells. A solid surface is disposed over the lattice structure. The interior region comprising the lattice structure minimizes or reduces transmission of at least one of thermal energy, sound, or vibrational energy through the component. Methods of making such compressor components via additive manufacturing processes are also provided.

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.
