Abstract: A scroll compressor includes a housing, a non-orbiting scroll member including a first spiral wrap, and an orbiting scroll member including a second spiral wrap. The first and second spiral wraps are interleaved to define at least one moving fluid pocket that decreases in size as it moves from a radially outer position to a radially inner position. A vapor-injection system may include a shell fitting in fluid communication with a fluid passageway of the non-orbiting scroll member via a vapor injection tube. The vapor injection tube may be fixed for movement with the non-orbiting scroll member for communicating vapor into the moving fluid pockets.

Abstract: A compressor includes a compression mechanism, a driveshaft, and a motor. The compression mechanism is configured to compress a fluid to a discharge pressure. The motor is configured to rotate the driveshaft. The driveshaft is engaged with the compression mechanism and is fixed to rotate with at least a portion of the compression mechanism. The driveshaft includes a longitudinal aperture configured to receive the fluid at a suction pressure, and includes a flange that receives at least a portion of the compression mechanism. The flange and the compression mechanism define a fluid passage therebetween. The fluid at suction pressure is received within the fluid passage from the longitudinal aperture in the driveshaft.

Abstract: A refrigeration system includes a main fluid loop and a secondary fluid loop. The main fluid loop includes a compressor and a heat exchanger that circulate a first working fluid. The secondary fluid loop circulates a second working fluid. The secondary fluid loop is in thermal communication with the main fluid loop at the heat exchanger. The secondary fluid loop includes a pump, a thermal energy storage, and a coil fluid line. The secondary fluid loop includes a multi-position valve configured to move between positions that selectively fluidly connect the heat exchanger, the pump, the thermal energy storage, and the coil fluid line.

Abstract: A method for determining a mass flow of a dynamic compressor that does not include a mass flow sensor while the compressor is operating to compress a working fluid includes determining, by a processor, a current operating point of the compressor. If the current operating point is the same as one in a map of a plurality of predetermined operating points stored in a memory, the mass flow of that predetermined operating point is retrieved as the mass flow of the current operating point. Otherwise, the processor calculates the mass flow at the current operating point from the mass flows of a subset of the predetermined operating points nearest the current operating point. The dynamic compressor continues to operate to compress the working fluid based at least in part on the calculated mass flow rate for the current operating point.

Abstract: A heat-pump system may include an outdoor heat exchanger, an expansion device, an indoor heat exchanger, a compressor, and a multiway valve. The expansion device is in fluid communication with the outdoor heat exchanger. The indoor heat exchanger is in fluid communication with the expansion device. The compressor circulates working fluid through the indoor and outdoor heat exchangers. The multiway valve may be movable between a first position corresponding to a cooling mode of the heat-pump system and a second position corresponding to a heating mode of the heat-pump system. The working fluid flows in the same direction through the outdoor heat exchanger in the cooling mode and in the heating mode, and the working fluid flows in the same direction through the indoor heat exchanger in the cooling mode and in the heating mode.

Abstract: A cooling system for a compressor includes a coolant supply line, a coolant return line, a temperature sensor connected to the coolant return line to detect at least one of a temperature of the coolant return line and a temperature of coolant within the coolant return line, and a controller. The coolant supply line includes a coolant control valve, and is connectable to a housing of the compressor to deliver coolant to at least one of a plurality of coolant flow channels defined therein. The coolant return line is connectable to the compressor housing to receive coolant from the coolant flow channels and return coolant to a low-pressure side of the compressor. The controller is configured to control the coolant control valve based on the temperature detected by the temperature sensor to control the supply of coolant through the coolant supply line.

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 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 climate-control system includes a first working-fluid circuit, a second working-fluid circuit and a first heat exchanger. The first working-fluid circuit includes a first compressor, a second heat exchanger and a first pump. The second heat exchanger is in fluid communication with the first compressor. The first pump receives a first working fluid from the second heat exchanger and circulates the first working fluid through the first working-fluid circuit. The second working-fluid circuit is fluidly isolated from the first working-fluid circuit and includes a second pump and a fourth heat exchanger. The second pump is in fluid communication with the fourth heat exchanger. The first heat exchanger is thermally coupled with the first working-fluid circuit and the second working-fluid circuit.
