Abstract

A climate-control system may include first and second compressors and a suction manifold. The first compressor includes a first shell, a first compression mechanism, and a first suction inlet through which working fluid is drawn into the first compressor. The second compressor includes a second shell, a second compression mechanism, and a second suction inlet through which working fluid is drawn into the second compressor. The suction manifold includes first and second arms. The first arm provides working fluid to the first suction inlet. The second arm provides working fluid to the second suction inlet. The second arm includes a first suction pipe, a second suction pipe, and a suction valve. The suction valve is movable between a first position in which working fluid is allowed to flow through the first suction pipe and a second position in which working fluid is allowed to flow through the second suction pipe.

Abstract

A compressor may include a shell assembly, first and second scrolls, a floating seal assembly, a modulation-valve ring, and a modulation-control-valve assembly. The shell assembly may define a suction-pressure region. The first scroll may include a discharge passage, a modulation port, and a biasing passage. The modulation-valve ring may cooperate with the floating seal assembly and the first scroll to define an axial-biasing chamber in fluid communication with the biasing passage. The modulation-valve ring may be axially displaceable between a closed position to close the modulation port and an open position to open the modulation port. The modulation-control-valve assembly may be mounted to the modulation-valve ring and may be movable between a first position corresponding to the closed position and a second position corresponding to the open position.

Abstract

In other features, a refrigeration system is provided and includes a compressor motor, an inverter, a converter and a control module. The inverter is configured to convert a direct current (DC) bus voltage to an alternating current (AC) voltage and supply the AC voltage to the compressor motor. The converter is configured to convert a DC input voltage to the DC bus voltage. The control module is configured to obtain a parameter and in response to the parameter exceeding a predetermined threshold, reduce the DC bus voltage and at least one of (i) reduce a switching frequency, (ii) increase an amount of negative d-axis current of the compressor motor, or (iii) reduce a speed of the compressor motor.

Compressor having a terminal cluster block with locking end fittings

Abstract

A connector block assembly has a connector block and a plurality of end fittings which are attached to at least one wire. Each end fitting is secured to the connector block by being inserted into the connector block and then being rotated to trap the end fitting within the connector pin. Once assembled onto a conductor pin, the conductor pin prohibits rotation of the end fitting with respect to the connector block and thus the disassembly of the end fitting from the connector block.

Abstract

A compressor includes a normally open discharge valve assembly for controlling compressed refrigerant flow from the discharge chamber through the compression members. This controlling of flow results in an increased performance for the compressor by reducing recompression volume and the elimination of reverse rotation at shut down. The discharge valve assembly includes a valve seat, a valve plate and a valve stop secured within a recess formed within the compressor with a wave ring retainer. The valve stop and the valve seat include a contoured surface that is engaged by the valve plate when it opens and closes. The contoured surface controls the movement of the valve plate.
