Abstract: A rotary compressor system includes a compressor housing that includes a compressor motor that draws in fluid from a suction side. The fluid is compressed within a compression chamber and discharged through a discharge side. The compression chamber is disposed between the suction side and the discharge side. An overload-protection switch is electrically coupled in series with the compressor motor and is adapted to cut power to the compressor motor responsive to an overload event. A solenoid valve is fluidly coupled between the compression chamber and a location upstream of the suction side and is electrically coupled in series with the overload-protection switch. An interruption of electrical current to the compressor motor also interrupts electrical current to the solenoid valve, which opens the solenoid valve to equalize pressure between the suction side and the discharge side.

Abstract: A bypass line is described that is capable of equalizing pressure within an HVAC system. The bypass line can also cause less noise than other solutions. A bypass line under the present disclosure can comprise a line from a high pressure side to a low pressure side of an HVAC system. Valves and orifices can be disposed within the bypass line. The valves and orifices help to slow the speed of fluid from high pressure to low pressure locations, thus reducing noise during pressure equalization.

Abstract: A high side compressor system includes a compressor housing, motor, and a compression chamber. The compression chamber is disposed within the compressor housing. An accumulator is fluidly coupled to the compressor housing via a pressure-equalization tube. A pressure-equalization valve is disposed in the pressure-equalization tube. The pressure-equalization valve closes access to the pressure-equalization tube responsive to an electrical current being applied to the pressure-equalization valve. The pressure-equalization valve is electrically coupled to a compression mechanism such that interruption of electrical current to the compression mechanism interrupts electrical current to the pressure-equalization valve thereby opening the pressure-equalization valve.
