  • Patent number: 8904814
    Abstract: A system and method for determining a fault condition in a compressor is provided. The current of a motor drive powering the compressor and the outdoor ambient temperature are measured and used to determine if a fault condition or a potential fault condition is present in the compressor. If a fault condition is determined to be present, the compressor can be shutdown to avoid damage to the compressor. If a potential fault condition is determined, remedial action can be taken to attempt to prevent the fault condition from occurring and shutting down the compressor.

  • Publication number: 20140212307
    Abstract: The compressor fittings, both suction and discharge, of a compressor can have braze rings positioned inside of the fittings as part of the compressor assembly. The braze ring can then be used by an installer to connect the compressor to corresponding suction and discharge lines of a system. The installer can insert the system tube or connection into the fitting and apply a torch until braze material can be seen exiting the joint around the system tube, which indicates the tube has been connected.

  • Publication number: 20140212311
    Abstract: A compressor can have one or more of a suction fitting with integral louvers and a screen, a motor cap with a plurality of holes in the top surface of the motor cap to permit refrigerant to enter a suction plenum, a filter positioned over the plurality of holes in the motor cap, a filter for the cage bearing and a braze ring installed in one or more of the compressor fittings.

  • Publication number: 20140212310
    Abstract: A suction fitting for a compressor can include screens, filters, and direction control louvers to both filter out particulates and direct higher mass liquid refrigerant downward away from the inlet to the compression chamber. Alternatively, a mesh filter can be place over the opening(s) to the suction plenum to prevent debris and contaminants from entering the suction plenum.

  • Publication number: 20140212309
    Abstract: A motor cap has a plurality of holes in the top of the cap for the entry of refrigerant into the suction plenum. The holes are sized and located to create a tortuous path for a stream of refrigerant to enter the compression chamber. The refrigerant stream is broken into multiple streams and any liquid refrigerant is encouraged to flash to vapor. Any oil that is brought from the sump at startup by boiling liquid refrigerant is likewise encouraged to remain on the motor cap and drain back to the sump while the liquid refrigerant flashes to vapor.

  • Patent number: 8790089
    Abstract: A system and method is provided for controlling the speed of the compressor to ensure adequate lubrication oil is provided to the components of the compressor. During operation of a capacity control program for the compressor, a preselected operating parameter of the compressor or motor drive is measured. The measured preselected operating parameter is compared to a preselected range for the operating parameter. If the measured preselected operating parameter is not within the preselected range, the output frequency of the capacity control program can be increased to provide proper lubrication for the components of the compressor.

  • Patent number: 8672642
    Abstract: A system and method for starting a compressor is provided. An amount of liquid refrigerant that is located in an oil sump of the compressor is determined. Using the determined amount of liquid refrigerant, a starting algorithm for the compressor is selected. The selected starting algorithm is configured to remove the determined amount of liquid refrigerant from the oil sump before the compressor reaches a preselected operating speed. The selected starting algorithm is then executed to start the compressor.

  • Publication number: 20080034772
    Abstract: An automatic self-modulation capacity compressor for an HVAC&R system is disclosed. The system includes a housing, a compressor, a motor, and a pressure sensitive control valve. The HVAC&R system further comprises an expander and a condenser. In the open position, the control valve permits a portion of the pressurized gasses from the compressor to escape, creating a partial capacity compressor within the system. Once a predetermined set point pressure differential is met, the control valve moves to the closed position, where all of the pressurized gasses within the compressor are provided to the system, thereby creating a full capacity compressor. Once the compressor is operating in full capacity, the compressor remains in full capacity mode until the demands of the system are met and the compressor shuts down. Upon restart, the compressor operates in partial capacity until the predetermined set point pressure is met once again and the compressor begins operating in full capacity.

  • Patent number: 5329666
    Abstract: A hand-held corded vacuum cleaner having a housing with a motor compartment containing a motor mounted on partitions defining inlet, cooling and outlet chambers for efficient motor cooling by air which enters inlet and exits outlet vents in the inlet and outlet chambers, respectively. A dirt channel extends from a fan chamber having a fan mounted by being swaged on a motor shaft. A nozzle chamber is disposed at one end of the housing and a bag assembly is removably detached from the rear of the housing by means of a collar having a side hole through which a detent extends and which may be depressed to remove the bag assembly. The nozzle is in communication with the fan chamber and the fan pushes dirt through a dirt channel over the motor compartment into the bag of the bag assembly. The motor shaft has a pulley at the end thereof which is connected to a brush which is releasably retained in the nozzle compartment. A belt extends around the brush and the pulley.
