  • Patent number: 8769982
    Abstract: A refrigeration system can use a flash tank to separate vapor refrigerant from liquid refrigerant. The refrigeration system can include a liquid-refrigerant injection system that can inject liquid refrigerant into an intermediate-pressure location of the compressor. The injected liquid refrigerant can absorb the heat of compression during the compression process. The refrigeration system can include an economizer system that injects a refrigerant vapor into an intermediate-pressure location of the compressor in conjunction with the injection of the cooling liquid. The refrigeration system can incorporate a cooling-liquid injection system that can inject a cooling liquid into an intermediate-pressure location of the compressor.

  • Patent number: 8393882
    Abstract: A scroll compressor is provided and may include an orbiting scroll member having an orbiting end plate and an orbiting spiral wrap extending from the orbiting end plate. The scroll compressor may also include a non-orbiting scroll member having a non-orbiting end plate and a non-orbiting spiral wrap extending from the non-orbiting end plate and intermeshed with the orbiting spiral wrap. The scroll compressor may further include a drive member for causing the orbiting scroll member to orbit relative to the non-orbiting scroll member and a discharge slot formed by one of the orbiting scroll member and the non-orbiting scroll member. A discharge valve may be rotatable with the drive member and may operate between a closed state preventing fluid communication between the pockets and the discharge slot and an open state permitting fluid communication between the pockets and the discharge slot.

  • Patent number: 8181478
    Abstract: A refrigeration system can incorporate a liquid-injection system that can provide a cooling liquid to an intermediate-pressure location of the compressor. The cooling liquid can absorb the heat of compression during the compression of the refrigerant flowing therethrough. The refrigeration system can include an economizer circuit that injects a refrigerant vapor into an intermediate-pressure location of the compressor in conjunction with the injection of the cooling liquid. The incorporation of the vapor injection in conjunction with the cooling-liquid injection can advantageously increase the cooling capacity and/or efficiency of the refrigeration system and the performance of the compressor.

  • Patent number: 7997883
    Abstract: A scroll compressor may incorporate controlled bending of a scroll member to compensate for axial deformations that can occur between the scroll members. The controlled bending may be through the use of fluid pressure in a sealed chamber that communicates with a surface of the scroll member opposite the intermeshing wraps. Fluid passageways can extend through the scroll member between the sealed chamber and the intermeshing wraps. The controlled bending can increase the uniformity of the contact between the scroll members and improve the efficiency of the compressing operation.

  • Patent number: 7896629
    Abstract: A scroll compressor includes an orbiting scroll member having an orbiting end plate defining a discharge port and an orbiting spiral wrap extending from the orbiting end plate. The compressor also includes a non-orbiting scroll member having a non-orbiting end plate and a non-orbiting spiral wrap extending from the non-orbiting end plate. The non-orbiting spiral wrap is intermeshed with the orbiting spiral wrap. Furthermore, a bearing housing extends from the non-orbiting end plate opposite from the non-orbiting spiral wrap, and a drive member causes the orbiting scroll member to orbit relative to the non-orbiting scroll member whereby said spiral wraps create pockets of progressively changing volume between a suction pressure zone and a discharge pressure zone. The drive member extends through the bearing housing, the non-orbiting scroll member and the orbiting scroll member. Also, the scroll compressor includes a discharge valve for controlling fluid flow through the discharge port.

  • Patent number: 7841845
    Abstract: A compressor assembly includes a planetary gear train located between an input shaft from the power unit and a drive shaft of the compressor. The planetary gear train is switchable between a high speed and a low speed condition. In the high speed condition, power is provided to the planetary gears, the ring gear is locked and output to the drive shaft is through the sun gear. In the low speed condition, a one-way clutch between the input shaft and the output shaft provides a one-to-one driving ratio.

  • Patent number: 7837452
    Abstract: A scroll compressor an orbiting scroll member including a second end plate, a second wrap extending from the second end plate and meshingly engaged with the first wrap to form a suction pocket in fluid communication with a suction pressure region of the compressor, intermediate compression pockets, and a discharge pocket in fluid communication with the discharge passage. An auxiliary passage is in fluid communication with one of the intermediate compression pockets to provide pressurized fluid to the chamber to deflect the first end plate and the first wrap axially toward the orbiting scroll member.
