  • Method of operating an air conditioning system including reducing the energy consumed by the compressor crank case heaters
    Patent number: 9903627
    Abstract: A method of operating an air conditioning system includes cooling a selected space with the air conditioning system. The air conditioning system includes two or more compressors and two or more crank case heaters. Each crank case heater of the two or more crank case heaters is operably connected to a compressor of the two or more compressors. Operation of the two or more compressors is stopped, thus initiating operation of the two or more crank case heaters. The air conditioning system is switched to a conservation mode, including de-powering at least one compressor of the two or more compressors and a connected at least one crank case heater or the two or more crank case heaters.

  • COMPRESSOR CRANK CASE HEATER ENERGY REDUCTION
    Publication number: 20140124166
    Abstract: A method of operating an air conditioning system includes cooling a selected space with the air conditioning system. The air conditioning system includes two or more compressors and two or more crank case heaters. Each crank case heater of the two or more crank case heaters is associated with a compressor of the two or more compressors. Operation of the two or more compressors is stopped, thus initiating operation of the two or more crank case heaters. The air conditioning system is switched to a conservation mode, including de-powering at least one compressor of the two or more compressors and an associated at least one crank case heater or the two or more crank case heaters thereby reducing energy consumption of the two or more crank case heaters.

  • Lubrication system for roller transmission
    Patent number: 5035153
    Abstract: A lubrication system for a roller transmission having a sun roller, at least one row of planet rollers, and a surrounding ring roller. The lubrication system includes a fluid feed tube supplying lubricant to a distributing manifold. The manifold in turn supplies a plurality of cross feed tubes which direct fluid to the contacting surfaces between the adjacent rollers. The lubrication system also includes a lubrication conduit and connected cooling channels in the sun roller which feed lubricant to the interface between the sun roller and first row of planet rollers.
