  • Energy recovery system and method for a refrigerated dehumidification process
    Patent number: 8006503
    Abstract: A gas compression system includes a flow of compressed gas, a separator positioned to receive the flow of compressed gas and discharge a second flow of compressed gas and a flow of condensate, and a flow of compressed refrigerant. A heat exchanger is positioned to receive the flow of condensate and the flow of compressed refrigerant. The heat exchanger is arranged such that the flow of condensate cools the flow of refrigerant.
    Type: Grant

  • Variable speed compressor cooling system
    Publication number: 20040244393
    Abstract: A compressor assembly including one or more compressors associated with compressor drive means. A cooling system is positioned downstream from the compressor and includes at least one air circulator, for example, a fan or a blower, and at least one heat exchanger. The air circulator is associated with a circulator variable speed drive, the speed of which can be adjusted independent of the compressor drive means. One or more sensors are associated with the circulator drive. The sensors sense desired variables and the speed of the circulator drive is adjustable in response to real-time sensed conditions.
