  • Enhanced manual start/stop sequencing controls for a stream turbine powered chiller unit
    Patent number: 7421853
    Abstract: A control system and method for interactive startup and shutdown of a steam turbine driven chiller unit is provided. The chiller unit includes an integrated central control panel to control operation of both the steam turbine system and the refrigerant system. The central control panel has startup control system to assist an operator manually start the steam turbine system and the refrigerant system and a shutdown control system to assist an operator manually shutdown the steam system and the refrigerant system. Both the startup control system and the shutdown control system include logic for performing necessary protective actions and for notifying an operator when to perform required actions.

  • Automatic start/stop sequencing controls for a steam turbine powered chiller unit
    Patent number: 7421854
    Abstract: A control system and method are provided for the automatic startup and shutdown of a steam turbine driven chiller unit. The chiller unit includes an integrated central control panel to control operation of both the steam turbine system and the refrigerant system. The central control panel has a startup control system to automatically start the steam turbine driven chiller unit while performing necessary protective actions and a shutdown control system to automatically stop the steam turbine driven chiller unit while performing necessary protective actions.

  • Integrated adaptive capacity control for a steam turbine powered chiller unit
    Patent number: 7328587
    Abstract: A control system for a steam turbine driven chiller unit is provided. The control system automatically utilizes the full range of the governor, compressor pre-rotation vanes, and hot gas bypass valve capabilities to control the capacity of the chiller and provide anti-surge and override control functions to prevent undesirable operational ranges while maintaining maximum efficiency of operation.

  • Suction connection for dual centrifugal compressor refrigeration systems
    Patent number: 6910349
    Abstract: A dual centrifugal compressor refrigeration system has one evaporator for both compressors. The evaporator provides the centrifugal compressors with refrigerant vapor through separate suction connections for each compressor. Each suction connection has a protrusion that extends into the evaporator vessel to disturb the axial flow of refrigerant vapor in the evaporator vessel. The disturbance of the axial flow of refrigerant vapor in the evaporator vessel permits a surging compressor to draw refrigerant vapor in order to recover from the surge condition.
