  • Methods and controllers for providing a surge map for the monitoring and control of chillers
    Patent number: 9097447
    Abstract: A controller for a chiller includes processing electronics configured to detect a plurality of surge events. The processing electronics create a surge map by calculating and plotting a point for each detected surge event in an at least two dimensional coordinate system. The surge map is displayed through the use of an electronic display system. The surge map describes at least three conditions of the chiller when the surge event was detected through the use of axis and non-axis representations. The processing electronics are further configured to control at least one setpoint for the chiller using the calculated surge map.

  • System and method for protecting turbine and compressor during shutdown
    Patent number: 6481978
    Abstract: A system and associated method for protecting during a shutdown a turbine having a turbine shaft and a compressor driven by the turbine shaft. The system include a first lubrication system, a second lubrication system, and a control system. The first lubrication system is configured to provide lubrication to the compressor. The second lubrication system is configured to provide lubrication to the turbine. The control system monitors the rotation of the turbine shaft in response to a shutdown request and causes the first and second lubrication systems to provide lubrication to the turbine and compressor until and after the turbine shaft stops rotating. The control system causes the first lubrication system to provide lubrication for a first predetermined period of time after the turbine shaft stops rotating. The control system causes the second lubrication system provides lubrication for a second predetermined period of time after the turbine shaft stops rotating.
