PROJECT STATEMENT

Dresser-Rand will be donating a single stage ESH reciprocating compressor for RIT use. The project objective is to safely install the compressor for educational and research activities. The focus of the project is on creating the installation plan, educational experiences, and instrumentation/data acquisition strategies.

INSTALLATION PLANStructural Integrity- Created and analyzed ANSYS Models of the room and skid based on materials and structure-Created plan to reinforce structure and mount the compressorVentilation- Calculated 250 cfm based on the black body analysis of the compressor, as well as inefficiency of motor and various thermal loads within the roomCooling System- Selected heat exchanger, pump, coolant tank, and screw heater based on thermal loadAcoustic- Measured sound intensity level to ensure cumulative noise level was not dangerous

USER INTERFACE

Sensors- Created list of sensors to facilitate future laboratories and research-Located sensors on compressor based on research and lab needs

Interface-Revised Labview® interface to supplement educational tools-Work with Dresser – Rand to account for fault detection in future projects

EDUCATIONAL TOOLSVibrations-Investigate damping provided by skid-Create a theoretical model using vibration analysis-Calculate max deflection on compressor based on data from accelerometers, measure deflection

Thermo fluids-Investigate the concepts of isentropic compression-Compute theoretical values and plot-Utilizing a high sample rate pressure transducer to generate real-time plots of pressure vs. volume-Compare theoretical vs. actual
