REFRIGERATION COMPRESSOR PERFORMANCE USING CALORIMETER AND FLOWRATER TECHNIQUES.

Author(s) : DUGGAN M. G., HUNDY G. F., LAWSON S.

Summary

INA LABORATORY, THE EQUIPMENT WHICH BEST SIMULATES A REAL SYSTEM IS A CALORIMETER. FOR LARGE COMPRESSORS IT IS NOT PRACTICAL TO USE CALORIMETERS SO, FLOWRATER DEVICES SUCH AS ORIFICE PLATES, VENTURI OR MASS FLOW METERS ARE USED. THE AUTHORS IDENTIFY THE DIFFERENCES WHICH HAVE BEEN FOUND. IN THE EVENT OF THERE BEING ANY REFRIGERANT PROPERTY ERRORS, THEY WILL CANCEL OUT IN THE CALORIMETER METHOD BECAUSE 2 ENTHALPY DIFFERENCES ARE USED AS A RATIO. IN THE FLOWRATER METHOD ANY REFRIGERANT PROPERTY ERRORS HAVE A DIRECT EFFECT AS SPECIFIC VOLUME IN THE MASS FLOW CALCULATION, AND AGAIN AS ENTHALPY CHANGE IN THE CAPACITY CALCULATION.
