THE SEARCH FOR CHILLER EFFICIENCY.

Author(s) : LANDMAN W. J.

Type of article: Article

Summary

THE ARTICLE IDENTIFIES THE POINTS IN A CENTRIFUGAL COMPRESSOR, WATER CHILLING PLANT WHERE LOSSES OCCUR IN THE CONVERSION OF INPUT POWER TO CHILLING OUTPUT. IN HEAT TRANSFER, THE FACTORS WHICH MAY BE IMPROVED INCLUDE THE WATER AND REFRIGERANT FILM COEFFICIENTS, WHICH ALSO INVOLVE CONFIGURATIONS OF TUBE DESIGN. CYCLE THERMODYNAMIC EFFICIENCY IS DEPENDENT MAINLY ON THE REFRIGERANT USED AND ONTHE ECONOMIC POSSIBILITIES OF STAGED COMPRESSION AND INTERCOOLING. OTHER LOSSES OCCUR IN THE MOTOR, THE DRIVE AND THE COMPRESSOR ITSELF. THE AUTHOR THINKS THAT LITTLE IMPROVEMENT IS AVAILABLE OTHER THAN THE CHOICE OF THOSE COMPONENTS ALREADY REACHING THE BEST POSSIBLE EFFICIENCIES. D.W.H.
