THE MEASUREMENT OF THE PERFORMANCE OF REFRIGERATION PLANT.

Author(s) : GIGIEL A. J.

Type of article: Periodical article

Summary

TO OBTAIN A SATISFACTORY OVERALL VIEW OF REFRIGERATION PLANT PERFORMANCE THE AUTHOR HAS USED A COEFFICIENT OF SYSTEM PERFORMANCE (COSP), DEFINED AS USEFUL REFRIGERATION EFFECT DIVIDED BY TOTAL ENERGY SUPPLIED TO SYSTEM. THE LATTER INCLUDES ENERGY FOR FANS, PUMPS, DEFROST HEATERS, ETC, AND NORMALLY CAN BE MEASURED AS ELECTRICAL INPUT. THE FORMER REQUIRES THE SIMPLE APPLICATION OF REFRIGERANT TEMPERATURE, PRESSURE AND FLOW RATE MEASUREMENT. A PORTABLE UNIT IS DESCRIBED USING A NEW FORM OF FLOW MEASUREMENT, EASILY INSERTED IN A LIQUID LINE, THERMISTORS FOR PIPE-WALL MOUNTING AND PRESSURE TRANSDUCERS ALL COUPLED TO A DATA LOGGER. THE RECORDED DATA WAS COLLECTED ON A TAPE CASSETTE FOR FEEDING INTO A MINI-COMPUTER FOR ANALYSIS. TESTS ON A PIG-CHILLING ROOM INDICATED A COSP ON AVERAGE AS LOW AS 0.6 FOR A SYSTEM WITH A NORMAL COP OF ABOUT 8. THE METHOD COULD BE USEFUL THEREFORE IN INDICATING ENERGY SAVING POSSIBILITIES.
