EFFECT OF LIQUID SUBCOOLING AND STATE OF VAPOUR LEAVING THE CALORIMETER ON ACCURACY OF COMPRESSOR REFRIGERATING CAPACITY MEASUREMENT.

Author(s) : MIAO D. P., WU Z. M.

Summary

WHEN DETERMINING THE CAPACITY OF THE COMPRESSOR WITH THE CALORIMETRIC PROCEDURE, THE PRESENCE OF OIL MORE AFFECTS THE ACCURACY OF MEASUREMENT RESULTS IN THE R12 THAN IN THE R22 SYSTEM. THE MEASURING ERROR IS ALL THE MORE HIGHER AS THE SUPERHEATING OF INHALED VAPOUR AND THE SUBCOOLING OF THE LIQUID ARE SMALLER. THE AUTHORS SUGGEST TO EQUIP THE TEST SYSTEM WITH A COOLER ON THE SUCTION PIPE OF THE COMPRESSOR AND A SUBCOOLER ON THE INLET LIQUID PIPE IN ORDER TO OBTAIN MORE ACCURATE RESULTS.
