REVIEW OF AUTOMOTIVE AIR CONDITIONER DRYDOWN RATE STUDIES: THE KINETICS OF DRYING R12.

Author(s) : COHEN A. P., DUNNE S. R.

Summary

THE STUDIES WERE DONE IN THE LABORATORY ON AN AUTOMOTIVE AIR-CONDITIONING SYSTEM AND A LIQUID-REFRIGERANT CIRCULATING SYSTEM. DRYDOWN TIME CONSTANTS FOR EACH SYSTEM AND MASS TRANSFER COEFFICIENTS FOR THE DRYING OF R12 WERE DETERMINED THE RECEIVER/DEHYDRATOR DESIGN (HIGH SIDE, LIQUID PHASE, FLOW-BY) HAD THE MOST RAPID DRYDOWN RATE. ITS DRYING RATE WAS 2 ORDERS OF MAGNITUDE FASTER THAN THE SLOWEST DESIGN, THE ACCUMULATOR/DRIER (LOW SIDE, LIQUID PHASE, FLOW-BY). TYPE 4A MOLECULAR SIEVE WAS ABOUT 4 TIMES FASTER THAN SILICA GEL.
