CAN THE MIXED REFRIGERANT HEAT TRANSFER CHALLENGE BE OVERCOME.

Author(s) : HASELDEN G. G.

Summary

THE POTENTIAL ADVANTAGES OF REDUCED ENERGY CONSUMPTION ACHIEVED BY USING MIXED REFRIGERANTS HAVE BEEN RECOGNISED FOR AT LEAST 30 YEARS BUT THEY HAVE ONLY BEEN REALISED IN THE LIQUEFACTION OF NATURAL GAS. AN IDEAL MIXED REFRIGERANT SYSTEM REQUIRES THAT IN BOTH THE CONDENSER AND EVAPORATOR THE TWO PHASES AT EVERY CROSS-SECTION ARE INTIMATELY MIXED BOTH SEPARATELY AND TOGETHER, AND FLOW CO-CURRENTLY. VARIOUS DESIGNS TO ACHIEVE THIS END ARE DISCUSSED. PUBLISHED METHODS FOR CORRELATING CONDENSING AND EVAPORATING HEAT TRANSFER COEFFICIENTS FOR MIXTURES ARE REVIEWED. GAPS IN PRESENT KNOWLEDGE ARE DISCUSSED,AND GUIDANCE IS GIVEN CONCERNING PRACTICAL HEAT EXCHANGER DESIGNS FOR LARGE AND SMALL SCALE DUTIES.
