Summary

THIS TYPE OF AIR COOLER, USED FOR COMMERCIAL PLANT, HAS SEVERAL SERIOUS DRAWBACKS. IT IS VERY SENSIBLE TO REDUCTION IN HEAT LOAD, THE PERFORMANCE OF THE THERMAL EXPANSION VALVE IS GREATLY INFLUENCED BY THE HEAD PRESSURE AND A SATISFACTORY DISTRIBUTION OF THE REFRIGERANT BETWEEN SEVERAL PARALLEL SECTIONS IS DIFFICULT TO ACHIEVE. IMPROVEMENTS MAY BE CARRIED OUT. THE DEVELOPMENT OF ADVANCED COMPUTER PROGRAMMES MAKES IT POSSIBLE TO OPTIMIZE THE REFRIGERANT SIDE WITH RESPECT TO TOTAL LENGTH OF TUBES, DISTANCE BETWEEN BENDS AND THE USE OF INTERNAL TURBULATORS IN THE TUBES. A PROMISING FUTURE CAN ONLY BE ACHIEVED IF A BETTER WAY OF REFRIGERANT DISTRIBUTION IS FOUND.
