HIGH SIDE PIPING AND PURGING.

Author(s) : BROWN R.

Summary

THE AUTHOR POINTS OUT HOW PROPER CONDENSER PIPING AFFECTS THE ABILITY AND EFFICIENCY OF PURGING NON-CONDENSABLES FROM A REFRIGERATION SYSTEM. OVER THE PAST FIVE YEARS EXTENSIVE USE HAS BEEN MADE OF THERMOSIPHON OIL COOLING AND DESIGN HEAD PRESSURES OF 650 KILOPASCALS AT LOW AMBIENT CONDITIONS SINCE THESE SYSTEM FEATURES WILL ADD TO THE DESIGN PARAMETERS THAT MUST BE TAKEN INTO ACCOUNT FOR EFFECTIVE AND SUITABLE CONDENSER PIPING. TO ILLUSTRATE HIS POINTS THE AUTHOR HAS USED, AS AN EXAMPLE, A MULTIPLE EVAPORATIVE CONDENSER PIPING CIRCUIT WITH THERMOSIPHON COOLING AS IT PRESENTS MOST OF THE PIPING PROBLEMS THAT MIGHT BE ENCOUNTERED. SEVERAL ILLUSTRATIONS DEPICT SYSTEM CONDITIONS AT VARIOUS WET BULB TEMPERATURES AND CONDENSER DISCHARGE PRESSURES. THE REPORT CONCLUDES WITH RECOMMENDATIONS ON THE USE OF VARIOUS COMPONENTS IN THE SYSTEM PIPING AND AN ASHRAE STANDARD ON PIPE SIZING. A. H. S.
