SAVE ENERGY: USE NATURAL CONVECTION AIR-COOLED EXCHANGERS.

Author(s) : SALLENBACH H. G.

Type of article: Article

Summary

THE ARTICLE REFERS TO NATURAL GAS COOLERS, BUT SIMILAR ARGUMENTS COULD APPLY TO WATER COOLERS OR REFRIGERANT CONDENSERS. THE AUTHOR SHOWS THAT IN FORCED CONVECTION COOLING, FAN ENERGY COSTS ARE MORE SIGNIFICANT THAN EQUIPMENT CAPITAL COSTS. COMPARISON OVER A 17 YEAR LIFE INDICATES A PRESENT WORTH SAVING IN THE REGION OF 40% FOR THE ADOPTION OF MAINLY NATURAL CONVECTION COOLING, BOOSTED WITH FANS FOR ABNORMAL AIR TEMPERATURES ONLY. TO JUSTIFY THIS CONCLUSION, TEST FIGURES ARE SHOWN FOR SEVEN DESIGNS TOGETHER WITH COMPUTED RESULTS AND THE FORMULAE USED TO PRODUCE THEM. SOME USEFUL CONCLUSIONS ARE DRAWN AND COMMENTS INCLUDED TO ASSIST IN NATURAL CONVECTION DESIGN, PARTICULARLY IN THE HEAT TRANSFER ESTIMATES AT THE BORDER BETWEEN LAMINAR AND TURBULENT FLOW. D.W.H.
