Type of article: Article

Summary

THE AUTHOR ARGUES THE CASE FOR VARIABLE AIR VOLUME AIR CONDITIONING SYSTEMS, FIRST BY MAKING A SIMPLE COMPARISON OF SAVINGS IN REFRIGERATION AND FAN ENERGY AGAINST A CONSTANT-VOLUME, ZONAL-REHEAT SYSTEM AND DISCUSSES THE TYPE OF LOAD PROFILE FOR WHICH THE BEST SAVINGS CAN BE MADE, BUT WITHOUT REFERENCES TO FRESH AIR REQUIREMENTS OR HUMIDITY CONTROL WHICH MAY NEGATE SOME OF THE PROFILES ILLUSTRATED. ALTERNATIVE SYSTEMS INCORPORATING VAV WITH TERMINAL RE-HEAT OR DUAL-DUCT FACILITIES ARE DISCUSSED AND THEIR SELECTION SUGGESTED FOR PARTICULAR APPLICATIONS. METHODS OF FAN VOLUME CONTROL ARE EXPLAINED INCLUDING INLET GUIDE VANES APPLIED TO FORWARD CURVED CENTRIFUGAL FANS. THE ARTICLE CONCLUDES WITH A DISCUSSION OF DIFFUSERS AND THE COANDA EFFECT TO PREVENT DUMPING, AND METHODS OF CONTROL. D.W.H.
