EXPERIENCE WITH ECONOMIZER APPLICATIONS IN HEAT RECOVERY-HEAT PUMP SYSTEMS: THE POSITIVE AND THE NEGATIVE.

Author(s) : MCFARLAN A. I.

Summary

THE AUTHOR DETAILS MANY POINTS IN THE DESIGN OF OPTIMAL ENERGY BUILDING ENVIRONMENTAL SYSTEMS. QUOTING ONE BUILDING AS AN EXAMPLE, HE EXPLAINSTHE FREQUENT MISUSE OF OUTSIDE AIR AS A COOLING MEDIUM AND THE FAILURE OF MANY HEAT-PUMP SYSTEMS THROUGH INSUFFICIENTLY HIGH CONDENSING TEMPERATURES BEING AVAILABLE. HIGH RANGE COILS ENABLE A COMMON THIRD PIPE TO BECOME BOTH COOLING AND HEATING RETURN WITHOUT LOSS OF ECONOMY, AND STAGED CHILLERS AND CONDENSERS IN COUNTERFLOW ALLOW HIGH CONDENSING AND HIGH EVAPORATING TEMPERATURES TO BE MATCHED. THE EXPLANATIONS ARE ILLUSTRATED BY A COMPLEX SYSTEM BROKEN DOWN TO PART-SYSTEM DIAGRAMS FOR EACH MODE OF OPERATION. D.W.H.
