VENTILATION EFFICIENCIES OF WALL OR WINDOW MOUNTED RESIDENTIAL AIR-TO-AIR HEAT EXCHANGERS.

Author(s) : OFFERMANN F. J.

Summary

MECHANICAL VENTILATION SYSTEMS WITH AIR-TO-AIR HEAT EXCHANGERS CAN BE INSTALLED TO PROVIDE ENERGY-EFFICIENT SUPPLEMENTARY VENTILATION FOR THE PURPOSE OF CONTROLLING INDOOR CONCENTRATIONS OF CONTAMINANTS. WALL-OR WINDOW-MOUNTED UNITS ARE RELATIVELY INEXPENSIVE AND EASY TO INSTALL. BECAUSE THEY LACK AN AIR-DISTRIBUTION SYSTEM, CONCERN HAS ARISEN OVER THEIR VENTILATION PERFORMANCE. A SERIES OF EXPERIMENTS WAS CONDUCTED ON 2 MODELS. THE NOMINAL VENTILATION EFFICIENCIES HAVE BEEN DETERMINED BY MEASUREMENT OF TRACER-GAS DECAY RATES AT SEVERAL INDOOR LOCATIONS. NO SIGNIFICANT CORRELATIONS BETWEEN NOMINAL VENTILATION EFFICIENCY AND HEAT EXCHANGER MODEL OR OPERATIONAL STRATEGIES WERE OBSERVED. HIGHER LOCAL VENTILATION EFFICIENCIES WERE NOTED IN THE ROOMS WHERE THE HEAT EXCHANGERS WERE OPERATING.
