Summary

RESIDENTIAL ENERGY CONSUMPTION CAN BE DECREASED IF AIR INFILTRATION IS REDUCED. REDUCED AIR INFILTRATION CAN LEAD TO PROBLEMS WITH INDOOR AIR QUALITY (EXCESS HUMIDITY, HIGH LEVELS OF CONTAMINANTS). ONE SOLUTION IS TO INSTALL A RESIDENTIAL AIR TO AIR HEAT EXCHANGER WHICH PROVIDES A CONTROLLED SUPPLY OF VENTILATION AND RECOVERS ENERGY NORMALLY LOST BY AIR INFILTRATION. DISCUSSES THE PERFORMANCE OF RESIDENTIAL HEAT EXCHANGERS, SUMMARISES RESULTS FROM TESTS OF SEVERAL MODELS. COMPARES ENERGY CONSUMED DURING THE HEATING SEASON IN LOW INFILTRATION HOUSES. THE ENERGY REQUIRED TO HEAT VENTILATION AIR IN HOMES EMPLOYING HEAT EXCHANGERS IS 5.3-18.0 GJ LESS THAN IN TYPICAL HOMES. THE HEAT EXCHANGER'S FAN SYSTEM REQUIRED 2.2-3.6 GJ OF ELECTRICAL ENERGY. THE NET PRESENT BENEFIT RANGED FROM -1,350 TO + 2,400 DOLLARS AND DISCOUNTED PAYBACK PERIODS RANGED FROM FIVE TO OVER 30 YEARS. (INT. BUILD. SERV. ABSTR., GB., 18, N.5, 1983, 22, 83-01609.
