THREE BALANCED AIRFLOW VENTILATION DEVICES WERE EVALUATED, AN EXHAUST AND SUPPLY FAN, AIR-TO-AIR HEAT EXCHANGER, AND EXHAUST AIR HEAT PUMP (EAHP), WHICH CAN BEUSED TO INCREASE THE VENTILATION RATE IN AN R-2000 (TIGHTLY CONSTRUCTED) TYPE HOUSE. A PROTOTYPE OF THE EAHP, WHICH USES A COMBINATION OF HEAT PIPE AND HEAT PUMP, WAS BUILT AND TESTED. A FROSTING AND NONFROSTING VERSION OF THE EAHP WERE EVALUATED. THE NONFROSTING VERSION PROVIDED THE BEST OVERALL PERFORMANCE. THE COP OF THE NONFROSTING UNIT HAS A MAXIMUM OF 4.8 AT 263 K (-10 DEG C) AND A MINIMUM OF 2.4 AT 248 K (-25 DEG C).
