Three experimental studies were conducted to quantify the effects of system
cycling, evaporator airflow, and condenser coil fouling on the performance of residential
air conditioners. For all studies, the indoor dry-bulb (db) temperature was 80°F (26.7°C)
db. The cycling study consisted of twelve transient tests conducted with an outdoor
temperature of 95°F (35°C) db for cycle times of 6, 10, 15, and 24 minutes. Indoor
relative humidities of 40%, 50%, and 60% were also considered. The evaporator airflow
study consisted of twenty-four steady-state tests conducted with an indoor condition of
67°F (19.4°C) wet-bulb (wb) for evaporator airflows ranging from 50% below to 37.5%
above rated airflow. Outdoor temperatures of 85°F (29.4°C) db, 95°F (35°C) db, and
105°F (40.6°C) db were also considered. The coil fouling study used a total of six
condensers that were exposed to an outdoor environment for predetermined amounts of
time and tested periodically. Three of the condensers were cleaned and retested during
the periodic testing cycles. Testing consisted of thirty-three steady-state tests conducted
with an indoor condition of 67°F (19.4°C) wb for outdoor exposure times of 0, 2000,
4000, and 8000 hours. Outdoor temperatures of 82°F (27.8°C) db and 95°F (35°C) db
were also considered.
