| Abstract: | 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 ⁰F (26.7⁰C)db. The cycling study consisted of twelve transient tests conducted with an outdoor temperature of 95⁰F (35⁰C) 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 67⁰F (19.4⁰C) wet-bulb (wb) for evaporator airflows ranging from 50% below to 37.5% above rated airflow. Outdoor temperatures of 85⁰F (29.4⁰C) db, 95⁰F (35⁰C) db, and105⁰F (40.6⁰C) 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 67⁰F (19.4⁰C) wb for outdoor exposure times of 0, 2000, 4000, and 8000 hours. Outdoor temperatures of 82⁰F (27.8⁰C) db and 95⁰F (35⁰C) db were also considered. |
