TO-22-002 – Energy and Dehumidification Performance Investigation of Different Fan Control Modes of Split Residential Air Conditioners in Hot and Humid Climates

Click here to purchase
Split residential air conditioners with a variable-speedfan have three fan control modes: AUTO, ON, and ENHANCED.This paper investigates their energy and dehumidificationperformance by evaluating coefficient of performance (COP),sensible heat ratio (SHR), and indoor air humidity throughexperiments at a residence in Miami, Florida. The resultsreveal that the COP remains approximately constant and theSHR decreases as the airflow rate decreases. Thus, the fanoverrunning in the ON and ENHANCED modes significantlyincreases the indoor air humidity. Overall, the AUTO mode withappropriate airflow rate has the best energy and dehumidificationperformance.
