Abstract

Heat and mass transfer characteristics of finned-tube heat exchangers under dehumidifying and dry conditions are examined both theoretically and experimentally in the present study. Six types of heat exchangers were tested on an experimental facility. It was determined that there is less than 1 °C of outlet air temperature difference between computer program results and literature for water and R22 as a refrigerant. The outlet air specific humidity difference between them is less than 6.44% for water and 9% for R22. According to the experimental results, louvers on fin cause an increase of airside heat transfer coefficient of about 50% or 100%.
