Abstract
Air side heat transfer coefficient is a key problem to study thermal regime of air-cooled units. Five commonly used equations for calculating the heat transfer coefficient of wavy finand tube heat exchanger of air source heat pump and scope of application were analyzed. According to the typical example, all the solutions of equation are calculated for the five methods. Comparing between theoretical data and experimental data, the experimental results are basically consistent with the theoretical solution J factor method and McQuiston method is recommended as the optimal method for calculating the heat transfer coefficient of wavy fin and tube heat exchanger. It is provided theoretical basis on optimal design and thermal characteristics.
