In order to understand the frosting rules and the performance of fin-tube heat exchanger in th.

The airside heat transfer and pressure drop characteristics of fin-tube heat exchangers are the key issue studied by many researchers in HVAC field.

This paper improved the equation of calculating the water vapor supersaturation degree at frost surface,and described a numerical model which uses supersaturated water vapor at the frost surface to predict the frost growth for finned-tube heat exchangers.

The effect on the growing rate, the yield of frost and the pressure drop with the characteristic of finned-tube heat exchanger, such as the span, shape and the surface status of the fin were investigated experimentally.

To improve the heat transfer performance of finned tube heat exchanger,according to the field synergy principle(under the condition of same speed and the temperature boundaries,convective heat transfer is decided by synergy between the fluid speed field and heats field),utilizes the oval tube instead of the circle one.

Knowledge based genetic-simulated-annealing method for optimizing tube circuit of fin-and-tube heat exchangers;

Optimization approach for tube circuit of fin-and-tube heat exchanger based on genetic algorithm;

Air side heat transfer and friction characteristics in three nine-row and three twelve- row fin-and-tube heat exchanger cores with varied types of fin configurations are experimentally investigated.

Frosting of finned tube heat exchangers is a complex process of heat and mass transferunder low temperature conditions.

Numerical calculation is presented on a two-row plain-finned tube heat exchanger.

Finned tube heat exchangers are applied in industry for a long time, while the heat transfer enhancement of the finned tube heat exchangers has become one of the important research area in academia.
