Abstract：
To solve the surface frosting problem of the evaporator in air source heat pump units, studies the effects of the number of rows and fin spaces on the frosting performance of outdoor evaporator, and obtains the varied correlations between evaporator structure parameters and the frost thickness and pressure drop. The experimental results provide a useful reference to optimize structural design and improve operating performance of air source heat pump units.
