摘要
A special wind tunnel facility was used to research the evaporative cooling performance of compound test specimen forming from porous decorate layer, waterproof mortar layer and concrete base. The analysis results indicate that the normalized root mean square error between the measurement values and input values of environment parameter in different stages of wind tunnel experiment are less than 4%. The evaporative process of wet specimen will cumulatively consume about 80% shortwave radiation heat in daytime. Furthermore, the albedoes of dry and wet specimens were 0.406 ±0.040 and 0.181 ±0.018, respectively.
