for two-effect evaporation experimental facility, the heat transmission coefficient is a critical processing parameter, it determines processing property of evaporation facility.
对于两效蒸发实验装置,传热系数是一个决定性的工艺参数,它直接决定着蒸发设备的工艺性能。
research result indicates that decreasing the outside wall(roof or window) heat transmission coefficient has great effect on increasing total annual heating energy efficient rate;
