随蒸发器蒸发温度的升高，两种蒸发器的蒸发功率都呈线性增加，相同工况下，细薄膜蒸发器的蒸发功率约为普通光管蒸发器蒸发功率的2倍；2. 随蒸发温度的升高，细薄膜蒸发器的进出口壁面温差明显低于普通光管蒸发器，光管蒸发器的平均传热温差比细薄膜蒸发器高出约2℃；3.对应每个工况下，细薄膜蒸发器的换热系数明显高于普通光管蒸发器，0~5℃时，细薄膜蒸发器能保持较高的换热系数，换热系数在蒸发工况为5℃时达到最大值。实验数据和结论说明细薄膜蒸发器的传热性能明显优于普通光管蒸发器，其应用值得推广。

 A novel thin film evaporator was designed based on thin film evaporating theory and combined it with a compression refrigeration system, which did an intensive study on novel thin film evaporator’s heat transfer performance, the following experiment conclusions are obtained: 1. Two kinds of evaporators’ cooling capacity increases linearly with evaporating temperature, under the same working condition, thin film evaporator’s cooling capacity is two times larger than common smooth tube evaporator’s; 2. As evaporating temperature increases, thin film evaporator’s inlet and outlet temperature difference is significantly lower than smooth tube evaporator’s, smooth tube evaporator’s average heat transfer temperature difference is 2℃ higher than thin film evaporator’s; 3. Regarding to each working condition, thin film evaporator’s heat transfer coefficient is obviously larger than smooth tube evaporator’s, when the temperature is between 0~5℃, thin film evaporator can maintain a relatively high heat transfer coefficient, heat transfer coefficient reaches the maximum value when it’s at 5℃’s working condition. The experiment data and conclusions demonstrate that thin film evaporator’s heat transfer performance has an advantage over smooth tube evaporator’s, it’s worthy promoting thin film evaporator’s development and use.
