| 摘 要： | 制冷剂CO2在蒸发器内的流动换热性能受许多因素的影响，比如：质量流速、热流密度以及蒸发温度等参数。由于CO2特殊的热物性和传输性，使得其蒸发换热和两相流特点有别于传统制冷剂。这也决定了其蒸发换热管适合设计成小管径，而蒸发器的型式以紧凑型为发展方向。

| Abstract: | The boiling heat transfer performance of refrigerant carbon dioxide in evaporators is influenced by many factors,such as the mass flux,heat flux and evaporation temperature,etc.. Because of its special thermo-physical and transport properties,the heat transfer and two-phase flow characteristics are very different from conventional refrierants.The evaporating heat transfer tube of carbon dioxide is suitable to use small diameter.Therefore,developing compact evaporator is very competitive. |

| Keywords: | refrigerant carbon dioxide boiling heat transfer dry-out evaporator |
