摘　　要：为探究冷却结露式空气取水装置的取水性能,建立预测取水装置实际取水量的模型,实验研究了蒸发器进风量及膨胀阀开度对装置取水量的影响,对不同温度、相对湿度条件下取水装置的取水性能进行分析。实验结果表明:蒸发器进风量过大,湿空气与翅片热交换反应不充分,取水量降低;膨胀阀开度越小,蒸发器翅片温度与空气露点温度差越大,取水量升高;相同露点温度条件下,低温-高相对湿度状态比高温-低相对湿度状态的取水量更高;在空气温度22~34℃、相对湿度30%~70%条件下,取水量为6 000~15 900 mL/h;实际取水量与理论取水量存在明显差异,引入取水系数可降低预测误差。In order to study the performance of a condensing water extraction device from air and to develop a model for predicting the actual water yield,experiments were conducted to study the effects of evaporator airflow volume and expansion valve opening on the water yield and to analyze the water extraction performance under different temperatures and relative humidity conditions.The results show that the evaporator airflow volume is too large,the wet air and fin heat exchange reaction is not sufficient,and water yield was reduced;the smaller the expansion valve opening,the greater the difference between the evaporator fin temperature and the air dew point temperature,and the higher the water yield;for the same dew point temperature,the low temperature and high relative humidity condition has a higher water yield than the high temperature and low relative humidity condition;under the conditions of air temperature 22~34℃and relative humidity 30%~70%,the water yield is 6000~15900 mL/h;there is a significant difference between the actual water yield and the theoretical water yield,and the introduction of the water extraction coefficient can reduce the prediction error.
