| 摘 要： | 为提高淡水产量,设计一种太阳能负压式太阳能加湿除湿海水淡化系统,通过减小加湿腔体内压强来增加湿空气中含湿量,湿空气分别在液环真空泵和除湿腔内冷凝收集得到淡水。湿空气中含湿量上升,日产淡水总量增加。当湿空气温度70 ℃时,加湿腔压强从90 kPa减至70 kPa,含湿量增加154.9 g/kg;加湿腔压强70 kPa时,12：00—14：00可稳定产淡水1.8 kg/h以上,最高可达2.1 kg/h。装置性能系数GOR最高可达1.7。

| Abstract: | In order to increase the freshwater production, a solar humidification and dehumidification system under sub-atmospheric pressure for desalination is proposed. The moisture content of the humid air increased by decreasing the humidifier pressure. The freshwater is collected in the liquid ring vacuum pump and the dehumidifier. The freshwater production increases when the moisture content in humid air increases. The humidifier pressure decreases from 90 to 70 kPa, the humidity can increase 154.9 g/kg when the humid air temperature is 70 ℃; When the humidifier pressure is 70 kPa, the freshwater is above 1.8 kg/h from 12:00 to 14:00 and the maximum output is 2.1 kg/h. The GOR reaches up to 1.7. |
