本文阐述了一种与常规太阳能蒸馏不同的利用冷凝热和海水淡化时释放出的显热系统。经分析,其性能较佳。目前该系统正在埃及施工。如图1所示:它由一台加湿器、一台太阳能蒸馏器或通道,一台冷凝器和一个池子所组成。在加湿器中,进入的环境空气由池子中的温暖盐水加湿加热。如果盐水的出口温度高于环境温度,则返回到池水中,反之,则排出。太阳能蒸馏器是一个长条形玻璃盖板的通道,约长200米。其横载面如图(2)所示。
This article describes a sensible heat system that is different from the conventional solar distillation using condensation heat and seawater desalination. After analysis, its performance is better. The system is currently under construction in Egypt. Shown in Figure 1: It consists of a humidifier, a solar distiller or channel, a condenser and a pool. In the humidifier, the incoming ambient air is humidified by warm brine in the tank. If the brine outlet temperature is higher than the ambient temperature, then return to the pool water, on the contrary, then discharged. Solar distiller is a long strip of glass cover channel, about 200 meters long. Its cross-section as shown in Figure (2).
