介绍了一台固体吸附式太阳能制冷机的设计、制造和试运行情况。它使用活性炭/甲醇作为吸附剂/吸附质对。冰箱有三个主要部件：收集器/发生器/吸附器，冷凝器和蒸发器。其平板型收集器/发生器/吸附器使用有效暴露面积为1.2 m2的透明平面玻璃板。具有正方形平面视图的钢制冷凝器管被浸没在包含在加固的砂混凝土罐中的积水池中。蒸发器是一个浸没在积水中的螺旋形铜管。吸附过程中的吸附剂冷却是通过收集器板和管上方的空气自然对流以及通过移除收集器箱端部盖板而促进的夜空辐射来实现的。吸附物生成和吸附过程中的环境温度在18.5-34 °C之间变化。制冷机从最初温度范围为24-28 °C的水产生超过1.0-8.5 °C的蒸发器温度。相应地，每天产生的最大有效冷却量为266.8 kJ/m2集热器面积。
The design, construction and test run of a solid adsorption solar refrigerator are presented. It used activated carbon/methanol as the adsorbent/adsorbate pair. The refrigerator has three major components: collector/generator/adsorber, condenser and evaporator. Its flat plate type collector/generator/adsorber used clear plane glass sheet of effective exposed area of 1.2 m2. The steel condenser tube with a square plan view was immersed in pool of stagnant water contained in a reinforced sandcrete tank. The evaporator is a spirally coiled copper tube immersed in stagnant water. Adsorbent cooling during the adsorption process is both by natural convection of air over the collector plate and tubes and night sky radiation facilitated by removing the collector box end cover plates. Ambient temperatures during the adsorbate generation and adsorption process varied over 18.5–34 °C. The refrigerator yielded evaporator temperatures ranging over 1.0–8.5 °C from water initially in the temperature range 24–28 °C. Accordingly, the maximum daily useful cooling produced was 266.8 kJ/m2of collector area.
