本研究探讨太阳能驱动吸附式制冷系统的热物理过程。用于性能研究的数据是在太阳能集热器的启动过程中通过实验获得的。由于太阳辐射的间歇性，在太阳能收集器吸附管内产生高温是一个挑战。在本研究中，太阳能集热器的吸附管，使用颗粒活性炭（GAC 1，GAC 2）和甲醇。所提出的系统可保持高达117.2 °C的较高吸附温度。太阳能吸附式制冷系统的蒸发器温度降至−12 °C（晴天）和0 °C（晴天-阴天），使液态水转化为固态冰。该结果表明，填充有颗粒活性炭和甲醇的太阳能集热器在整个实验期间成功地在太阳能吸附冷却系统内产生冰。一个太阳能泵在白天使融化的冰在储存室内循环，从而将储存室的内部温度分别降低到15 °C和10 °C，持续时间更短和更长。
This study examines the thermophysical process of a solar driven adsorption cooling system. The data used for the performance study were taken experimentally during the start-up procedure of a solar collector. The generation of high temperatures inside a solar collector adsorption tube is a challenge due to the intermittent nature of solar radiation. In this present study, a solar collector adsorption tube using granular activated carbon (GAC1, GAC2) and methanol is introduced. The proposed system maintains higher adsorption temperatures up to 117.2 °C. The evaporator temperature of the solar adsorption cooling system decreased to −12 °C (sunny day) and 0 °C (sunny-cloudy days), allowing liquid water converted to solid ice. This result showed that a solar collector filled with granular activated carbon and methanol successfully produces ice inside the solar adsorption cooling system throughout the experiment period. A solar-powered pump circulated the melted ice inside the storage chamber during day time and thus decreased the inside temperature of storage chamber to 15 °C and 10 °C for shorter and longer durations, respectively.
