这项研究的主要目标是为生活在阿曼偏远地区的贝都因人（如沙漠）设计和建造一个负担得起的太阳能热电冰箱，那里仍然没有电力供应。冰箱可用于储存易腐物品，并方便运输必须在低温下储存以保持有效性的药物和生物材料。太阳能冰箱的设计基于热电模块的原理（即，珀耳帖效应）以产生热侧和冷侧。热电模块的冷侧用于制冷目的;为冰箱空间提供冷却。另一方面，来自模块的热侧的热量通过使用散热器和风扇被排出到周围环境。对所设计的太阳能热电制冷器进行了制冷实验。结果表明，制冷的温度从27摄氏度降低到5摄氏度，在大约44分钟。制冷机的性能系数（COPR）进行了计算，发现约为0.16。(c)2008爱思唯尔有限公司保留所有权利。
The main objective of this study is to design and build an affordable solar thermoelectric refrigerator for the Bedouin people (e.g. deserts) living in remote parts of Oman where electricity is still not available. The refrigerator could be used to store perishable items and facilitate the transportation of medications as well as biological material that must be stored at low temperatures to maintain effectiveness. The design of the solar-powered refrigerator is based on the principles of a thermoelectric module (i.e., Peltier effect) to create a hot side and a cold side. The cold side of the thermoelectric module is utilized for refrigeration purposes; provide cooling to the refrigerator space. On the other hand, the heat from the hot side of the module is rejected to ambient surroundings by using heat sinks and fans. The designed solar thermoelectric refrigerator was experimentally tested for the cooling purpose. The results indicated that the temperature of the refrigeration was reduced from 27 degrees C to 5 degrees C in approximately 44 min. The coefficient of performance of the refrigerator (COPR) was calculated and found to be about 0.16. (c) 2008 Elsevier Ltd. All rights reserved.
