气体制冷冰箱美国洛斯·阿拉莫斯国家实验室研制成功的这种冰箱,不需要压缩机和制冷液,简化了冰箱结构,大大降低了成本。它采用受压发热,膨胀吸热制冷原理。结构内装有一个充满氦等惰性气体的圆桶,桶的一端密封,另一端是电磁振动装置。该装置由振动膜、膜盒、音圈、磁铁等组成。象喇叭一样,通电后磁铁上的音圈带动振动膜振动,使桶内气体压缩和胀膨,热量经桶外的散热片散发,达到制冷效果。这对传统冰箱将是一个重大改进。不用氟里昂的蒸汽冰箱这种不用电、不用氟里昂、没有运动部件的固体吸附式蒸汽冰箱由湖南大学研制成功。固体吸附式蒸汽冰箱是用固体物质作吸附剂, Gas Refrigeration Refrigerator The refrigerator, developed by Los Alamos National Laboratory in the United States, does not require compressors and refrigeration fluids, simplifying the construction of the refrigerator and greatly reducing costs. It uses compression heat, expansion of heat absorption cooling principle. Inside the structure is a drum filled with an inert gas such as helium. One end of the barrel is sealed and the other end is an electromagnetic vibrator. The device consists of a diaphragm, diaphragm, voice coil, magnet and other components. Like a speaker, the voice coil on the magnet drives the vibrating diaphragm to vibrate when the power is on, so that the gas in the barrel is compressed and expanded. The heat is dissipated through the heat sink outside the barrel to achieve the cooling effect. This will be a major improvement over traditional refrigerators. Do not use Freon’s steam refrigerator without electricity, without Freon, no moving parts solid adsorption steam refrigerator developed by Hunan University. Solid adsorption steam refrigerator is a solid material used as adsorbent,
