吸收法制冷是一种较老的技术。自从发明蒸汽压缩制冷以后,由于其设备更简单,所以应用较普遍,到了七十年代,受到能源危机的激励,人们又注意到了吸收法制冷,以便利用废热或太阳能。本文所介绍的新型吸收式冷/暖机突出的改进在于:用了三段燃气发生器;蒸发、冷凝改用了强化传热管;另外还采用了汽泡泵。 Absorption refrigeration is an older technique. Since the invention of vapor-compression refrigeration, applications have been more common due to its simpler equipment. By the 1970s, inspired by the energy crisis, absorption refrigeration was also noticed in order to utilize waste heat or solar energy. Introduced in this article, the new absorption of cold / warm machine prominent improvement: the use of three gas generators; evaporation, condensation to use enhanced heat transfer tube; also used a bubble pump.
