复合交变热管复合吸附渔船制冰机的循环特性

研制了一种可以采用渔船柴油发动机余热加热的以复合吸附剂（CaCl₂和活性炭）-氨为工质对的吸附式渔船制冰机.由于采用了复合交变分离热管原理，吸附制冰机解决了用海水直接冷却吸附床带来的腐蚀等问题.建立了小型渔船吸附制冰机试验装置，每个吸附床的复合吸附剂的质量为2.35 kg.试验研究表明，在两床循环中采用回热回质过程系统的制冷功率提高约103.8%，制冷系数（COP）提高了约为100%.在采用回热回质的条件下，制冰工况所得到的单位质量的氯化钙的制冷功率（SCP）约为281.9～712.8 W•kg^-1，相对于目前国内外的研究成果，提高了1.4～3.5倍.

Cycle characteristics of compound alternating heat pipe type compound adsorption ice maker for fishing vessels

An adsorption ice maker for fishing vessels driven by exhausted heat of diesel engine, which used a compound adsorbent(calcium chloride and activated carbon) and ammonia as working pair, was studied.In order to solve the problem of corrosion caused by direct cooling of adsorber by seawater directly, the theory of compound alternating separate heat pipe was adopted.A small test apparatus for the adsorption ice maker was built and the quantity of compound adsorbent in each adsorber was 2.35 kg.The results showed that the cooling power and COP could be improved about 103.8% and 100% respectively by the heat and mass recovery.The SCP of ice making is about 281.9—712.8 W•kg^-1 with heat and mass recovery, which is about 1.4—3.5 times larger than the experimental data on adsorption in and out of China.
