背景技术 Background technique

目前,我国沿海中小型渔船大都以冰藏保鲜为主,机械制冷保鲜为辅。 At present, China's coastal fishing is mostly in small and medium sized ice storage preservation-based, supplemented by mechanical refrigeration preservation. 因此,渔船制冷机是当前中、小型渔船迫切需要装备的设备,开发研制还是集中在蒸气压缩式制冷方式。 Therefore, current fishing refrigerator is in urgent need to equip small fishing equipment, developed concentrated in the vapor compression refrigeration mode. 与此同时,渔船上的柴油机约有30%的热量从尾气排入大气而浪费。 At the same time, about 30% of diesel on board fishing vessels from the exhaust heat into the atmosphere and waste. 若能利用这部分余热来驱动吸附式制冷系统,即可不增加柴油机任何油耗,仅回收其尾气余热实现制冰,满足渔民的需求。 If we can use this part of the waste heat to drive sorption refrigeration systems, no additional fuel to the diesel engine, which exhaust heat recovery achieved only ice, to meet the needs of the fishermen.

目前所研究的船用吸附制冷设备,主要采用水、氨以及甲醇为制冷剂,其中采用水、甲醇为制冷剂的系统一般采用物理吸附剂,相对于采用化学吸附剂—氨为工质对的系统而言,制冷量偏小。 The present study marine adsorption refrigeration equipment, mainly water, methanol and ammonia as a refrigerant, wherein the use of water, methanol as a refrigerant system generally using physical adsorbents with respect to the chemical adsorbent - ammonia as working fluid of the system , the cooling capacity is too small. 考虑到相容性,对于氨系统吸附床一般采用钢材料,由于海水与钢材料之间具有不相容性,所以目前采用氨为制冷剂的系统一般不能采用海水直接冷却,否则会存在严重的腐蚀问题。 View of compatibility, the system for the ammonia adsorbent bed is generally made of steel materials, because of incompatibility between the seawater and the steel material, currently used ammonia refrigerant systems generally can not be directly cooled using seawater, otherwise there is a serious corrosion problems. 渔船用吸附制冷设备,目前所采用的吸附床形式多为单元管式与壳管式。 Fishing adsorption refrigeration equipment currently used in the form of the bed multi-tube units with a shell and tube.
