采用复合吸附剂-氨工作对设计出多功效热管型高效吸附制冷系统.CaCl2/活性碳的复合吸附剂,由于活性碳中丰富的微孔结构强化了CaCl2的传质,提高了系统的吸附性能.系统在加热吸附床时,加热锅炉为热管加热端,吸附床为热管冷却端;在冷却吸附床时,吸附床为热管加热端,冷却器为热管冷却端;在回热时,热的吸附床为热管加热端,冷的吸附床为热管冷却端;回质时,将热的吸附床和冷的吸附床的氨管路相连通,由于热床压力高,其中的氨将迅速流到冷床中而实现回质.在渔船柴油机余热加热,海水冷却的条件下,系统在?20℃蒸发温度下可以获得单位质量吸附剂的制冷功率,SCP=770.4W/kg,COP=0.39.在太阳能热水驱动下,系统在蒸发温度为5.6℃时可以获得单位质量吸附剂制冷功率,SCP=524.2W/kg,COP=0.27.
Adopting composite adsorbent-ammonia work to design multi-effect heat pipe type high efficiency adsorption refrigeration system.CaCl2 / activated carbon composite adsorbent, due to the rich micropore structure in activated carbon, strengthen the mass transfer of CaCl2 and improve the adsorption performance of the system When the system is heating the adsorption bed, the heating boiler is the heating end of the heat pipe and the adsorption bed is the cooling end of the heat pipe; when cooling the adsorption bed, the adsorption bed is the heating end of the heat pipe and the cooler is the cooling end of the heat pipe; The bed is the heating end of the heat pipe, and the cold adsorption bed is the cooling end of the heat pipe; when the quality is returned, the hot ammonia adsorbent bed and the cold adsorption bed are connected to the ammonia pipeline, the ammonia in the hot bed will rapidly flow to the cold Bed in order to achieve back quality.When the fishing boat diesel engine waste heat heating, seawater cooling conditions, the system can be obtained at 20 ℃ evaporation temperature per unit mass of adsorbent refrigeration power, SCP = 770.4W / kg, COP = 0.39 in the solar Driven by hot water, the refrigeration power of unit mass adsorbents can be obtained when the evaporation temperature is 5.6 ℃, SCP = 524.2W / kg and COP = 0.27.
