Abstract:

A solution cooling absorption(SCA)approach is proposed to modify the aqueous ammonia absorption refrigerat-ion cycle using the strong solution from the absorber to cool the forepart of the absorption in the cycle for reclaiming some portion of absorption heat.As a consequence of raised temperature at the inlet, the strong solution partially boils at the outlet of the solution heat exchanger, and diminishes the thermal heat consumption of the heat source.The calculation results show that the coefficient of performance(COP)of this modified cycle is about 28.3% higher than that of the traditional cycle under typical conditions;while the required heat transfer area of the total heat exchangers of the cycle is somewhat less than that of the traditional one.The capacity of refrigeration with the new absorption cycle is more than doubled in contrast to the adsorption scheme with an identical configuration.It is sufficient to supply a fishing boat the chilling capacity for preservation of fishing products with the modified cycle chiller driven by its diesel engine exhaust.

提出了一种溶液冷却吸收的氨水吸收式制冷循环方案, 即利用来自吸收器的浓溶液冷却吸收过程的前半部分以回收部分吸收热.由于进入溶液热交换器的浓溶液温度提高, 在其出口浓溶液将部分沸腾, 因而可减少外界热源的消耗.计算结果显示, 在典型条件下改进循环的性能系数(COP)比传统循环提高约28.3%, 而该循环所有换热器所需的总换热面积则比传统循环略有减少.在同等条件下与吸附式制冷方案相比, 改进循环的制冷量可增加1倍多.渔船采用改进循环的制冷机后用其自身柴油机废气足以提供渔品保鲜用的制冷量.
