| 摘 要： | 对以氨／水为工质的中压双效复叠吸收式冷循环进行计算分析发现，只有在冷却水温度较低，制冷剂蒸发温度较高的条件下，才能显示其具有较高制冷系统的优点，当冷却水温度较高时，循环冷系数较考虑回收Ⅰ级循环的精馏热，以提高叠循环的制冷系统。

| Abstract: | A double effect cascade absorption refrigeration cycle in middle pressure using ammonia and water as working fluids is calculated and analyzed in this paper. It is found that the cycle has an advantage of high coefficient of performance (COP) only in the condition that the cooling water temperature is low and the evaporation temperature of refrigerant is high. When the cooling water temperature is high, COP of the cycle is low. In that condition, to recover the rectifying heat in I stage cycle for raising COP need to be considered. |
