为提高废气/水中可用热能的利用效率，提出了一种改进的单效/双升式高效吸收式制冷循环。改进后的循环采用蒸发器/吸收器(E/A)，提高了性能系数，减少了不可逆损失。以水-溴化锂为工质对，进行了稳态工况下的模拟研究。结果表明，与传统的单效循环相比，废气排放温度降低了约20℃，在模拟工况下，我们提出的新型循环可以获得更大的单位质量废气/水的制冷量。
To increase the use efficiency of available thermal energy in the waste gas/water, a novel high-efficient absorption refrigeration cycle regarded as an improved single-effect/double-lift configuration is proposed. The improved cycle using an evaporator/absorber (E/A) promotes the coefficient of performance and reduces the irreversible loss. Water–lithium bromide is used as the working pair and a simulation study under the steady working conditions is conducted. The results show that the temperature of waste gas discharged is about 20 °C lower than that of the conventional single-effect cycle and the novel cycle we proposed can achieve more cooling capacity per unit mass of waste gas/water at the simulated working conditions.
