摘要
提出一种包含吸收溶液冷却结晶过程的新型第二类吸收式热泵循环,并对其工作过程及性能特性进行理论分析与实验研究。结果表明,该循环可在吸收器吸收溶液质量分数显著高于发生器吸收溶液质量分数的条件下工作,其热泵温升能力明显优于现有AHT循环。当冷却结晶终温和冷凝器温度为35℃、发生器温度和蒸发器温度为92℃时,其热泵温升理论上可达97℃。
A new absorption heat transformer cycle including a process of absorption solution' s cooling and crystallization was proposed and the system performance was analyzed. The results showed that the new cycle can operate under such an ideal condition that the concentration of absorption solution in absorber is obviously higher than which in generator, so it can achieve a much greater heat pump temperature lift than the current AHT cycle under the same conditions. While the temperature of crystallizer and condenser is 35℃, and the temperature of generator and evaporator is 92℃, a heat pump temperature lift of 97℃ is obtained according to performance analysis of the new AHT cycle.
