Description

双效回热吸收 -发生系统与回热式第三类吸收式热泵 技术领域：
本发明属于低温余热利用热泵技术领域。
背景技术：
在采用高温发生器和高温吸收器来实现溶液浓度变化的第三类吸收式热泵流程中， 高温 发生器和高温吸收器之间形成了回热流程， 这不仅能够提高第三类吸收式热泵的供热温度， 也可以使第三类吸收式热泵具有供热参数可调节、性能指数连续化和适应变工况运行的优势。 但是， 当高温驱动热介质与被加热介质之间温差较大时， 若高温驱动热介质的高品位热负荷 只进行一次回热流程， 则会出现温差不能充分利用的情况。 此时， 应该考虑使高温驱动热负 荷进行双效回热流程——将第一次回热流程产生的冷剂蒸汽用于溶液浓度的进一步提升并释 放出用于二次回热的冷剂蒸汽， 则可充分发挥高温驱动热的作用， 充分利用传热温差， 提高 第三类吸收式热泵的性能指数。
