Description

说 明 书
双效回热吸收 -发生系统与回热式第一类吸收式热泵 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：
在第一类吸收式热泵流程中， 回热是提高热泵供热温度的有效方法； 同时， 采用回热还 可以使第一类吸收式热泵具有供热参数可调节、 性能指数实现连续变化和适应变工况运行的 优势。 当余热资源温度相对较低时， 驱动热介质的温降要求大， 此时采用回热， 则完成回热 流程的高温驱动热介质与被加热介质之间具有较大的温差； 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 高第一类吸收式热泵的性能指数。
