Description

分路循环第一类吸收式热泵 技术领域：
本发明属于低温余热利用与热泵／制冷技术领域。
背景技术：
从温差利用角度看，第一类吸收式热泵以驱动热介质与被加热介质之间的温差作为驱动 力，当驱动温差较大时应采用两次或多次温差利用流程来提高温差利用的程度，从而实现热 能利用的高效化；而从工作介质的角度看，吸收式热泵的工作介质为溶液，受物质性质的限 制，每一种溶液都有其适合的工作范围；这样，当驱动热介质的温度和温降超出了单一溶液 的工作范围时，应该采用不同的溶液进行分路循环来完成对驱动温差的充分利用，即驱动温 差分别在不同的溶液循环回路中加以利用，实现驱动温差利用的合理化。
在考虑充分利用温差的同时，第一类吸收式热泵的循环流程还要实现更多的要求，这些 要求包括：热力学参数平滑变化，供热参数可调节，能够较好地适应工况变化，具有最佳的 性能指数；能够实现对高温热源的深度利用，或利用不同品位的热源以实现其综合利用等。
针对显热相对较高的冷剂介质，高温冷剂蒸汽形成的冷剂液具有相对较多的热能和较高 的温度，理应加以利用；通过回热流程将冷剂液的显热释放到被加热介质中，可进一步发挥 高温驱动热的作用和提高低温余热利用率，提高分路循环第一类吸收式热泵的性能指数。
发明内容：

②冷剂蒸汽流经第二发生器2、加热进入其内的溶液释放并向冷凝器7提供冷剂蒸汽， 驱动热在第二个溶液循环回路中实现第二次温降；第二蒸发器9产生的冷剂蒸汽进入第三吸 收器6、被浓溶液吸收并升温，从而实现驱动温差的第二次利用。
③冷剂液流经热交换器18并放热于被加热介质，温度降低之后再经节流阀13节流降压 进入蒸发器8，这有利于获取更多的低温热负荷。
