摘要
设计了连续而又稳定循环的三效吸附式热泵单元─-三效冷环,使各吸附床的吸附循环之间具有先后连贯性,既可避免吸附床的过热,又能消除热泵输出端的不稳定工作状态,使得热泵系统的COP值、效率以及各吸附循环的效率均有显著提高。此外,单元化使三效冷环易于长期维持真空度,便于根据余热量的大小进行并联组合成较大的热泵系统。
n this paper,the design concept of a tri-coupled cycle absorption heat pump unit is proposed under thermodynamic analysis.Due to the three absorption beds designed working in series. the heat pump will have the advantages of avoiding overheating of absorption beds and eliminating the unsteady output so as to improve the COP,exergy efficiency of the heat pump as well as the efficiency of each absorption cycle.Besides,the moduled heat pump concept will make cooling cycle easy to keep vacuum in long term and is flexible to be assembled into a large heat pump system according to the amount of waste heat available.
