工作对H2O/LiBr的几个高级循环，基本上结合了吸收式热泵和热泵的优点。介绍了变压器的结构和工作原理。这些循环特别适合于提供工艺热，同时回收该工艺的废热。与两个基本循环相比，热比和节能明显更高，而每次节能的投资成本预计将降低，从而缩短投资回收期。这些热泵变压器可以用作蒸馏、蒸发和干燥过程等的供热系统，从而补充或取代化学、食品和饮料、造纸和纸浆或海水淡化行业中的机械蒸汽再压缩。在一次能源消耗方面，这些系统可以与机械压缩机竞争。 将这种热泵变压器用作多级海水淡化厂的供热系统，将所需的阶段数从16个减少到3个，其余三个阶段都在接近大气压的条件下运行。类似的说法适用于其他多级蒸馏过程。单位:SICitation:研讨会，ASHRAE交易，1985年，第91卷，pt。你好，檀香山2B

Several advanced cycles for the working pair H2O/LiBr, which essentially combine the advantages of an absorption heat pump with those of a heat. transformer, are presented. These cycles are particularly suited for providing process heat and simultaneously recovering reject heat from that process. The heat ratios and thus the energy savings are appreciably higher than those for the two basic cycles, whereas the investment costs per energy saving are expected to be reduced, thus yielding shorter payback times. These heat pump - transformers can be used as heat supply systems for distillation, evaporation, and drying processes, etc., and thus complement or replace mechanical vapor recompression in the chemical, food and beverage, paper and pulp, or water desalination industries. With respect to primary energy consumption, these systems can compete with mechanical compressors.Applying such a heat pump - transformer as a heat supply system to a multistage water desalination plant reduces the number of required stages from 16 to 3, with the remaining three stages all operating at close to atmospheric pressure. Similar statements hold for other multistage distillation processes.Units: SI
