中文摘要：
以溴化锂/水为基础,提出了适用于余热驱动的吸收式蓄能工质对的遴选原则,并结合蓄能实验对文献中的工质对进行了评价。在遴选原则下,结合经济性,对文献提出的2种具有较好的蓄能/释能特性的工质对进行了改良,并提出了2种新的适用于余热驱动的吸收式蓄能工质对。采用实验的方法给出了2种新工质对的蒸气压特征和蓄能特性。重点介绍了蓄能特性参数的测量装置及数据。从获得的实验数据中可以看出,提出的2种吸收式工质对都可以有效地降低蒸气压、具有较好的释能潜力。通过比较不同热源温度下蓄存单位制冷剂所吸收的热量,指出2种吸收式工质对和Li Br/H2O适用于热源温度为380-400 K的低温余热驱动的吸收式蓄能机组。
英文摘要：
Criteria regarding the selection of suitable Li Br/H2 O based working pairs for absorption energy storage systems driven by waste heat were proposed. The energy storage/release properties of working pairs in the literatures were also evaluated in our previous experiments. Under the guidance of the selection criteria, two new working fluids, based on the two existing working pairs but with better economy, were proposed. Experiments were undertaken to study the vapor pressures and the energy storage/release properties of both the new working fluids. The energy storage/release experiment has been introduced in detail. Experimental results have shown that both the new working fluids have lower saturated vapor pressures, thereby indicating better energy release performances. Comparisons between energy consumptions to produce unit refrigerant at different source temperatures suggest that the two working fluids and Li Br/H2 O are all suitable working pairs for absorption energy storage/release systems, especially for those driven by low temperature waste heat with the heat resource temperature ranging from 380 K to 400 K.
