创新的模块化吸附和再吸收热电池用于冷热电联供。在复合吸附剂的开发中，选择了经硫酸处理的膨胀天然石墨，以改善传热和传质性能。结果表明，该材料的热导率和磁导率分别为11.9 W m− 1 K − 1 ~ 36.5 W m− 1 K − 1和1.04 × 10− 14 m2 ~ 8.02 × 10− 11 m2。研究了复合吸附剂的吸附特性。结果表明，当热源温度为130-150 °C，蒸发温度为−20 °C ~ 5 °C时，MnCl 2-CaCl 2-NH3体系的吸附性能最好。吸附和再吸收工作对的吸附量范围为0.169 kg kg− 1至0.499 kg kg−1。根据测试结果，对模块化吸收式热电池和吸附式热电池的能量密度和功率密度进行了比较。结果表明，热密度范围从580 kJ kg− 1到1368 kJ kg− 1，而冷密度范围从400 kJ kg− 1到1134 kJ kg−1。同时，热和冷功率密度范围从322 W kg− 1到1502 W kg− 1和从222 W kg− 1到946 W kg−1。吸附式和再吸收式热电池各有优点，可灵活连接，适用于规模化应用。
Innovative modular sorption and resorption thermal cell are presented for cold and heat cogeneration. Expanded natural graphite treated with sulfuric acid is selected in the development of composite sorbents for improved heat and mass transfer performance. It is indicated that thermal conductivity and permeability range from 11.9 W m−1K−1to 36.5 W m−1K−1and from 1.04 × 10−14m2to 8.02 × 10−11m2. Sorption characteristics of composite sorbents are also investigated. Results demonstrate that MnCl2-CaCl2-NH3reveals the best sorption performance under the condition of 130–150 °C heat source temperature and −20 °C to 5 °C evaporation temperature. Sorption quantities of sorption and resorption working pairs range from 0.169 kg kg−1to 0.499 kg kg−1. Based on testing results, energy density and power density of modular resorption thermal cell are compared with that of sorption thermal cell. Results indicate that heat density ranges from 580 kJ kg−1to 1368 kJ kg−1whereas cold density ranges from 400 kJ kg−1to 1134 kJ kg−1. Simultaneously, heat and cold power density range from 322 W kg−1to 1502 W kg−1and from 222 W kg−1to 946 W kg−1. Both sorption and resorption thermal cell have their own advantages, which are flexible connected for scaling applications.
