本文针对内燃机冷热电联供系统缸套水低品位余热无法高效回收利用的难题,利用缸套水低品位余热驱动LiCl溶液吸收式除湿机组,搭建实验平台,改变内燃机输出功率,研究LiCl溶液吸收式除湿机组性能变化情况.内燃机输出功率从18 kW增加到50 kW,内燃机缸套水热负荷增加,再生器的再生能力增强,再生液脱水量△mg从0.84 g/s升高到1.02 g/kg,再生液浓度从33.3%升高到34.0%;除湿器的性能增强,送风温度从21.1℃升高到22.5℃,相对湿度从49.49%降低到41.97%,溶液的除湿量从0.69 g/s增加到0.76 g/s.
Low temperature waste heat of CCHP internal combustion engine jacket water cannot be efficient recycled,so low temperature waste heat of jacket water was considered to use driving LiCl solution absorption dehumidification unit.Experimental platform was built.Changing the engine output power,LiCl solution dehumidification unit performance had been researched.Engine output power increased from 18 kW to 50 kW,the heat load of engine jacket water increased,regenerative capacity of regenerator enhanced,dehydration amount △mg increased from 0.84 g/s to 1.02 g/kg,renewable liquid solubility increased from 33.3% to 34.0%.Dehumidifier performance was better,air temperature increased from 21.1℃ to 22.5℃,relative humidity reduced from 49.49% to 41.97%,the amount of desiccant increased from 0.69 g/s to 0.76 g/s.
