摘　　要：为了实现高能量密度/功率密度的储热/储冷,本文采用沸石13X-水为吸附工质对设计构建了一台基于低压吸附诱导水闪蒸的高功率吸附热池储冷样机,储冷阶段利用高温循环水驱动沸石13X脱附,供冷阶段利用沸石13X的低压吸附作用诱导水低温闪蒸实现冷量输出。实验结果表明:该系统在制冷前14 min内,制冷功率可保持在20kW及以上,最大制冷功率达23.45 kW,系统最大单位质量吸附剂制冷功率(SCP)可达321.2 W/kg,空冷器进出口空气温差在制冷前3 min到12.8 min内保持在10℃及以上,当吸附床吸附水蒸气的平均速率为71g/min时,系统在开始制冷后近36 min内能够保持10.4 kW的稳定制冷量。In order to achieve high energy density/power density heat storage/cold storage,zeolite 13X-water was used as the adsorption working medium to build a high-power adsorption cold storage system based on low-pressure adsorption induced water flash in this paper.In the heat storage period,zeolite 13X desorption process is forced by high temperature circulating water.In the cooling release stage,the adsorption of zeolite 13X is used to induce low-pressure flash evaporation to achieve refrigeration output.The experimental results prove that the cooling power of the system can be maintained at the level of 20 kW and above within 14 minutes after refrigeration.Meanwhile,the maximum cooling power and specific cooling power(SCP)can reach to 23.45 kW and 321.2 W/kg respectively.The air temperature difference between inlet and outlet of the air cooler is maintained above 10℃ within 3 minutes to 12.8 minutes after refrigeration,with a maximum temperature difference of 10.4℃ during the refrigeration process.When the average rate of water evaporation is 71 g/min,the system can maintain a steady cooling capacity of 10.4 kW for nearly 36 minutes.
