Study on High Power Sorption Battery Pool Cold Storage System Based on Zeolite and Water as Working Medium Pair
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.
