Influence of thermodynamic properties of air storage chamber on the performance of AA-CAES
摘要
Abstract
Air storage chamber is the main gas storage device in the AA-CAES,and its properties have important impact on the variation of the air temperature and pressure. To describe the thermal variation of air during the operation process and accurately explore the influence of the thermodynamic properties on the system performance,a model of diabatic storage chamber with constant wall temperature was established in this paper. The results show that the designed chamber had the energy storage efficiency of 0.58 and has the energy storage density of 1.59kW·h/m3. The overall performance of the air storage chamber in the operation process is exothermic. Highest energy storage efficiency was obtained with the adiabatic model,and the energy storage density reached maximal under the constant temperature model. However the system performance parameters were lower in the actual operation,so the thermal properties of the air storage chamber need to be optimized. The energy storage efficiency can be improved by increasing the amount of energy storage and power released. It was found that the change of storage power had greater effect on storage efficiency.关键词
