- The results show that : the lose of pressure is small when air velocity and the longth of honeycomb potter heat storage bed are varied ; but the switch time of air and the bulk of storage bed play important roles as regard its dynamic thermal performance
结果表明：蜂窝型陶瓷蓄热体换热器的压力损失随着空气流速以及蓄热体长度的不同而变化，但总体上说，其压力损失并不大；四通换向阀的换向周期和蜂窝陶瓷蓄热体换热器的体积等是影响其温度效率和热回收率等热性能的重要因素。
