摘要
理论计算了在热压作用下冷库门冷风量的渗透情况。建立了相应的数学模型,用CFD软件模拟了在热压作用下冷库门的气体流动,比较了计算值和模拟值的大小。最后得知在热压作用下冷库门处库外气体和库内气体存在着质量交换,有必要在冷库门加装空气幕以减少库内、外热湿交换。
The infiltration of cold capacity at cold-storage door under thermal pressure is calculated theoretically. The mathematical model is set up and the velocity of air flow is simulated with CFD software. The calculated value is compared with simulated value. The results show that gas exchange at the gate is quite large under thermal pressure. Therefore it is necessary to install air curtain at cold-storage door for preventing heat and mass transfer through the gate.
