绕片式冷风机霜层分布的理论计算

The Computer Simulation of Unit Cooler’s Performance and Evaluation of Frost Distribution

利用计算机模拟冷风机在冷藏库中的实际运行工况，从理论上计算了霜层在冷风机翅片上的分布及生长规律和冷风机风量及压降随时间的变化规律，并和实测值作了比较。

The regularities of frost growth and distribution along fin pipes and the changes of air flow rate and pressure drop through fin pipes were obtained by computer’s simulating the practical operating conditions of unitcooler.These results are in correspondence with the experimental ones.So much convenience can be gained by using the program to optimize the unit cooler’s configuration in the future.
