摘要
通道轮式新风换气机在严寒地区冬季运行时,其室外排风侧结霜是影响其应用和发展的主要问题。文中通过对霜形成机理的分析,建立了通道轮式新风换气机的核心部件通道轮式换热器的结霜模型。分析了不同工况下室内排风的温度、相对湿度以及室外新风温度对结霜的影响,得到了结霜量的变化规律。
Freezing on the surface of exhaust outlet is a major problem effecting the application and development of the channels wheel fresh air ventilator. From the analysis of freezing mechanism, a mathematical model was established for the exhaust outlet of the channels wheel fresh air ventilator. By simulating and analyzing the influence of the temperature and relative humidity of indoor air, the temperature of outdoor air on freezing growth and the laws governing freezing growth were simulated. Suggestions were made on how to anaalyze the performance of the channels wheel fresh air ventilator with freezing.
