摘要
通过对具有冷却壁面的下送风系统中室内空气的温度变化进行实验研究,分析讨论了在一定热源强度和送风条件下,因冷却壁面导致的下降流的空气温度场和气流分布。实验结果表明：冷却壁面温度越低,下降流越剧烈,产生的范围就越大；由于下降流破坏了室内气流组织,从而导致空气质量的恶化。
Based on the temperature variety in the underfloor air supply system for cooling wall, analyzed the temperature field and the air flow distribution caused by the descent of air flow for the cooling wall on certain hot source strength and air supply condition. The experiment expresses as a result： the lower the temperature of the cooling wall, the more violent air flow descends. The descent of air flow for the cooling wall is unfavourable to air flow distribution and air quality.
