摘　　要：本文基于雷诺平均的n-s方程和RNG的k-着方程,采用数值模拟方法,分别对同一住宅在单独运行空调系统时与组合通风和空调系统联合运行时的室内空气质量进行了研究。研究结果表明,空调系统与组合通风系统联合运行对降低室内污染物浓度,提高室内空气质量具有较好的效果。Indoor air quality is studied using numerical simulation method based on the Reynolds averaged n-s equations and the RNG κ-ε equations under varying conditions of only running air conditioning system and running combined ventilation system and air conditioning system together in the same room. The results show that running combined ventilation system and air conditioning system together has preferable effect on decreasing indoor contamination concentration and improving indoor air quality.
