摘　　要：人工实验环境室主要应用于家电产品的能效检测,需满足高精度恒温恒湿的环境控制要求及风速要求。依据国家家电能效检测环境要求对环境室进行送风结构设计,确定了3种不同风量下的局部送风孔板模式,并以局部孔板上送侧回的方式基于CFD仿真对于实验环境室进行了气流组织及温度场的模拟。基于理论研究设计建造了人工实验环境室并进行了实验研究,在工况温度稳定后进行温度分布均匀性测试。试验结果表明:4600 m^(3)/h风量送风可用于工况的快速调节,3700 m^(3)/h风量送风可用于实际家电性能测试以降低噪声,噪声为58.4 dB(A),噪声值降低6.7dB(A),区域间最大偏差0.36℃。模型模拟计算结果与试验测量值吻合度高,对环境室内的气流组织优化设计具有指导意义。The artificial experimental environment room can be applied to the energy efficiency test of household appliances,and has high-precision control requirements for the constant temperature and humidity environment and wind speed requirements.According to the national environmental requirements for energy efficiency test of household appliances,the air supply structures were designed.The local air supply orifice mode under three different air volumes was determined,and the air distribution and temperature field of the experimental environment room were simulated by CFD software according to the top supply and side return mode of local orifice.An artificial experimental environment room was designed and constructed based on the theoretical study and experimental study was carried out.And the temperature distribution uniformity test was carried out after the working condition temperature became stable.The experimental results show that the 4600 m^(3)/h way of air supply can be used for rapid adjustment of working conditions.To reduce noise,the 3700 m^(3)/h way of air supply can be used for performance test and the noise of actual household appliances to reduce the noise.The noise is 58.4 dB(A)with reduction of 6.7 dB(A),and the maximum deviation between regions is 0.36℃.The simulation results are in high agreement with the experimental results,which can provide guidance for optimization design of indoor air distribution.
