摘要
以空调系统运行前后室内空气微生物为研究对象,考察肺炎链球菌和青霉菌在不同相对湿度和湿处理时间条件下的存活状况。研究结果表明:空调系统对室内空气微生物污染会产生加重效应;降低相对湿度能够有效抑制肺炎链球菌和青霉菌的存活。通过Origin软件的数据拟合,建立空调系统微生物(肺炎链球菌和青霉菌)在一定相对湿度(50%)条件下的失活动力学模型,该模型为空调系统室内空气微生物污染研究提供重要的理论基础。
Taking indoor air microorganisms at the beginning and end of air-conditioning system running as study object,the survival situations of pneumococcal and penicillium are investigated under different relative humidity and wet-processing time conditions.The study results show that the air-conditioning system can aggravate the indoor air microbial pollution;decreasing the indoor air relative humidity can restrain the survival of pneumococcal and penicillium greatly.Through data fitting using Origin software,the dynamics models of microorganisms（pneumococcal and penicillium）inactivation under a certain relative humidity（50%）are built up,which provides an important theoretical basis for the research of indoor air microorganisms under air-conditioning system.
