构建了一个管道系统回路，以模拟家庭、强制通风、供暖系统，以测试自然产生的空气微生物和带尖峰的阴沟肠杆菌细胞的传播。三种常见的炉装加湿器在受控的炉腔温度和气流下运行90天。收集了空气样本，但没有发现在实验条件下来自加湿器的生物体传播证据。关键词:加湿器、颗粒物、微生物学、测量、空气污染、实验、暖风、家用、住房。引文:研讨会，ASHRAE交易1993，第99卷，pt。1.

A ductwork loop was constructed to simulate a home, forced air, heating system in order to test the transmission of naturally-occurring, airborne micro-organisms and spiked enterobacter cloaceae cells. Three common types of furnace mount humidifiers were operated for 90 day periods under controlled furnace plenum temperature and airflow. Air samples were collected but no evidence was found of organism transmission originating from the humidifiers under the conditions of the experiment.KEYWORDS: humidifiers, particles, microbiology, measuring, air pollution, experiment, warm air heating, domestic, housing.
