Industrial ventilation and air conditioning systems aim to ensure the conditions of air purity and microclimate corresponding to the activity of man and the nature of the technological process. The parameters of the state of the air which are of interest for the technique of ventilation and air conditioning are: air temperature and humidity, atmospheric pressure, and air speed. For the study on the variation of the air state parameters inside the industrial ventilation installations, in the experiment laboratory, on the study of the industrial ventilation systems, the experiment was performed on the variation of the air state parameters in the conditions of circulation through the ventilation duct a quantity of carbon monoxide at constant pressure. Prior to the introduction of carbon monoxide into the piping, the ventilation system was started at nominal parameters. During the experiment, the operating parameters of the drive motor were changed using a frequency converter on levels 50; 40; 30; 20; 10 and 5 Hz. The ventilation system used was structured by means of flow converters which were fixed in the open position. The ventilation system as well as the flow variators were operated by the SCADA type command and control system. The paper will present the analysis of the variation of state parameters (temperature, humidity, absolute pressure, and air speed) by introducing a constant amount of carbon monoxide in the ventilation duct.
