Fig. 10.7: Artificial ventilation of a compressor room with a
sound-insulated BOGE screw-type compressor | In many cases natural ventilation of the installation room is insufficient. Due to structural aspects or the high output of the installed compressor the flow of cooling air is inadequate for the task. In these cases, the hot air must be extracted with the aid of a ventilator.
Artificial ventilation increases the flow speed of cooling air inside the installation room and guarantees the required flow of air by forced ventilation. There are greater reserves when outside temperatures are high. The inlet air aperture must be modified to cater for the ventilator output.
The ventilator(s) should, for reasons of economy, be controlled in several stages by a thermostat. The control depends on the temperature in the installation room. The higher the temperature rises, the greater the output rate of the ventilator. |
