1.5. NATURAL VENTILATION
Natural ventilation is the most simple and commonly used.
It is created by convection and is sufficient if no thermal
overload is expected, i.e. for units with small drive motors,
for intermittent operation or in moderate climates this is the
ideal method of cooling the compressor unit.
The inlet and outlet air openings are dependent on:
- the power of the electric motor
- the height difference between air intake and outlet
openings
- the air volume of the compressor room.
