2.2 Air and Cooling
Combustion and heat dissipation require an ample flow
of clean, cool air.
To prevent accumulation of explosive gases, ventilate
compartments containing batteries.
2.2.1
Installation Considerations
Intake and outlet openings. Provide air intake and air
outlet openings for generator sets located in a building
or enclosure. Keep air inlets and outlets clean and
unobstructed. Position the air inlet into the prevailing
wind and the air outlet in the opposite direction.
Ventilating fans. Use ventilating fans and/or ductwork
to increase airflow if the generator set's cooling fan does
not provide adequate cooling to prevent overheating.
See Figure 2-2. When using ductwork and ventilating
fans, check the exhaust fan capacity in m
using exhaust fans, install fan-operated louvers with
exhaust fans to regulate airflow. See Figure 2-5. Follow
the fan manufacturer's recommendations to determine
the size of the inlet and outlet openings.
Figure 2-2 Ventilating Fans
Thermostatically-controlled louvers. The ventilation
system must provide a temperature differential sufficient
to prevent high engine temperature shutdown on even
the hottest days.
In areas of great temperature variation, install movable
louvers to thermostatically regulate airflow and room
temperature. See Figure 2-3 and Figure 2-4. Refer to
2.2.2, Cooling Air Requirements, Louvers, for further
information.
