What Are Fresh Air Intake Louvers? Fresh air intake louvers are designed to let fresh air into a building while keeping out the things you don''t want like rain, snow, or dirt. They''re made up of
This document provides calculations for sizing ventilation requirements for a generator room and transformer room. It calculates heat loads, required airflow, and intake/exhaust area sizes for different equipment configurations including
• Cool air to the air cleaner inlet. • Cool air to the torsional vibration damper. • Habitable temperatures for the engine operator or service personnel. • Cooling air for the
packaged HVAC unit or a building. Outside air is brought in through an air intake louver. If not part of a packaged unit, these louvers and grilles may be on or in the roofs, in stacks, in the
be on the upper side of the wall and the air inlet should be on the lower side. In the cold area, attention should be paid to the influence of the air inlet and the air outlet on the temperature of
• Air intake louvers to ventilate the generator room shall be sized to accommodate the amount of combustion air needed by the engine, the amount of cooling air that flows to the radiator and
The generator intake requires cool, clean air. Proper airflow ensures safe and ideal working conditions for maintenance personnel and other employees. Generator louvers help solve both
The calculations determine the ventilating air needed based on the total heat radiation of the engine and generator and engine combustion air. It also calculates the intake louver size needed based on the total air quantity and an
The most common device used to muffle noise from generators is acoustical enclosures. Typical sound attenuated generator enclosures consist of panels that are multi-layered composite treatments comprising of an impervious exterior
Preferably, the source of ventilation air should be as low as possible and the air should flow over the entire generator set, thereby cooling the alternator, engine block, and radiator (for sets with unit-mounted radiators) to remove the after-cooler and jacket-water heat.
Louvers should be fitted to the windows to protect the air outlets. The louver fins should have openings of sufficient dimensions to make sure that air circulation is not being blocked. Otherwise, the occurring backpressure might cause the genset to overheat.
Radiated heat is removed with approximately half the airflow of a horizontal flow system. It is important to stretch the air curtain inlet the full length of generator set. Special care must be used to ensure adequate cool airflow at the generator air intake and at the generator coupling.
Routing: The source of ventilation air should have a distant entry with the intake louvers positioned as low as possible. The air should flow over the entire generator horizontally, thereby cooling the alternator and effectively purging internal heat.
The most efficient method of removing this heat is with a system that pulls air past switchgear, then over the engine, from back to front. If air curtains are used, the airflow should gather this radiant heat just above the gen set, which offers greater efficiency and less exposure to high air velocities in other areas of the gen set room.
If air curtains are used, the airflow should gather this radiant heat just above the gen set, which offers greater efficiency and less exposure to high air velocities in other areas of the gen set room. Airflow should be upward around each engine or in the case of engines with mounted radiators, across the back of the engine to the front.
