Residential generator room air shaft area

Where should a generator room be located?

Locating the room above the lowest level of the building is preferred. Separate the generator room from occupied areas or provide sound-proofing and vibration isolation so the EPS will have minimal impact on surrounding areas. Generator room designs should maintain the sound criteria of the surrounding areas.

Where should exhaust air be sourced for a generator?

For generators with remote radiators, it is recommended that the exhaust air should be sourced as high as possible and directly above the generator sets. Significant bypass of ventilation airflow directly into the discharge airflow will lead to reduction in cooling effectiveness and elevated temperatures within the room.

Where should a generator air duct be placed?

The air should flow over the entire generator horizontally, thereby cooling the alternator and effectively purging internal heat. As for the exhaust fans, they should be placed high and directly above the generator to extract heat and undesirable emissions. Air Duct: Duct systems are likely to require multiple turns.

What makes a good generator room?

A well-designed generator room will ensure that: Recirculation and bypass airflow is minimized; noise and vibration within and outside the building complies with code requirements, and ancillary components external to the generator set operate reliably.

What temperature should a generator room be?

It must be equipped with automatic sensing for auto-start. What should be the temperature in the generator room? The generator’s room temperature must be maintained at 18 to 27 degrees Celsius with 40 to 60% of relative humidity. Share This Story, Choose Your Platform!

Why does de-rating become steeper in a generator room?

De-rating becomes steeper for room temperatures above 122 F. High generator-room temperatures also necessitate de-rating of electrical equipment and components that typically are located within the generator room, such as transformers, switchgear, and electrical feeders.
