Generator Room Design Requirements

Design of an engine room ventilation system.

Generator room design requirements.

Some driven equipment such as a generator in a large engine installation may require a dedicated ventilation source. Generator sets are accessible manufacturer and code required clearances are maintained major components can be removed and replaced clean and relatively cool air can circulate around the generator set ventilation airflow room inlet airflow is. The inlet shutter is generally located at the rear end of the generator and the exhaust shutter is located at the position corresponding to the inlet shutter. The magnitude of de rating varies with manufacturers generator set capacity engine fuel type and more.

The room in which the generator is loctaed must have a two hour fire rating addressed by the ventilation system. Generator room temperatures in excess of 104 f typically require de rating of the generator set and potential upsizing of components to support the design electrical load. June 19 2017 size. Installations over 600 volts.

A maximum 11 c 20 f room temperature rise above ambient shall be utilized in designing the ventilation air system. Generator room size requirements date. Installations over 600 volts require even wider aisle space from 3 feet 1 to as much as 12 feet 4m for voltages above 75kv. A minimum of three to four feet of aisle space is required depending on if.

Generator room design requirements optimize performance whether you operate an extensive data center or a mobile construction site reliable power is imperative to your business operations. A well designed generator room will ensure that. It is also important to consider all engine room equipment in the design of a ventilation system and provide a comfortable environment for service personnel to perform maintenance. Since the generator room is generally on the first underground floor there should be a large enough exhaust vertical which is beneficial to noise elimination.

For generators located indoors ventilation must be considered heat from engine radiator alternator and exhaust system must be vented to atmosphere to obtain proper room temperature. When it comes time to purchase a new used generator it s essential to consider where your power source will live and operate. Installations of 600 volts or less.

Service rooms with 1 200 amps or more require two exits in case of fire or arcing.
