Requirements for the size of the air inlet shaft in the generator room

For indoor installations, there are several key design practices that should be considered in the room design. First, create as much separation between intake air entry and discharge air exit planes in the building.

Provide emergency power to the controls associated with combustion air, ventilation air and other systems that must operate when the engine-generator is operating. Edit the specifications to include the EPS's maximum physical size, maximum allowable sound.

UTDOOR air enters a building through its air intake to provide ventilation air to building occupants. Likewise, building ex-haust systems remove air from a building and expel the contaminants to the atmosphere. If the intake or exhaust system is not well de-signed, contaminants from nearby out door sources (e.g., vehicle ex-.

• 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 generator or other driven equipment. A properly designed engine room ventilation system will maintain engine room air temperatures within 8.5 to 12.5°C (15 to 22 .

Internal air flows over the core and windings and is circulated by a shaft-driven fan. Heat is radiated through the enclosure. An external shaft-driven fan pushes ambient air over the cooling fins on the outside of the machine. Requires a larger machine due to the added losses associated with radiant cooling.

6 FAQs about [Requirements for the size of the air inlet shaft in the generator room]

What are the design requirements for a generator coolant outlet?

Regardless of the type of system installed at the generator site to cool the set, the following requirements and recommendation apply. The first design requirement is to limit the engine coolant outlet temperature to the “Maximum Top Tank Temperature” listed on the Generator Set Data Sheet.

How much incoming air does a generator need?

A generator typically needs 35-40% over-sizing of the incoming air based on the internal generator inlet air temperature being ambient + 20 degrees Celsius. For typical 32 degrees Celsius water, there is no de-rate for single-wall application. The generator requires this amount of air for cooling purposes. For example, for every kilowatt of loss, the required flow is 1 gallon per minute.

Does the genset equipment room need a ventilating system?

The genset equipment room will require a powered ventilating system. See Ventila-tion in this section for information on the volume of air required for proper ventilation. Since the engine of the genset does not have to mechanically drive a radiator fan, there may be additional kW capacity on the output of the genset.

How do I determine genset room airflow requirements?

Use the following method to determine the genset room airflow requirements. The engine and alternator will emit heat to the genset room. In Figure 6–43, this heat is labeled QGS. Consult the Generator Set Data Sheet to determine the amount of heat, as shown in Figure 6–44.

Why does a generator room need to be ventilated?

Ventilation of the generator room is necessary to remove the heat expelled from the engine, alternator and other heat generating equipment in the genset room, as well as to remove potentially dangerous exhaust fumes and to provide combustion air.

What are the requirements & standards for engine-generators?

This guideline defines the requirements and standards for design of engine-generators and associated system components. The guideline covers basic requirements for design, system components, controls, natural gas fuel systems, exhaust systems, automatic transfer switches (ATSs), room construction, outdoor enclosures and installation.
