Generator inlet and outlet air temperature installation location

Locate air inlet, ventilation and air outlet openings in a structure so that already exhausted air will not be drawn back into the building. Louvers, screening, expanded metal and other materials used to cover air openings are a restriction to air flow.

generator air intake. Alternatively, custom generators can be sized to handle specific ambient conditions. In larger multiple engine sites, the normal 8.5 to 12.5°C (15 to 22.5°F) temperature rise guidelines for engine rooms may require unobtainable or uncomfortable air velocities. For these larger sites, a ventilation system needs to give.

Piping Components - The inlet and outlet ports for the Parker Balston Zero Air Generator are 1/4” NPT (female) and located on right side of the unit. Inlet tubing and fittings should be clean and rated for 125.

The 3/8” female NPT inlet and outlet ports are located on the right side of the generator (see Figure 1). Inlet tubing and fittings should be clean and rated for 125 psig minimally. A manual shut-off valve and pressure regulator should be installed directly upstream from the generator inlet port.

6 FAQs about [Generator inlet and outlet air temperature installation location]

Where should genset room airflow be located?

Outlet should be located on downwind side of the building. Additional combustion equipment should not be located in the genset room. (See Negative Pressure in the Generator Set Room, page 6–75.) Use the following method to determine the genset room airflow requirements. The engine and alternator will emit heat to the genset room.

How do I allow airflow across a genset?

Permit airflow across entire genset from alternator end to radiator end. (See Inlet and Outlet Design Guidelines, page 6–75.) Draw/discharge ventilation air directly from/to outdoors. (See Inlet and Outlet Design Guidelines, page 6–75.)

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 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.

How can a generator set be simulated?

Generator sets must be properly installed to ensure that cooling air is not restricted or artificially heated by nearby heat sources or from recirculation. Fortunately, installation influences can be simulated using software called Computational Fluid Dynamics. CFD is a software tool used to predict fluid flow, including thermal influences.

Should genset room operating temperature be close to outdoor temperature?

Designers should be aware that the genset room operating temperature will be very close to the outdoor temperature, and either not route water piping through the genset room, or protect it from freezing. As ventilating air flows through an equipment room, it gradually increases in temperature, particularly as it moves across the genset.
