5.4.1. Ventilation Recommendations
To help ensure proper ventilation, observe the following recommendations:
Air inlets should be located away from all ancillary equipment heat sources.
Enclosure/electronics exhaust must be vented to a location where it will not be re-
ingested or ingested by other systems.
Engine exhaust must be vented to a location where it will not be re-ingested or ingested
by other systems or present a suffocation hazard to personnel.
Make provisions for condensation prevention on engine exhaust ducting, including sloping
ducting, drip legs, etc., per local mechanical codes.
5.4.1.1. Indoor Installations
The pressure drop within the room should not exceed 249 Pa (1 inch WC) under all
operating conditions. Forced ventilation may be required to ensure pressure drop
requirements are met.
Package exhaust vented into a room will increase room temperature, which will derate
the microturbine and reduce the cooling of the electronics. Extraction fans with
thermostat controls can be used to remove enclosure/electronics exhaust.
Ventilation should eliminate hot air dead spots, where air movement is not uniform.
Insulating the engine exhaust ducts decreases heat transfer to the room air hence
decreasing the ambient room air temperature.
The impact of exhaust ducting on backpressure must also be considered. If the distance
is greater or the duct size is different, backpressure at the microturbine exhaust can
increase, thus reducing the allowable backpressure available for ducting after the HRM.
Adequate lighting should be provided for proper operation and maintenance of the
equipment.
