Diesel generator room ventilation includes two parts: daily ventilation and working ventilation.
Daily ventilation: the number of ventilations in the engine room of air-cooled and water-cooled generators should be 6 times, and the number of ventilations in the oil storage room should not be less than 3 times. For computer rooms that use gas fire suppression systems, after a fire, this ventilation system is responsible for exhausting indoor exhaust gases, but it is not accidental ventilation. To ensure personal safety, it is recommended to set the start button for accidental ventilation.
Working ventilation: Water-cooled diesel generators must consider the amount of air required for oxygen consumption in operation; air-cooled generators have a large volumee cooling air and generally use a natural air intake. Diesel engines have their own fan. pressure emissions, but diesel generators The pressure height of the built-in fan is only about 150 Pa. When the shaft resistance is large, a fan should be added to overcome the shaft resistance. the air inlet shaft is large, an air inlet fan is added; if the exhaust shaft resistance is large, an exhaust fan is added.
The diesel generator room uses a gas fire extinguishing system. Solenoid valves should be installed on the air inlet and exhaust channels. When a fire occurs in the diesel generator room and gas fire extinguishing is triggered, these valves will be closed. in a chain to ensure the extinguishing effect.
Diesel generator exhaust is a pressurized exhaust with a high temperaturehigh combustion gas ratio and high air flow speed. Combustion gases must be vented at high altitude. The flue must be thermally insulated and equipped with a shock-absorbing support. should be installed.
Diesel generator rooms should pay attention to ventilation and smoke exhaust, otherwise it will affect the use of the generator and cause damage to the generator. For businesses that cannot afford power outages, generator damage is very serious. bad thing.
Should the diesel generator fuel tank storage area in the power distribution room be equipped with exhaust ventilation?
General ventilation and the supply of process air into the diesel engine room is carried out by HVAC professionals. Others are determined by electrical major. To put it simply: when the rooms diesel machines do not produce electricity, the air supply and exhaust is provided by HVAC professionals and when the machines in the diesel engine room are operating, the process air supply is also ensured at that time by the HVAC department; . As with process smoke extraction, these are determined by the electrical sector.
I don't understand, why is there a diesel generator tank in the power distribution room?
The oil storage room of the diesel generator requires exhaust gas, and the number of air changes can be 6 times; the diesel generator room should take into account the heat rejection, harmful substances, etc., and consider the exhaust gas according to different At the same time, the exhaust gas and combustion of diesel require l oxygen, so additional air should be considered accordingly to avoid affectingr normal combustion.
