About 1.5 meters.
The air inlet louvers of the generator room need to be about 1.5 meters above the ground. Their function is to prevent direct radiation from the sun to the instrument and reflected radiation from the ground to the instrument, and protect the instrument from strong wind, rain, It can avoid the influence of snow, etc., and ensure that the sensing part of the instrument is properly ventilated, so that it can truly sense changes in outside air temperature and humidity.
The air inlet louvers can remove the heat generated in the computer room through the circulation of air, and can also prevent some small animals from entering the computer room.

1. Manufacturer’s requirements for smoke exhaust pipe wells (mandatory) Minimum clearance size: 800x800mm for one generator; 1200x1200mm for two generators. Increase appropriately when conditions permit.
2. Regarding the clearance size of the spray dust removal room (suitable to be installed): 1800x2000mm when one generator is used; 1800x2800mm when two generators are used together.
Diesel generator room ventilation includes two parts, daily ventilation and working ventilation.
Daily ventilation: The number of daily ventilation in the machine room of air-cooled and water-cooled generators is 6 times, and the number of ventilation in the oil storage room is not less than 3 times. For computer rooms that use gas fire extinguishing systems, after a fire, this ventilation system is responsible for removing indoor exhaust gas, but it is not accident ventilation. To ensure people's safety, it is recommended to set the start button for accident ventilation.
Working ventilation: Water-cooled diesel generators must consider the amount of air required for working oxygen consumption; air-cooled generators have a large cooling air volume and generally use natural air intake. Diesel engines have their own fan pressure emissions, but diesel generators The pressure head of the built-in fan is only about 150Pa. When the resistance of the shaft is large, a fan needs to be added to overcome the resistance of the shaft. Generally, if the resistance of the air inlet shaft is large, an air inlet fan is added; if the resistance of the exhaust shaft is large, an exhaust fan is added.
The diesel generator room uses gas fire extinguishing. 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 started, these valves will be closed in a chain to ensure the fire extinguishing effect.
The exhaust of diesel generators is pressurized exhaust with high flue gas temperature and high air flow velocity. The flue gas needs to be discharged at high altitude. The smoke pipe should be thermally insulated and a shock-absorbing hanger should be installed.
Diesel generator rooms must pay attention to ventilation and smoke exhaust, otherwise it will affect the use of the generator and cause damage to the generator. For companies that cannot afford power outages, damage to the generator is a very bad thing. matter.
