In actual use, many users do not pay attention to the working environment of the diesel generator set, resulting in low efficiency of the unit operation, and no reason can be found. In fact, the engine room must have sufficient air flow to meet the needs of combustion and cooling ventilation of the unit. Therefore, the cooling and ventilation of the diesel generator set is very important. Today, Starlight will introduce the cooling and ventilation requirements of the diesel generator set.

1, cooling requirements

  1) When installing the unit, the radiator should be as close as possible to the exhaust vent to prevent the recirculation of hot air. When there is no air duct, it is recommended that the distance between the radiator and the air outlet is not more than 150 mm; if the equipment room is difficult to meet the above requirements, it is recommended to install the corresponding air duct.

  2) The area of ??the exhaust vent should be 1.5 times the air discharge area of ??the radiator. Usually, the air duct and the exhaust louver are installed with the radiator.

  3) The bending of the duct should pass through the appropriate elbow. If the pipeline is too long, the size should be increased to reduce the exhaust back pressure. Long-distance air duct mufflers should be specially designed according to the characteristics of the building.

  4) The entrance and exhaust vents of buildings are usually equipped with louvers and grids. When calculating the size of the vents, the effective ventilation area of ??the louvers and grids should be considered.
