How The Diesel Generator Set Cooling And Ventilation of Work?

Jan. 28, 2022

Do you know how the cooling and ventilation systems of diesel generator sets work with each other? In cold climates, adjustable shutters can be installed at the inlet and exhaust ports of standby and rarely running generator sets. The shutters can be colsed when the diesel generator set is not running. Standard thermostatically controlled invasive cooling water heaters are usually also installed for diesel generator sets that are automatically put into operation after mains failure. The cooling and ventilation information of the above diesel generator set is compiled and released by the diesel generator set manufacturer edition. Diesel generator sets should be installed the radiator as close as possible to the exhaust to prevent recirculation of hot air.

When there is no air duct, it is recommended that the distance between the radiator and the air outlet should not exceed 150 mm; if the equipment room cannot meet the above requirements, it is recommended to install the corresponding air duct. The area of the tuyere should be 1.5 times the exhaust area of the radiator. Under normal circumstances, it is necessary to install air ducts and exhaust shutters in conjunction with the radiator. The bending of the air duct should pass through an appropriate elbow, and the pipe should be enlarged to reduce the exhaust back pressure if the pipe is too long. Long-distance duct mufflers should be specially designed according to the characteristics of the building. Blinds and grids are usually installed at the air inlet and outlet of buildings. When calculating the size of the air outlet, the effective ventilation area of the blinds and grids should be considered.


Diesel generator sets require a lot of air for combustion and cooling, which is often overlooked. It is recommended that the total area of the air inlet should be at least twice the area of the unit's radiator; all air outlets should be able to prevent the entry of rainwater. In cold climate regions, the intake and exhaust vents of standby and rarely operating diesel generator sets can be fitted with adjustable shutters, which can be closed when the unit is not running. Standard thermostatically controlled invasive cooling water heaters are usually also installed for diesel generator sets that are automatically put into operation after mains failure.
