| When studying a longitudinal ventilation system, the method to evaluate the capacity of the system is basically the same both in service and fire situation, with the exception of the chimney effect and the phenomena of thermal transfer which it?s the responsible of the changes in the air density which will be no longer constant. This thermal transfer concerns all the effects of the balance equation, but it is of a special importance for the jet fans that will have to offset the existing losses along the whole tunnel; and which performance will be decrease due to the temperature?s increase of the air. The aim of this chapter is to present a simplified one-dimensional method to estimate the sizing of a longitudinal ventilation system based on jet fans, which could be of help for designers or educational purposes. | |
