Ventilation and cooling design of underground diesel generator rooms

Presents several heat exchanging modes of the diesel generator room and the composition of heat release. Emphasizes that hot air from heat exchanger should be taken into air chute, not into generator room, and then to be discharged outdoor by a high temperature resistant fan when the generator is cooled by ventilation. Presents the computational method of the minimum intake and exhaust air rate with an example, and puts forward some common existed problems in projects and their solutions.
