摘　　要：介绍了柴油发电机组的几种换热方式与发热量的构成。强调了采用通风降温时,换热器的热风不能排入机房,应直接排入排风道,再由耐高温风机排至室外。通过实例说明了这种降温方式最小进排风量的计算方法。介绍了目前工程中存在的几个共性问题,并提出了解决方法。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.
