AIR HEATING IN CENTRIFUGAL FANS – RESEARCH AND ANALYSIS

The work is devoted to the study of a centrifugal fan and the aerodynamic heating of the air in the flow part of the fan. An overview of the basic theoretical and practical approaches to determining the air heating in a fan is made. Studies have been carried out on a medium-pressure centrifugal fan with various methods of regulating it and their effect on air heating.
