摘要：The problem of industrial ventilation has arisen as a result of the serious pollution problems of both the industrial areas and the industrial premises. The polluted atmosphere, outside the industrial premises, can penetrate inside them naturally or through ventilation systems. The commissioning of a ventilation system occurs whenever a workplace generates more pollutants than those normally accepted by hygiene of work conditions, safety, health, etc. In order to be able to choose the correct ventilation system, a complete analysis of the workplace to be ventilated must be carried out so that the solution chosen to solve the problem of the exhaust, but also be well received by the user, respecting the thermal comfort of it. The paper presents the results of experimenting with a balanced tandem ventilation system with stable and unstable operation.
