| Title of the article | Design characteristics of direct action airflow stabilizer with nonlinear stiffness of elastic element, included in the natural exhaust system |
| Abstract. | Problem statement. Natural exhaust systems are widely used in various types of buildings. With decreasing temperature, natural exhaust flow rate increases more than the predicted, which is accompanied by an increase spending of heat for heating the outside air. Stabilization of airflow and the elimination of useless spending of heat in the cold period of the year is an actual problem. The aim of the study is to determine the design characteristics of a stabilizing device proposed in the author’s patent, with an elastic element having the necessary nonlinear stiffness, made of spring steel, included in a natural exhaust ventilation system. Results. The main results of the research consist in analytically obtained characteristics of a direct- action airflow stabilizer with an elastic element having a given nonlinear stiffness characteristic. The adopted parameters of the elastic element of the device provide sufficient stabilization of airflow with a small initial pressure loss. Conclusions. The significance of the results obtained for the construction industry is that such a device is able to stabilize the airflow of natural exhaust in a wide range of outdoor temperatures, applicable to most floors of multi-storey buildings. The use of such flow stabilizers in natural exhaust systems saves thermal energy in the cold period of the year and contributes to a better microclimate in the premises. |
