Abstract

Inventia se refera la un ventilator radial mono si dublu aspirant, silentios, folosit în mod curent în instalatiile de ventilare sau conditionare. Ventilatorul radial, monoaspirant si dublu - aspirant, compus dintr-un rotor cu palete curbate înainte,montat într-o carcasa spirala, prevazuta cu o gura de refulare ce poate fi obturata cu ajutorul unei placi, caracterizat prin aceea ca, în scopul cresterii randamentului, placa obtureaza gura de refulare pe o distanta si este pozitionata fata de per iferia rotorului la o distanta radiala, marimile satisfacînd relatiile.The invention relates to a mono and double aspirating, silent fan, currently used in ventilation or conditioning installations. The radial, single-aspirating and double-aspirating fan, consisting of a pre-curved blade rotor, mounted in a spiral housing, provided with a discharge opening which can be obstructed by means of a plate, characterized in that, in order to increase the yield , the plate obstructs the discharge hole over a distance and is positioned relative to the rotor periphery at a radial distance, the sizes satisfying the relationships.
