THE DIFFUSER FOR VARIABLE AIR VOLUME SYSTEM

摘要

PURPOSE: A diffuser with an electric air volume control cone is provided to prevent heat loss and maintain indoor temperature by indoor temperature since a lower air supply hole is precisely opened and closed. CONSTITUTION: A diffuser comprises a main body(30) and a pick-up cone(40). The main body is coupled with an air supply hole(11) and an air-duct(20) of a ceiling(10). The pick-up cone is formed on the opened lower part of the main body and controls the volume of supplied air. The pick-up cone is formed to move up and down by a motor based on the main body. A motor(50) having the motor shaft(51) is fixed inside the main body by a bracket(60). A support(70) having a conveying groove(71) is formed so that the motor shaft can pass through the lower part of bracket.
