TEGOLATORE DI COMANDO DELL'ARIA IN IMPIANTI DI CONDIZIONAMENTO

摘要

Air control regulators include automatically operated air curtains in which pressure and volume vary depending upon demand. A lever and fulcrum principle is used in this controller with the fulcrum position being variable. The fulcrum position can be adjusted manually or mechanically over a wide range of positions for each size of regulator and this variable location of the fulcrum varies the air flow rate through the regulator by re-positioning the flexible air curtain assembly within the regulator.
