BYPASS AIR VOLUME CONTROL METHOD AND UNIT

摘要

The present invention relates to a bypass air-volume control unit (8) and method that allows the adjustment of temperature of each separate zone (14) of a central air-conditioning system (11 ) without causing to pressure imbalances in the main air-transferring conduits (12, 13), wherein air, which is to be controlled by an outer frame means (1 ) that is connected to the central (1 ) by means of a blowing inlet conduit (5.1), a return air outlet conduit (5.2), and to such zone (14) by means of a blowing air outlet conduit (5.3) and a return air inlet conduit (5.4), is taken to a closed zone; and such air taken in through said inlet conduits (5.1 , 5.4) is directed to said outlet conduits (5.2, 5.3) by means of a flap (4) in desired rates.
