METHOD FOR CONTROLLING THE SUPPLY AND THE DISCHARGE OF HOT AIR TO AND FROM, RESPECTIVELY, A BLOWING TUNNEL

摘要

we have developed a process for controlling supply and discharge of hot gases and / or cold respectively into and from an arrangement (1) in the form of a tunnel, in order to dry and / or cool vehicles or parts of vehicles.the combination in the form of a tunnel is divided lengthwise into a number of sections, each of which has a plurality of nozzles (7, 20, 21, 22, 23, 24, 25), preferably 60 to 250.which is almost equally distributed on the inner surface of the bent section and through which gases are blown against the vehicle, and or parts thereof passing through the arrangement. the pressure drop of the gas in the nozzle, and the gas temperature in the nozzle.we then compared the values of pressure drop with appropriate values corresponding to the prevailing temperature, it transmits a signal to increase or decrease in pressure at a first pressure change (29) in order to supply arrangement (1) for gas, according to the measured values are less than or greater than the desired values.
