at a Ventilation Symposium at the ASHRAE Semiannual meeting in Chicago 1961 The description of the method as reported in the technical press is not very clear but it appears to be a method in which attempts are made repeatedly to set absolute values ac main branches before a proportional balance has been achieved in the whole system
A fan 1 is used to send the foul air extracted from a confined building or structure into one or more towers in series The air is injected into the tower beneath the floor 2 supporting the packing 3 through which the reagent percolates The gaseous compounds are absorbed and the chemical reactions described earlier take place within this packing As the air leaves the …
