A method for determining the positions of a number of fans (V.sub.n,m) for generating an air flow in a preferably enclosed space. The fans (V.sub.n,m) have an acceleration sensor to determine their position. The fans (V.sub.n,m) are arranged in rows (R.sub.1, R.sub.2, . . . , R.sub.n) and columns (S.sub.1, S.sub.2, . . . , S.sub.m). At least the position (i, j) of one fan (V.sub.i,j) is known.
