Abstract
The invention relates to a method and arrangement for adjusting an air-conditioning system by means of relative adjustment, in which the supply/exhaust air valves (1 - 5) of the system are adjusted starting from a valve (1) located the remotest in a branch duct (6), a so-called reference valve, so that the air flow rate of the reference valve is measured and the ratio of the air flow rate of the reference valve and the designed air flow rate is calculated and the other valves (2 - 5) of the branch duct (6) are adjusted in order starting from the reference valve so that each valve has the same ratio of the measured and calculated air flow rate and the designed air flow rate as the reference valve. For simplifying the measurement, after the measurement of the reference valve, the measuring duct of the following valve is connected parallel with the measurement of the reference valve, the ratios of the measured air flows and the designed air flows are generated, the ratio of the following valve is compared with that of the reference valve, and the adjustment of said following valve is carried out by comparing the above-mentioned values that may be observed parallel.
