The following performances of the ventilation system are determined by measurements and by the aid of a pressure-compensated air flow meter. (Figure 1 and 2)
Regarding the ventilation flow rate we measure the supply and / or discharge.The ventilation flow rate is established for the various modes of the ventilation system of all air supply-and exhaust valves. In addition, the flow rate of a possible receiving hood is measured at its highest level. This, however, is not added to the total air flow capacity of the ventilation system of the residence. The measurements are performed according to the method described in NEN 1087 (as prescribed in the BRL 8010).
The survey aims to answer the following questions:
