6.6.1 - MEASURINGOFTHEAIRVOLUME

Follow these instructions: 1.- Measure the net surface in mt2 of the inlet grill without the frame. 2.- Measure the air speed on different points of the grill. 3.- Add up the different speed values and divide them by the number of measurements to obtain the air speedaverage (in mt/s or mt/m according to the measuring instrument).4.- Thanks to one of the following formulas it is possible to draw the air volume in the system:V = SxSx3600V = SxSx60 Where:V = mt3/h of conditioned air S = surface in mt2 of the grill without the frame S = air speed in mt/s or mt/m 3600 = for the speed in mt/s. 60 = for the speed in mt/mFrom these formulas it is possible to draw the following ones: Compare the volume in mt/3/h with the value indicated in the table of technical specifications. If the air volumeis lower of 15/20% than values in the table (but not more than 15/20%), the value can be considered normal. The measurement on the outlet grill can be useful for the balancing if there are more outlet grills for a com- paraison with the air volume of the outlet grill. To air-condition two or more cabins, it is necessary to calculate the air volume to introduce. To obtain this value, divide the air volume obtained from the previous measure- ment by all air-conditioned mt3 (ratio between conditioned air and conditioned volume). Multiply this value by volumes of each cabin to obtain a rough value of the conditioned air to introduce.Example: pag. 29
