2 KLIMA Co. Flow and system stress should be known factors in air flow. The flow is gas quantity flowing through the system during given time unit and is measured as m /sec or m /h. System stress is the amount of energy that each kg of gas must have in order to be able to flow through the system in particular quantity per given time unit and is expressed as J/kg or J/m. System characteristics are the relation between the flow and system stress. Some ratios of important ventilator parameters arising from the law of simmilar flow A- At the change of number of revolutions: - Volume of flow has a linear relation in regard to the change of ventilator"s number of revolutions V1 n1 V2 n2 - Pressure (static, dynamic and total) is in proportion to the square of change in number of revolutions D1 (n1) 2 2 D2 (n2) - Required driving power supplied to ventilator shaft is proportional to the cube of change in number of revolutions P1 (n1) P2 (n2) B- At the change of air temperature: - Pressure alters in linear proportion of air temperature - Required driving power supplied to ventilator shaft is in proportion to square of change to air temperature P1 (T1) 2 P2 (T2) 2 Za strujanje vazduha u kanalima treba poznavati protok i napor sistema. Protok je koli~ina gasa koja proti~e u jedinici vremena kroz sistem i meri se u m /s ili m /h. Napor sistema predstavlja koli~inu energije kojom svaki kilogram gasa mora da raspola`e da bi proticao u odre enoj koli~ini u jedinici vremena kroz sistem i meri se u J/kg ili J/m. Veza izme u protoka i napora sistema data je karakteristikom sistema. Neki odnosi me u va`nim parametrima ventilatora koji proisti~u iz zakona sli~nog strujanja A - pri promeni broja obrtaja: - zapreminski protok se menja sa promenom broja obrtaja ventilatora linearno V1 n 1 V2 n 2 - Napor (stati~ki, dinami~ki i ukupni) menja se proporcionalno kvadratu promene broja obrtaja. Dp1 (n1) 2 2 Dp2 (n2) - Potrebna pogonska snaga dovedena vratilu ventilatora menja se proporcionalno tre}em stepenu promene broja obrtaja P1 (n1) P2 (n2) B - pri promeni temperature vazduha: - Napor se menja proporcionalno promeni temperature vazduha - Potrebna pogonska snaga dovedena vratilu ventilatora menja se proporcionalno kvadratu promene temperature vazduha P 1 ( T 1 ) 2 P 2 (T2) 2 Dlæ te~eniæ vozduha v kanalah neobhodimo znatý rashod i napor sistemÿ. Rashod eto koli~estvo gaza prohodæåego v edinicu vremeni ~erez sistemu i izmeræetsæ v m /sek ili m /~as. Napor sistemÿ predstavlæet koli~estvo çnergii, kotoroî obladaet ka`dÿî kilogramm gaza dæa togo ~tobÿ protekatý v opredelennuõ edinicu vremeni ~erez sistemu i izmeræetsæ v J/kg ili J/m. Vzaimosvæzý me`du rashodom i naporom sistemÿ dana v harakteristike sistemÿ. Nekotorÿe sootno{eniæ me`du va`nÿmi parametrami ventilætora kotorÿe proishodæat iz zakona podobnogo te~enie A - pri izmenenii ~isla oborotov: - Emkostnÿî rashod izmenæetsæ s izmeneniem ~isla oborotov ventilæatora linearno. V1 n1 V2 n2 - Napor (stati~eskiî, dinami~eskiî i obåiî) menæetsæ proporcionalýno kvadratu izmeneniæ ~isla oborotov. Dp1 (n1) 2 Dp2 (n2) 2 - Neophodimaæ privodnaæ mo{nost podvedennæ na val ventilætora menæetsæ proporcionalýno tretýeî stepeni izmeneniæ ~isla oborotov. P1 (n1) P2 (n2) B- pri izmenenii temperaturÿ vozduha: - napor izmenæetsæ s izmeneniem temperaturÿ vazduha linearno - Neophodimaæ privodnaæ moånostý podvedennaæ na val ventilæatora izmenæetsæ proporcionalýno kvadratu izmeneniæ temperaturÿ vozduha P1 (T1) 2 P 2 (T 2 ) 2
