CASING Casing construction basing on the the framework made of aluminum profile. Layer panels filed with 25 mm thick mineral wool. Galvanized panel sheet. Varnished on outer side. SPOUTS Connecting spouts with huge diameter ensuring the small exhaust air velocity between 3-5 m/s. Equipped with gasket, adapted to direct assembling of spiro pipes LEAKTIGHTNESS Special gaskets eliminating air leak between the supply and exhaust. FEET Special feets are designed for placing purposes equipped with adjusting screws, enabling leveling of the entire device. DRIP TRAY Device is equipped with drip tray made of stainless sheel in order to remove the condensates produced as a result of water steam condensation in heat recovery exchanger. BY-PASS By-pass of the exchanger for heat recovery ensuring stable operation of the device. It is used as a protection of the exchanger against frosting and ensures the operation in the summer time. FILTERS Class G4 cassette filters. Huge filtering surface ensuring long filter life. Small starting flow resistance which doesn't exceed 10Pa. Easy assembling when changing the filter AUTOMATICS Various automatics options permit for comfort operation of the device in various working modes for example: day time, night time, summertime, wintertime. Well visible user's interface ensures easy and simple operation of the device. FANS High duty fans with direct drive. Commutated single/phase motors with external rotor supplied by voltage 230V. Low power consumption, between 52 and 420 W HEAT RECOVERY In order to recover the heat is used the series of crossing-flow counter current exchanger types with the total efficiency above 80%. Exchangers are made of plates

PRESSURE DROP CHARACTERISTICS OF HEAT EXCHANGERS

CALCULATION OF DISPOSABLE COMPRESSION Disposable compression is calculated on the basis of attached fan characteristics, resistances of c o u n t e r - c u r r e n t heat exchangers and filters resistances. Regarding the very small clean filters resistance (max.10 Pa) for calculations is accepted the value of filter contamination according to the standard PN-EN 1886 which is 75 Pa. Disposable compression is calculated on the basis of following formula: Pdys = 0,95 x (Pstw - Rwp - 75) [Pa] where: - Pdys – disposable compression of the device [Pa] - Pstw – fan static pressure [Pa] - Rwp –...

RGS RECUPERATORS SUPPLY AIR TEMPERATURE CALCULATION Supply air temperature is calculated according to the following formula: T2 = T1 + η x (T3-T1) where: T1 - fresh air temperature [°C] T2 - supply air temperature [°C] T3 - exhaust air temperature [°C] η - temperature efficiency of exchanger [%] EXAMPLE: - air flow 400m3/h - fresh air temperature T1 = -10°C - exhaust air temperature T3 = +20°C - chosen device size RGS-500 Basing on the graph showed on the previous page we can see that temperature efficiency is 82,5%. After using this formula we receive: T2 = -10 + 0,825 x (20 - (-10)) T2 =...
