SILF ventilator is a compact air handling unit with heat recovery designed for creation of a continuous air exchange inside of small and middle-size domestic and public premises. Use of built-in heat exchanger allows using the heat from the air exhausted from the room for heating the inflowing clean air. Thanks to thermal energy saving, SILF ventilator may be an element of energy-saving technologies used in modern premises.
Operation
Warm air from the room is directed through a cleaning filter to the heat exchanger and, after a portion of heat is transferred to the exchanger, the air is exhausted by a centrifugal exhaust fan. Cold outer air is also directed through the cleaning filter to the heat exchanger where it absorbs a portion of heat from the exhaust air, and after that it is blown inside the room by a centrifugal inflow fan. The built-in heat exchanger allows transferring largest portion of heat from the exhaust air to the inflow air, which makes it possible to significantly cut down the costs of heating the premises and to reduce losses of heat energy in the cold period of the year. The ventilator is mounted on inner walls of the premises and is connected to air ducts of 80 mm diameter. Air exhaust and inflow may be effected both directly and through a system of air ducts.
