Decentralized ventilation system with heat recovery TM «CLIMTEC»
removes exhaust air from the room and at the same time fills it with
fresh air from the street.
Inside there is an aluminum heat exchanger (aluminum does not
oxidize, unlike copper and other materials that have high thermal
conductivity, it does not have a negative effect on human respiratory
system, it allows you to work in wide temperature range, has a natural
protection (oxide film) against corrosion, prevents development
of fungal and putrefactive bacteria on the lamellas of the heat
exchanger), which takes heat from the room and then gives it to the
air streams from the street, and heats them.
The air from the room passes through the recuperator through one
fan, and the air from the outside through another other. In this case,
the air flows are divided in such a way that when the fans are running,
they do not mix, but move in different channels of the heat exchanger
in opposite directions.
Determination of the coefficient of efficiency of recuperation is
carried out by calculation using the formula:
where:
Kt — heat recovery efficiency factor;
T1 — outdoor temperature, °С;
T2 — extract air temperature (room air), °С;
T3 — supply air temperature, °С
Kt = (T3-T1 / T2-T1) x 100%
