Nisam siguran da moze da zadrzi 95% toplote, jer radi na principu da spoljasnji vazduh koji se ubacuje izmeni toplotu sa unutrasnjim vazduhom koji ide napolje, tako sto se cevi kuda ide vazduh dodiruju. Tako da je gubitak u najbolju ruku 50%.
PS: Sad sam pogledao karakteristike, naime zadrzava 40% energije koja bi se izgubila, a HEAT EXCHANGER ima efikasnost od 90-95%. Sad samo da izracunas koliko energije gubis na ventilaciju, pa vidi da li usteda u vidu zadrzavanja 40% te energije vredi dodatna ulaganja.

Brink boasts extensive experience in the field of recovery. For 14 years he has been producing RENOVENT recuperators. The main purpose of air handling units with heat recovery is a mechanical circulating the air in the ventilation of different types of rooms, and heat recovery from exhaust air and use it to heat the incoming air. Supply air and discharged from the room is filtered. Renovent HR is a modern device of this type on the market. It is characterized by simplicity and even construction and provides unique dot ± d line performance and reliability while maintaining unprecedented aesthetics. Thanks to the fan current in device technology CONSTANT FLOW provides over 40% power savings compared to conventional fans. With the sophisticated technology of fan power is modulated by the unit so that f provides a constant flow of air at a preset level regardless of the filter installation or weather conditions. This solution allows you to maintain proper ventilation even where competing devices do not have ± chance. The recuperator is used cross-counterflow heat exchanger efficiency averaged 90%, and in certain conditions of up to 95%. The materials used in the manufacture of heat exchangers provide not only excellent performance of the device as well as its reliability and 100% secondary processability. Everything to the environment.
Inace, u Poljskoj ovaj rekuperator je ~1.200 EUR.
