A system for recuperation ram-jet ventilation for living spaces

摘要

The system for recuperation ram-jet ventilation consists of a heat exchanger with a set of thin-walled tubes (1) arranged in the ventilation duct (2), where the supply air is fed into the overpressure ventilated area (7) by these thin-walled tubes (1). The ventilated air is conducted away from the vacuum space (8) by the remaining space of the ventilation duct (2) outside the thin-walled tubes (1). For this type of ventilation, it is convenient to use the space between the chimney body (9) and the chimney insert (11) as the ventilation duct (2), thus using the recuperation ventilation system also as an additional hot-air exchanger reducing the heat loss by venting the flue gases through the chimney.
