VENTILATION DEVICE FOR FARM BUILDING, ESPECIALLY FOR ANIMAL HUSBANDRY, COMPRISING A HEAT EXCHANGER AND MEANS FOR HEATING THE AIR

摘要

The invention relates to a ventilation device (10) intended to equip a livestock building (90, 91), comprising a housing (1) and at least one heat exchanger block (4), the housing (1) being provided with an outside air intake (2), a heated air outlet (2a), an indoor air intake (3) and a cooled air outlet (3a), said at least one heat exchanger block (4) being able to thermally contact a first flow (A) of air coming from the outside air intake (2) with a second flow (B) of air coming from said indoor air intake (3). According to the invention, the ventilation device (10) further comprises an auxiliary air outlet (5) disposed on said casing (1), air heating means (8) and deflection means adapted to directing said second incoming airflow (B) to the location of said inner air intake (3): - through said at least said heat exchanger block (4) to said cooled air outlet (3a) according to a first air circuit (C1), - through the heating means (8) to said heated air outlet (2a) according to a second air circuit (C2), or - directly to said auxiliary air outlet (5) according to a third air circuit (C3).
