A VENTILATING ARRANGEMENT AND A HEAT EXCHANGING ASSEMBLY

摘要

A ventilating arrangement for ventilating spaces (4) in a building has at least one heat exchanging assembly for heat exchange between exhaust air from the building and outdoor air supplied to the building. An outdoor air channel (14) conducts through an opening (12) in the external wall of the building outdoor air to the heat exchanging assembly. Exhaust air is conducted through exhaust air members (7) to the heat exchanging assembly. The flow of air to the spaces from the exterior of the building through supply air members (11) connected to the heat exchanging assembly only takes place through the negative air pressure generated in the spaces of the building through a flow of exhaust air leaving the spaces through said exhaust air members.
