Air handling units are designed to assure the efficient exchange of air in public utility rooms and in living apartments. The aim of the air handling unit is to deliver fresh air from the outside and outflow the used air from rooms with the simultaneous heat recovery. The basic aim of air handling units with recuperation is first of all: the mechanic constraint of the air circulation during the process of ventilation of rooms. The second thing is the heat recovery from the exhausted air. The third aim is to filter the air flown into rooms.
Air handling units for exhaust and intake ventilation enable a constant exchange of air, assuring healthy and comfortable conditions of living in buildings and rooms, and breathing fresh air. Heat recovery from the removed air decreases the costs of heating a given building.
