FIELD: the invention refers to systems of ventilation assigned for exchange of the air in the room and outside air.
SUBSTANCE: the system has a fine-wire heat exchanger having the first and the second channels, which are in the contact with warmth exchange with each other. The first channel has an inlet opening connected with the outside air and an outlet opening connected with the air of the room. The second channel has an inlet opening connected with the air of the room and an inlet opening connected with the outside air, the means of balancing assigned for balancing of the flows in the both channels that provides maximal transfer of warmth. Besides, the invention refers to combination of the front, room adjoining to the front and the systems of ventilation in which the inlet opening of the first channel of the system is connected with the outside air outside of the front and the outlet opening is connected with the air of the room, and the inlet opening of the second channel is connected with the air of the room and the outlet opening is connected with the outside air.
EFFECT: restoration of warmth with sufficient effectiveness.
