FIELD: ventilation and air conditioning.
SUBSTANCE: invention is intended for use in supply and exhaust ventilation systems of residential and industrial buildings. Diaphragm heat exchanger comprises a heat exchange membrane made of a thin-wall zigzag-shaped sheet to form ribs perpendicular to the long side of the sheet. Heat exchange membrane is installed in fixing cartridge so that membrane ends are sealed, and in opposite sides of holder there are slots for air passage.
EFFECT: higher efficiency of heat transfer.
