HEAT EXCHANGE MEDIA AND ENERGY RECOVERY VENTILATOR USING THE SAME

摘要

PURPOSE: A heat exchange media and an energy recovery ventilation device using the same are provided to maximize contact frequency between air and a metal surface and increase time that the air is stayed in the heat exchange media, thereby improving heat exchange efficiency. CONSTITUTION: A heat exchange media(1) has a coiled structure in multi stage. The metal foil is stretched in vertical direction of the blade scars to form tridimensional diamond shaped air gaps in a state where a metal foil has blade scars in predetermined intervals. The air flowed in from the outside passes through the air gaps and gets in contact with a metal surface so that heat exchange is implemented. The angle between the air gaps and the air flow is within 40 to 50 degree.
