Heat Exchange Ventilator

Energy-Saving Heat Exchange Ventilator

This technology relates to a heat exchange ventilator, and more specifically, to an energy-saving heat exchange ventilator that minimizes thickness by embedding a total heat exchanger and using only one blower fan and one total heat exchanger, thereby replacing existing ventilators installed within windows and ducts.

Existing ventilation systems forcibly exhaust indoor air to the outside without any means for heat exchange. This leads to significant energy waste, as warm indoor air heated in winter is discharged outdoors, and cooled indoor air in summer is forcibly expelled. To address this, we propose a method that blocks the rear of the blower fan and the front of the total heat exchanger, thereby generating airflow through the rotation of the blower fan.

This technology minimizes the ventilator's thickness by positioning the total heat exchanger either below or above the blower fan. By configuring the outdoor and indoor airflows, generated by the blower fan's rotation, to pass through the total heat exchanger, it ensures smooth heat exchange between the outdoor and indoor air with a simple structure, thereby enabling significant energy savings.

Key Features:

• The front casing features an indoor air outlet at the top and an outdoor air inlet at the bottom.
• The rear casing features an air outlet at the top and an indoor air inlet at the bottom.
• The total heat exchanger is positioned either below or above the blower fan, with the rear of the blower fan and the front of the total heat exchanger blocked.
• Outdoor air enters the indoor space after passing through the total heat exchanger, while indoor air is discharged outdoors after passing through the total heat exchanger.
