The present invention relates to a counterflow ventilator using a heat transfer element. The counterflow ventilator using a heat transfer element comprises multiple element cores each comprising of a spacer which is formed in a waveform to maintain stiffness and a shape, and forms a heat exchange passage to enable indoor air and outdoor air to pass through the inside, and a membrane attached to a lower surface of the spacer, and in which heat and moisture are transferred for a transfer heat exchange; a main body of the ventilator in which an introduction unit and a discharge unit for introducing and discharging the indoor air, and an air supply unit and an air exhaust unit for supplying and exhausting the outdoor air are formed while facing each other, the element cores are installed at the introduction unit, the discharge unit, the air supply unit, and the air exhaust unit by being alternately stacked in a crisscross pattern, and a discharge header which communicates with the discharge unit to discharge the indoor air to the outside, and an exhaust header which communicates with the air exhaust unit to exhaust the outdoor air to the inside are included; and a cross flow heat exchange unit which is configured at the discharge header and the exhaust header to secondarily exchange heat with the discharged or exhausted air. |
