Simultaneously, along with starting working for gas fan (96), extraneous air is drawn into air exchange system inside by extraneous air suction inlet (52).The extraneous air that sucks is by air draught road, left side (54), and is drawn in the heat exchanger (60) through the lower left side face of over-heat-exchanger (60).At this moment, extraneous air is drawn into the inside of above-mentioned heat exchanger (60) more earlier by being installed on the prefilter (68) of heat exchanger (60) lower left side face behind the airborne foreign matter to be filtered.

Be drawn into the inner air of above-mentioned heat exchanger (60) and the room air of discharge and carry out the exchange of heat and moisture, and discharge by the upper right face of heat exchanger (60).Here, the upper right of heat exchanger (60) is provided with high-performance filter (73), is filtered by trickle foreign matter in heat exchanger (60) air again, makes air more pure and fresh.

Air by above-mentioned heat exchanger (60) and high-performance filter (73) is forced to send by giving gas fan (96), and the extraneous air of the right flank setting by casing (50) is sent mouthful (82) and is discharged to indoor.

Room air is discharged to the outside by scavenger fan (80).

Room air is drawn into air exchange system inside by indoor air sucting inlet (88), is imported and be drawn into through the lower right side of over-heat-exchanger (60) inside of heat exchanger (60) by air draught road, right side (92).

The lower right side of heat exchanger (60) is provided with prefilter (68), with airborne foreign matter in the filter chamber.Thus, heat exchanger (60) inside is drawn into fresh air, and protection heat exchanger (60) prolongs its life-span simultaneously.

Be drawn into the inner room air of heat exchanger (60) and carry out the exchange of heat and moisture, and discharge by the lower left side face of heat exchanger (60) with the outside outdoor air that sucks.Force to send by scavenger fan (80) from the room air that heat exchanger (60) is discharged, and the room air outlet (56) that the left surface rearward end by casing (50) is provided with is discharged to the outside.

Below with reference to Fig. 9 air flow condition under the general ventilatory pattern is described.General ventilatory pattern is applied under the little situation of the temperature of indoor and outdoors such as spring or autumn and psychrometric difference, and room air directly is discharged to the outside from bypass with obstructed over-heat-exchanger (60).

Therefore, when the user selected general ventilatory pattern, according to the instruction of control cabinet (100) internal control portion, windscreen (94) covered air draught road, right side (92).At this moment, will force to pass out to room air outlet (56) and discharge by scavenger fan (80) without heat exchanger (60) by indoor air sucting inlet (88) inhaled air.

Below observe the mobility status of extraneous air, when starting working for the gas fan, extraneous air is drawn into air exchange system inside by extraneous air suction inlet (52), the extraneous air that the sucks side draught air channel (54) that keeps left imports, and is drawn into the inside of heat exchanger (60) through the lower left side face of over-heat-exchanger (60).Extraneous air is drawn into the inside of heat exchanger (60) by being installed on the prefilter (68) of heat exchanger (60) lower left side face behind the foreign matter in the filtered air.

Be drawn into the inner air of heat exchanger (60), because the obstructed over-heat-exchanger of room air (60), will do not carry out the exchange of heat and moisture and directly discharge by the upper right face of heat exchanger (60).Here, the upper right of heat exchanger (60) is provided with high-performance filter (73), is filtered by the airborne trickle foreign matter of heat exchanger (60) again, makes air more pure and fresh.

Air by heat exchanger (60) and high-performance filter (73) is forced to send by giving gas fan (96), sends mouthful (82) by the extraneous air of casing (50) right flank setting and is discharged to indoor.

As mentioned above, general ventilatory pattern is different from the heat exchange ventilatory pattern, the inner exchange of not carrying out heat and moisture of its heat exchanger (60).
