Referring to FIG. 13, when the power distributor gear 12 rotates by wind, the intake gear 13 and the exhaust gear 14 installed to be engaged at equal intervals on the outer circumferential edge are rotated, and at this time, The drive gear 16 installed in engagement with the power distributor gear 12 is idle.

14A and 14B, bolts 77a and 77b formed at one side of the main supply pipe 1 and the main exhaust pipe 2 are fastened to the nut parts 76a and 76b formed at both sides of the pressure release means 70. The hemispherical sealing member 72 is raised and lowered by the spring 71 in the receiving groove 75 in which the first exhaust hole 73 and the second exhaust hole 74 are formed on the pressure release means 70. It is configured to be.

That is, when the wind blown and exhausted to the main supply pipe (1) and the main exhaust pipe (2) is greater than the elasticity of the spring (71), the sealing member (72) rises to the receiving groove (75), the spring when the wind is lowered By the elasticity of the 71, the sealing member 72 is lowered.

Therefore, when the sealing member 72 is raised, the first exhaust hole 73 is opened, and the air introduced into the first exhaust hole 73 is discharged to the outside through the second exhaust hole 74.

In addition, the soundproof tube 61 is provided on the inner surface of the soundproof member 63 for absorbing sound waves, and is configured to block noise from entering the building room Br.

Referring to FIG. 16, the outside air blown through the main supply pipe 1 has a high temperature difference in summer and a low temperature difference in winter.

Therefore, in order to prevent the temperature loss by the outside air blown into the room (Br) that has been cooled and heated, the heat exchange member (32a) has a cooling and heated temperature of the polluted air discharged out of the room (Br). The external air passing through the heat exchange member 31a by mutual heat transfer to the heat exchange member 31a has a cooling / heating temperature similar to that of the air inside the building, thereby preventing a temperature loss. .

Referring to FIGS. 17A and 17B, the condensate w is drained to the condensate hole 41 to discharge the condensate w generated by the temperature difference in the room, and the condensate w is drained. It is formed so as to gather in the red chamber 42.
