Abstract

PROBLEM TO BE SOLVED: To suppress a decrease in a surface temperature of a pipe and to suppress a dew formation by splitting an interior of the pipe by a partition wall formed of a material different from that of the pipe but and having high thermal conductivity into a supply route and an exhaust route. SOLUTION: The one pipe 1 has a structure split in an interior into a supply route 3b and an exhaust route 3a by a partition wall 2. The supply and exhaust pipe P is formed of a material different from that of the pipe 1, for example, a material having high thermal conductivity such as copper, aluminum or the like. The pipe 1 may be formed of a vinyl chloride resin or the like. Thus, the wall 1 is formed of the material having the high thermal conductivity such as the copper, the aluminum or the like. In this manner, in the case of simultaneously feeding supply gas b and exhaust gas a through the route 3b and the route 3a, the gas b can heat exchange with the gas a.

As described above, the supply / exhaust pipe (P 0 ) shown in FIG. 4 is effective for constructing a one-pipe heat exchange ventilation system which is reasonable and requires less construction. However, it is also true that there are the following problems.
That is, the supply and exhaust pipes (P
In ( 0 ), both the pipe (41) and the partition (42) are made of the same material, generally a vinyl chloride resin. The hollow layer (32) provided on the room (A) side of the wall (32)
If the airtightness between a) and the room (A) is not sufficient, if the outdoor (B) is at a low temperature and the room (A) is at a high humidity, the room (A) enters the hollow layer (32a). Due to the humidity, dew condensation (d) is likely to occur on the surface of the pipe (41) on the air supply path (43b) side through which the low-temperature air (b) flows in the air supply / exhaust pipe (P 0 ). This is because the surface of the pipe (41) on the side of the air supply path (43b) is cooled by the low-temperature air supply (b) flowing through the air supply path (43b), and the surface temperature of the room (A) is reduced. This is because the temperature is lower than the temperature. The condensation (d) generated in the wall body (32) in this way causes corrosion of the wall body (32) and must be avoided by all means.

Therefore, it is conceivable to attach a heat insulating material to the outer periphery of the pipe (41) located in the hollow layer (32a) in the supply / exhaust pipe (P 0 ). Not only that, but also the work of construction, worsens the workability. Also, by installing the heat insulating material,
Although condensation (d) on the surface of the pipe (41) located in the hollow layer (32a) is suppressed, the pipe (41) is provided between the pipe (41) and the heat insulating material (32b) provided on the wall (32).
