Description

[Detailed description of the invention] The present invention relates to an attic ventilation system that promotes ventilation of the attic in winter and prevents condensation.
The purpose is to provide a ventilation system for the attic that utilizes the exhaust heat of the heater and provides sufficient natural ventilation through the outer wall panels.

The present invention will be described in detail below based on illustrated embodiments.

In FIGS. 1 and 2, 1 is an exterior wall panel, and a wide outdoor ventilation hole 2 is provided at the lower part of the outdoor surface of this hollow exterior wall panel 1, and directly above the outdoor ventilation hole 2 at the upper end surface. A plurality of upper ventilation holes 3 are provided.

Reference numeral 4 denotes a heat dissipation pipe, which has heat dissipation fins 6 attached to its outer periphery and is disposed between the external ventilation hole 2 and the upper ventilation hole 3 in the outer wall panel 1.

In the figure, an exhaust pipe of a heating device 7 installed indoors is used as the heat radiation pipe 4, but a hot water supply pipe or the like may also be used.

However, the outer wall pipe 1 is installed so that the upper ventilation hole 3 communicates with the attic 5, as shown in FIGS. 3 and 4.
While the heating device 7 is in use, the air inside the outer wall panel 1 heated by heat exchange with the heat radiation pipe 4 rises, and the low-temperature, dry outside air taken in through the external ventilation hole 2 is also warmed and flows through the upper ventilation hole. Flows into the attic 5 through 3.

On the other hand, when heating is not performed from night to dawn, the air temperature inside the attic 5 and the exterior wall panel 1 becomes lower than the outside air temperature, and as shown in Figure 4, the air temperature in the attic 5 and the outside wall panel 1 becomes lower than the outside temperature, and as shown in Fig. 5
The air inside is exhausted through the outer wall panel 1.

In this way, in the winter season, when condensation tends to occur in the attic, from the heating time at night to the early morning, semi-forced natural ventilation is performed between the attic air and the outside air through the exterior wall panels, thereby preventing condensation. In addition to being effective, it is also economical if the exhaust pipe of a heating appliance is used as the heat dissipation pipe and exhaust heat is used.
