Abstract

PROBLEM TO BE SOLVED: To provide a ventilation system capable of ventilating the inside of a dwelling house to prevent hot air in summer season and eliminate a heat loss in winter season in the dwelling house with a roof-space. SOLUTION: In this dwelling house with the roof-space 1, an air feed means 2 is installed in a habitable room, an exhaust means 3 is installed in a nonhabitable room, and these means are connected to each other in the roof- space 1. A changing mechanism 4 capable of changing the direction of air flow 5 is installed at a connection part. In summer, the air inside the dwelling house is exhausted through the roof-space 1 and, in winter, the air is fed to the dwelling house through the roof-space 1. Thus, the insides of the dwelling house and the roof-space 1 can be ventilated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system capable of simultaneously ventilating the inside of a house and the space behind a hut to enhance the durability of the house.

[0002]

2. Description of the Related Art In a space behind a hut in a house, heat insulation is applied to a ceiling on the top floor, and its thermal environment has been neglected.

[0003] Therefore, in summer, there is a problem that the heat flowing through the cabin through the ceiling cannot be sufficiently prevented from flowing into the room through the ceiling, resulting in an increase in room temperature and an increase in cooling load.

[0004] In addition, when ventilation is performed in winter, there is a problem that a cold draft and an increase in heating load are caused because outside air is directly introduced into a room.

[0005] Since the ventilation in the space behind the hut is also left to natural drive, the problem of dew condensation and the decay of the wood accompanying the condensation is latent.

[0006]

The problem to be solved is to improve the environment by controlling the inflow and outflow of heat and moisture in the space behind the hut, and also to improve the indoor thermal environment and ventilation. It is.

[0007]

According to the present invention, contaminated air in a room is exhausted into a vaulted space in a summer through a hut space on a ventilation path, and in a winter, fresh air is introduced into a room from a hut space in a winter. By introducing air, the inside of the cabin and the inside of the house are ventilated by the same route, thereby solving the above problem.

[0008]

FIG. 1 is a sectional view of an embodiment of the apparatus of the present invention.

An air supply means 2 is installed in a living room of a house, and an exhaust means 3 is installed in a non-living room.

These means are connected by a conversion mechanism 4 in the cabin back space 1.

The conversion mechanism 4 is connected to the cabin back space 1 and the outside air by another system.

The conversion mechanism 4 has a structure capable of changing the direction of the air flow 5 depending on the conditions of use.

[0013]

According to the present invention, general ventilation of the house and reliable ventilation of the attic space 1 can be achieved.

Further, the heating and cooling load of the house can be reduced.

Claims (3)

[Claims] In the summer, the air staying in a room is exhausted into a back space of a cabin to reduce the temperature of air in the back space of a cabin,
Ventilation system that promotes ventilation in the space behind the hut 2. A ventilation system for introducing warm air in a cabin space into a room in the winter to supply air warmer than direct introduction of outside air and to promote ventilation in the cabin space. 3. A ventilation system capable of performing the ventilation means according to claim 1 and 2 on the same route only by changing the flow of air.
