JPS589709Y2 - Indoor ventilation system using a sunroom - Google Patents

Description

[Detailed description of the invention] This invention relates to an indoor ventilation system using a sunroom.

When the outside air is cold, such as in winter, people tend to close the windows, so it is necessary to ventilate the room from time to time.

However, if outside air is directly taken in during ventilation, the heated indoor air escapes and the room becomes cold, which is completely uneconomical.

This invention was made in view of this point, and the object is to provide a ventilation system that can obtain hot air extremely advantageously in terms of heat costs and supply it into the house.

This invention will be described below with reference to embodiments shown in the drawings.

In this specification, "front" means the left side of FIG.
, the rear refers to the right side of the figure.

In Figures 1 and 2, 1 is the main body of the house, 2 is its vertical outer wall, and 3 is a sunroom connected to the main body of the house 1 in contact with the outer wall, with a transparent glass plate fitted in the front. door 4
are arranged.

5 is the sloping roof of the sunroom, which is also mainly composed of glass plates.

Reference numeral 6 denotes both side walls of the sunroom 3, which are made of a plurality of heat insulation panels consisting of an aluminum plate and a heat insulation layer placed inside the aluminum plate.

7 is an intake fan attached to the upper front corner of one side wall 6; 8 is a blower fan attached between the sunroom 3 and the main body of the house 1; 9 is a fan attached to the vertical outer wall 2 at a position above the sunroom 3; It is an exhaust fan.

Note that 10 is a sunshade provided on the vertical outer wall 2, which was used as a window sunshade before the sunroom was installed.

In the above configuration, when the outside air is cold such as in winter, fresh outside air is first taken into the sunroom 3 and heated by solar heat when ventilating the room.

Then, the heated air thus generated is sent into the room of the house by the blower fan 8, and at the same time, the dirty air inside the room is exhausted by the exhaust fan 9.

In this case, the intake fan 7 is also operated at the same time to supply fresh outside air into the sunroom 3.

Based on the above, the ventilation system according to this invention can be applied to the main body of the house.
An intake fan 7 is installed in the sunroom 3 connected to the sunroom 3, a blower fan 8 is installed between the sunroom 3 and the house main body 1 to send warm air into the house, and an exhaust fan 9 is installed in the house main body 1. Since it is attached to the solar panel, when the outside air is cold, it can be heated in advance by solar heat in the sunroom, and then this warm air can be sent into the house to ventilate the room.

Therefore, since cold air does not directly enter the room, it is extremely advantageous that the cost for heating the room can be greatly reduced.
