Description

[0001]
[Industrial application fields]
This invention relates to a ventilation equipment of the building, in particular about the room ventilation equipment of the heat-exchange.
[0002]
[Prior art]
Highly insulated houses are aimed at living in a comfortable room temperature in summer and winter, and in many cases, the windows remain closed. In particular, in cold regions, the room is often sealed in order to perform heating economically. However, if the windows are not opened, the air becomes dirty and the humidity increases. Further, with the development of sash technology, the airtight performance of the window itself has been improved, so that measures for indoor ventilation and prevention of condensation are necessary. Thus, planned ventilation has become an important issue in highly insulated and airtight houses. For this reason, various techniques using a ventilation fan have been proposed.
[0003]
As the conventional planned ventilation, there are two types of built-in type ventilation that uses a wall-mounted type ventilation unit and a built-in exchanger on the ceiling and turns the duct around the required room using a heat exchange type ventilation device with low heat loss. Technology is known.
[0004]
For example, as a heat exchange type exhaust fan, a separate type heat exchange type exhaust fan embedded in the ceiling of a living room or dining room is known. This separate heat exchange type ventilation fan embedded in the ceiling does not open the window, so it can be comfortably ventilated without impairing the cooling and heating effect, and the heating and cooling effect by high insulation can be maintained because the window can not be opened. It is possible, such as inhaling dirty air in the dining room, exhausting it outside, taking in fresh outdoor air, supplying it to the living room, etc., without damaging the comfortable room temperature by heating and cooling, without opening the window It has an excellent feature that it can be performed.
[0005]
In addition, as a simpler technique than the heat exchange type ventilation fan, a ventilation fan is attached to one corner of the wall, or a ventilation fan or ventilation unit is fitted in a part of the window sash, and the outside air is taken in by operating these occasionally. Technology is also known.
[0006]
[Problems to be solved by the invention]
The above heat exchange type ventilation fan not only needs to be installed on the ceiling, but also requires a large facility, and equipment such as piping and heat exchangers must be arranged in the space behind the ceiling. In particular, there has been a problem that it cannot be arranged unless it is determined in advance in the overall plan at the time of design.
[0007]
In addition, the technique using a ventilation fan is a simple method that can be retrofitted, but it requires a wall facing the outer wall, which is an obstacle to the installation of furniture and has a problem that the mounting appearance is unsightly. In other words, because the installation position of the ventilation fan is one corner of the wall or the opening of the window, not only is it difficult to secure the installation position, but the indoor design is limited, which interferes with the arrangement of furniture, etc. There was a design inconvenience.
[0008]
In addition, a technique is known in which a movable panel is used above and below the window sash to ventilate the panel by opening and closing the panel (for example, Japanese Patent Application Laid-Open No. 8-277855) and a ventilation unit is provided in the window sash. In these techniques, when the ventilation unit is attached to the window sash, there is a disadvantage that the daylighting area is reduced and the appearance of the window is deteriorated.
[0009]
An object of the present invention is to provide a heat exchange type indoor ventilator that can ventilate the room temperature without breaking the room temperature condition and does not give an uncomfortable feeling to the indoor design.
[0010]
Another object of the present invention is to provide a heat exchange type indoor ventilation device and a mounting method which can be unitized and can cope with a large-scale refurbishment or change in floor plan.
[0011]
[Means for Solving the Problems]
The above problem is solved in a heat exchange room ventilation system according to claim 1 is arranged on the indoor side, and an upper space of the curtain box which is partitioned in partition member, the upper portion of the opening portion of the partition member and the continuous wall An electric shutter box covered with an outdoor hood connected to the connecting member, and a window arrangement upper space that is formed by a connecting member formed on the side and an upper portion of the window frame and continuous with the upper space of the curtain box; An electric shutter box and an outdoor hood arrangement space arranged continuously outside the window arrangement upper space and an outdoor hood arrangement space, and a heat exchanger and an air supply / exhaust fan are arranged in any of the above spaces Is solved.
In this specification, “space” in the curtain box arrangement space, the window arrangement space, the electric shutter box, and the outdoor hood arrangement space is also used as a word indicating an arrangementable position.
[0012]
If it is configured as in the above-mentioned claim 1, since the upper side room space of the window which is an opening set in the outer wall surface is necessarily used if it is a living room, it does not compete with the arrangement position of furniture etc. Can solve aesthetic problems.
Further, since the shutter is disposed at the hood position of the outdoor air supply / exhaust duct because it is provided at the upper portion of the window, the shutter disposed portion can be used also as the hood disposed position, and the appearance is not impaired.
[0013]
Moreover, since the window itself is not touched at all, it is possible to unitize all of lighting, shielding, crime prevention, and ventilation (planned ventilation) by the opening of the window. For this reason, when a design change or a remodeling / change due to a change with the passage of time, the replacement is easy, and the degree of freedom of design increases in the building design.
[0014]
In addition, since each window frame can be unitized, it can be manufactured at the factory, and the unit including the window frame manufactured at the factory can be removed at the site, reducing the number of on-site man-hours. It is possible to secure and guarantee.
Furthermore, since the upper space of the curtain box is used in this way, there is no sense of incongruity when viewed from the indoor side, and the arrangement of furniture and the like is not disturbed.
[0015]
At this time, the air supply / exhaust fan rotates when the window sash and the sensor disposed on the window frame detect that the window sash is closed, and when the window sash is detected to be opened. The rotation is controlled to stop.
With this configuration, when a window that requires indoor ventilation is closed, ventilation by the fan is performed, and when the window is open, the fan is stopped and ventilation is performed from the window. it can. Since it is configured in this way, it is possible to always stably ventilate the room when the window is closed, and to save energy because the fan can be stopped when the window is open and ventilation is not necessary. To contribute.
[0016]
Furthermore, an alarm device is provided that is activated when it is determined that the air supply / exhaust fan is not rotating when the window sash is closed.
By comprising in this way, by providing an alarm in the position which can be notified to a resident, the operating state of a heat exchange type indoor ventilation device can be notified, and it can constitute so that it may operate for 24 hours .
[0017]
At this time, the heat exchanger and the air supply / exhaust fan can be formed separately and arranged in any one of the spaces. In this way, if the heat exchanger and the air supply / exhaust fan are separated, each arrangement space can be freely selected, so that the heat exchange type indoor ventilation device can be designed and made compact and the design flexibility can be increased. It can be secured.
[0018]
Also, contrary to the above, the heat exchanger and the air supply / exhaust fan can be integrated into a unit and arranged in the upper space of the curtain box arrangement on the indoor side. The space on the inconspicuous curtain box can be used effectively, and the heat exchange type indoor ventilation device can be miniaturized, and effective heat exchange is possible even with a narrow window width (between walls).
[0019]
Further, a duct is formed between the electric shutter box and the outdoor hood, and the duct is connected to the heat exchanger and the air supply / exhaust fan side. A duct is formed, and the temperature influence on the electric shutter can be reduced, and the appearance is excellent.
[0020]
In addition, the heat exchange type indoor ventilation device described above is preferably formed integrally with the window frame. That is, by being unitized with the window frame, it can be attached as it is to the opening in which the window of the building is formed. For this reason, since the window frame and the heat exchange type indoor ventilation device are integrated, the window itself is not touched at all, so all the lighting, shielding, crime prevention, and ventilation (planned ventilation) are performed by the opening of the window. It becomes possible to unitize. In addition, because each window frame can be unitized, it can be manufactured at the factory, and the unit including the window frame manufactured at the factory is removed on site to reduce the number of on-site man-hours, ensuring the finish and quality.・ A guarantee can be made.
