Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting a building ventilation system and a heat exchange type indoor ventilation system to a building, and more particularly to a heat exchange type room ventilation system and a heat exchange type room ventilation system. Related to the mounting method.

[0002]

2. Description of the Related Art Highly insulated homes aim to be a home that can maintain a comfortable room temperature both in summer and winter, and in many cases, windows remain closed. In particular, in cold regions, the room is often closed in order to perform heating economically. However, if the windows are not opened, the air becomes dirty and the humidity rises. Furthermore, with the development of sash technology, the airtightness of the windows themselves has been improved, so that it is necessary to take measures for room ventilation and dew condensation prevention. As described above, planned ventilation is an important issue in highly insulated and airtight houses. For this reason, various techniques using a ventilation fan have been proposed.

[0003] As the above-mentioned conventional planned ventilation, a heat exchange type ventilation device with small heat loss is used, and a living room unit ventilation with a wall or a built-in type in which an exchange is buried in a ceiling and a duct is routed to a required room. Two major techniques are known.

For example, as a heat exchange type ventilation fan, a separate type heat exchange type ventilation fan which is embedded in a ceiling of a living room or a dining room is known. This separate type heat exchange type ventilation fan embedded in the ceiling does not open the window, so comfortable ventilation is possible without impairing the cooling and heating effect,
The air-conditioning effect of high insulation can be maintained because the windows are not opened, and it is possible to draw in dirty air in a dining room and exhaust it outside, take in fresh outdoor air, and supply it to the living room. It has an excellent feature that ventilation can be performed without opening a window without substantially impairing a comfortable room temperature by cooling and heating.

As a simpler technique than the above-mentioned heat exchange type ventilation fan, a ventilation fan is attached to one corner of a wall, or a ventilation fan or a ventilation unit is fitted into a part of a window sash, and these are sometimes activated to take in outside air. Such techniques are also known.

[0006]

In the above-mentioned heat-exchange type ventilation fan, it is not only necessary to dispose it on the ceiling, but also the equipment becomes large-scale, and devices such as pipes and heat exchangers are arranged in the space behind the ceiling. There is a need. In particular, there has been a problem that it is not possible to dispose it unless it is determined in advance on the overall plan at the time of design.

[0007] Further, the technique using a ventilation fan is a simple method that can be retrofitted, but requires a wall facing the outer wall, and has a problem in that it hinders the installation of furniture and makes the mounting appearance unsightly. In other words, the installation position of the ventilation fan is at one corner of the wall or at the opening of the window, not only is it difficult to secure the installation position, but also the indoor design is limited, and it interferes with the arrangement of furniture etc. There was an inconvenience in design.

[0008] Further, there is also known a technique of using a movable panel above and below a window sash to provide ventilation by opening and closing the panel (for example, Japanese Patent Application Laid-Open No. 8-277885) and a technique of providing a ventilation unit on the window sash. However, in these techniques, when a 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.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a heat exchange type indoor ventilator which can ventilate the room without changing the indoor temperature condition and which does not give a feeling of strangeness to the indoor design.

Another object of the present invention is to provide a heat exchange type indoor ventilator and a mounting method which can be unitized and can cope with a large-scale remodeling or a change in layout.

[0011]

The object of the present invention is to provide a heat exchange type indoor ventilation device according to claim 1, comprising a curtain box arrangement space, a window arrangement space, an electric shutter box and an outdoor hood arrangement space, The problem is solved by disposing a heat exchanger and a supply / exhaust device in any of the spaces.

Further, in the heat exchange type indoor ventilator according to the second aspect, the upper space of the curtain box arranged on the indoor side, the upper space of the window connected to the upper space of the curtain box arrangement, and the upper space of the window arrangement. This problem can be solved by providing an electric shutter box and an outdoor hood arrangement space that is continuous with the space and arranged outside the room, and that the heat exchanger and the supply / exhaust fan are arranged in any of the above spaces. In this specification, “space” in a curtain box arrangement space, a window arrangement space, an electric shutter box, and an outdoor hood arrangement space is also used as a word indicating an arrangementable position.

According to the first and second aspects of the present invention,
In the case of a living room, since the upper side room space of the window, which is an opening set on the outer wall surface, is necessarily used, it does not conflict with the arrangement position of furniture etc. and it is possible to solve aesthetic problems. .

Further, since the shutter is arranged at the hood position of the air supply / exhaust duct on the outdoor side because it is provided above the window,
The shutter arrangement portion can be used also as the hood arrangement position, and the appearance is not impaired.

Further, since the window itself does not need to be touched at all, all of daylighting, shielding, crime prevention, and ventilation (planned ventilation) can be unitized by the opening of the window. For this reason, when a design is changed or remodeled or changed due to a change with the passage of time, replacement is easy, and the degree of freedom in designing a building increases.

Further, since a unit for each window frame can be made, it is possible to manufacture at a factory, and by removing and attaching a unit including a window frame manufactured at the factory at the site, the number of steps on site is reduced, and , It is possible to ensure and guarantee the quality.

At this time, the heat exchanger and the air supply / exhaust fan may be formed separately, and may be arranged in any of the respective spaces. As described above, when the heat exchanger and the supply / exhaust fan are separated, the respective arrangement spaces can be freely selected, so that the design and compactness of the heat exchange type indoor ventilation device can be achieved, and the degree of freedom of design can be increased. It is possible to secure.

Contrary to the above, the heat exchanger and the air supply / exhaust fan may be integrally unitized and arranged in the upper space of the curtain box arrangement on the indoor side. As a result, the space on the inconspicuous curtain box can be effectively used, and the size of the heat exchange type indoor ventilation device can be reduced. Effective heat exchange is possible even with a narrow window width (between walls). Becomes

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 on the inside of the device, so that the temperature effect on the electric shutter can be reduced and the appearance is excellent.

The above-described heat exchange type indoor ventilation device is preferably formed integrally with the window frame. That is, by being unitized integrally with the window frame, it becomes possible to directly attach the window frame to the opening where the window of the building is formed.
For this reason, by integrating the window frame and the heat exchange type indoor ventilation device, the window itself does not need to be touched at all, so all of lighting, shielding, crime prevention, ventilation (planned ventilation) It becomes possible to unitize. In addition, since each window frame can be made into a unit, it can be manufactured at the factory, and by removing and attaching the unit including the window frame manufactured at the factory at the site, the number of on-site man-hours is reduced, and the finish and quality are secured.・ Guarantees can be made.
