DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] LL Yottan I Part 1 The present invention is a window for a building, particularly a window suitable for an office building. More specifically, a blower is installed inside the double-panel window, and indoor air is exhausted to the outside through the space inside the double-pane window, which has an excellent effect of reducing heat load and improving the thermal environment.

Recently, buildings have been equipped with air conditioning equipment, which keeps the room indoors at 1:00 pm.
Many massagers control the temperature to a constant temperature.

Most office buildings are equipped with this type of air conditioning equipment. This air conditioning equipment controls the indoor temperature at an appropriate temperature for human activity in both summer and winter. Normally, indoor rooms are kept at a uniform set temperature depending on the season.

ところで、建物には必ず窓が設けられている。By the way, all buildings have windows.

In addition, heat loss or heat gain from the window is greater than from the outer wall of the membrane. Further, since glass is easily affected by the outside temperature, the glass temperature is higher than the set room temperature in summer and lower in winter, and the living environment near the window deteriorates due to long-wavelength radiant heat from the glass surface. When solar radiation transmitted through glass is added to this, the living environment becomes even worse. Therefore, even if the room temperature is kept constant with air conditioning equipment, the living environment near the window is worse than in areas far from the window. Taking this into consideration, the set temperature in summer is set low and the set temperature in winter is set high. □
Taking measures such as '\' will increase energy consumption for air conditioning. Therefore, various efforts have been made to reduce heat loss or heat gain from windows. The easiest thing to do is to install blinds on the windows. Furthermore, it is well known that improved versions of the windows themselves have appeared, such as double-glazed windows with two panes of glass installed inside and outside, and double-glazed windows with built-in blinds that have blinds installed in the space of the double-paned windows. Double-glazed windows with built-in blinds are the most efficient, and can reduce heat loss to about 1/4 when the temperature is low in winter compared to windows with blinds.

However, these methods, such as installing blinds, double-glazed windows, and double-glazed windows with built-in blinds, are primarily aimed at reducing heat loss or heat gain, and are not intended to improve the thermal environment near the window. Ta. Therefore, for example, when there is sunlight, the temperature of the indoor glass of blinds or double-glazed windows with built-in blinds installed on the indoor side can be more than 10'C higher than room temperature in extreme cases, and the long-wavelength radiation from now on. Therefore, residents near the window feel extremely hot. If the long-wavelength radiation environment near windows can be improved, room temperature settings can be relaxed, resulting in significant energy savings. It is said that 10% of energy consumption for air conditioning can be saved by adding l'oi to the set room temperature.

Taking these into consideration, the present applicant proposed a double-glazed window in which indoor air is exhausted to the outside through the space between the inner and outer glass (Japanese Patent Application No. 57-220330). Since air is brought into contact with both sides of the glass on the indoor side, the temperature of this glass can be brought close to the indoor temperature. Therefore, long-wavelength radiation from the window member is alleviated, and the thermal environment near the window is improved. Furthermore, the air passing between the windows collects and eliminates the heat just before it enters the room, such as solar heat absorbed by the blinds, significantly reducing the heat load.

Furthermore, in buildings such as buildings where a large number of people reside, the required exhaust volume per person is regulated, and the conditioned air inside the room is wasted by some means to be discharged outside. Windows that use the space of double-glazed windows to exhaust indoor air to the outside through the space (hereinafter referred to as ventilation windows) use the window to exhaust air, so they cannot satisfy this exhaust volume regulation. Not only that, but the exhaust function can be used to reduce the heat load from the window and improve the thermal environment near the window, which is extremely superior, and it also helps reduce the need for air conditioning duct equipment.

If you live in a room with many windows, the noise from the blowers in each window will overlap, making the noise quite disturbing. There is also an exhaust vent outside the room.
Since this forms an air flow path leading to the indoor intake port, there is a risk that external noise may enter the room through this flow path.

An inlet is provided on the indoor side of the frame member, an exhaust port is provided on the outdoor side, and a flow path is provided from the inlet to the exhaust port through the space of the double-panel window, and a blower is installed in this flow path. Since it is installed, the air inside the room can be exhausted to the outside through the space by the blower and can be exhausted by the window body. Moreover, since the air inside the room passes through the space of the double-paned window during exhaust, the glass on the indoor side comes into contact with the air inside the double-sided window and approaches the indoor temperature. Cold radiation is eliminated and the thermal environment near the window is improved.
