Easy to do. Since the rectifying body 3 is divided into 3a and 3b on the left and right, the rectifying body 3 can be removed and attached more easily.

In addition to providing the resin frames 20, 21 and 22, and the inner window 2 using the frame and the double glazing 24, this fitting also provides the ventilation portion 5 and the intermediate layer of the outer window 1 as shown in FIG. Air flows indoors and outdoors through the ventilation portion 25 of the inner window 2 and the inner window 2 (the arrows in the figure indicate the air flow), and at that time, the air flows through the intermediate layer 4 on the inner side surface of the outer window 1 and the outer side of the inner window 2. By detouring along the side surface, the heat that escapes from the room to the outside is recovered, or the heat that enters the room from the outside is discarded to the outside, which causes heat transfer in the direction opposite to the direction in which the air flows. Is hindered and exhibits a very good heat insulating effect.

Explaining the case of winter, the indoor pressure is adjusted to a negative pressure by a ventilation fan or the like, and as shown in FIG. 2, the air flows from the outdoor to the indoor of the fitting. The cold air (outside air) flowing in from the ventilation portion 5 of the outer window 1 changes the direction of the flow downward by hitting the rectifying body 3, and then the inside of the glass 14 of the outer window 1 having a low temperature and a strong downward flow. It descends while being attracted to the flow along the side surface. After that, the cold air flows to the bottom of the intermediate layer 4 and then turns back, is warmed by transferring the heat in the room from the glass 24 of the inner window 2, rises along the outdoor surface of the glass 24, and during this time, it rises from the glass 24 to the outside. The heat that escapes to the glass is recovered by the flow of air. Further, when the window receives solar radiation, the solar heat can be acquired while the air flows through the intermediate layer 4 along the inner side surface of the outer window 1 and the outer surface of the inner window 2 in this way. After that, the warmed air flows into the room through the ventilation portion 25 above the inner window 2. Even when the air passes through the ventilation portion 25, the heat of the ventilation breath 6 and the upper frame 20 heated by the heat in the room is recovered by the air flow. By taking the warmed air into the room, the recovered heat can be returned to the room.

In this way, by detouring the inside of the intermediate layer 4 along the outer window 1 and the inner window 2, the solar heat can be acquired, and the heat transferred from the room to the outside can be recovered by the air flow. By returning it to the room, there is almost no heat loss from the room to the outside, which hinders the heat transfer from the indoor side to the outdoor side, which is the direction opposite to the direction in which the air flows, and provides extremely high heat insulation. At the same time, the outside air can be warmed and taken into the room, so that the heating load can be suppressed.

In the summer, the pressure inside the room is adjusted to positive by using a ventilation fan, etc., so that the air flows from the room to the outside, contrary to the winter. The air (inside air) that has flowed out from the ventilation portion 25 of the inner window 2 to the intermediate layer 4 hits the rectifying body 3 and changes its flow downward. Flows downward. After that, the air is folded back at the lower part of the intermediate layer 4, and the heat of the glass 14 of the outer window 1 is transferred to rise along the indoor side surface of the glass 14 of the outer window 1, and during this time, the air enters the room from the outside through the glass 14. The incoming heat and solar heat are recovered by the flow of air. After that, air is discharged to the outside through the ventilation portion 5 of the outer window 1. Then, when the air is released to the outside, the heat recovered from the glass 14 and the like and the solar heat are discarded to the outside. By recovering the solar heat and the heat transferred from the outside to the room by the air flow and discarding it outside the room, the acquisition of the solar heat can be suppressed, and the direction from the outside to the inside of the room is opposite to the direction in which the air flows out. Since heat transfer to is hindered, an excellent heat insulating effect can be exhibited, the room can be kept cool, and the cooling load can be suppressed.

As described above, the present fitting includes an outer window 1, an inner window 2, and a rectifying body 3, and has a ventilation portion 5 leading from the outdoor space to the intermediate layer 4 between the outer window 1 and the inner window 2. The inner window 2 has a ventilation part (ventilation breath) 6 at the upper part, the ventilation part 6 has ventilation holes 7a and 7b on the outdoor side and the indoor side, and the rectifying body 3 has a ventilation part of the inner window 2. It is detachably attached to the outdoor side of No. 6, is located on the outdoor side of the vent 7a on the outdoor side of the ventilation unit 6, communicates with the outdoor side, and air is unidirectionally along the inner side surface of the outer window 1. Flows, folds back at the end of the intermediate layer 4, communicates with the room, and air flows in the other direction along the outer surface of the inner window 2 to recover the heat escaping from the room to the outside, or from the outside to the room. By disposing the incoming heat to the outside, it is possible to reduce the inflow and outflow of heat from the windows and reduce the heating and cooling load. Since the rectifying body 3 is detachably attached to the outdoor side of the ventilation unit 6 of the inner window 2, the rectifying body 3 can be easily installed without making a hole in the frame 19, and the rectifying body 3 can be easily installed. Cleaning and maintenance can be done easily by removing it.
In this fitting, the inner window 2 may be installed later in the existing window opening, and in that case, the inner window is formed by attaching the rectifying body 3 to the outdoor side of the ventilation unit 6 of the inner window 2. If 2 is attached, the attachment of the rectifying body 3 is completed, and the work of separately attaching the rectifying body 3 is not required, so that the construction is easy.
Further, in this fitting, the rectifying body 3 is divided into a plurality of parts in the left-right direction, and the divided rectifying bodies 3a and 3b are individually detachable, so that the rectifying body 3 can be removed and attached more easily.
Further, in this fitting, the rectifying body 3 is detachably attached to the pedestal 27 attached to a part of the plurality of vents 7a, 7a, ... The rectifying body 3 can be easily mounted by using the original vents 7a, 7a, ... Without drilling a new hole for mounting the fluid 3.
