Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a circulation device in a colonnade space in which a lower floor space and an upper floor space communicate with each other, and more particularly to a technology for effectively performing air conditioning in the colonnade space.

[0002]

[Prior Art]

 Conventionally, air conditioning in a colonnade that connects the lower floor space and the upper floor space has been done by installing a large fan at a high place such as the ceiling so that a large fan can provide air regardless of the summer or winter season. It was being blown down.

[0003]

[Problems to be solved by the device]

 However, in such a structure, since the air is blown down from above, the temperature difference between the upper and lower sides of the blow-through space is large, and if the cross-sectional area of the opening space, that is, the blow-through space is large, the air conditioning load is also large. However, air must be circulated by using a large fan, which makes it difficult to properly air-condition the blow-through space.

The present invention is intended to solve such a problem, and an object thereof is to effectively perform air conditioning by energy saving even in a blow-through space having a large cross-sectional area by a rational configuration. It is to provide a circulation device in the blow-through part that can

[0005]

[Means for Solving the Problems]

 The present invention is a circulation device in a blow-through space 3 in which a lower floor space 1 and an upper floor space 2 communicate with each other, and an outlet 5 for blowing air in a direction traversing the blow-through space 3 is provided in a floor portion 4 on an upper floor. A suction port 6 is provided to face the air outlet 5 so as to suck in air from the air outlet 5 to generate an air curtain, and the air blow-through space 3 is partitioned by the air curtain. To do.

[0006]

[Action]

 As described above, the air outlet 5 is provided on the floor 4 on the upper floor so as to blow out the air in the direction crossing the blow-through space 3, and the air is sucked from the air outlet 5 so as to face the air outlet 5 to generate an air curtain. By forming a suction port 6 for making the blow-through space 3 partitioned by the air curtain, even in the blow-through space 3 having a large cross-sectional area, the air blown out from the blow-out port 5 of the floor part 4 on the upper floor can be distributed. The air curtain is formed by sucking air from the suction port 6 facing the air-conditioning chamber, and the air curtain divides the blow-through space 3 into a small space. In such a small space, air conditioning can be performed with energy saving, and air-conditioning air circulation is also possible. It is designed to be able to perform effective air conditioning.

【Example】

 Inside the house, an opening is formed on the outdoor wall 7 side in the floor part 4a on the second floor as the floor part 4 on the upper floor and the floor part 4b on the third floor, and at the opening, the lower floor space 1 and the upper floor. A blow-through space 3 that communicates with the space 2 is formed. Further, on the side of the blow-through space 3 of the floor portion 4a on the second floor and the floor portion 4b on the third floor, there is provided an outlet 5 for blowing air in a direction traversing the blow-through space 3. Ducts 8 are arranged on the floors 4a and 4b of each floor, and these ducts 8 are communicated with a blower 9 through a blowout duct 10. The outdoor wall 7 is constructed by holding a glass window 12 by a sash frame 11. The sash frame 11 is formed with a suction port 6 facing the air outlet 5 on each floor. The suction port 6 is in communication with the blower device 9 via an intake duct 13. A louver (not shown) for opening and closing is provided at the outlet 5 and the inlet 6 on each floor so that the outlet 5 can be opened and closed. An outlet 14 is formed on the first floor near the outdoor wall 7.

As described above, the air outlet 5 that blows out the air in the direction crossing the blow-through space 3 is provided in the floor portion 4 on the upper floor, and the air from the air outlet 5 is sucked by facing the air outlet 5 and injecting the air. -By forming the suction port 6 for generating a curtain and partitioning the blow-through space 3 with the air curtain, even in the blow-through space 3 having a large cross-sectional area, it was blown out from the blow-out port 5 of the floor 4 on the upper floor. Air is sucked from the suction port 6 opposite to this to form an air curtain, and the air curtain divides the blow-through space 3 into a small space. Air-conditioning is performed in such a small space with energy saving. Well, the air-conditioning air can be circulated to achieve effective air-conditioning. By blowing circulating air to the glass window 12, the dew condensation on the surface of the glass window 12 can be blown off.

FIG. 2 shows a use state. In the summer, as shown in FIG. 2A, the outlet 5 on the second floor and the inlet 6 facing the outlet 5 are used by opening the louver or the like. That is, the pressure air from the air blower 9 is circulated as shown by the arrow, and the space in the shaded area on the first floor is blocked from the other blow-through space 3 by an air curtain, and the space on the first floor is partitioned in this way. In this way, the air conditioning is performed in order to save energy and improve the circulation efficiency of the air conditioning on the first floor. In the winter daytime, as shown in Fig. 2 (b), the outlets 5 and 14 and the inlets 6 and 6 on each floor are used, and air is blown out from the outlet 14 on the floor on the first floor. The air from the air blower 9 is circulated as shown by the arrow in Fig. 2 (b), and the warm air that tends to stay in the ceiling and the warm air near the outdoor wall 7 can be used for heating the first floor. In such a case, the air outlet 14 may be provided with an air conditioning function so that, for example, warm air is blown from the air outlet 14 at night in winter to suppress the downflow of cool air along the outdoor wall 7.

[Effect of the device]

 In the present invention, as described above, the air outlet is provided on the floor of the upper floor so as to blow out the air in the direction crossing the blow-through space, and the air is sucked from the air outlet facing the air outlet to generate the air curtain. Since the air inlet is formed and the blow-out space is partitioned by the air curtain, the air blown out from the blow-out port 5 on the floor of the upper floor can be blown from the suction port opposite to it even in a blow-through space with a large cross-sectional area. The air curtain is sucked in to form an air curtain, and the air curtain divides the blow-through space into a small space.In such a small space, air-conditioning can be performed with energy saving and air-conditioning air can be circulated. There is an advantage that it can be done.
