Description

The present invention relates to a method of installing a circulator that generates an air flow by a cross flow fan.

When the heating operation or the cooling operation is performed by the air conditioner, cold air and warm air are mixed in the room. Warm air collects above and cold air collects below, so the air warmed by the heating operation collects near the ceiling surface, and the air near the floor surface where there are people does not warm up even if the heating operation is performed. Sometimes not. Therefore, in order to warm the air near the floor surface, it is necessary to increase the intensity of the heating operation, the energy consumption increases, and the air conditioning efficiency decreases. Further, since the air conditioner is often installed on the wall surface at a height close to the ceiling surface, warm air near the ceiling surface is taken in and the cooling air is blown out during the cooling operation. Therefore, if the cooling operation is performed with an operating intensity that matches the temperature of the air taken in, the air near the floor surface will be cooled more than necessary, and the air conditioning efficiency will decrease. In the indoor space that straddles the upper floors and the lower floors, the temperature difference between the upper part and the lower part of the space becomes remarkable, and the air conditioning efficiency also becomes remarkable.

Further, the airflow blown out from the air conditioner does not reach the space where the falling wall is formed between the space where the air conditioner is installed. Therefore, in order to harmonize the space where the falling wall is formed with the space where the air conditioned device is installed, it is necessary to separately install the air conditioned device.

As described above, the upper part and the lower part of the space straddling the upper floor and the lower floor are spaces in which the temperature distribution is difficult to be uniform. In addition, the two spaces separated by the falling wall are spaces in which the temperature distribution is difficult to be uniform.

In a space where it is difficult to make the temperature uniform with the air conditioner alone, a circulator that transports or agitates the air to make the temperature uniform may be used. Patent Document 1 discloses a circulator that changes the direction of an air flow formed by a cross flow fan with a louver.

The circulator disclosed in Patent Document 1 has a structure in which the air passage itself in the housing blows airflow in parallel with the installation surface, and blows airflow onto the louver to forcibly change the direction of the airflow. Collision of airflow to the louver causes noise. Therefore, the circulator disclosed in Patent Document 1 must be installed at a high place away from the floor surface in order to reduce the noise reaching the vicinity of the floor surface where a person lives. Therefore, the circulator disclosed in Patent Document 1 makes the temperature distribution of two spaces, which is difficult to make uniform with the air conditioner alone, and suppresses the movement of air between the two spaces. It is difficult to install it at the height of the ceiling of the living room for the purpose.

The present invention has been made in view of the above, and an object of the present invention is to obtain a method for installing a circulator in which a circulator is installed so as to maintain quietness and improve air conditioning efficiency.

In order to solve the above-mentioned problems and achieve the object, the present invention is a circulator capable of forming an air flow by a cross flow fan, changing the direction of the air flow outlet for each air passage, and changing the air flow direction. It is the installation method of. In the present invention, the circulator is installed on the wall surface at an intermediate height of the space straddling the upper floor and the lower floor or on the ceiling surface of the lower floor.

The fan 21, casing 22, and straightening vane 231 form a cross-flow fan that blows airflow in a direction intersecting the axis of rotation of the fan 21. The guard portion 233 has a semi-cylindrical shape obtained by cutting a cylinder along an axis, and is punched. The air outside the circulator 100 is taken into the cross flow fan from the suction port 24 through the punching hole. The guard portion 233 may have a grid shape or a net shape.

The air passage portion 2 is rotatably supported by the first support portion 3 and the second support portion 4. The air passage portion 2 has a first rotation position in which an air flow is blown out in parallel with the base plate 1 from one long side 11 side of the base plate 1 in a direction in which the short side of the base plate 1 extends, and the other long side 12 of the base plate 1. It can rotate from the side to the second rotation position where the airflow is blown out in parallel with the base plate 1. When the air passage portion 2 rotates from the first rotation position to the second rotation position, or when it rotates from the second rotation position to the first rotation position, the air passage portion 2 is attached to the base plate 1. It goes through a third rotation position that blows airflow vertically. Note that FIG. 2 shows a state in which the air passage portion 2 is in the first rotation position, and FIG. 3 shows a state in which the air passage portion 2 is in the second rotation position.

FIG. 7 is a diagram showing a method of installing the circulator according to the first embodiment. The circulator 100 is installed on the wall surface 302 of the atrium 301. The height at which the circulator 100 is installed is the intermediate height of the atrium 301. The intermediate height of the atrium 301 is a height in the range of half or more and two-thirds or less of the height of the ceiling surface 305 of the atrium 301 from the floor surface 304 of the first room 300. In the circulator 100, the direction of the air passage portion 2 is set so as to blow out the air flow downward. The wall surface 302 on which the circulator 100 is installed is a wall surface facing the wall surface 303 on which the air conditioner 200 is installed. The first room 300 is connected to the adjacent second room 400. As an example, the first room 300 is a living room and the second room 400 is a dining room. The arrows in FIG. 7 indicate the flow of air.

The first room 300 is located on the lower floor 600, and the atrium 301 is located on the upper floor 700. The first room 300 and the atrium 301 are one space, but the position of the upper surface 201 of the air conditioner 200 is the virtual ceiling surface 306, and the portion below the virtual ceiling surface 306 is the lower floor 600. The portion having a height of the virtual ceiling surface 306 or higher is defined as the upper floor 700. As shown in FIG. 7, when the second room 400 adjacent to the first room 300 exists, the ceiling surface 401 of the second room 400 is extended to the first room 300 to be used as the virtual ceiling surface 306. May be good.

Warm air tends to collect in the atrium 301 located on the upper floor 700, and cold air tends to collect in the first room 300 located on the lower floor 600. That is, the atrium 301 and the first room 300 are two spaces in which the temperature distribution is difficult to be uniform. The circulator 100 sends the warm air accumulated in the atrium 301 to the vicinity of the floor surface 304, and agitates the air in the first room 300 and the atrium 301. Therefore, by installing the circulator 100 by the method of installing the circulator according to the first embodiment described above, the temperature distribution of the first room 300 and the atrium 301 is made uniform during the operation of the air conditioner 200, and the air conditioning efficiency is improved. To do. That is, by installing the circulator 100 by the method of installing the circulator according to the first embodiment, it is possible to suppress the energy consumption due to the air conditioning operation of the air conditioning device 200. Further, since the first room 300 and the second room 400 are connected to each other, the airflow blown out from the circulator 100 and reaching the floor surface 304 also flows into the second room 400. Therefore, the temperature distribution of the air in the room including the second room 400 can be made uniform.

Since the circulator 100 is installed on the wall surface 302 at an intermediate height of the atrium 301, maintenance work can be performed by climbing a stepladder or a step ladder. Therefore, when performing maintenance work on the circulator 100, it is not necessary to build a scaffolding in the room, and maintenance can be easily performed. Further, since the maintenance work of the circulator 100 can be performed indoors, the maintenance of the circulator 100 can be easily performed even at night or in stormy weather.

Since the circulator 100 does not change the wind direction with the louver, the vicinity of the floor surface 304 is kept quiet even if it is installed at the intermediate height of the atrium 301. Further, by installing the circulator 100 at the intermediate height of the atrium 301, the distance to the floor surface 304 is shorter than when it is installed on the ceiling surface 305 of the atrium 301, so that the airflow sent from the circulator 100 is weak. Even so, the airflow reaches the floor surface 304. Therefore, even if the circulator 100 is operated with a weak notch having high quietness, the air conditioning efficiency in the room can be improved.

By installing the circulator 100 on the wall surface 302 facing the wall surface 303 on which the air conditioner 200 is installed, the air flow blown out from the circulator 100 collides with the air flow blown out from the air conditioner 200 and diffuses. Since it becomes easy, the effect of increasing the air conditioning efficiency can be further improved.
