The present invention relates to a turning outlet for the floor, and more specifically, by adjusting the rotation angle of each blade provided in the air volume control basket to disperse the air flow of cold and hot air flowing from the lower space of the access floor, air volume control By vortexing the cold / hot air discharged to the upper part through the blade through the discharge part to expand the range of induction and air diffusion of the indoor air, it is easy to cope with the fluctuation of the indoor load to reduce the cooling / heating cost. Of course, it relates to a floor turning outlet for improving the air conditioning efficiency to keep the room comfortable.

In general, air conditioning in a home or office is to keep indoor air at a temperature, humidity, and cleanness suitable for its purpose, and to remove various dusts and harmful gases. Also known as air-conditioning, it is recognized as meaning air-conditioning and heating that keeps the indoor atmosphere in a suitable state for the user's life throughout the four seasons by cooling in summer and heating in winter. have.

As the most widely used method for indoor air conditioning, an air conditioner is separately installed so that the air condition can be formed into cold / hot air according to its needs, and then various air blowers are used to create the air conditioner. Cool and hot air is blown through the duct to the room, and various types of outlets connected to the duct on the wall, ceiling or floor are provided for blowing the cool and hot air through the room. It is installed.

As described above, the blowout port for blowing the cold / hot air is provided on the wall according to the installation position, and the blowout port for exhausting air in the horizontal direction, and the ceiling outlet, which is installed on the ceiling surface and blows air downward. It is divided into a blowout outlet and a bottom blowout outlet which is installed at the bottom surface and blows air upward.

Conventionally, in the case of an air conditioning system, air supplied from an air conditioner is mainly supplied from a duct of a ceiling of a building through a ceiling outlet so as to supply air and exhaust the air. That is, the air blown out through the ceiling outlet is mixed with indoor air, absorbs all the heat generated in the room, and is discharged to the outside through the exhaust vent in the ceiling. However, because the turbid air moved to the upper part of the ceiling and fresh air supplied from the ceiling are mixed, the airflow reaching the interior is deteriorated and the inflow air is unbalanced due to the partitions and office equipment installed in the room. There is a problem that takes a long time to recover the low and polluted indoor air.

In addition, when cold and hot air is supplied to the room through the ceiling outlet and the wall outlet, it is difficult to control the wind speed, direction, and air volume, so that the air conditioner must be operated separately, and the grille structure of the outlet can be adjusted. If the position of each outlet is installed in the upper, there is a problem that adjustment is not easy.

In order to solve the above problems, recently, a floor air conditioning system is proposed in which air supplied from an air conditioner is supplied upward from a floor of a building.

In other words, the floor air conditioning system is a method of supplying air by utilizing the space inside the double floor and drawing it into the room through a floor outlet. The air drawn from the floor is mixed with the room air to form an indoor temperature, The air absorbed heat from the heating element rises to the ceiling by the flotation effect. The airflow blown out through the floor outlet can increase the stability of indoor airflow by guiding the indoor airflow to the upper part of the ceiling by the flotation effect of the indoor heat source, and the ventilation direction is high because the airflow direction matches natural convection. Contaminated air will be discharged in a short time.

In addition, the floor air conditioning system can reduce unnecessary heat load, and because the air power of the air conditioning is low, the installation of large halls, theaters and churches with high ceilings is not only suitable, but also it is possible to change the indoor structure or change the load characteristics. Excellent responsiveness and effective for saving energy.

When the air supply temperature of the air drawn out through the floor outlet 160 and the temperature of the room are different, different air flows are generated in the room due to the temperature difference. Therefore, it is desirable to blow out the air-conditioned air to the upper part close to vertical due to the flow characteristic of cold air toward the bottom when cooling the room, and to spread the blown air to the surroundings due to the flow characteristic of the hot air toward the top when indoor heating. Do.

However, the conventional floor outlet 160 as described above is difficult to control the airflow dispersion angle according to the air-conditioning method as the induction of indoor air due to vortex and the diffusion range of the air is limited, the air conditioning efficiency is lowered, as well as energy There was a problem in that the cost of waste and air conditioning increased.

The present invention has been made to solve the above problems, by adjusting the rotation angle of each blade provided in the air volume control basket to disperse the air flow of cold and hot air introduced from the lower space of the access floor, By generating vortices in the cold / hot air discharged to the upper part through the blade through the guide part, the induction of indoor air and the spreading range of the air are expanded, thereby easily reducing the cooling / heating cost by responding to the variation of the indoor load. The purpose is to improve the air conditioning efficiency to keep the room comfortable.
