Description

Floor diffuser

The present invention relates to a diffuser for supplying cold and warm air flowing under the access floor to the room, and in particular, to freely control the amount of air and the air blown out into the room to reduce the cooling and heating costs, as well as The present invention relates to a floor diffuser for improving air conditioning efficiency.

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 to mean air-conditioning and heating that keeps the indoor atmosphere in a suitable state for the user's life throughout the four seasons through 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 state of the air can be made into cold or 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 and hot air is provided on the wall according to the installation position, and the blowout port for exhausting the air in the horizontal direction, and the ceiling for ejecting the air below the ceiling surface. 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 a space inside the double floor and drawing it into the room through a floor outlet. The air extracted from the floor is mixed with indoor 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.

Therefore, the method of screwing, mechanical press or adhesive, which is the coupling means of the inner guide basket and the guide means is not only complicated but also difficult to disassemble when necessary. There is this.

In the case of Document 2, a housing is installed on the floor and guides the air flowing under the access floor to the room, and an air flow regulating plate or cover plate is installed on the upper part of the housing to diffuse, turn or blow out the air in one direction. It consists of.

In the case of this document 2, the cover plate guides the air to be blown upwards vertically, and the airflow control plate is manufactured in various kinds, and is replaced instead of the cover plate according to the tendency of the air to be blown out. As well as the case of the literature 1, the air blowing direction is already determined, there is a problem that the indoor person can not take out in the desired direction, and there is a problem that can not control and block the amount of air.

In the case of Document 3, the airflow control basket is placed on the indoor floor and guides the air flowing under the access floor to the room, and the air drawn out on the airflow control basket is vortexed to attract and diffuse the indoor air. Consists of the air volume control discharge portion and the guide portion to enlarge the.

In the case of Document 3, the air volume control discharge part and the guide part vortex the air to be blown out to expand the induction and diffusion range of the indoor air. There is a problem that can not be taken out in the desired direction, there is also a inconvenience that must be arbitrarily adjusted and fixed to each of the plurality of blades constituting the air volume control basket is arranged along the circumferential direction when adjusting the amount of air.
