Description

Air supply system of floor ejecting air conditioning system

The present invention relates to an air supply device of an Under Floor Air-conditioning (UFAC) system for ejecting air from the floor into the room.

In general, the Under Floor Air-conditioning (UFAC) system is to eject the air from the floor air-conditioned in the air conditioner, unlike the conventional ceiling air conditioning. Therefore, the floor spray air conditioning system can handle local loads around the occupants and the working environment, which is advantageous in terms of thermal efficiency and control and can concentrate intensively on the living area. Or it is higher than other air-conditioning systems which eject air-conditioning air from the side wall of the room.

In particular, the floor ejection air conditioning system can reduce unnecessary heat load and requires low air conditioning power, making it suitable for air conditioning systems such as large halls, theaters and churches with high ceilings, and is very effective for energy saving. to be. In addition, it is expected to be applied to new buildings such as large halls, theaters, and churches with high ceilings because it has excellent responsiveness to changes in indoor structure and load characteristics.

However, the air supply system of the floor ejection air conditioning system for ejecting the air conditioning treated by hot or cold air into the room has a function of delivering the air conditioning treated air to a desired place at a predetermined speed and swirl flow strength. The air supply device should be designed so that the air supply of the air supply device can maintain the flow toward the exhaust port while the air circulated from the air supply means surrounds the occupant in the form of a swirl stream.

In particular, since the air supply system of the floor ejection air conditioning system is installed on the floor, it must be designed so that impurities do not enter the air supply port and the air supply port does not obstruct traffic, and the air supply device is installed close to the occupants. Although the air being blown out more in contact with the occupants, it is advantageous in terms of the efficiency of the heat source equipment. However, since the air conditioning directly reaches the indoor living area without the buffer zone, the air speed is sufficiently increased so that the occupants do not feel uncomfortable by the draft of the air conditioning. It should be reduced (typically below 0.15 m / s) to reach the living quarters.

In addition, the air supply system of the floor ejection air conditioning system should be firmly manufactured to support a certain load, and the width of the air supply should be made 7mm or less to prevent the high heels of shoes or other small objects from falling out. do.

If the air supply temperature of the air conditioner and the room temperature are different, different blocks are formed by the temperature difference, and thus the air flow shows different characteristics according to the temperature difference. That is, in the floor blowing air conditioning system, it is preferable to eject the air-conditioned air as close to the vertical as possible due to the flow characteristic of the cold air to the lower side when cooling, and to the surroundings due to the flow characteristic of the hot air to the upper side when heating. Since it is desirable to diffuse widely, it is desired to develop an air supply system for a bottom ejection air conditioning system in which the airflow dispersion angle is adjusted according to a cooling and heating method.

In the description of the present invention, the swirl flow refers to the flow of air conditioning air generated when the air passage of the air inlet formed in the air supply means is inclined, and the swirl flow attracts the surrounding air. It has the property of spreading the airflow distribution over a wide area. And, the number of revolutions representing the strength of the swirl flow means the ratio of the tangential momentum flux to the axial momentum flux.

The present invention has been made in consideration of the above various conditions, and an object of the present invention is to control the intensity of the air conditioning air sprayed through the air outlet, and at the same time, to control the diffusion angle of the air conditioning air is sprayed bottom air conditioning system To provide a supply of air.

Another object of the present invention is to provide an air supply system of the floor jet air conditioning system that can easily control the room temperature according to heating or heating.

Still another object of the present invention is to provide an air supply device for a floor ejecting air conditioning system that can improve energy efficiency and can comfortably maintain indoor air conditioning.

In order to achieve the above object, the air supply system of the bottom ejection air conditioning system according to an embodiment of the present invention is provided with a first air supply means for discharging while turning the air conditioning, and rotatably disposed under the lower plate of the first air supply means A second air supply means for discharging the air conditioning and at the same time to block the air outflow of the air conditioner when the indoor air discharge of the air conditioner is unnecessary, and the through hole 22 in the center so that the first and second air supply means are disposed. And guide means for guiding the swirl flow discharged through the first air supply means in a vertical direction, and air conditioning air introduced by being coupled to the cylindrical body of the guide means is supplied to the outside and inside of the first and second air supply means. And a guide basket in which a plurality of air-conditioning air inlets are formed to guide the vertical through-holes of the mechanism and the guide means.
