Description

{AIR SUPPLY AND RETURN ASSEMBLED DIFFUSER WITH FAN}

More particularly, the present invention relates to a diffuser, and more particularly, to a diffuser having an air supply mechanism and an air exhaustion port formed in a diffuser, a fan and a flap attached to the air supply side to compensate a static pressure of the duct, The present invention relates to a fan-equipped air supply / exhaust unit integrated type diffuser capable of freely using and distributing air supply direction and air volume by providing a flap on the air supply mechanism side, and adjusting the air supply direction and air volume by a user's choice.

Generally, a district cooling or electric cooling system installs a cooler in a machine room or an outdoor room, and then supplies cooling through a duct or a refrigerant pipe.

Among these methods, a duct type cooling system installs a diffuser for supplying and exhausting air to the ceiling of each room to supply cooling air through the duct, and each diffuser requires the same number of ducts.

In the conventional duct type cooling system, air supply is provided by installing a diffuser for supplying and exhausting air into the ceiling space of each room and connecting the ducts. A duct for cooling supply must be connected to the diffuser for the air supply, and a diffuser for return (return) for recovering air in the room is required separately.

Generally, the air is recovered by using a diffuser for exhaust, cooled through a cooler, and then supplied to the room using a diffuser for supplying air.

There are ceiling sealing return type and return duct type as a method of recovering indoor air. Ceiling sealing return system installs exhaust diffuser only on the ceiling finishing material, so that the entire interior space of the ceiling serves as air channel, and the room air is recovered to the air conditioner by forming negative pressure by rotating the blower of the air conditioner.

On the other hand, in the case of the return duct type, a separate duct for returning is installed in the same manner as the duct for the supply duct, and is recovered by the air conditioner. Both of these require an exhaust diffuser, and each chamber is equipped with one or more pairs of air diffusers and exhaust diffusers.

In order to connect these diffusers and ducts, a connection method using a flexible duct is generally used. In the installation process, the diffuser and the duct are installed respectively, and the connection is finished using the flexible duct, and the frictional loss of the flexible duct causes the increase of the static pressure loss.

Furthermore, when the number of zones or chambers requiring cooling is increased, the number of diffusers is increased in proportion to the number of ducts, thereby increasing the supply air volume and the static pressure loss for a large number of ducts. This increases the size of the blower or increases the number of revolutions because it is transferred to the blower load of the air conditioner. Also, the noise generated increases due to the increase in the number of revolutions, which causes a decrease in user satisfaction.

In recent years, the installation of fire-extinguishing facilities, conduits, etc. is complicated inside the ceiling. Therefore, it is necessary to avoid interference with facilities inside the ceiling in order to install a duct for cooling. This limits the installation to the duct, which results in a deterioration in the workability and a rise in cost and poor quality.
