Description

Air outlet device and air conditioning system using same

The present invention relates to an air outlet device and an air conditioning system using the air outlet device, in particular to an air outlet device and an air conditioning system having a better airflow diffusion effect.

With the evolution of the environment and living habits, people spend more and more time indoors. In order to increase the comfort of the indoor environment, the air conditioning system has become a necessity in today's life.

The air conditioning system has a heat exchange module, and the air is sent to the room through the heat exchange module and then by the fan, the air duct and/or the air outlet. If further consideration is given to saving energy, how to uniformly distribute the airflow generated by the air conditioning system to all corners of the room, avoiding the wind flow being concentrated in a certain area and being unable to be transmitted to the user's location, and the dead angle of the air conditioner is generated, resulting in the indoor temperature distribution not being Both have also become important issues.

A conventional air conditioning system is shown in Figure 1. There is a space between the floor 91 of the building and the light steel frame ceiling 92. The fan 11 is suspended in the floor 91 and disposed in the space. The light steel frame ceiling 92 is provided with an air outlet 12, between the fan 11 and the air outlet 12. The air duct 13 made of a heat insulating material is connected. With this, The wind flow generated by the fan 11 can be distributed to the distal end through the air duct 13 and then blown out through the air outlet 12. In addition, a single fan can also extend out of a plurality of air ducts and are respectively connected to a plurality of air outlets (not shown) so that the wind flow can be distributed to a plurality of appropriate positions in the indoor space.

However, the ceiling of the indoor space is different in height and space. Taking cold air as an example, in general, the most comfortable wind speed that the cold air blows to the human body is about 0.5 meters per second. Therefore, in the configuration of the air conditioning system, it is necessary to consider the amount of air volume that can be generated by the fan, the number of air outlets, and the caliber. Etc. to produce a suitable wind speed. In addition to the wind speed, the flow field generated by the wind flow through the diffuser structure of the air outlet also needs to be considered. Taking Fig. 1 as an example, the wind flow immediately below the air outlet 12 is the strongest, and the farther away from the outer side of the air outlet 12, the wind flow will be significantly weakened. It is conceivable that a user located directly below the air outlet 12 may feel uncomfortable because of the cold air flow, but other users who are not directly below may not feel the wind flow and feel that the indoor temperature is too high, which is the air conditioner. Improper configuration results in uneven indoor temperature distribution.
