Technical field
The utility model relates to air conditioner ventilation apparatus fields, and in particular to outlet air vocal imitation skill.
Background technique
Air diffuser is the air outlet of air-conditioning or ventilation, exactly allows air outlet air-out direction to be divided into multidirectional flowing, is commonly used in
The air outlet setting in the large area such as hall place is evenly distributed so as to fresh air, convenient for the rapidly and uniformly mixing of air, will not produce
The wind speed of raw part is excessive, and the major function of air diffuser is to change air movement direction, keeps air velocity, enables air to fast
Speed mixes with room air or reaches somewhere, and in air-conditioned room, the air and room air of air diffuser discharge carry out caloic friendship
Necessarily cause the flowing of room air after changing, and different air flow conditions has different air-conditioning effects, thus diffusing
The shape and structure of device can make to be formed in conditioned area than faster, uniform stable air velocity, then passing through helical form
Channel solves the acceleration of air-flow and changes the direction of air-flow come the mixing efficiency for improving room air to be that we will solve at present
The technical issues of.
