Working principle of suspended ceiling jet unit


2025-09-19

The working principle of a suspended ceiling air conditioning unit is that the airflow flows into the impeller from the axial direction, and then rotates 900 degrees inside the impeller for radial flow. The suspended ceiling air conditioning unit is installed and then discharged from the outer edge of the impeller through the volute shell. The impeller of a centrifugal fan has three types: forward, radial, and backward. Under the same diameter, speed, and inlet conditions, each of these three impellers has a short length. The wind pressure and outlet velocity generated by the curved impeller are relatively large, and its structural dimensions are compact and its quality is small. The working principle of the suspended ceiling air conditioning unit is that the forward impeller, due to its high outlet airflow velocity, converts into pressure energy in the snail light, causing significant losses to the Tongchuan suspended ceiling air conditioning unit, resulting in low fan efficiency.
