According to the architecture characteristics, USES the nozzle and diffuser air supply modes.
结合建筑特点，选用喷口和散流器送风。
The results show that the diffuser has such advantages as larger induction ratio, low resistance and noise, relatively even air supply, no condensation, simple in structure and low in costs.
测试结果表明，该风口的诱导比大，阻力小，噪声低，送风比较均匀，风口没有结露现象，结构简单，造价低。
