基于涡动气流不适率的空调送风方式研究与应用

Research and application of air supply mode for air-conditioning based on draft rate

基于涡动气流不适率及康达效应,采用倾斜微孔弥散射流出风方式,实现微孔层流柔和送风,同时缓解冷空气过早落地问题。采用间隙附壁引流,搭载智能自旋转式导风板,实现广范围柔和送风,有效保证房间各区域舒适性;在同转速下,柔风模式时的制冷量降低14.8%,涡动气流不适率为10%,相比常规送风模式降低25.4%;在同风量下,柔风模式的涡动气流不适率为12.5%,相比常规送风模式降低22.9%;柔风模式的扫风范围比常规模式更广,有效提升送风舒适性。

Base on DR (draft rate) model and Kangda wall flow effect, the inclined micropores are used to disperse the outgoing air, which achieves gentle air supply of microporous laminar flow and alleviates the problem of premature landing of cold air. Using wall flow of clearance equipped with intelligent self-rotating air deflector, it achieves a wide range of soft air supply, which ensures the comfort of all areas of the room. Under the same rotation speed, for the soft wind mode, the cooling capacity is reduced by 14. 8%, and the draft rate is 10%, which is lower than that of the conventional air supply mode by 25.4%. Under the same air volume, for the soft wind mode, the draft rate is 12. 5%, which is lower than that of the conventional air supply mode by 22.9%. The sweeping range of soft wind mode is wider than that of conventional air supply mode, which effectively improves the comfort of air supply.
