Detailed Description
The inventor researches and discovers that the space of the L-shaped building corridor needs to be supplied with air, and the space limit of two mutually perpendicular planes needs to be considered. If the air supply mode of the common air opening is still adopted, the air flow blown out from the air opening is limited by a vertical direction surface or a horizontal direction surface corresponding to an angle of 90 degrees of a building space, so that one side is easy to be windy, the other side is windless, the air flow organization cannot be reasonably planned, and the poor ventilation effect, discomfort of personnel and the like in the L-shaped building are caused. The original air blown out by the air diffuser is radially emitted to all directions, the induction rate is high, and the jet flow with high momentum is rapidly diffused. There is currently no suitable diffuser configuration for air delivery in an L-shaped building space. The air supply device in the building corridor provided by the invention is particularly used for an L-shaped building corridor space, and has a remarkable ventilation improvement effect. In addition, the L-shaped building corridor provided by the invention means that the planar shape of the building corridor is L-shaped. Other architectural designs, similar to L-shapes, are also within the scope of the present invention for air delivery devices.
The non-resistance square region (i.e. low Re number) referred to in the present invention means that the flow state of the gas flow can be divided into a laminar region (Re <2000, the resistance coefficient is only related to Re), a critical transition region (Re ═ 2000-4000, the resistance coefficient is only related to Re), a turbulent smooth region (Re >4000, the resistance coefficient is only related to Re), a turbulent transition region (the resistance coefficient is related to Re and roughness), and a resistance square region (the resistance coefficient is only related to roughness). The resistance coefficient of airflow in the resistance square region is independent of Re, and the on-way resistance is in direct proportion to the square of the speed; the air flow characteristics in the non-resistance square region are mainly influenced by Re, and the air supply standard based on the resistance square region cannot be applied to the air supply characteristics in the low Re number state of the invention at present.
