Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.
The decrease of the air output is related to the increase of the system resistance to the air flow, wherein the system resistance is partly from the flow equalizing plate and partly from the vortex, and if the air flow speed is faster and the air flow direction is more irregular and uneven, the vortex is easier to form, namely the size of the vortex is influenced by the arrangement of the flow equalizing plate. In summary, in order to increase the air output, consideration must be given to how to reduce the system resistance to which the air flow is subjected, that is, consideration must be given to the structural arrangement of the flow equalizing plate, and the air outlet speed of the air conditioner is made more uniform by comprehensively considering the three factors of the opening pattern, the installation angle and the installation position of the flow equalizing plate.

The utility model discloses a mode of simulation synthesizes more circular port, quad slit and long waist hole three's good and bad, and the conclusion that reachs is that the trompil shape that adopts the great long waist hole of trompil area as the board that flow equalizes more has profitable effect than circular port and quad slit. In addition, the opening size of the flow equalizing plate needs to be set within a reasonable range to achieve the expected effect: if the opening area of the flow equalizing plate is too small, the effective air inlet area of the flow equalizing plate is small, and the effective air outlet quantity is influenced; if the open area of the flow equalizing plate is too large, the sheet metal strength and the flow equalizing effect of the flow equalizing plate can be influenced. The utility model discloses a simulation calculation finally reaches the conclusion: the length of the long waist hole is 50-70mm, and the width is preferably 10-20 mm. With the tradition in the flow equalizing board the air current be cut apart into a lot of long and narrow runners different, the utility model discloses the flow equalizing board trompil is reasonable, and the runner area is great relatively, and effective air inlet area is big, has created the advantage for the effective air output of increase to a certain extent.
