TABLE 3 test results of different projection distances of the third and fourth straight lines on the preset plane

Therefore, when the distance L2 is less than 10, the efficiency is low when the distance is overlapped (the upper air duct and the lower air duct are overlapped too much, so that the air outlet space is small); from L2 to L2 to 150, the fan efficiency is gradually increased, when L2 is greater than 150, the fan efficiency is not obviously increased, the continuous increase can cause the front and rear width of the air conditioner to be increased, the appearance is influenced, and finally, the L2 data can be selected from 10-150 according to the requirement of the appearance width.
