How to judge the fan left and right rotation?
Fan related to the system of energy transmission and distribution, building energy is a very critical part
The No power fan is the use of natural wind and indoor and outdoor temperature difference caused by air heat convection, to promote the turbine rotation to the use of centrifugal and negative pressure effect of indoor fresh air is not fresh
The main structural components of the fan are impeller, housing, air inlet, bracket, motor, pulley, coupling, silencer, transmission (bearing) and so on.
From the motor side of the face, where the impeller in accordance with the clockwise rotation are called "right whirlwind" to the right; the other hand, is the "left fan" to the left.
According to the National Air Conditioning Equipment Quality Supervision and Inspection Center for many years the fan test shows that many fans in the rated operating conditions are problems, so the need to strictly in accordance with product standards require the production and manufacture of fans.
