What is the meaning of the full pressure of the fan?
Air static pressure in air conditioning refers to the relative static pressure.
Static pressure is the potential energy per unit volume of gas, is a force, its performance will be gas compression, pressure on the wall.
The hydrostatic pressure at atmospheric pressure is called relative static pressure.
Calculation, the absolute vacuum for the calculation of zero static pressure is called absolute static pressure.
The pressure generated by the irregular movement of air molecules on the wall of the pipe is called static pressure.
