What do you think of the air conditioner liquid pressure gauge? How much pressure does it add?

Answer:

The number corresponding to the pressure in the fluorine 22 pressure gauge refers to the evaporation temperature of fluorine 22 under the corresponding pressure. Any Freon 22 air conditioner operating in a refrigeration environment, the ambient temperature of 25 degrees to 45 degrees, the pressure should be 0.45-----0.6MPa.Outside the red circle, -30 to 350LB/IN2, this is the British unit of force, and the inside is -0.1 to 2.5MPa, this is what we often say pressure, unit is MPa (MPa).Now the table is in the position of no pressure, that is to say, the table pointer is on the 0 bit. Under normal operating conditions of the air conditioner, the meter should point to the 0.5MPa. 0.1MPa is approximately equal to 1.0197 kg / cm, 2 (kg/cm2) =0.987 atmospheric pressure (ATM), that is to say, the normal operating pressure of the air conditioner is 5.0985kg/cm2.
Pressure gauge installed in the liquid inlet and gas tank in the middle, the specific pressure forgotten, and did not go for a long time, it seems to be 2.8, I can not remember
You find a Fo and ask the not good.
