Mainly inside these two laps, freon temperature is what, oh, do not understand, usually the original table, I see the MPa, this is not, thank you!
10Kg/cm - =1Mpa, a kilogram force is one kilogram role in 1CM - surface pressure.The red is the temperature, and the inner ring red is the R22 refrigerant, and the outer red is the R12 refrigerant.Now R12 basically eliminated, R22 shouted to be eliminated, but the cooling effect is good, currently using the mainstream
Black is the pressure gauge, per kilogram / square centimeter, approximately equal to 100 kPa, so it consists of two scales. The pink one is too small to see clearly.
The temperature of Freon refers to the saturation temperature of the corresponding freon refrigerant under this pressure corresponding to the pressure of the outer ring.
