It is maintained through the use of a compressor in a graduated cylinder
When vapor refrigerant is pulled out of a cylinder the vapor is reduced and the liquid boils to replace the vapor that has left the cylinder.
Add refrigerant vapor on the low side of the system ,the compressor raises the pressure of the refrigerant on the high side of the system and lowers the pressure on the low side
lose the heat from the refrigerant
The reason is that as the liquid evaporates in the tank and it cools it down and the vapor pressure (pressure in tank) is reduced and the evaporation rate decreases. Many refrigeration repair men have a bucket big enough to put their tank in and add hot water to keep the tank warm and get the freon to evaporate faster to speed up their project.

Lighter, as the refrigerant is boiled off, and colder, as it has absorbed heat, and has a lesser pressure to reflect the current temperature / pressure relationship for the type of refrigerant

Damaged refrigerant
comparing the cylinder pressure and the temperature to a pressure-temperature chart.
The refrigerant cylinder is heated in a tub of water to no more than 90 degrees F. Electric heating blankets manufactured for this purpose may also be used.
go to a jobber or online and find a pressure relation to refrigerant chart. it tells you at what temp.,and pressure the designated refrigerant is by number,,i;e;12,22,5o2 etc.
