The compressor.
The refrigerant
Refrigerant works by absorbing heat from inside the refrigerator or air conditioning system and carrying it outside. As the refrigerant evaporates, it cools the air inside the system. The refrigerant then condenses back into a liquid, releasing the heat outside, and the cycle repeats to keep the space cool.
Aside from circulating the refrigerant and PAG oil, it also changes the refrigerant from a low pressure vapor to a high pressure vapor, thus allowing the superheat to occur, and the heat exchange vital to the function of the AC system.
To add refrigerant to your air conditioning system, you will need to locate the service valves on the unit, connect a refrigerant charging hose, and slowly add the appropriate amount of refrigerant according to the manufacturer's specifications. It is important to follow safety guidelines and regulations when handling refrigerants.
System is low on refrigerant.
For starters, you'll get insufficient cooling from your system. Refrigerant changes states from liquid to vapor and back again in order to achieve cooling, and the system pressure is balanced to facilitate this - excessive refrigerant makes it much more difficult to do this. Additionally, your system will generate excessively high pressure, which will ultimately damage or destroy system components.
used as cooling and freezing agent
The compressor fan in an air conditioning system helps to cool down the refrigerant gas by compressing it, which increases its pressure and temperature. This allows the refrigerant to release heat outside the system, making the air inside the building cooler.

With a refrigerant recovery and recycling machine.
You can add air conditioning refrigerant to your 2000 F1 50 pickup truck air conditioning system through the low pressure port. The low pressure port will be on the top of the air conditioning compressor.
