You cool it and run it through a metering devise.
Air conditioning works by having the refrigerant undergo changes of state of the refrigerant between a liquid and a vapor, and also through heat exchanges, where heat is absorbed by the refrigerant, and is then exchanged to the ambient air both in the condenser and evaporator. In order for the heat absorbed by the refrigerant to be able to be exchanged to the ambient air, the temperature of the refrigerant must be significantly higher than that of the ambient air. Compressing the refrigerant into a high pressure vapor (which the compressor does) increases the heat of the refrigerant, as, when under high pressure, the molecules rub together more frequently, thus generating additional heat to the heat already absorbed by the refrigerant. This facilitates the heat transfer necessary for the proper performance of an air conditioning system.
The condenser helps to condense the refrigerant vapor into a liquid state by removing heat. It also increases the pressure of the refrigerant, preparing it to enter the coil as a high-pressure liquid. Additionally, the condenser helps to release any remaining heat energy from the refrigerant before it enters the coil to complete the cooling process.
The pressure and the specific refrigerant properties determine the temperature at which a refrigerant vaporizes. As pressure increases, the boiling point of the refrigerant also increases. Different refrigerants have different boiling points at different pressures.

The function of the condenser is to release heat from the refrigerant, causing it to condense from a gas to a liquid state. This process increases the pressure of the refrigerant.
Low air conditioner pressure typically indicates a refrigerant leak in the system. This can lead to reduced cooling efficiency or complete failure of the air conditioner. It is important to have the leak repaired and the refrigerant refilled by a professional HVAC technician.
what happens when refrigerant enters the condenser
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
Refrigerant pressure decreases in a refrigerant cylinder while charging with vapor because vapor has a lower density compared to liquid refrigerant. As vapor is introduced into the cylinder, it displaces the liquid refrigerant, causing the pressure to drop as the overall density of the refrigerant in the cylinder decreases.
