The pressure in a refrigerant varies depending on the type of refrigerant, the temperature, and the specific conditions of the refrigeration system. Typically, refrigerants operate under high pressure in the condenser and lower pressure in the evaporator. For example, R-134a refrigerant can have pressures ranging from around 30 psi in the evaporator to over 200 psi in the condenser at room temperature. Proper monitoring and management of these pressures are crucial for efficient system performance and safety.
You cool it and run it through a metering devise.
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.
When refrigerant leaves a compressor, it is at high pressure and high temperature. The compressor raises the refrigerant's pressure as it compresses the gas, preparing it for the next stage of the refrigeration cycle. This high-pressure refrigerant then moves to the condenser, where it releases heat and changes state.
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.
The refrigerant cylinder pressure is typically higher than the system pressure, which allows the refrigerant to flow from the cylinder into the system. By opening the valve on the refrigerant cylinder, the higher pressure inside the cylinder forces the vapor refrigerant into the lower pressure system. This creates a flow of refrigerant into the system until the pressures equalize or until the desired amount of refrigerant has been added.
