When charging liquid refrigerant from a single valve supply cylinder, the cylinder should be placed upright. This orientation allows the liquid refrigerant to be drawn from the bottom of the cylinder, ensuring efficient charging into the system. Additionally, placing the cylinder upright helps prevent the intake of vapor, which could potentially harm the system. Always ensure proper safety measures and ventilation when handling refrigerants.
To remove liquid from an R22 cylinder, you need to first ensure the cylinder is upright and not tilted. Connect a recovery machine to the cylinder and open the liquid valve. Allow the recovery machine to pull out the liquid until only vapor remains in the cylinder.
In an open system, the vapor pressure of a substance is determined by the temperature and composition of the system, not by the outside air pressure. The outside air pressure can influence the rate of evaporation, but it does not directly impact the vapor pressure within the system.
When heat energy is removed from a liquid-vapor system in equilibrium, the temperature of the system decreases, leading to a shift in the equilibrium position. According to Le Chatelier's principle, the system will respond by favoring the exothermic process, which in this case is the condensation of vapor into liquid. As a result, more vapor will condense, increasing the amount of liquid while decreasing the vapor phase until a new equilibrium is established.
The respiratory system excretes carbon dioxide and water vapor. Carbon dioxide is eliminated by exhaling it from the lungs, while water vapor is also exhaled as a byproduct of metabolism and respiration.

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 kept above the system pressure by regulating the flow of refrigerant from the cylinder into the system. This is typically achieved using a charging hose with a metering device or valve that controls the rate of flow. By adjusting the flow rate, the pressure in the cylinder can be maintained higher than the system pressure during charging.
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.
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

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.
The observed process in the jar is related to the vapor pressure of the system because as the liquid evaporates and turns into vapor, it increases the pressure inside the jar. This is because the vapor molecules exert pressure on the walls of the container, leading to an increase in vapor pressure.
