The amount of refrigerant vapor left in a 350 ton chiller at 0 degrees would depend on the specific system design, operating conditions, and refrigerant type used. A professional HVAC technician would need to assess the system to determine the exact amount of refrigerant vapor remaining.
See the Web Links to the left for a table of the vapor pressure of water at various temperatures.
When water is left in an open container, it can evaporate due to exposure to air. In a closed container, the water vapor will eventually reach equilibrium with the liquid water, leading to increased humidity inside the container. If the container is completely sealed, no water vapor can escape, leading to a buildup of humidity over time.
Evaporation purifies water by separating it from impurities. As water evaporates, the impurities are left behind, resulting in relatively clean water vapor. When the water vapor condenses back into liquid form, it is usually purer than the original water source.
Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. Vapor pressure is also known as equilibrium vapor pressure.
Ice melts when left on the table because the surrounding temperature is higher than the freezing point of ice (0 degrees Celsius or 32 degrees Fahrenheit), causing the ice to absorb heat energy from the environment and transition from a solid to a liquid state. This process is called melting.
In a 350-ton R-11 chiller, if all the liquid refrigerant is removed, the amount of vapor left at 0 psi would typically be minimal. The refrigerant vapor remaining would depend on the specific design and operating conditions of the chiller, but generally, the vapor pressure of R-11 at 0 psi is very low, indicating that only a small quantity of vapor would remain. Additionally, it's important to ensure that the system is properly evacuated to minimize any residual 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 EPA estimates that an average 350-ton R-11 chiller contains approximately 10 to 15 pounds of refrigerant vapor remaining at 0 psig pressure after all the liquid R-11 has been removed. This residual vapor can contribute to emissions if not properly managed during decommissioning or maintenance. Proper recovery practices are essential to minimize environmental impact and comply with regulations.
It is the percentage of a refrigerant that is either liquid or vapor. So looking at a R-22 Enthalpy chart, the first number at the base you see is 10. That 10 represents the percentage of vapor to liquid. In other words, you have 90% liquid at that point, and 10% vapor. As you move across the chart from left to right, that would be equivalent to the refrigerant boiling... as it goes through latent heat and the refrigerant boils off, the percentage of liquid to vapor gets smaller. When you get to 9... that is equal to 90% vapor/ 10% liquid. The outer lines of that dome shape would be equivalent to, on the left hand side, absolute liquid and all the way to the right hand side, absolute vapor.
Subcooling the liquid refrigerant before it leaves the condenser helps to increase the refrigeration system's efficiency by ensuring that the refrigerant is in a completely liquid state. This can improve the system's cooling capacity and reduce the risk of compressor damage due to the presence of any vapor in the system.

Refrigerant for a 1996 Buick Skylark is inserted into the low pressure AC hose. This hose is found on the left side of the engine bay.
There are 90 degrees in a left angle as there are in a right angle but the term 'left angle' is rarely used
I have a 1993 500sel. Under the hood, on the left, near the hinge is a sticker which says R134a refrigerant. You might want to check yours
Check the refrigerant pressure. There is a sensor that detects the pressure of the refrigerant. If the pressure is not high enough the compressor will never engage.
