Refrigerant Storage in Off System: Gas or Liquid?

In summary, the refrigerant is stored in all parts of the cooling system, including the compressor and vaporizer. When the system is switched off, the refrigerant evaporates and increases the pressure and temperature in the closed system. After a certain time, the refrigerant reaches the ambient temperature and could be in a two-phase regime or completely evaporated. The liquid phase may enter the compressor if there is a valve that is not tight, and AC mechanics advise against tilting the compressor during shifting or relocating to prevent the possibility of lubricating oil flooding the compressor chamber or entering into the condenser. This could cause further problems as it works its way through the system.

WHERE is the refrigerant stored in the refrigeration system when the system is in OFF and
in WHAT state Gas or Liquid ?

After switching off the cooling system the refrigerant evaporates, increasing the pressure in the closed system and therefore also the temperature. After a certain time the temperature of the refrigerant corresponds to the ambient temperature. Depending on the type of coolant, its state could be in the two-phase regime (at vapor pressure corresponding to the ambient temperature) or it could be entirely evaporated and the system contains only gas.

...and it just remains in the tubes.

Thanks
But where will the two phase regime stay
Within the compressor or the tubes

But once it reaches the vapor pressure, some of it becomes liquid and if so will the liquid remains in the tube ?

Sure. Where else could it go?

@ russ_watters
Why can't the liquid flow to the compressor cavity.
Why then the ac mechanics advise us not to tilt the compressor during shifting or relocating. They say it is the compressor that stores the gas during OFF.
Please expalin this part.

The refrigerant normally is stored in all parts of the cooling system (compressor, vaporizer, ...) .If the coolant is in two-phase region, part of the liquid phase could enter the compressor, if, after switching it off and turning/shifting/tilting the device, one of the valves is not tight (or even open) - this especially concerns the inlet valve, which is constructed to open, if the pressure outside of the compressor exceeds the pressure in the inside.

I think it has more to do with the possibility of the lubricating oil flooding the compressor chamber, or entering into the condenser in bulk.
If the bulk of oil is pushed along and enters the capillary tube then more problems...as it works it way through
 

1. What is the difference between storing refrigerant in gas versus liquid form?

The main difference is the state of matter. Gas is in a gaseous state, while liquid is in a liquid state. Gas takes up more volume than liquid, so it may require more storage space. However, gas is easier to handle and transport compared to liquid.

2. How do I determine the appropriate storage method for refrigerant?

The appropriate storage method for refrigerant depends on several factors such as the type of refrigerant, the amount being stored, and the storage regulations in your area. It is best to consult with a professional to determine the most suitable storage method for your specific situation.

3. Can refrigerant be stored in any type of container?

No, refrigerant should only be stored in containers that are specifically designed and approved for storing refrigerant. Using improper containers can be dangerous and may result in leaks or explosions.

4. What are the safety precautions for storing refrigerant?

Some important safety precautions for storing refrigerant include storing it in a well-ventilated area, keeping it away from heat sources, and following all storage regulations and guidelines. It is also important to label and properly seal all containers to prevent leaks.

5. How long can refrigerant be safely stored?

The length of time that refrigerant can be safely stored varies depending on the type of refrigerant and the storage conditions. In general, it is recommended to use refrigerant within one year of purchase. It is important to regularly check the expiration date and condition of stored refrigerant to ensure it is still safe to use.
