Liquid charging AC system

[Elb.ab]

Hello guys!
I have a question concerning charging AC system of a car. From what I read, we generally use the low pressure side to inject the refrigerant in the vapour gaz.
I also read that we can charge in liquid by putting the tank upside down.

Do you have any idea how liquid charge can be done?
Thank you for your time.

As you said, turn the can upside down to charge with liquid. However, you must regulate the flow by only opening the valve slowly so that liquid does not reach the compressor suction. You will damage the compressor if it does. Some refrigerants are mixtures, so you must charge with liquid to get the correct composition.

Thank you for your answer.

I'm not using a compressor ( i have just a bench test which i intend to charge at liquid at high pressure).
My second question, say if that i heat my tank ( thus increase the pressure ) I will get more vapor or the contrary?

Thank you again
