How is the refrigerant cylinder pressure kept above the system pressure when charging with vapor from a cylinder?

The refrigerant cylinder is heated in a tub of water to no more than 90 degrees F. Electric heating blankets manufactured for this purpose may also be used.

What is the difference between azeotropic refrigerant and zeotropic refrigerant?
Azotropic will only have one boiling or condensing point for each system pressure negligible fractionation or temperature glide will occur Zeotropic will have a range of boiling and condensing points for each system pressure noticeable fractionationand glide will occur.
What is the difference between azeotropic and near-azeotropic refrigerant blends?
Azotropic will only have one boiling or condensing point for each system pressure negligible fractionation or temperature glide will occur Zeotropic will have a range of boiling and condensing points for each system pressure noticeable fractionationand glide will occur.
When a pungent odor is detected during a sealed system recovery?
It is the characteristic smell of the refrigerant.
In an open system is the vapor pressuse equal to the outside air pressure?
In an open system the vapor pressure is equal to the outside air pressure.
What is the substance that absorbs and releases heat in a cooling system?
A refrigerant is a substance that absorbs and releases heat in cooling systems.
When charging a system with vapor refrigerant from a refrigerant cylinder the cylinder will become?
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

How is the refrigerant cylinder pressure kept above the system pressure when a system is being charged with vapor from the cylinder?
Add refrigerant vapor on the low side of the system ,the compressor raises the pressure of the refrigerant on the high side of the system and lowers the pressure on the low side

What component is closed during charging to prevent the flow of refrigerant to the low-pressure side of a refrigeration system?
king valve
What is meant by restricting liquid refrigerant into a refrigeration system when charging?
Vaporizing the refrigerant
What component is closed during charging to prevent the flow of refrigerant to the low-pressure side of the refrigeration system?
The King valve is closed, starving the low pressure side, creating more vacuum while charging with a liquid
What refrigerant does a Nissan Altima 1998 take?
A 1998 Nissan Altima uses 134a refrigerant. When charging the A/C system the correct pressure should always be used. An undercharged system will not cool properly and an overcharged system can cause the lines to fail.
What is the pressure and temperaure of domestic refrigerator when charging R-134a refigerant?
Generally you charge a refrigeration system by weight, not by pressure or temperature. Say, for example, if you were adding refrigerant to a system, you might add a pound of refrigerant. You wouldn't add it until it was at a certain pressure. As for a consumer AC system in a vehicle, I couldn't tell you how much to add. Look for a reference of the amount of refrigerant in the system and start by adding half that amount maybe?
How is liquid refrigerant added to the refrigeration system when the system is out of refrigeration?
Liquid refrigerant charging of a system is normally accomplished in the liquid line. For example, when a system is out of refrigerant, liquid refrigerant can be charged into the king valve on the liquid line or receiver.
What is charging of a compressor?
It means charging the A/C system with the proper kind and amount of refrigerant + oil. Overcharging the system will damage the compressor.
