What determines the pressure on the low pressure side of a refrigeration system?
the boiling point of refrigerant in a refrigeration or air conditioning system determines the pressure of the low side of the system
What is the main disadvantage of a dial scale?
they are not always accurate and they batteries have to be replaed when they die
Why do you need to recharge the refrigeration system?
usually the refrigerant you have pumped out of the system is contaminated (either liquid/air) contaminated refrigerant is less efficiant and will lead to a short system life. refrigerant is works kind of like the rain in a water cycle. The system starts at the compresser (the heart of the system) pushing refrigerant in to the condenser (like condensation in the clouds) condensing to a liquid and heads toward the metering device (raining) The metering devise rapidly lowers the pressure of the system into the evaporator (get the picture already?) where the refrigerant collects the heat in the refrigerated space and boils into a vapour releasing it to out side the refrigerated space. obviously there is more detail then this but thats the basic operation.
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

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 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.
Why is the line to the refrigerant cylinder purged after evacuation and before charging?
When it comes to HVAC systems, purging the line to the refrigerant cylinder is an important step in the refrigeration process. This is done after evacuation, and before charging, to ensure that the system is properly charged and functioning correctly. The purpose of purging is to remove any non-condensable gases that are present in the system. Non-condensable gases can be any gas that is not part of the refrigerant and can cause many problems in the system. These gases can cause the system to be inefficient, as they can reduce the overall efficiency and cause the system to be less effective. Non-condensable gases can also cause the system to operate at higher pressures, and this can lead to damage to the system. By purging the line to the refrigerant cylinder, any non-condensable gases are removed from the system. This allows for the system to be charged with the correct amount of refrigerant and operate at the proper pressures. Without the non-condensable gases, the system will be able to operate more efficiently and effectively. Another important reason to purge the line to the refrigerant cylinder is to ensure that the system is not overcharged. If the system is overcharged, it can cause a variety of problems. Overcharging can cause the system to become overly pressurized, and this can lead to component failure. It can also cause the system to be inefficient, as the system will be unable to cool properly. By purging any excess refrigerant prior to charging, it ensures that the system is not overcharged and will operate at the proper pressures. Overall, purging the line to the refrigerant cylinder is an important step in the refrigeration process. It ensures that the system is properly charged and functioning correctly, and it also helps to prevent overcharging and component failure.
Why must nitrogen be used only with a regulator when it is charged into a system?
Nitrogen must also have its pressure regulated before it can be used. The pressure in the cylinder is too great to be connected to a system. If a person allowed nitrogen under cylinder pressure to enter a refrigeration system, the pressure could burst some weak point in the system.

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.
Your ac only blows hot air in your Saturn sl2 1996 even though the system is fully charged and the compressor also wont go on because of low pressure switch?
How do you KNOW the system is fully charged. The 'low pressure switch' detects the level of the coolant charge. If the refrigerant charge is below a specific pressure, the switch turns off to protect the compressor. If you don't have gauges you can't determine if the refrigerant is low. There can still be enough refrigerant to "hiss" when you release the valve at the test port, but not enough to engage the pressure switch.
What does AC compressor do?
Cycles refrigerant through the system and changes the state of the refrigerant from a low pressure vapor to a high pressure vapor.
How do you know when you need freon?
The only way to know if Freon (refrigerant) is needed in an air conditioner is to use tools and gauges to measure the performance of the system. The amount of refrigerant needed is based on the design of the entire system including the size of the unit, length and size of the refrigerant lines, temperatures, and type of refrigerant. Refrigerant is not consumed. If refrigerant is needed then the system was either not charged correctly when installed or there is a leak. There could be many reasons a system is not cooling. The correct answer to the question is: A skilled service technician will determined that the system was low on refrigerant by using pressure gauges, thermometers and other tools. There not function a home owner can perform to see if refrigerant is needed.
