When charging an r12 system with freeze12 should you charge with gas or liquid?
if system is empty, u need to charge with correct amount of oil and refrigerant. the oil actually carries the refrigerant in the system if just recharging, buy the refrigerant that has oil already added, these are available at most auto stores
What is that charging a neutral object by bringing it close to a charging object?
Conduct
How can you tell when the Gioteck headset EX-02 for the PS3 is charged or when it is charging?
If charging charging, the side with the power button should light up red. When fully charged, it will light up blue.
Why is water added to storage cells of motorcycle and car?
The charging system may be over charging the battery. Over charging the battery can speed up the evaporation process. Have the electrical system tested.
What is charging by polarization?
Charging by polarization is the separation of positive and negative charge. Overall, the object being charged is still electrically neutral.
What happens to the saturation temperature of the liquid refrigerant inside a refrigerant tank during system charging?
multiple choice: A: It rises B: It falls C: It remains constant D: It rises slightly, then remains constant. The answer is B The Vapor leaving the refrigerant tank is replaced by the liquid that boils off into vapor as the vapor being charged leaves the tank. The liquid saturation temperature drops as liquid boils to vapor. Example; The frost on a propane tank when you BBQ or use alot of propane for ???.
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
When charging a system with vapor refrigerant from a 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
What is meant by restricting liquid refrigerant into a refrigeration system when charging?
Vaporizing the refrigerant
What is meant by restricting liquid refrigeration system when charging?
Vaporizing the Refrigerant
What is pressure temperature chart?
Used to Charge air conditioner - as ambient temperature increases gas pressure also increases. So when charging a/c systems, chart is referenced to make sure that proper amount of refrigerant is used
Why does refrigerant pressure decrease in a refrigerant cylinder while charging with vapor?
When vapor refrigerant is pulled out of a cylinder the vapor is reduced and the liquid boils to replace the vapor that has left the cylinder.
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.
What is the disadvantage of a dial scale?
They are more difficult to use when charging refrigerant into a system and more calculations are necessary to determine the amount of refrigerant charged.
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.
When filling a charging cylinder the refrigerant that is vented off the top of the cylinder?
Must be recovered
