Refrigerants must not be vented into the atmosphere because they are harmful to the environment. When released, they contribute to ozone depletion and global warming. Proper disposal or recycling of refrigerants is necessary to prevent adverse effects on the environment.
Refrigerant pressure decreases in a refrigerant cylinder while charging with vapor because vapor has a lower density compared to liquid refrigerant. As vapor is introduced into the cylinder, it displaces the liquid refrigerant, causing the pressure to drop as the overall density of the refrigerant in the cylinder decreases.
The refrigerant in the suction line needs to be slightly warmer than the saturation temperature to prevent any liquid refrigerant from returning to the compressor, which could damage it. This temperature difference ensures that only vapor refrigerant enters the compressor for proper and efficient operation.
Restricting liquid refrigerant when charging a refrigeration system means controlling the flow of refrigerant to ensure only vapor enters the system. This is important because introducing liquid refrigerant can lead to compressor damage or poor system performance. The proper method is to add refrigerant in vapor form to prevent liquid slugging and ensure efficient operation.
An overcharge of refrigerant in the system would typically result in less subcooling in the condenser. This is because the excess refrigerant can lead to higher pressures in the system, causing the refrigerant to be more volatile and reducing the amount of subcooling that occurs in the condenser.
The discharge line is hotter than the condensing refrigerant because it is where the high-pressure, high-temperature refrigerant vapor exits the compressor after being compressed. The condensing refrigerant, on the other hand, is in the process of releasing heat to the surrounding environment in the condenser, leading to a lower temperature.

In the battery is located in the cabin or in the trunk it must be vented. If it is located under the hood is does not have to be vented.
All devices used for refrigerant recovery must be certified by the EPA. If the device was manufactured before November, 1993, It must be capable of recovering 80% of the refrigerant in the appliance. If the device was manufactured after this date, it must be capable of recovering 90% of the refrigerant.
You need to be certified to purge the system. Taking the compressor off is simple but you have to remove the refrigerant first. WA can't tell you to do illegal things so I can't tell you to disconnect the lines after you have vented the refrigerant to atmosphere. I can tell you to be sure to wear safety glasses when you do it because it can frostbite your eyeballs.
Refrigerant contaminated with air won't function properly.
Ensure the charging cylinder is in an upright position to prevent liquid refrigerant from escaping. Slowly open the cylinder valve to let refrigerant flow into the system in a controlled manner. Monitor the pressure and temperature while charging to avoid overfilling the system.
because the compressor must be running to circulate the refrigerant in the system
Because air a non-condensing gas. Refrigerant is checked for all non-condensables including nitrogen, oxygen, etc. Refrigerant is also checked for contaminants during the recycling process. Once the non-condensables and contaminants are removed, the refrigerant is dried. Moisture can ruin a system as well as make it less efficient.
No, each must be vented seperately.
An A/C shop will know. The leak must be repaired before adding refrigerant.
