What he means is the brand new recovery tank comes with a nitrogen charge, that needs to be bled off, just open it and let it shoot out. Then, you want to pull a vacuum on your recovery tank to ensure it is free of any non-condensables from blowing the nitrogen charge.
This is the best video so far and so easy to understand. I really thank you very much for helping me after so long to understand the process even at school where I studied they didn’t explain it so easy. Please continue making this great videos 🙏🙏
Remember people these are basic videos for beginners so please don't try any of this unless you get hands-on training from some it can be very dangerous or you can destroy AC unit videos are very good for people who are in school or are learning from a professional
great explain , please could you explain high pressure refrigerant recovery and store method in chiller plant , what is the function of heat exchanger in that method?
Or get a real recovery machine Fieldpiece MR45 and do a dual-hose recovery at the same time. I don't have time to be standing around. Or close one valve and pull it all out one side. But when you are using a Robinair with a Vevor junk tank, maybe this is how it is done.
Unfortunately, we don't do that in Europe. Due to regulations introduced by mentally ill bureaucrats, the gas is being released into the atmosphere. The regulations state that in order to empty the device of refrigerant, you must have a specialized license issued by the government. To obtain a license, you must complete an expensive course and pass an exam in which, in addition to the technical aspects, you must learn several Directives, i.e. complex legal acts. The directives introduced a complicated administrative procedure requiring the preparation of protocols for each activity. After recovering the factor, it must be delivered in a specialized car to one designated foundation that accepts it, but it has to be paid dearly for it. If you make mistakes, they may take away your F-gas license and give you a large fine. The only way to avoid errors and costs associated with supplying the refrigerant for regeneration is to release the refrigerant into the atmosphere and prepare a report that the installation was leaky and the gas escaped on its own.
Hello sir I loved your videos I'm a technician teacher in tigray regional state of Ethiopia. Can I use your videos to translate language and publish in my channel?
In the liquid line, the liquid refrigerant will be there. In the vapor line, vapor refrigerant will be there. So, recovering vapor in the vapor port will be easy and quick. And if we try to recover vapor in the liquid port, it may damage the ac system and recovery machine.
@@zebralearningsenglish-pn6fl Into the recovery cylinder. There is a liquid side and a vapor side. You can just recover liquid into the vapor side of the empty recovery cylinder....
Please use refrigerant weighing scale during recovery to ensure that you dont overcharge thr cylinder above 80%. The formula to calculate the allowable maximum weight of rerigerant is; Max Wt=(0.8 × WC) + TW. -WC is water capacity and TW is weight of empty cylinder. Their values are stamped on the cylinder coller. Overcharge can cause explosion. Dont play play!
Releasing refrigerants into the atmosphere is incredibly harmful to the environment and often illegal. Responsible practices involve recovering the refrigerant. It can then be sent to facilities for reuse or safe disposal. This is a much better option than just venting it into the sky.
