Liquid recovery using evacuated tank
In this video, we will look at recovering refrigerant from a system using a passive recovery method, or in other words, recovering the refrigerant without the use of a recovery machine, but only using a scale and a recovery tank. This method can easily be used on small appliances or small refrigeration systems.

HVAC Evacuation. Leak testing by vacuum..500 microns ≠ No Leak
zhlédnutí 433Před měsícem
Is a nitrogen test necessary? Is 500 microns considered leak-free? The pressure test of 500 microns serves as a reliable leak check. A constant reading on the vacuum gauge between 500 and 1,000 microns for at least seven minutes indicates a tightly sealed, leak-free, and dry system.

Why water and refrigerants boil when they do.
zhlédnutí 8KPřed 2 lety
Why water and refrigerants boil when they do.
why is the filter drier called a "drier" ? surely there would never be moisture in the refrigerant ?
Good question! This is why I'm having a webinar on the 16th. It is important to purge the hoses when you hook up gauges to a system. A lot of technicians will not have low loss fittings although the EPA recommends that everyone uses low loss fittings. When this happens moisture can be introduced to the system. And also when people do not pull a good vacuum, meaning that they are not using a micron gauge or pulling down to 500 µm. sometimes says technicians we forget proper procedures and we make mistakes. Thank you for your comment and thank you for watching!
You might even have to wait an hour, pull vacuum again, wait an hour and do it a third time if you know the system doesn't leak (the lubricants can hold a lot of refrigerant). However, if you have a leak on the system, you might be pulling air/contamination into the system. So if you KNOW you have a leak, don't pull more than one time and only down to slightly above outside air pressure. Or you'll suck air into the leak. Blow nitrogen through the system (best to disconnect the recovery machine first, just in case) and then fix the leak. In the case you are doing a repair, you'll probably want to put the refrigerant back into the system after repairs are done. Sucking air into the recovery machine, in this case, would be bad. In that case, you'd want to recycle the tank and put virgin refrigerant into the system once repairs are done. Ideally, with a leaky system, you don't let the pressure be higher outside from the system to prevent contamination. A pressurized system above outside air pressure will leak outwards only. Lower than outside air pressure will let air/moisture leak into the system. As a side note, you can put refrigerant back into the system it came out of, but regulations allow no other option but recycling. I had to do this with a unit that a reseller sold me that was no longer compatible between the condenser and air handler due to a software upgrade. They hadn't updated their catalog to reflect this. And sold the package that would not work together. This was a microcontroller software controlled system. In fact, I think they are still selling the combo. BTW, it's still working great today with the new (and correct) air handler. Best to check with the manufacturer before you buy a combo package from a reseller. 😞
Thank you! You bring up a lot of good points. Specially about the leaks and pulling air noncondensibles back into the system. As you will know, there is so much that there is to say what video says for training purposes, this is only talking about recovering the refrigerant from the system. Maybe I will make another video where I go into all of the things you might want to look for before you actually start recovering. It is always good to hear from guys out there that are experienced. Thank you for watching and thank you for your comments!
you are so good at explaining - make it so simple to learn and understand !
Thank you! Thank you for your kind words and yes, I enjoy doing this and getting the information out to guys that are getting started. Thank you for watching!
Thank U for this Video Sir.
You are very welcome! And thank you for your comments. Thank you for watching. I'm so glad you enjoyed the video.

thank you!!! And thank you for watching!
Great video. Thanks
Thank you! A refresher or reminder to keep everyone out there sharp! Thank you for watching!
This is only if it has a receiver?
Yes, this way we can push the liquid refrigerant out of the receiver and into the recovery bottle. Just a refresher, especially for the guys that are getting started out there. Thank you for watching!
Saved for the memory bank. Thanks
Ha ha! That's a good thing to do so we don't forget things.!
Thanks for the lesson. It would be nice if it was a little shorter. To explain what deci, kilo, mega is, for the average person when you go into that type of detail their eyes glaze over. Maybe start by showing how its done, in under 3 min, then go into details that some people may be interested in doing.
Thank you for your suggestions! This gives me an idea as to what other videos I could make. Some my videos are long because I enjoy teaching and I get carried away. Some of these videos are things that are not even taught in an HVAC classroom so I just get carried away. But thank you for your suggestion and I will see what I can do about that and thank you for watching!
great video. very informative but i do have a question. why do you have the suction line coming out of the condenser?
In this video, what you are calling the condenser, I want it to be the condensing unit. Going into the condensing unit you have the liquid line and you have the suction line. If you look at any residential or commercial unit, you will see that where the compressor is it will have both the suction and the liquid line attached to it. And that is where we attach the hoses. That is the liquid line hose and suction line hose. In other words.the blue hose and the red hose. I hope this answers your question. Thank you for watching and thank you for sending the question in!
Thank you!
I'm glad you like the video! Thank you for watching and I hope this information helps!

Hey Julio do you know about the HVAC subreddit that is on Reddit? If not it is a huge hvac community loaded with entry level techs who could really use your help. If you do know about it then I would encourage you to ask one of the moderators if you could post your stuff on there like this upcoming event. It might help steer traffic back to this channel.
Thank you so much! I had never heard of it, but I am going to look it up and see if there are other people I can help on there! Thank you for letting me know!
@@AirConAcademy I posted some of my stuff on there for a little bit and it had made some impact with a few of them and they were appreciative but I was never committed to consistent posting.
@@CaptCrewSock I have not been as consistent as I should be! But I'm trying to work on it. I have a friend of mine that keeps pushing me to do more of this. Again, thank you so much!
@@CaptCrewSock Would you be willing to repost my post on Reddit? that would help a lot. If not, no worries.
If the unloaders stop working can it cause a system to go off on high head pressure?
No, it should not cost it to go out on high head. It will just make the compressor work at its maximum capacity, which is it's original design. if you're having a system that is going out on high head, check your condenser and make sure it is clean he might even want to use a flashlight to look in between the fins, make sure that someone has not replaced the condenser fan motor with a slower, running fan, make sure that the condenser fan is rotating and the proper direction for the fan blade, make sure he has not been overcharged or that there's a restriction. I hope this helps. And thank you for watching!
Good advice. Thank you sir!!

Sir please make a video on inverter AC temperature protection and what all protection is there in it!
Thank you for your suggestion. I am trying to make time to make more videos. I will see what I can do. And thank you for watching!
If we turn on the vacuum machine for 1 minute, the moisture present inside the chamber of the compressor will be removed.
Some of the moisture will be removed. But you really need a micron gauge to make sure that you have removed all of the moisture. It is recommended that you pull a vacuum down to 500 µm. it is difficult to say yes that will be long enough because no one really knows how much moisture has gone into the compressor. long before micron gages were invented we would always pull a vacuum for a minimum of 45 minutes. But like I said, it is best to use a micron gauge. Thank you for watching! And I hope this helps!
So its "purpose" is to assist in pump downs?
Hi sir my name is abhiraj from india Few days ago a Panasonic ac got installed in my home when technician come i asked him for vaccum he say ok but after installation i asked him you do vaccum my unit he say ya i do but without vaccum pump with a thumb on copper pipe i don't know anything about it so i say ok but after they go i serched it on CZcams and Google then i went to know it is called self vaccum 90 percent of indian technician do self vaccum. Vaccuming your system is crucial step it remove all the air particle. But a saw a video on CZcams he is saying that if there is low humidity and high temperature then you can do self vaccum in my case humidity is low. I don't know wheather it is right or wrong. You have a great knowledge of all the stuff so i want to know your thoughts on this. Please guide me what should I do
Nice to have you back Sir.looking forward to your videos
Thank you I hope to get more things going here!!! thank you for watching!!!!
welcome, back I have been waiting for your amazing videos!
Thank you so much for your kind words! I have just been so busy teaching that it's difficult to do everything I want to do. Thank you for watching!
Sir please make a video inverter technology
Thank you for your suggestion! I have been very busy, but I do write the suggestions down and I hope to make a video on this soon. And any other suggestions please let me know. Thank you for watching!
Sir please make video all inverter air conditioner troubleshooting and fault finding for example less refrigerant symptom and all sensor working of incerter air conditioner 😊please please please
Thank you so much sir. Pls is there any difference between refrigerator compressor and air conditioning compressor?
Remember one thing. Refrigerators or refrigeration systems will typically use a different type of refrigerant than air conditioning systems. Because of that they will use different oils, sometimes, so you need to make sure that you order or you get the correct compressor for that application. so I guess you could say that there is, or that there are some differences in them. I hope this answers you question. And thank you for watching!
Does the Alternating relay carry the load for the compressors?
No, the alternating relay would be controlling the controls. And then you would energize one contactor and then later the other contactor so you can switch back-and-forth for the primary compressor. But that is a good question! I can see why some people would wonder that. I hope this answers your question and thank you for watching!
Should i change the txv when get a bad comprresor
First question that you need to ask is what made his compressor fail? If it failed because of acid in the system, then there is no need. It failed because of a leak that has caused the compressor to overheat then there is no need. if it failed a floodback, you need to find out why you had floodback. Is it that the TXV has failed or is that someone adjusted it. Unfortunately, if it is one of these, you will not know until after you replaced the compressor. One of the things in class is when you replace a compressor you must find the reason for the failure! There is no yes or no answer to your question. This is about the best I can do. Good luck and thank you for watching!
so how exactly do you write backwards with no effort?
Riding backwards is something that I have been able to do for a long time. But sometimes I just flip the video around. That is my trade secret! Don't be telling everybody! Lol ha ha ha. Thank you for watching!
Thank you sir ! Great explanation.
I am glad you enjoyed the video. And I'm glad he liked the explanation. I just want to make it easy for you guys to understand things and become better technicians out there. Thank you for watching!
Thank you! This is a huge help with my HVAC class in my local community college.
I am so glad that I could help! I use these videos in my classes sometimes for the students. that's why I make the videos so I can help more people. Thank you for watching!
Very well put together. Thank you Sir
Thank you! I'm glad you like the video, and thank you for watching!
Is it possible for unloaders to energize with a less than full charge? Basically back n forth clicking from the unloaders. I’ve noticed my head pressure (404a) heads to 330 then I’m guessing an unloader energizes and then head pressure decreases. Happens every other minute
First, you would have to figure out how the unit is loading and unloading? I mean what is bringing the unloader on and off? Are they doing it by pressure or by temperature sensors? That means you would look at the wiring diagram to see how their energizing and energizing the unloader. If you believe the unit is low on refrigerant in order to charge it, it must be fully loaded to the correct charge. I hope this helps and I'm sorry I know it is not a direct answer, but I don't know what is going on or how things are wired so it's a little difficult to give you a definite answer. Thank you for watching!
I think I figured it out with help from the video of course. It was overcharged by 1 pound and I think the unloader valve was bleeding off the excess while keeping the compressor running. If I have that right? Charged to the correct amount and it didn’t go off again. Ran correctly
@@anthony123G very good! I'm glad you got it running correctly! Good job!

so, if the Compressor speed slows down, it will just make the AC Cools less, and not something dangerous, because the expansion valve is the one adjusting the point where the refrigerant is superheated? so we could attach the Compressor to any energy source? because I'm thinking if we could make a infra-subwoofer doubles as a compressor to cool the amplifier making the amplifier still *cold while quiet* **bass**

On these VRF's sometimes they will adjust the speed of the compressor and the fan at the same time. if you are using a TXV the TXV will make sure that you do not flood the compressor. By slowing the compressor down you're such impress will increase and do less cooling. I hope this helps! Thank you for watching!

@@AirConAcademy Yes, I still have the tabs up in the browser to continue my education. One thing I want to do is to put some gauges on the compressor outside and leave there so I can just walk out and do a quick glance to check for any leakage. What are you thoughts on that?
@@pstreicher I will be honest with you. I try that a long, long time ago and after a few months, my gauges broke because of all of the constant movement. So I don't think I would try that. I suppose if you get a set of digital gauges? Or those digital probes so you can hook on and read them from an app from your phone that might work, but you're talking about more expensive! Keep this in mind. If you keep your vents open, you don't have any leaks, and your filters are kept clean. You should never have to hook up gauges to your system. I have lived in my house for 16 years and only hooked up gauges once and that was shortly after I moved in.
@@AirConAcademy Thank you for the reply. I had thought about the longevity of the gauges being hooked up and the cost, which is not a bother to me. Yes, with everything digital today that was what I was thinking. The ability to monitor in an app like everything else today. I use a 'SENSE' electrical monitor for my house now which shows me the cycling of the AC and the wattage the motors pull when starting. I am one of those anal type persons that like to keep tabs on everything, maybe to the point of being ridiculous to some people. I'll let you and your viewers know what if anything I install and do with this idea. Also, as far as your courses at the academy, I am a consumer, retired from telcom, working with power and electronics for over 44 years. I do not plan to go into the AC business therefore I find that taking professionals courses is way too much. I would like to see AC courses that are consumer oriented with chapters or segments whereby a person could click on to learn more, even if an extra charge was added as you go. See where I'm going with this? Maybe something to think about for the future income stream. ;)
