So you charging as a liquid, but your charging it through the low side. So you’re changing the liquid into a vapor, so technically it’s going in as a vapor?

Mr. Ty, I've watched most of your HVAC series and I have to say: I'm baffled at how this much valuable information is provided for free on the internet (you have a donation setup?). Anyways, with all the theory that I have learned I can't help but think: isn't it simpler to just measure coil temperature and suction/liquid line temperatures to obtain system subcooling/superheat? A thermal camera can be all is needed to achieve this easily. By the way: I've never ever used a manometer, but I've learned so much from you I feel like I'm a pro.
Thank you! I need to set one up. You can get sh with 2 thermometers. It's a little more difficult with SC but you can use approachethod in place of it. Bryan Orr has an article on that. A thermal camera has great benefits but due to emissivity of the coils it doesn't give an accurate enough temperature. Measure quick does have the ability to check a system charge without attaching gages also
Thank you Mr.Ty is possible to use super heat or subcooling for checking ductless mini split utilize with capillary tube or recover the refrigerant and charge it?another question when open the flare fittings is possible to re- use it again? Thanks.🌼🌷
Ductless mini splits have very specific charging procedures. Usually they require charge by weight. But you have to follow that specific manufactures method. Reusing a flare is risky. Reusing a flare is best done with a type of flare gasket.
Just starting watching some of your vids. For the most part I like your style and how are your explaining everything. Now I know doing vids to fit all content would take up a lot of time just watching you do every spot, connections, by step by step. With that said I am an instructor for about 5 yrs now, with 16yrs field experience and the main reason for this post is... why did you not bleed your high side and then pumped that liquid back into the system? Again I like your vids and haven't yet used one of your video's in my class room because I am a stickler for doing every step perfectly. ( no I'm not perfect just strive to be )
I will have to done check pretty sure I bled the charge bose threw the suction side then opened the high side and drained it to the suction side and lifter the hoses so any liquid would drain in. The also lifted the suction hose so any potential traped liquid would flow in. It's possible it got deleted by acadent but I remember seeing it during the edit. Editing is my biggest pain. I will look tonight when I get off work.
is it ok to have 13.5 subcooling on a 10 +- 2 Target? per manufacturer? Only slightly higher amps? Will it perform better in heatpump by having more freon? in the winder when the volume goes down due to the cold?
It will not perform any better. It could end up with more system wear and higher pressures and lower performance. In heat pump mode the system uses less refrigerant so a higher subcooling could end up flooding the systems. Stay within the manufactures specifications.
Hey ty I’ve noticed here in Vegas when Dealing with a piston , As I’m getting the IDWB and the condenser dry bulb to try and find my target super heat it’s usually off the charts. Is it because it’s just so hot here and the humidity sucks ?? And if I can’t find the target superheat how do I know what to charge the unit up to?? I usually just charge it up until I get a good split but I know that’s not the correct way.. Thanks !!!
It means it's outside of design conditions. With that metering device and those conditions it should not be run because the superheat will be too low and can cause compressor damage. That is why the TXV is sooooooooo important in that climate. I talked to one contractor in Vegas that uses fixed offices just so the units won't last as long.
Great question. With it running 1st, we can only get it into the suction side. If I was to open the high side it would not flow because the compressor in the system has raised the pressure higher than the pressure in the tank. Now that I can only put it in the low side, and it has to be liquid (400 series) I throttle it in, very small amounts at a time That give it time to flash or boil into a vapor while in the hosees, manifold, connection, and large volume suction line. By the time it gets to the compressor it is a vapor. If I was to open the valve for to long, I would get liquid to the compressor. If I was to put it in the suction side with the system off, I would damage the compressor.
@@love2hvac Hi, I have a quick question. I'm wondering how that liquid 410a refrigerant turn into vapor through hosees, manifold, connection, and large volume suction line. what is reason beyond it? I get that large volume suction line means low pressure and it drops boiling point lower but I still don't get what exact reason makes this liquid refrigerant become vapor through this process. and I have another question that how come 410a refrigerant can keep both liquid and vapor state in tank with ambient (atmosphere) temperature although it has extremly low boiling point. shouldn't it be only vapor in tank since our atmosphere temperature can't be -55.3°F mostly. I would appreciate it if you could answer my quesitons, thank you
Have you had the yellow scale lose Bluetooth contact with the meter in the middle of your charge ! Sometimes it reconnects improperly keeps track of the charge that you lost track of well it lost Bluetooth connection. And then other times it does not reconnect for track to charge that went into your system, not critically important on a large split system But on a small reach in box or refrigerator or prep table we’re only talking about ounces do you have to completely remove your charge and start all over again. That’s why I have stopped using that yellow scale and so have many other technicians and You Tube HVAC content providers
Mine is not blue tooth. Its just wireless to the digital display. It was when they first came out but when it lowers off it shows where if left off even if it's weeks between use. Good to know about the blue tooth.
@@love2hvac yes wireless but I believe they use the Bluetooth frequency range It was OK when it re-capture signal and has held on and recorded the weight But after the third time of losing the weight in the middle of charging that’s when I mothballed it and only keep it as a secondary back up scale in emergency. With the NAVAC scale I have not had that problem
Throttle it in. I expand this in the playlist series in great detail. Open and close the valve in very small increments, it lets a little burst of liquid into the hose and allows that liquid to expand and boil into a vapor before it reaches the compressor. The liquid line is higher pressure than the tank. Physics will not allow the pressure of the tank to overcome the high pressure of the system to charge. If it was not for the check valve in the tank liquid from the unit would leave and enter the tank because of the pressure difference.
@@love2hvac is that just for r410a or other refigerants as well? im a facilities manager and just recently started doing alot of hvac work. im going to check out all your videos and that playlist thanks brotha, need to learn as much as i can if you have any recommendations let me know.

Don't get any better than that!
Just waking up coffee in the morning and your gaining knowledge.
What a way to start the day.
Thanks mr ty .
You doing cool video's man! Keep it up! I watched your video's from class, they are awesome!
Love this kind of content. Excellent explanation. Keep em coming. Thanks form London England
It’s rally nice to see our teacher in the field 👍👍
Great video Ty! Love the content please keep them coming when possible.
Nice job, I’m a ME and I do some HVAC jobs on the side. I like you’re videos.
Such great professional process. Thx for sharing.
You rock Ty, a natural.
Disclaimer: this video is intended for trained professionals, carrying the appropriate certifications. Lol. Great stuff. Thank you Ty.
Great video

Thank you
Toubleshooting/changing components, cutting/brazing pipe and recovery, evacuate and recharging units. That's how you make money 💰 in HVAC!
So you charging as a liquid, but your charging it through the low side. So you’re changing the liquid into a vapor, so technically it’s going in as a vapor?

I need to set one up.
You can get sh with 2 thermometers. It's a little more difficult with SC but you can use approachethod in place of it. Bryan Orr has an article on that.
A thermal camera has great benefits but due to emissivity of the coils it doesn't give an accurate enough temperature.
Measure quick does have the ability to check a system charge without attaching gages also

Well done but did you connect the red hose to high side? if yes I think you didn't purge the red hose.Thank you for this excellent content.
I don’t see the link to the charts you used.

Ok so would you recommend doing when charging a unit with a piston and the target superheat is outside of designed conditions? Thanks for the reply!!
@@love2hvac what*
Charge to 5 superheat. Never less
My head is spinning 😮
why you pour liquid in the suction (Low) side ??
Won't it damage the compressor because liquid is not compressible!!!
great video by the way
thanks
Great question.
With it running
1st, we can only get it into the suction side. If I was to open the high side it would not flow because the compressor in the system has raised the pressure higher than the pressure in the tank.

Not a nuclear reactor here, just a lot of numbers on that gauge.
im confused sir, if your adding it as a liquid why are you charging it into the gas line instead of the liquid high line?
Throttle it in. I expand this in the playlist series in great detail.
