- TW WC and using an app to ensure we don't overfill a recovery tank.
Refrigerants have different volumes and weights and we demonstrate how that plays out with recovery tanks.

thanks so much just graduated from hvac school and this going to be my first cooling season you explained at the point school couldnt explain us properly .... thanks for a great work
Great video with clear explanation and a topic that you don't hear a lot about but that is really important. Thank you.
Thanks Michael!
Ty, you are a fantastic educator!! Thanks for all you do.
Wow, thank you!
Wow 🤩 very interesting thank you
Great info. Thanks Ty.
nice explanation👏👏👏
Great video clear explanation
Thank you
ecelent video A+
Ty, where is the promised video on the long form way of calculating max weight without the app? Mentioned at the very end, but it wasn't covered in the next video.
Sorry it's been crazy lately, I have it recorded still have to edit
I think every guy sit experience once the overpressurized blow off valve popping off inside his vehicle while he’s driving down the freeway has a good training learning experience.
No need to get excited once the blow off valve is spewing out refrigerant inside your vehicle you’re safe to know that it’s doing it’s purpose relieving pressure so it will not explode just a little loud and foggy inside your vehicle slowly and calmly roll down all your windows and drive to the nearest safest place in no big hurry to pull over and relieve a little pressure out of the low side valve until the pop off valve closes up again and you’re good to go no big deal
Sounds like you just don’t care
@@MrElemonator I don’t care if I know the valve actually work and it does exactly what it’s designed to.
In the event that a mistake in overfilling has been performed you don’t freak out and get hysterical on the freeway because it blows off inside your vehicle. You say calm as if you’re Just sipping a cuppa coffee.
It’s all about expecting the unexpected being prepared for it in safely and call me candle in a emergency situation without causing harm to yourself and others around you.
There’s people when they see a paper bag or garbage can on fire 🔥. They run around looking for water or fire extinguisher or waving their hands at it or anything they could grab trying to put it out allowing it to get bigger or spreading it.
Then there’s the guy who just calmly walked over to the paper bag and steps on it. or throw the lid over the carbage can or flips upside down calmly and slowly and puts it out.
It’s all about knowing what your working with knowing the limitations understanding how it operates.
Like when I seen a car engine burst in the flames and everybody is yelling and running around like lemmings jumping off a cliff.
I just walked out of my vehicle picking up a 30 pound tank of R134 , walk over to the front hood that is still closed turn the jug upside down open up the valve and release the refrigerant into the grill through the radiator and condenser depleted of oxygen snuffing out the fire instantly that was about to engulf the entire vehicle.
The city department water workers who are in their vehicle across the street came over to me and told me. It looked like I rehearsed that situation and that I walked over so calmly as if I knew what the outcome would be.
It’s all about thinking first.
Do you always put the same kind of refrigerant into the tank, or can you mix them as long as you keep track?
One refrigerant and label it. No mixing.
That's on the EPA
When do you know to change the max temperature on the App? Over here the hottest it gets is like 110 degrees F.
In Vegas and Phoenix I used 160 for the summer.
I just purchased a new recovery tank. I hear a rattle sound like something is inside.
Can i open/remove a valve to inspect it?
I received it. Had a gas/nitrogen charge.
I vacuumed it to 340 microns.
It was stamped 6 months ago as hydrostatically tested.
Cant find anything on google, youtube or in my EPA608/609 documents to explain what that could be.
Rust flakes in a new tank???
Help, please....
There should not be anything in there. I did find a magnet inside one once but it was not rattling around.
Maybe the dip tube straw j side. Came loose? It would be plastic though.
The heads are super difficult to remove and require a special tool. I would probably just leave it.
Make a video with it for documentation because that's a cool find.
If you live in weather above 120f do you still go with 80 percent or go to 70? Thank you Mr. Ty.🌷
Great question.
So on the app by changing the temperature to 160 it automatically adjusts the volume lower.
Before the app when I did long math I went for 60%
You are fantastic Mr.Ty🌾
I was told not to fill past 80%.
I was taught :
Take the WC and multiply 0.8x ( the WC) and then add that to the TW (tare weight) as a maximum weight to fill the take too.
That would be (.08) being 80%.
Based on your calculations you may be able to have that as a max weight, but not the 80% recommended maximum fill level recommended.
Explain....
You calculations work if you where only putting water in the tank.
You have to account for the weight of the actual refrigerant.
Some refrigerants are lighter than water while others are heavier than water.
Use the HVAC school app and it will include the specific weight of the refrigerant you are recovering.
🍺🙂👍🏻
hi. great video. regarding that app.when manualy input r410a density (67.66) it will come with different total weight as if leaving default value for 410a. i was trying to adjust calculator for r32, but im not sure what i do wrong
