Bro you really are the man!!! Thank you for your videos! I was trying and on the rise on learning this stuff but I was not getting the full explanation, but I am understanding way more clear now. 🙏
Tim, can you do something about the video frame size? It appears to be letter boxed in the middle of the frame when it could be expanded to fill the whole screen. Also, the superheat calculation that's always tossed around is wb x 3 - db - 80, all divided by 2. That gives targets of 19 and 13 for your examples, around 5 degrees higher than yours in both cases. What chart do you use and why are they so much different?
@@realSamAndrew charts vary per manufacturer. I'vr never heard of WB x 3- DB - 80 but it might be legit. Regarding frame size, I have to make it 1:1 so it works with IG.
The AC Service Tech Chart is different than the one Tim uses and is closer to the calculation I use, the one you reference. Best to go with the chart put out by the manufacturer of the piece of equipment you are working on. ((3*idWB)-80-odDB)/2 would give 21.5 & 15.5.
@@HVAC_Tips_Tricks_Calcsbut why is there such a variance? That means you can almost pick any number within reason and there is a chart that will say it's correct. I agree with following the mfg, but it seems physics should be more solid and not disagree so much or else it starts to sound like pixie dust and not science. BTW your calculation is wrong. The values based on the idwb x 3 formula are 19 and 13. You accidentally used 75 for oddb instead of 80.
@@realSamAndrewcorrect. I was using the wrong ODDB. I also don’t know why the various charts are so much different. I tend to stick with the AC service tech chart for rule of thumb if I can’t get the manufacturer charging chart.
Thanks Tim...good stuff again!
Great Videos Tim!

@@HVAC_Tips_Tricks_Calcs correct. I like that one also and the oem is better.
I chose this chart to make the point even clearer that wb changes SH.

Just one question though I am sure you are talking about super heat at the evaporator coil right, not at the condenser coil
Superheat is evap. Subcooling is condenser.
