Target Super Heat Formula is ..................((WB X 3) - C - ODA) divided by 2 .........Using your numbers it would be ((68 X 3) - 80 - 95) / 2 .......((204) - 80 - 95) / 2.......(204 - 80 - 95) =29 ....29 /2 = 14.5 your Target Super Heat.......WB = wet bulb , C = Constant which is 80(never changes) , ODA = Outdoor Ambient

Thanks for the formula, that was the only thing I didn't see on vid, how to get to the,actual target superheat without an app.

Going by your TARGET SUPERHEAT formula, I set it equal to indoor wet bulb. WB = [(TSH*2) + 80 + ODA] ÷ 3 WB: indoor wet bulb temp ODA: outdoor ambient temp

Thanks man ! I currently attend HVAC school. I was afraid of enrolling because usually teachers don't cover eeeeeverything you need to know. But I knew people like YOU, Craig, Jay from word of advice tv and the cool bald guy from HVAC SCHOOL could help me fill in the gaps. Whenever I enrolled in trade school I wanted to make sure I chose a field with plenty of information available to educate myself and not rely on coworkers and teachers. You guys are the reason. I chose HVAC and not something else. Thank you for helping me pursue the goal of going back to school and pursuing a technical education. That's what I wanted 10 years ago but all my family went to college and I didn't think I was smart enough to learn something technical. So I got a bachelor's in business. I've worked on myself and now I'm confident enough to try it. Thank you for supporting my education.

I have seen people doing dry bulb differently. They checking it at the closest return to the air handler. These re two different methods. Which one is correct because both will give you totally different readings as the one from return will definitely be cooler depending on how long the ac was on for before taking the readings.

[@adamspears3819]

So your Fieldpiece is calculating the Wet Bulb Temp off of the principal of "Evaporative Cooling". An example of Evaporative Cooling is standing outside & wetting your finger, then holding your wetted finger in the air to "feel" which direction the wind is blowing from. That intense cooling sensation that you feel in your wetted finger as the wind blows over it is an effect called "Evaporative Cooling" When we get the indoor Wet Bulb Temp on the inlet of the Evap coil, we are doing the same thing, except it's not our finger, it's a wetted sock & the Web Bulb meter is calculating the temp at which the Evaporative Cooling effect is taking place. I noticed, that IF the only criteria that changes is the Wet Bulb Temp (the outside ambient temp doesn't change; the low side & high side pressures don't change)....the ONLY thing that changes is the indoor Wet Bulb Temp. I have noticed that if the indoor Wet Bulb Temp increases, my Target Superheat increases too; & vise versa if my indoor Wet Bulb Temp decreases. But remember that this is not for TXV systems. This is for piston/fixed bore metering device systems. I suspect that this may be why I get a higher Target Superheat, when I am dealing with a system that is running during a "Hot Pull-Down" -Because of the added humidity in the conditioned space. Also, don't expect an 18 to 22 deg split across the Evap Coil when the conditioned space has elevated humidity levels (i.e. during a Hot Pull-Down) because it takes Latent Heat to remove humidity, & that cannot be measured by your thermometer. These are just a couple of things that I have learned out in the field & I wanted to share them to the new techs to help them. Thanks for the awesome Vid Skid!!!

[@humanmale4610]

40 degrees would be the saturation temp, give or take, of the suction line about 6 inches away from the evap coil. The internal temp of the evap depends on where the refrigerant is in the coil....the further it goes though...the more heat gained. So, I just wanted to clarify when you say the refrigerant is boiling off inside the coil at 40 degrees, it's actually the saturation temp of the suction line measurement after it exits the coil. But, great video and thanks for showing some of these guys how to do it....Super heat and sub cool tell you everything about that system...it provides the starting points of where to investigate if it measures wrong.

You read the suction side temp on gauge and said the freon is boiling at 40deg and hitting the piston at 40deg. Isnt the temp from gauge on suction side, the temp of the freon that is leaving the piston (not going to piston) and already gone thru superheat? The temp from gauges liquid line should be the temp thats hitting the piston and the temp from low side gauge is the temp after the freon has turned to vapor and went through the evap coil? Im just asking for clarification because im trying to learn and that part confused me a little

Great Video on Superheat and Subcooling another aspect to low Superheat or high may not be adding or removing refrigerant that's most Techs go to but really Airflow is the Number One scenario that plays into the equation of Superheat and Subcooling .Restrictions ,kinks in liquid line ,blocked screen before the metering device or txv of course this is going in a lil different direction of just Superheat and Subcooling

[@danielburdette249]

Pretty cool video. Don’t forget the worst effect of low refrigerant charge, which is a lack of cooling for the compressor itself. There can be a pretty fine line between too much and too little refrigerant. “Beer can cold” gets thrown around all too often, and there are beer caves around here that indicate 29 degree box temps. Better not be beer can cold at that point!

Have you done one for Subcooling, yet? I'd love to listen and watch your take on subcooling.

Josh O Hernell All the units where I work have pistons so all I'm able to do is superheat. If I ever get a unit with a TXV, ill do a video for sure.

[@harpoon_bakery162]

if the lines going into the manifold are not "burped" (Bled) in the very beginning before releasing the vapor into the system (superheat), is it over for the whole system due to air contamination? In other words, will acid eventually eat it up and everything comes crashing down?

[@LexVance]

It really depends. When I was a newby I never bled the lines because I didn't know I had to and systems ran for years. It's good practice to do though from now on.

so, when you are doing this process, what is the set temperature in the thermostat?

[@LexVance]

I put it 5 degrees below what the temperature is in the apartment.

[@fixmytoyota6319]

Lex, can you check superheat pressure on the low side when the heat is on? It seems that the pressure needle flips 180?

[@LexVance]

Winter is hard. I remember around the psi is for units & put it a little below the pressure psi in winter. You can do superheat when its cold. I come back on hot days to do superheat. Thank you for watching Jim! www.DirtyMaintenanceNation.com
