Condenser Discharge Air Temperature

Great training video. Love how you’re using the text to callouts to convey the major points. Well done sir.

hay teacher.i like your channel but i suffer to understand your english so fast,am from algeria.thanx for the information and good luck

You definitely run into some really bizarre repairs from time to time. I once found a system where the condenser fan blade had been reinstalled upside down, with the hub and set screw facing the motor. That made it super difficult to get a wrench on the set screw, so I can't imagine how this guy never realized that he put it on backwards. Pretty scary when you think about how much extra effort he put in, to do it wrong.

I appreciate how you knowingly put this video out there, knowing full well how many super techs out there are gonna dive on this

Even when I'm not working when I walk by a condensing unit I will a lot of times put my hand over it out of habit.

Great video.

After cleaning the condenser coil, I test the heat coming off the condenser fan. Outside was 99° and the air coming off the top was 122°. The amp draw for both the condenser fan and compressor were too low. This was a 1993 Lennox Sit System. I suggested to the customer to replace the system.

Can I apply school online and get certified?? Very interested plus I work as a Reefer man on board a ship 🚢 pls hit me back.
Thank you

Isn't it working better if it is hotter? That would mean it is rejecting more heat. What you don't want is a condenser not rejecting much heat though admitedly newer systems that are more efficient have lower splits.

Thanks a lot for u time I really have learned a lot from u podcast and you tube videos

Great job Brian

I have seen old equipment have what I feel like is fan blade fatigue. Have seen particular older Trane splits that the fan blade lost its pitch or something, and a fan blade replacement brought the head down and bought units a little more life. Something to consider in relation to this topic.

@ :25 Not exactly pointing at the suction line....more at the liquid line

I find 8-12 on a R-410a unit and 18-22 on a R22 unit. It’s something I check on every single unit so I evaluate exactly how the unit operating. Pretty neat if you ask me.

Just when I thought I new it all...

Thank you very much for your teaching God bless, your teaching is very appreciate it,and is very instructive, thank you very much.

what is the problem with a sys. if the condensor split is lower when the pressure is higher and. the split is higher when the pressure is lower. i thought the split should be the same with ambient temperature changes ?

What drawing is behind him?

What will be the output temperature of the refrigerant which exits from the condenser?
Anyone answer for R134a refrigerant ....

pretty good video, keep it up

Great job

So....
What is the condenser discharged air temperature exiting the condenser coil u it in a typical 80degree f day?
Thnks

So the fan is meant to help the condenser reject heat? If i understand correctly, the fan pulls cool air through the sides in order to pass by the condenser coils and the air will then absorb the heat from the gas refrigerant, and pass out the top of the A/C. The refrigerant will also turn back into a liquid as the temperature drops. Am I correct? Correct me if I'm wrong please

Units. Units. Degrees with units.

Thank You

Have you ever heard of Too much airflow across the Condenser?? Someone was saying it would easily ice up the evap with too much fan even when hot outside ??

Thanks!

Question for anyone: Can having too cold of air around the condenser coils be an issue? If you could reasonably lower the temperature of the air going into the condenser coil without harming any of the other components, would that be a bad thing/would there be an issue with that? In my mind, having colder air going into the condenser coils will make it easier for the condenser coils to dump more heat per cycle, but I have no experience with HVAC. Would there be a dangerous or bad temperature to get those down to that might cause issues with the system, or is it only about temperature difference of air in vs air out?

Ist discharge the heat from inside home ?

How the hell do you actually find design condenser td? I have gone so deep into trying to find it. Total heat of rejection divided by refrigeration effect? Am I suppose to just trust these ball park numbers I’ve gotten from instructors based off seer ratings? How am I suppose to find required saturation temp which is outdoor ambient temp plus design condenser temp drop? Am I missing something?

I will crack up every time I see a tech with his psychrometers of the condenser. Stop it. Throw your hand over the top and get a quick evaluation of heat rejection and spend your time measuring consequential things.

Thanks
For you willingness to share
