Part 1: Refrigerated Production Room with Head Pressure Issues
ฝัง
- เผยแพร่เมื่อ 6 พ.ย. 2018
- My first time dealing with low ambient temperatures and adjusting fan cycle control switches.low ambient temperatures caused low head pressure which in turn cause my evaporator coils to freeze. Was not able to finish the call today, will return tomorrow when evaporators are fully defrosted to get proper readings and a final diagnosis

I just wanted to say thank you for all the great content on your channel man. It seems increasingly difficult to find accurate information now days. I sincerely appreciate you taking the time out of your day to create these uploads!
Derek McFadden thank you for watching bro. I appreciate the comment💪🏼💪🏼
Love the videos by the way.Real time tech,no bull.
Ogi Ivanov thank you. I appreciate the kind words.
Look how far you’ve come in the last year and some change! Awesome to see you progress and learn more. Great stuff man
Gracias amigo!!!👍
I usually set my fan psi controls to cut out at 85-90 saturated degrees and 35psi or lowest possible differential. Better constant liquid feed but will cycle the motor more with lowest differential setting. 🤘 good video
Good job babe 👍
Can't stop watch ur videos....lol nice jobs...
Thank you. I appreciate you watching.
Phew ...
I have to wonder: how did these fan settings get set wrong in the first place, and why didn't the problem appear sooner, like the same day the too-high fan settings were made?
sometimes you gotta put each fan on its own control, helps regulate it a little better
Yes. But I know Copeland likes to have 1 fan running all the time. Just depends on the unit I guess.
What temp is it set for or targeted and are the door constantly opened 👍🏻👍🏻good post
I believe this was set for 35, and it worked great all year till the cold came in. Lol
AC veteran but a rookie in refrigeration starting from scratch on your videos. Question shouldn’t your head pressures be higher like 200 psi if your ambient was 65 degrees so the issue would have been low on charge all along?
Which Digital probes you guys recommend.The wireless probes,the Smans4,or the Testos,may be Sporlan
I have the Fieldpiece probes and also the SMAN 480s. I like them both. There is nothing wrong with the testo gauges, but I prefer the Fieldpiece probes over the testo probes.
@@rookierefrigeration4357 you don't have any problem to get connect and disconnect because I just got the probes and have that problem tks 👍🖐
21.1 jigawatts refrigeration
After a year do you still recommend 225 cut in and 50 differential?
Depending on the system type and refrigerant, I may have tweaked it a bit. Trying to maintain a good Saturated Condensing Temp
@@rookierefrigeration4357 Got it
First year in hvac or working on refrigeration?
This video was from my first year in Refer

Awesome.
Most of us start in residential, and are awed by this refer world.
Great videos!
bro,,,,,, you have no air flow… evaporators clogged and even i saw dead evap fans. restore or confirm air flow before adjusting stuff. dirty side of those evap you can’t see. get the heat load back in that system. that’s your problem.
