WALK IN COOLER ICED UP 

Ashton not a stupid question at all simply put a headmaster or head pressure regulating valve backs up the refrigerant in the condenser to raise the head pressure in the system on really cold days when there is not enough heat in the ambient air at the condenser. The reason we do this is when its really cold outside and your condenser has that cold air going across it it lowers your condensing temperature and while most people think that is a good thing if the condensing temp goes too low it starts to affect the performance of the expansion valve and that causes the system to not operate correctly. So by flooding the condenser the head master helps to maintain a constant liquid temperature of 100 degrees going to your expansion valve. If you have time watch my new livestream that i did as I talk about the headmaster a little more ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lBpaoxAtSzw.html

@@HVACRVIDEOS Great thanks for the info! Great channel too!

I live in Canada, headmasters play a big part on very cold days, some run fan fan cycling newer run headmasters, but listen to Chris, wicked smart dude

Headmaster is make keep head pressure above minimum level for refrigerant circulation.if headpressure is too low to push refrigerant through the expasion valve and then refrigerant will not enough to make cold air.

The headmaster is in charge of all the other masters! 😂

Thanks for watching , yeah I didn't adjust the refrigerant charge unit after I defrosted the coil.

Of course you dont add more refrigerant to an iced up system. Would be funny after defrost ;)

Thanks bud!

Right on I'm glad I didn't give you bad advice! :-)

Thanks for watching and thanks for the nice words, I'm actually in Riverside Ca. Palm springs is just one of my service areas.

No problem Collin, what brand is your hood system? Feel free to send me an email to HVACRVIDEOS@GMAIL.COM if you want, I'm really curious about your hood system

I will clarify this tonight on my livestream on youtube tonight at 5:00pm pacific standard time come on over and check it out ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lBpaoxAtSzw.html

thanks bud

Rick I just added the gas to the low side while it was still pumped down, that way I didn't have to keep pumping it down I try to "work smart not hard" :-) thanks for watching bud. FYI I am probably going live on RU-vid tonight to talk about the video

@@HVACRVIDEOS I've read about checking the receiver level this way. And I've tried it with my thermal imager while it's running and you can sometimes see the level. Generally after I clear the sight glass I'll try to calculate what the total charges was and add 10 or 15% which usually can be 3/4 to 1.5 lbs on these small units. The other thing I'll do while I'm pumping down is watch my head pressure and see if it starts Rising which can be an indication of running out of room in the reciever.

Thanks brother for the love!! #nohomo!

yep they work all the way to the roof, the imanifold has better range but the fieldpiece job link probes are catching up

I have 3 other trucks running calls and I typically have an apprentice working with me. When I am making a video I am training him at the same time. But remember I only release 2 videos a week so I'm not as busy as you think.

@@HVACRVIDEOS Ahh makes sense, a little hard being a one man show and trying to juggle work while being thorough. Thanks for your videos, keeps me on my toes and gives me some new ideas. Keep it up brother, love from Australia 😂👊✌️

Thanks !

thanks for watching

Thanks bud

that moment when he gives you a heart but no answer.

No I was looking at them on amazon but just didn't hit buy yet, I bought a bunch of podcast gear instead. So once the podcast gets going than maybe I'll pick one up

I just bit the bullet and ordered a thermal imager, it's only money right???

Well it is only money but don’t break your self.... they are pricey. We are into fall and cooler temps I’ll have to give it a whirl my self. I’d love to see you make a follow up video.

Yeah I didn't go crazy I bought the flir one pro for my phone, whether it works or not I will make a video to review it.

I have the first generation of that it works and should even let you take thermal video... it should do good... can’t wait to see the video ..

Yeah as long as the fumes don't build up its fine

The entire job took about 3 hours

I prefer to use a water hose because in my opinon it goes faster and it allows me to clean the coil at the same time, thanks for watching , I am going live on youtube tonight at 5:00pm pacific standard time come on over and check it out ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lBpaoxAtSzw.html

And throws less heat into an already warm box

It takes the same amount of BTUs to thaw the ice no matter how you get them. It's just less water with a heat gun so you don't flood the drain. Something like a quartz radiant heater can focus heat on the coil.

Has anyone tried a small steam cleaner on these? The frozen coils I normally found were in air conditioner coils in furnaces when people didn't change the air filters often enough. It is easy to thaw those just by turning the system to heating. Maybe one of those steamers would both heat and clean.

Steam? Talk about btus added to the box. Makes no sense sorry. It only takes 144btus to bring 32* ice to 32* water. To create steam your using 970 additional btus on top of the 180 needed to first boil the water. I'll stick with 144btus and watch it go down the drain instead of the air.

cause if you get out of school and get a job then spend 3 hours defrosting a small evap coil you wont have a job long

is it possible that he doesn't understand what you are talking about? some might call it the headmaster charge.... Bottom line if the unit has a headmaster it requires more refrigerant than the same system without a headmaster.

I dont know what you are talking about ........ :-)

Sounds good...ill see what i can do. Already have a good topic in mind for discussion. Have a customer with a walk-in freezer "snowing" lol..... Coil does not ice up, defrost working, holds temp well. Talking with him, they remodeled a room recently and someone had put a 1" hole through the wall into the freezee box. The snowing started the next day after they sealed it. Hes going to set up a day that we can shut it down, remove everything and do a clean out. Im thinking theres just too much humidity trapped inside

I dont understand what you are saying?

why? The freon level in the reciever can change alot in such systems when door is open or closed..... I would check the level on full load and open doors though.....

Teaching people to take their time and fix it right is the best method, when you rush you make mistakes.Thanks for watching bud!
