Back To Replace the headmaster with a full startup of the walk-in freezer with TXV adjustment. So many things wrong to list. I demonstrate how I braze, how the headmaster works and how to set up superheat.

@JuanTodoli 4 года назад

It is somewhat disappointing that professionals with a minimal assumption of logical thinking criticized Pettinato for the SH method of pipes temperature differential. So here we have a beautiful trifecta: 1) For being right. 2) For proving to be a perfect (sine qua non) method in the absence of a service port. And 3) Because a service manual from a major company confirms this in its literature. Excellent video Rick, that's a GEM for newbies coming into the trade.

Temp to temp is very accurate because it's physics! Measuring temperature at inlet yields "saturation" (75% liq/25% vapor) Saturation minus outlet on suct. line = Superheat. This is EXACTLY how Mitsubishi calculates superheat on their evaporator. Keep up great work, videos are awesome.

Great video ! That plugged up strainer was a great find wow ! after i saw that i probably would have tried to fit a drier before that Headmaster , when i see shit in a strainer , i know thier is usually more to come , possibly the compressor windings are coming apart ? you will prob be fine for a good while though. a tip for charging a finniky system , Just fill the Receiver to 80% capacity. the numbers are on the side of that receiver. the that one holds 15 lbs at 90%. so , 14 lbs is 80%. Just put 14Lbs in & your done. its the fastest way when you allready have all refrigerant removed allready. Then write total charge on the receiver in paint marker. it gives u a baseline charge for future work on that system too.

It was a water-cooled condenser at a school district that I work. It would have been on the real massive project to try to put an air-cooled condenser on the roof it was in the dishwasher area underneath the dish rack. The superheat isn't the greatest but it's better with the sub tour in there. This was a low profile low air flow model I had to have in this walk-in cooler.

It gets too cold for you guys to do this. But i had a morgue cooler that HAD to be running and the unit had a burnout. Maintenance guys replaced compressor and txv and couldn't figure out why they still had crazy head pressures. I pulled off the head master and about 1/4 of dust and junk and blown out shellac and filter dryer blew out of the lines. Needless to say i had to remove it and didn't even have a fan cycle switch. But it ran just fine over the winter but we only get to 20-25 as the low at night.

@sterlingarcher46 4 года назад

Thoroughly enjoyed the video , mate , very useful information indeed 👍 It kinda makes me wonder though , is it really worth it to have a headmaster , after witnessing how much it throws off the txv when it's bypassing the condenser , I mean , with a proper fan speed control , you can achieve a good enough regulation for the head pressure , I'm guessing it's a cost efficiency issue isn't it ? Although inverter driven fan motors seem to get cheaper so , maybe it's the future ... I work on chillers that use different voltages to regulate the fan speed , and if the parameters are correctly set up , it does work pretty well, without massive HP swings , but then again , it does require a pretty big transformer and more expensive fan motors so yeah , I guess cost innit !

@HVACRSurvival 4 года назад

It cost more in refrigerant when a headmaster is used but it's a steady pressure to the txv, and it generally doesn't wear out, it's killed as you seen in the video.

@HVACRSurvival 4 года назад

I had to recover it because the headmaster is before the receiver. (You cannot isolate it.) The TXV however is after the receiver and service valve. Your 1st question is correct, yes that is a easy way to get your values when you can't do the traditional superheat method, they recommend you do it the normal way vs the temp/temp method.

Lac-4 I believe, I showed it in the video, I'm fairly sure that is the model number, I did see in the true manual something about a check valve but I believe that is for the two peace head pressure control valves. None of the smaller ones have ever had one that I've worked on.

@HVACRSurvival 4 года назад

Yeah I would guess my level was somewhere between 70 and 80%. According to the book the tank can hold 90% of the total capacity. Don't forget, this is dependent on the location of the liquid solenoid, Generally the valve is down at the evaporator which means you can stack a column of liquid all the way down to it but some of our solenoids are located outside which reduces this capacity, Especially if you have a half inch liquid line.

Hard to believe in the early years of refrigeration they used to use an evaporator with a built in float ball and valve (on some systems) -- an evaporator that looked more like a car radiator with a cavity at the top. -- hence the "flooded evaporator". Fortunately the TX valve was invented, to make for more compact designs.

@joehead1294 3 года назад

How do you control compressor superheat without affecting evaporator superheat? And why is that condenser fan motor so oily/dirty?

@HVACRSurvival 3 года назад

Compressor superheat overrides evaporator superheat. Unfortunately this is a very short run so you're not gaining any heat between the evaporator and the condenser.in theory most manufacturers require at least 20° to 25° at the compressor.

@HVACRSurvival 3 года назад

The motor is probably oily because the seals are leaking out oil and that generally is a sign of a future failure. Keep in mind if they replaced everything I found wrong they would be building a new store. Most places want equipment to run at the minimal cost.

My bad! I remember this was a return call now. I wouldn’t have changed it a second time either. I was really surprised how dirty that screen was. Often time when I come across a failed headmaster, I leave it and opt for a fan cycling control depending on customer and their budget!

@HVACRSurvival 4 года назад

No worries👍👍I fully understand about the fan cycle control. I usually leave it up to the customer also.

What ever happened to Jim? Brazing is all about experience, just like all welding. Those joints look great.

@HVACRSurvival 4 года назад

People on RU-vid can be real ass wipes. (🤷‍♂️ 🤦‍♂️) He finally got tired of being harassed and called it quits. I learned a lot of stuff off of him, I wish he would come back. I was very inspired with all of his knowledge and his ability at his age to crank out the videos like I did. 👍👍

@ianpalmer1482 4 года назад

@@HVACRSurvival Agreed. There are a lot of techs that don't want the trade shared with the younger guys and in public. You see it on the forums all the time. Everyone wants to destroy you for getting out there and trying to help a rookie. When I was coming up through the trade years ago there were a lot of techs that were insecure and thought that if you helped a rookie you were training your replacement. It is just not true. Jim taught me a lot. You have also. Always learning.

@HVACRSurvival 4 года назад

@@ianpalmer1482 That's the way it was for me. People didn't wanna share anything either because either they didn't know themselves or they were worried they were training their replacement. In this day and age with us so understaffed that is definitely not and was not the problem then nor now. I fight the same battle trying to get into chillers and refrigerant rack systems. That is even more reason why share what I do know.

@@HVACRSurvival I'm glad you share your content. Between you and a few other good technicians on RU-vid I have learned more in the past few years than I did in class or on the job. I still take time to read information not familiar to me. Thanks.

Thanks man, I appreciate hearing that.

That was one pluggo buggo strainer right there , Dave would be proud ! I guess the YT popo got to poor ol' Jim Pettinato before he could pull out the documentation and get acquitted , or at least get a mistrial . He should sue and get his super tech badge back plus reparations !

Damn strait Sterling, I've tried getting him to reply to me with no success.

Does anyone even know of he's still kicking? Or did he hang up his gauges for the last time.

@HVACRSurvival 3 года назад

I noticed he subscribed to me in the last 90 days. Hopefully he'll come up in one of my discussions again and maybe he'll see it and come forward and let us know. From what I heard he might still be working,I believe he got treated badly online.

@HVACRSurvival 4 года назад

Short of replacing the whole system, the filter drier will need to do its job.

@joecorbin5158 4 года назад

HVACR Survival Unfortunately I have seen a lot of compressor motor burnouts on large built up systems that could never be “ changed” out. Maybe it’s wrong to do but we never have reused refrigerant that had a hint of being dirty. I understand that customers don’t like to spend money on problems but I have discovered if a system is cleaned up properly the first time an electrical burn occurs things work out for the best. Just my two cents. Every valve I have ever changed after a burn has had a filter/screen plugged beyond repair.

@HVACRSurvival 4 года назад

The refrigerant was replaced when another tech made a leak repair a couple weeks earlier. This equipment has been used and abused prior to us starting to do work for this chain. The equipment reminds me of polishing a turd, it's always gonna be a turd no matter how much you make it shine.

I'm Sorry, you can always hit the forward or backwards button on your keyboard to skip 5-15 sec forwards or backwards. If your on your phone double tap forward or backwards will do the same thing.
