Your videos are the most simplified and well explained. Keep posting such. It has been a great practical knowledge booster for many of the youngsters like us😊👍🏻
thank you for making very informative video -as you mentioned at the end waiting video regarding other problems facing on refrigeration ,keep doing very good work lecky
Kindly it would be nice to elaborate on superheat thing. First of all if the system was running fine before this problem happened and there was no work done on the TXV of veg room . So why to solve the problem we have to open the TXV more . As we know it has been set by factory before it was fitted as per requirement of the system. That clearly says that TXV should automatically open more as per the operational requirement. That means opening pressure due to the bulb sensing is not sufficient to maintain the superheat. Though the action solved the problem but I feel if TXV is malfunctioning then it needs to be changed so that it maintains the temperature in the previous setting of the TXV.
Good job sir jake kaya pala nag ice build up yung evaporator ng chiller dahil d wastong pagset yung TXV..lage po ako nanonood sa vlog nyu sir.sana palarin gaya nyu po.
Thankyou sir very informative .. seaferer din ako passenger vessel mag isa lang din po ako na reefer dito ... upload ka din sir sa trouble ng chiller compressor
its up to you to research,. they teach you what you need to know the rest is up to you. your going to have to learn how to learn. you will have to start thinking for your self now, no one can teach you everything, no one!
Salamat Po!Keep in mind my friend that as ship's ETO to deal with refrigerators and A/C IS NOT YOUR OBLIGATION OR JOB!!!Where is your engineers?Scratching the ases in ECR perhaps?Let them do their job where a refrigeration systems is one of their duties!
It depends on the situation on board. Sometimes you have engineers who are so helpless... Better to do it by yourself to be sure that job is done and nobody gives you extra problems when doing some shit there. Sometimes you knowleges much better than your team in this area, and if people on board are good- better to help them) But if there are lazy stupid motherfuckers- of course send them to do their job))😅
As always excellent and informative video keep them coming. This is a common problem I’ve encountered this many times but the Chief just had me use hot water to break up the ice 🧊
Dear Jake, Icing on evaporator ,so you reduced the super heat by turning it into counter clock wise. Actually here, superheat was "increased". I believe it's done after turning the adjustment screw to "clock wise ."
Hi,, thanks for the vedio which is very usefull.. Lecky,, I have a same trouble which is Ice deposit on expansion valve. I have cleaned inside filter and run the system. But trouble is remaining still. Unfortunately , I dont have a spare one onboard ...😒
Our Blaster Freezer room (-40C) frequently have icing on the floor (we have proper door with gasket and curtain strips but hot air from outside or products when we push the hot product into the room to freeze them). Our floor has changed to use PU to reduce icing and anti-slip yet still have this issue... do you have any suggestions?
Thank you for this video. I still have a question, how do you know the level of the refrigerent is okay? And how do you assess the evaporators on your meat and fish room are still good?
For the level, check your pressures, and on the sight glass you will see the level. For the evap of meat room and fish room, no ice to thaw on the grill and the temperature is in range.
So is the same compressor running all 3 rooms? I was curious on refrigerant level as well but did not see any gauge readings. Nice video. I would like to see a little more testing before your determination. Thank you. Im about to get certified but lack experience because of covid schooling turned to online.
@@SCAMATICS777 Its the same as a multi split system AC. no difference, dont confuse yourself with labels, look at what they are, just a pump cycle with switches and relays, oh and mini switches and relays (PCB's). easy as pie, a trained money could do this work. im living proof.
You can see the refrigerant level on the sightglass paced on the condenser unit wich should be at middle the liquid level. Furthermore the temperature from fish and meat room are both in range -18 °C, also you can see the refrigerante gauge from low pressure the indication should be about 1 bar or higher with one of the chamber are working, i hope this make sense and can help you.
Good day sir lecky may tanung po ako tungkol sa MGPS nmin dito, kasi may voltahi nman papuntang cells nya ang problima walang current reading sa or no current indicaes at ammeter. Thank you sir lecky isa narin po akng electrician sa barko dito sa cebu interisland lang muna sir.
Hi Elect, thank you for the video, just curious if the vegetable room have evaporator pressure regulator since the piping is interconnected with meat and fish freezer? Means both suction pressure are the same. Provision compressors on this video is Bitzer / Sabroe open type.
I liked the video.,yes there is a great responsibility to keep the system going,out at sea.Water is the superheat U maintain on this cooler? In future show us the superheat setting
Hello leckay goo day! may tanong lang po ako sa reefer provision namin ang MEAT ROOM hindi mag auto start...pero mag auto stop naman? Pls. share your a good idea..
Gmg sir saw ur vidio on no spare of txv.how to make. And troubleshooting for icing on evaporator.thanx Best regards Imran kazi 2nd engineer Teekay tanker ship mgmt.
Yeah low pressure. Because the TEV doesn't let enough refrigerant through the pressure will drop and the refrigerant will start to evaporate at low temperatures.
Hi! Lecky Jake good day to you. Elect I have a question maybe you can help me. My question is, what is the common caused or the problem of the Cylinder head and the line in Marine Refrigeration Icing?
Due to high superheat this prblm occured. So u lower the superheat prblm solved. I see u anticlockwise valve turn that mean u reduce the flow of refrigent? Normally we seen all valve anticlockwise mean open the valve.
Okay I love you videos but you do know you should mention to people if you take off a solenoid coil when it's energized that you going to end up burning up the coil
How we know we increased or decreased superheat by turning the screw.is there any marking for clock wise and anticlock wise for increased or decreased the superheat
Napaka systematic mo talaga sir pag apporach sa problem. Thumbs up!
Thank you and sana meron ka din sayo na yung convinient ka sa ginagawa mo. Safe sailing

yes, i would suggest changing out the txv screen first. They get clogged often and buildup of ice immediately upon start up is a hint to this issue.

Are u eto
Superheat is reduced by turning anticlockwise.
Thanks a lot for sharing your thoughts

Nice very informative video. Just piece of advice much better and safer to use water in defrosting expansion valve.
Thank you so much for your information
Nice video sir thanks
Excellent,,

Super heat and subcooling is hoew to tune a system, go look it up. you will need to know what they mean if your going for a jab,... i mean job.

Okay
Thanks for the video!!!
Wait for this video
Thank you for your support
@@leckyjake thanh You for this perfect video!!! Really!
I'll love to be side by side with you while you do the troubleshooting,,, I'll be asking 2 million questions 😂😂
It simply needed an off cycle defrost timer installed or replaced. Or may have been trying to run it too cold. I doubt the txv needed adjusting.
It is actually a vegetable room so no defrost for the system
@@leckyjake How do you keep 4C in there without defrost ? In a humid enviroment in a kitchen and especially on a ship at sea.
5:36 - That was one-half turn.
Super thank you sir
Very good vedio ..after watching yr vedio thing came in my mind Is let me first subscribe then go for next😂
Thank you sir
Hi thx u for the content , I got confused when u lower the super heat the ice will be melted? Isn't increasing the heat will melt the ice
Salamat sa idea master
After long time sir
Just arrived in the port today
Thank you.
What will be the problem if i get ice only on expansion valve but not on Evaporator.
how about back pressure control valve on the evaporator out let? does it function correctly? need adjustment. i guess.
I talk about you new generation eto officers to watch your videos :)
Thank you very much for your wonderful comment. Very much appreciated
Good one sir. Sir how did u adjusting the manual txv value did there is any specific adjustment value is there ah sir

Hi sir..one issue on our E/R package AC unit... When we switch on the system suction pressure going negative 😢
Some of ur solenoid valve is not going to onn bro
Could you please explain the fish room tem. Not coming more then -15 dig set tem. Is -18 dig. Meat room mainten 18dig.
Defrosting procedure using water is not an excellent way of doing it. This is the old way done by old marine engineer but you have done a good job.
Sir please make one Vidio about how to test generator alarm for the serveay require
Sir saan mo po nabili magnet tool mo 3:45
Sir. Good Day! The main reason of Icing on the system is low flow of Refrigerant in the System right?? Thank you!
I lower the superheat by reducing the spring tension of the TXV.
Yeah low pressure. Because the TEV doesn't let enough refrigerant through the pressure will drop and the refrigerant will start to evaporate at low temperatures.
Nice videos, which ships are you sailing on ?
Hi! Lecky Jake good day to you. Elect I have a question maybe you can help me. My question is, what is the common caused or the problem of the Cylinder head and the line in Marine Refrigeration Icing?
Due to high superheat this prblm occured. So u lower the superheat prblm solved. I see u anticlockwise valve turn that mean u reduce the flow of refrigent? Normally we seen all valve anticlockwise mean open the valve.

it will help in Future Cadet
Next video is all about wiring diagram and modifications
@@leckyjake yes sir... Thank you... We are waiting for the next video
Sir good day , what pressure of refregirant for low and high pressure can you say that your refrigerant is enough ??thankyou
Okay I love you videos but you do know you should mention to people if you take off a solenoid coil when it's energized that you going to end up burning up the coil
I m on board as a trainee, keep waits ur video on board too
Videos will be uploaded every weekend.
Thanks for this video sir more power to you,anyway sir where you can bought your tool permanent magnet it is so nice?

How we know we increased or decreased superheat by turning the screw.is there any marking for clock wise and anticlock wise for increased or decreased the superheat
Very good job 👍
what is the suction pressure and discharge
