- How much should be the suction pressure of a Fridge system??
Can you trouble shoot basis the suction pressure ?
How to understand the Fridge system gauges??
Why are the Freon gauges special and not normal like other pressure gauges??
This Video deals with the topic of #Refrigeration on board Ships at basic understanding level. It discusses the common misconceptions and gaps in understanding which pose a challenge to successful trouble shooting.

After sailing for almost 11 months , The concept of maintaining the room temperature by using gauges got cleared today..Thank u so much for this video Sir...Kindly upload such more videos frequently as it can help people who are appearing for thier exams like me...Thank u so much once again
Thanks. Wish we all had more time..
Well done Ramesh. PT chart has be explained little bit more. Show PT chart slightly bigger so that all can see what exactly you are explaining. Purpose of Thermostatic expansion valve may please be include in next video. Importance of superheat also may be explained
Regards.
Sure I will
thankyu sir , i am third engineer but today i get to know exactly this compound gauge.....sir please make more videos .....its very helpfull
:-). Mostly very few ships have it . They get replaced by Normal gauges unfortunately
I look forward to your channel every time our ship comes to port to see new videos
That is very encouraging.Thanks.I will try to post more. Pls share within your groups to keep me motivated :-)
Hats off to such a crystal clear explanations !! Thats too in much simpler way. Thanks again and keep sharing sir
Hello from Latvia! Finally very clear to me what to make of all the markings on those gauges thanks to your explanation! Sometimes suction gauge is not just 2in1 but 3! Also having oil pressure indication together with freon pressure and temperatures. Would also appreciate detailed video about oil in AC compressors and oil separator fitted in the line.
Thank you sir🙏🙏🙏🙏🙏
Awesome sir. The way how you teach is so very easy to understand. Thanks a lot
👍 very informative...Thank you very much...Look forward to see your upcoming videos...
Thanks for watching!
Amazing Sir....your selection of contents are unique and rare to find.....hopefully if they given a same gauge in fresh water generator, would have interesting to watch steam at 50 deg.....
Thank a lot sir. You cleared my basics in such a simple way.
Glad to hear that
always get new informations, even if watch your same video again 🙏
Sir loved the way you explained everything.Please make a video on questions answers for class 4
This is called experience ..thank u sir
Sir your way of teaching is really awesome....👍I never thought in this way.
Waiting for your next video on refrigeration .
Thanks
Lovely videos sir. I can see all of these helping me out in my exams ahead. Appreciate the efforts and will share the same with colleagues.
instablaster
basic doubts are very well cleared
good one sir, now i have understood about the compound gauge
Nice explanation sir.
Thank you very much ⚡🙌
Thank you for your explanation sir, easy to understand.
Please add videos regularly sir, My humble request sir
Sir u said in d last will discuss abt what is the reason for high suction pressure like 2 or 3 bar in coming video... waiting for tht informative video sir
Oh...Got diverted to other topics.ANyway leaky valves are the main cause
Explained clearly.thank you sir.
Chief your teaching is excellent. Waiting for more troubleshooting video's
Thank you, I will
Thank you sir for your nice explanation.
Thankyou so much sir. I was searching for such video for a long time. But sir how can we make use of this concept during air purging?
excellent explanation ...big thanks sir...
Very good lesson. Thank you sir
Thank you sir for very informative video❤
Suction pressure is getting to 2 or 3 bar would be probably when the meat room is not cooled for a long time and the temp is +10 may be. Then in that condition initially the pressure will be 3 bar and latter as cooling goes on after some time it will come down to rated pressure 0.8 to 1 bar.
Just one possibility I think.
Explained very nicely
Highly informative
Thanks chief.
Thank you sir ❤️
Nice explanation Sir.
Sir your videos are very informative and helpful. Please make a video on INDICATOR CARDS next.
Thank yo
Thanks for your suggestion.There are too many materials on this topic. I generally want to pick up topics where there is not much explanation available for easy understanding
best explanation
Very nice sir, have a doubt sir regarding internal and external equalising line. It would be big help if u can share something on this topic as well.
Sir you are awesome..
Excellent explanation Ramesh
Glad you liked it
TQ sir
thanku for clearing my doubt sir
Always welcome
good explanation
thanks sir.
Thank you sir
Thanks alot sir
Thank-you so much sir
So nice of you
Amazing
Sir where will get more vedios like this...... I mean any other channel or any paid course
Very nicely explained
Thank u sooo much sir. Waiting for future videos
Thanks
Good Day bda sahab , just watching your video ,,,, Sir please don't mind but if possible kindly , upload little quickly.Thanks.
Thanks for your support..Surely I want to, with whatever available time I get..
Sir u were talking abt tht forthcoming video which is about change in suction pressure .When tht video will come ?
OK. will keep it in mind for future..Did I tell??
Sir,as the Ambient temperature and the temp of sea water used as a cooling media in condensor also affect the suction and discharge pressure of the compressor .How the compressor discharge pressure is maintained (regulated) so that the refrigerant in condensor will condensed at varying Ambient condition.
Yes you are right, The sea water temp will definitely affect the discharge pressure. It may affect the temp of freon liquid , but the TEV can control the suction pressure.Discharge pressure cannot be really controlled.It may go up if sea water temp goes up or condenser is choked or there is Air in the system. You need to control it with maintenance.Otherwise it will trip on HP.The fridge is designed to work within the anticipated sea water temp Range ..which a ship will usually come across..Hope it clarifies your doubt
@@rmetcvideos thank you sir for clearing my doubt.
@@rmetcvideos I had the same doubt sir. Thanks Mr. Avinash for making it easy and thankyou so much sir for the efforts.
Sir on my ship on suction side there was a differential pressure gauge which also shows the lube oil pressure ? Can you explain how to read that
The total pressure or actual Pressure you see in that gauge is a SUM of the Crankcase pressure and actual LO Pressure. THe Difference is the actual LO Pressure.
@@rmetcvideos sir so how the crankcase pressure will be known? So that i can subtract it from the total.
Sir... what about discharge pr. gauge?
same.. nothing changes.. only the relevant range is displayed
Share your social sites where we can connect with you sir
Unfortunately engineers now a days, never go beyond pulling out pistons, which any good fitter can do a better job at
Thank you so much sir
