- We had a unit having a high discharge temperature which stops the unit and go out of range.
here is the troubleshooting video I did in fixing this unit
• REFRIGERATED CONTAINER...
• TROUBLE WITH DAIKIN RE...
Thank you sharing the reefers stories that couldn't teach in school😊😊😊
Thank you sir for the technology of new generation,I am interested
Hi, Jake! Safety First! For everybody: from the begining do not forget to check Freon type. Sime times we do simple mistake, and later on we do double job! Best regards and good luck!
Hi mate thanks for sharing with us
Greetings from PNG
Finding leaks can be painful to find when your on board ship. A lot of times I’ve found that the nut at the base of the high pressure valve or the low pressure valve is loose and leaking refrigerant. It’s important to check that nut anytime you’ve opened the valve.
Salamat sir Lecky marami akong natutunan sa inyu i hope sunod maging isa ako sa maging Cadet Electrician nyu po at assistant po😊
The old pump and dump lol. Love the videos.
Nice stagging 😉 did you find a leak or oil?
Hi leckyjake, I always admired marine refrigeration. If I was contracted to do some work on a ship I would go just to try it out for once. I've worked on a couple of the transicold 69NT40 models and always wondered about the sight glass. There are two sight glasses on the receiver. A proper charge is around 5kg I think but the ball always remains pretty low on the visor. I see yours here went up pretty high. I assume the ball on the top visor should not float unless you are pumping down
I love you training kudos
Why was the leakage not fixed instead of recharging new Freon gas?
If he could use a pump to pull a vacuum there’s no leak. Air could have gotten into the system from someone not clearing gauges.
this guy is so good. so smart.
Thank you for your help, it's really helpful, thanks again
I encountered that trouble sir, found out that freon leaked in the condenser coil
Frontseat the discharge service valve and jump out the high pressure switch. Start unit and run
Good morning sir leckyjake.
BSEE student po ako at graduating na po. after po mag board exam nagbabalak po ako maging katulad nyo po na eto. bale naaral ko na po mga dapat ko gawin para maging eto. tanong ko lang po ano po ang mga training or tesda courses na dapat kong pasukin para po ngayon palang magkaron na ako ng knowledge sa pag troubleshoot ng ibat ibang machines na ginagamit sa barko. maraming salamat po
Refrigeration and Aircondition (RAC). Pag may budget ka. Marine refrigiration. 10k atah yun sa MERALCO😊
Goodjob sir
Very useful 👍
Thanks a lot for this video
Reefer Compressor, Bitzer Type VI. Head temperature going very high, Compressor disch temp almost 95. Checked cooling water flow, passages in head cleaned , condenser cleaned. Valve plate renewed
But still temperature is very high. Kindly suggest what else to check
@@danishmomin8102Check if the compressor has enough oil and if the discharge pressure sensor is okay
what triggers the low pressure temperature alarm? to -30°C, compressor pumpdown at -25°C 🙏🙏 Thanks sir...
Nice video
Sir ,please make video about megger testing
elek id like to ask you if you have experienced high temperature alarm then the oil seems to disappear. this on a chiller for an inert gas generator.
Thank brotha for the videos
is it allowed in your company to purge out the refrigerant nto the atmosphere..
Nobody seen in middle of the sea .
Hi, do you have any video for msb breaker under voltage trip.
Our Daikin reefer compressor is not working. In Mongolia nobody can fix it..
My guess would be a dirty condenser or a failed condenser fan
Yes, that was what I was thinking. It is very uncommon to have "air" or noncondensables in the system even when the sysntoms are similar. The refrigeration troubleshooting was not that good. I had never seen low side pressures and high side pressures unless it is a restriction. (Constructive critc here)
@@rightconditions2010 the containers run at a really low pressure using 134A. Depending on your temp conditions they can range from 5 to down below 0 psi which would be vacuum.
(more prone to air infiltration) His high side was definitely high for 134A. That's like a 65+ C / 150+ F coil. Discharge temps directly from the compressor would be way higher.
Usually a high discharge would reflect back onto the suction slightly but he was in range on the suction pressure. My first thought would be to look at the coil too but we didn't get to see it. The fan is easy to test since it cycles on and off due to pressure control
How many person as an electrician or assistant electrician on your vessel ?
Any idea where the refrigerant from the system went? Was there a leak you found and fixed?
Yeah, a leak seems highly possible, which means the problem will just return after some time.
Could perhaps also be that it got air trapped during its previous maintenance.
@@Gin-toki at least here in the Netherlands (I think all EU countries) I’ve come to understand it’s actually illegal to refill a suspected leaking system with fluorinated refrigerant as it’s extremely bad for the environment to get these gases into the atmosphere. Not sure what type of refrigerant this reefer is using though, might be plain CO2 these days for all we know.
@@mlenstra it was stated in the video that it's freon.
It was R134a a refrigerant not a Freon, if you go by bottle color (orange) it’s R404 a refrigerant not a Freon.
👍👍👍
Hi really need your help having trouble clearing a alarm cord Al 58 Compressor High Pressure Safety (HPS)
how much os your discharge pressure?
We are doing everything but unit running 4-5 hr good and again it will give high dicarge pressure may be it's TXV give advice plz?
👍👍👍✅
So there is a leak? Does this get recorded for testing when the container is offloaded?
I dont think if they are recorded it but its going to inspected well when the cargo is distuffed and the unit PTIed again and doing more leakage testing.
Sir paano po nagwowork ang accumulator sa compressor ?
Hi,i have additional question ,have mail or something similarly where can i contact You?
Sir I want job has a assistant electrician in your under
Pwede ba tgalog sir😅
