How to charge ships air-conditioning unit
nice video ... sir... nadag dagan ang aking kaalaman sa repair...
Kaya mo yan sir, samahan natin ng dasal always para mapanatili nating smooth at safety sa work natin araw2x. 🙏
Thank u sir, I like this video and easy to undrstd, ..greeting from Indonesia
Salamat sa inputs sir. Gamit na gamit mga tuts nyo sir. Malaking tolong to sa akin kaka.akto ko lang 3AE. More vids pa sir. Salamat ulit at God bless po.
good information. thank you for making this video. looking forward to another video. keep it up
Very easy for understand,many thank ,Sir ..greeting from Uruguay 🇺🇾
arriba Uruguay ... I have over 25 years working in HVAC-R .
Thanks for sharing your knowledge and experience. Great background music :)
You have explained very well....thank you
Very nice... Need more electrical troubleshooting videos
Thank you Sir, for the practical knowledge and block diagram. Please sir try to cover control circuit diagram also. Thanks. 👍👍👍👍
Sir good day, specific control circuit system of what equipment of the ship machinery so that i will try to cover if i have time, or as long as motor control troubleshooting? . Thanks for watching and appreciate my video. Thanks a lot
Great explanation...thanks😊
Sir God bless 🙏 you tnx again
Thank you for sharing your knowledge
Thanks for the video , very well explained
Thanks sir super explanation .
Salamat Sir.. Good video easy for understand.
One asking Sir, can we Charging direct without close the high pressure v/v from compressor..?
sir leck sana magawan nyo din ng video regarding sa mga troubles na pwedeng maencounter sa Ref and AC system sa barko. paano mo majustify or malocate na ung isang part (like TXV, liquid line sol valve, thermostat) ang defective. thanks sir
Thank you for the video
Excellent description 👌....kindly share video of charging oil in Reefer System Compressors and Air con Compressors,
And also if need to overhauled the reefer Compressors how to depressurize Compressors crankcase.
Superb 👌
very good video sir
NICE SIR GODBLESS!
Excellent Sir! Thank you for uploading this video, How do we know how much refrigerant will be charged? and Why did you not put your bottles upside down to charge in liquid state?
Sir, No need to do upside down in unitor bottles , cause there is a liquid valve that have a pipe deep until buttom og the bottle and gas valve at the top on the bottle.
Nice video
very good video
nice thank you very much
Thank you so much sir
Sir good day, thank you po sa very knowledgeable na procedure sa pag charging tru liquid refrigerant, may tanong lang ako sir if open ba palagi yung valve ng cylinder tank ng refrigerant habang naka-andar yung compressor hanggang magtrigger yung low suction pres. switch. thanks in advance sir🤗
Hello! Thanks for the awesome video! How can I properly take oil samples of this kind of compressors? Thanks again!!
Sana nag explain ka kung saan ang low pressure side at high pressure side at kung saan ang liquid state at vappor state
Nice.
Nice video...........................DJ Kroz
Sir..purging refrigerant in atmosphere is prohibited by annex6. How to purge with help of recovery bottle??
tnx
Barko ,,,explain also gas charging ...when the system is running or stop .....Thanks
Sir gud day! Clarify lng sir..
Once you pump down the system or close the isolation valve the compressor stop because the low pressure triggered. After this, open the charging valve to pass the refrigerant. Normally the compressure will run but as you said, bec of the anti recycling it will delay the start for about 20 mins. To cancel the anti recycling, stop the system and switch off. Then switch on and start again.
1) Once the system start again, does the compressor run immediately due to the charging pressure?
2) Why need to stop and start repeatedly?
3) D b po tatakbo na man po ang compressor continuos basta nkaopen lng ang charging ng refrigerant?
4) kpag ngstop and start ka ng system repeatedly kelangn switch off po ba nag breaker or hindi na?
1. Run immediately.
2. Pag naka bukas ang charging valve, minsan ina abot ng low pressure pag tatakbo ang compressor,
Pwede mo rin turn off main power para ma reset ang anti recycling time. Sana maka tulong
Related sa akin to boss ah..d 2 ako qatar navy.
how about using different refrigerant, is still same way for charging, i mean from nepel before dryer?
Kahit in auto service po sir pwedi po sya gawen pag karga ng refrigerant? Thanks po for these video
so when you connect the filling hose to the cooling system, is the compressor still running or stop condition? because you know the valve after condensor already closed
great
Kindly share a video, the procedure of changing the filter drier of AC/Ref, step by step ...Many Thanks Sir
Sir, changing filter dryer, open bypass and, just close before and after dryer isolation valve. Hope this will help you
@@BarkoTv love you Sir Many thanks .
Sir function nman ng txv sir?, thank you sir...🙏
How we prevent entry of air to the system..did we use any type of recovery bottle in this system?
We can prevent air going to our system by purging refrigerant to the charging hose before opening the liquid charging valve
How to start filling the empty system after replacement of compressor and evacuation od system?
Please feel free to browse my playlist for aircon maintenance. For new compressor, need to use your vacuum pump for evacuation process to remove un condensible/air on your system
sir leck ask ko lng po, sa ganyang type ng refrigerant bottle no need na po ba itaob ang bottle to take liquid refrigerant? nasanay po ksi ako sa disposable na bottle ung maliit lng na refrigerant bottle sir. bale from that refrigerant bottle valves. mkakuha ng liquid refrigerant sa red valve and gas refrigerant naman sa blue valves without flipping the bottle sir? sana po manotice nyo sir. bagong subscriber nyo po. thanks a lot sir sa mga video tutorials nyo.
Sir pasensya sa delay na reply kasi hirap maka access ng youtube, minsan lng talaga aq maka reply,. Di na kailangan baliktatin sir, bukas ka lang ng valve kung gusto mo ng liquid or gas. Salamat sayo sir
👍🏼👍🏼
Sir what is the purpose or function of the solenoid before expansion valve?
When the desired temperature setpoint is reached, the solenoid will activates then the system will pump down it self and stop cause the low pressure switch is activated
Gd day boss. Ilang psi po ang 404a low at high.
Hi sir I have problem about ac system . When ı start the 4th stage lp be coming until 3,8 and hp 18 evap side has startıng ıce also 3rd stage not enought for cooling fan flap position %30 open from atmosphere and evap good condıtıon air flow is good out sıde temp 35. When compressor stop posıtıon condenser liquıt level is full but when ı start comp glass showing emty lıquıt. So ıce problem is less gas or not
Try first Isolate/disconnect the 4th stage, and run only 3rd stage, if the same situations , might be lack of charge. When in running condition, you must see the refrigerant level on the sight glass, minimum 1/4 level to 1/2
yung sa reefer provision po sir if mag change oil sa charging valve din e dedrain?
Yes sir
Mas maganda sa doon din e drain kasi my pressure pa cya, dahan2x lng bukas para isang bleed ng pressure at drain ng oil.
Sir ano kaya cause? Ayaw mawala ng compressor fault na check na din lahat ng wirings at okay. May possible po ba na may sira ang compressor? Or just electrical issues lang? Ayaw kasi mag start at mawala ng compressor fault.
Ty in advance sir.
Same A/C sir.
Sir, check ang alarm list tpos baybayin mo sa electrical manual or direct ka mismo sa mga pressure switches na naka indicate sa alarm. Sana makatulong
Hi sir,I have a problem of one provision coldroom tha evaporator coil is humming and habe loud noise please help what is the cause of being noisy,thankyou
Sorry for the delay reply. Please check the fan or check the evaporation its because full of ice that touches the fan. Hoping you already rectified the problem. I salute you. Thanks
How much psi should be?
No more R404A! You can use R407F
Para saan po yung antirecyling time😀?
Anti recycling time. That is the rest period of the system, or they called it the restarting period time delay. To avoid damage the system.
Not clear,,
