thanks sa info sir,please gawa ka ng vlog sa refeer van anu mga component at cycle nya lalo na sa mga barko
By the way thanks for the knowledge that you shared ❤️
Thnks sir napakaganda ng paliwanag no details by details malaking tulong po to para sa gaya ko na gusto matutu.
Salamat din po.
appreciate very much sir for the knowledge you shared. continue your advocacy I'm sure a lot will support you in you channel.
Thanks po God Bless
Very informative👍👏👏👏
Thanks for liking
Ang refrigeration system kailangan ng liquid receiver at suction acumulator lalo't na medyo mahaba-haba ang line set. Liquid receiver should be use for TXV, not for cappiliary tube because during the off cycle or the system satisfied, refrigerant tend to migrate back and flooded the evaporator. Alam na natin ang suction accumulator is prevent liquid refrigerant get to the compressor, liquid can not be compressed and some of the compressor blow up. Kahit AC employ accumulator for the heat pump or mini split because during the heat mode, the outdoor coil becomes indoor coil, accumulator prevents liquid from entering the compressor. Residential AC not common to have liquid receiver and accumulator, kagaya sa AC system, and employ capillary tube as metering device. Depende kong papano mo explained bakit ang iba tatawagin nila na, evaporator as heat absorber, and whenever this heat being absorbed, heat will be rejected to the heat rejector or condenser. Ang refrigerant para bang sponge na water will be absorbed and you can squeeze water outside the house. Sa mga nakikinig sa presentation mo medyo di talaga nila maintidihan pa, if possible we don't wanna use a technician words, kailangan yung tinatawag na laymans term. Sa atin salita natin mga HVAC/R. Salute to your basic AC and refrigeration presentations. Maayo diay Bisaya ka master medyo Bisaya kaayo akong Tagalog, maayong adlaw master, imong fans taga Leyte.
Salamat sa comment sir, much appreciated. And thank you very much for sharing. 👍
Bali Minsan kase dito sa factory matagal mag build up ung cooling coil. Bali sa set point ba sa condenser mag a adjust ? Pag nag i snow mabilis lumamig pero pag summer na matagal mag build.ung lamig ,😁 at concern ko Rin Po ung symbols ng HVAC device,equipment at fittings, ask ko lang po Kung Yung symbol ba ng mechanical pwde pag samahin sa piping and instrumentation diagram?
Nice tutorial.
Thank you! Cheers!
Nice
Done lods
Galing mo sir,Dami Kong natutunan,.kasalukuyan Po ako nag aaral ng Ref and air-conditioning sa tesda.I'm 53yrs old,pede pa kaya ako,kung aapplay ako sa seabase?Thanks,I have learned alot from u
Pwedi nyo pong subukan sir, maraming online application ngaun .. salamat po
New subscriber sir, salamat sa napaka informative vedio mo...tanong ko lang sir,yung pag aadjust ng superheat anong trabaho niya kunwari adjust ng counterclockwise o clockwise....
Salamat sir
Self study ko lang kase ginagawa.
Thats good sir, ganyan din ako natoto.. actually isa sana akong criminology dati..
Sir. Ano po trabaho ng sensing valve ng expansion valve at ng equalizer. Ng expansion. Valve. R404a
Ung sensing valve po natin ang nag uutos kung mag bubukas ba o mag sasara ang expansion valve po dependi po sa demand na hinihingi ng evaporator natin.. ung equalizer naman po, kung mapapansin nyo nakakabit po xa sa evaporator natin. That means po tumutulong xa sa pagpabukas sa expansion valve base po sa pressure na nasa evaporator natin, at take note din po na ang pressure sa evaporator natin ay correspond on temperature po
sir/master dun po ako nalilito sir sa ibg sabihin ng heat absorb sa evaporator..kung bakit kaylngan mgabsorb ng init..tulong din po ba sa pagtrnsform ng liguid refregrant pra maging vapor..pasensya na sir baguhan pa lng po..salamat po🙏🙏🙏
Noong nag-umpisa pa ako sa ganito na trabaho, i don't even know what is evaporator, condenser, metering device (TXV, EXV, Capilliary tube or piston type) is another language na matutunan natin kong nasa school kana or they HVAC/R lingo. Ganito ang nagyari sa refrigerant. sa residential AC, of course thermostat are cooling and that will send 24 Volts your condenser na nan doon ang compressor, at the same time you green wire on the thermostat send power to your air handler na doo ang evaporator. Now as the compressor keep compressing the refrigerant, comes out as a high temp high pressure vapor state, and that fillled it up your condenser coils. Ngayon ang fan mo sa condenser are on rejecting heat and becomes high temp, high pressure liquid and travelled to liquid line or discharge line. Refrigerant travels to the liquid filter drier followed by moisture indicator sight glass, then goes to the metering device, either TXV, Capilliary tube, piston type, and most of the time technician called it as metering device. Refrigerant will be restricted and becomes low temperature low pressure liquid, and this time the refrigetant will abosorbed heat from the condition spaces and becomes a low temperature low pressure vapor. If your system using a TXV you use a superheat, TXV are controlling the superheat, or capilliary tube, goes by the subcooled. Low temp low pressure vapor refrigerant goes back to the compressor until the system satisfied and the thermostat will end the cycle. Evporator is heat absorber, condenser is heat rejector, TXV, Capilliary tube, piston type is pressure reducer. Magandang mga katanungan mo at huwag kang mahihiya, sa atin meron mga school of refrigeration and Air Conditioning shop, and hopefully at the school will provide more equipment and qualified instructor because that is the main quality of the school can attract more students. Good luck for quest as HVAC/R= Heating Ventilation Air Conditioning/ Refrigeration technicians. Once you are on the real world, means on the jobsite by yourself, everything you've learned from the school, job training, working with company dyan sa Pinas, baka magiging magaling din na instructor.
Master pwede ba pag samahin sa Isang system Ang cold room at industrial refrigeration pero hiwalay ng area.
Ang ibig mo pong sabihin cguro sir, kung pweding may positive setpoint which is cold room at may negative setpoint which is freezer sa iisang system?pasenxa ma po medyo hnd ko na gets ang tanong po.
Sir pa help po ung freezer po Kasi na ginagawa ko sa company Namin ayaw mag lamig kinabitan ko po Ng expansion valve. 404a po. 3hp Ang comp.
Marami pong factor sir, pwedi pong compressor loss compression, under charge, may problima sa gas system. At marami pa.pong iba. Kilangan po natin ng complete details para po masmadali ko po kaung matulungan.. salamat po
Sir ung aicin ko sa car mahina lamig..sa out ng evap..wala din natulo fun sa drain sa ibaba ..pero dun sa line ng tube sa comp..makakas ang lamig dun -dun xa malakis pumawis at magtulo ng tubig..parang d xa gaano makabuga sa evap...ano kaya prob.isa pa ung fan ay sa radiator 2 nakakabit...iniicip ko lagyan ng manipis na fan sa harap ng condenser...peter qc.manila
Nissan sentra car ko..
Good day po sir, base po sa experience ko,, Under charge or need cleaning sa evaporator po.. salamat
Master sana mapansin nyo. After compressor High pressure high temperature vapor refrigerant flow into inlet of condenser then the condenser is to remove the laten heat wil be come a liquid, so pag lumabas na po yung refrigerant sa outlet ng condenser ang pressure po ang lalabas high pressure high temperature liquid ref. Po ba? Or high pressure Low temperature liquid ref. Na po sya? sana po masagot nyo salamat ,dito po kasi ako nagugulohan sa condenser
High pressure sub cooled liquid po sir.. ang liquid temperature po natin jan ay below saturation. Para sa akin po sir, ang correct term po ay, HIGH PRESSURE SUB-COOLED LIQUID .. minsan kc sa mga term na ginagagamit tau nalilito.. salamat po..
Ilan ba dapat ikarga sa aircon pagkatapos mag charge.
Hi sir rolitz, kung karga po ang pag uusapan sa aircon, dipindi po yan sa capacity ng aircon mo po. At kung para sa akin naman po, may nameplete po ang bawat aircon at nakalagay po jan ang amount ng freon na kilangan mong ikarga po. In oz or kilo po.yan po pinaka accurate.
Nakatulog ako sa tagal mong magpaliwanag boss. Ayan tuloy wala akong natutunan.. Haha..
Bisaya ka master?
Oo bai.
Tagal mo nmn paliwanag
Malamang expert po kayo kaya natatagala po kau sir..this video po is for those beginners. Thank you anyway
mali ka rin isa ka pa
Good day po, salamat sa comment po. But may I know po kung anong mali at ano po ung tama? Gusto ko pong mapakinggan ung tama para sa inyo.salamat
How qualified you are telling Reftech some mistakes he made, can you please point out what area, if he miss something that doesn’t mean the person are wrong. Salute this kind of person showing and sharing his knowledge to the public, I been watching his presentation and is not for me correct him if he miss something. Just ignore people who can only see small infractions and didn’t see how did you donate your time for free. Keep on going sir, I have a master 1 refrigeration and I’m still learning some of the latest technology. Thank you sir.
If you see something better than everybody have your channel loaded with what you are doing on HVAC/R and shared it, let us see how do you present yourself using proper technician lingo. You can just say you missed something and pen point which part that way he can go back and made some corrections, or you can make a recommendations to make it the right way. Reftech HVAC/R and I are waiting for your smart response…would ya??? Just wondering how did you come up with that name MAMA since you are a father yourself.
Why Indian ppl love background music? It's very annoying 😒
Na subscribe na po kita sir pde po ba kita message sa messanger...salamat sir new tech lang po diy lang
Leoj jas po,, salamat din po sir
