I am sorry sir, but I have ti disagree with you in some procedures, statements and explanations that you have mentioned in your video. I will save the other matters for the meantime, considering that your work in the video is pretty well appreciated by the viewers including me. First, the refrigerant condition in the evaporator (freezer) is at low-pressure, low-temperaure state. Not low-pressure, high temperature. Second, you did not mention if the compressor should be working or not if you are to re-charging a refrigerant in its vapor-state or liquid state. Another thing is, where do you tap the hose when you will do the liquid charging? This is supposedly a very imprtant part of your video. Third, vacuum pressures are not mentioned as negative if you are using inches of mercury units. They are plainly measured from o to 29.92 or practically 30.0 in. Hg. If you use inch Hg unit in vacuum pressures, it is understood to be partially vacuum . Negative numbers in partial vacuum are used as layman's terms if they are referring to SI units. Oftentimes they use 0.10 to 0.99 bar, indicating that it is below 1-bar absolute pressure. Fourth and final hopefully, in all aspects of analyzing the condition of a refrigeration system, it is always the pressure that we depend upon. Not the temperature, and not the amperage. Temperature and amperage readings only come handy as secondary to the working pressure. What do I mean by these? You should be using apressure-temperature table or chart to better understand if the system is operating normally or not. I would like to mention also as to how do you remove the charging hoses - the low side and the high side; is it while the motor is operating still or when it is turned off and wait for some more minutes? If you ought to teach other technicians the step-by-step procedures of charging a refrigerant system, I suggest that you please include them in your next video or if you will edit your video. I a m a person who appreciate people like you who put some efforts, time, and money to educate other people in technical areas like refrigeration. That is why I am giving comments such as these. Deep in my heart, my comments are well meant. Thank you.
Tama po kayo sir.. baliktad po sa kanya..paano naging low temperature ang high pressure.. at high pressure naging low temperature.. .. dapat high pressure high temperature at low pressure low temperature.
Napaka galing mag explain sobrang nakaka tulong .. magaling mag turo kumbaga pulido at madaling maintindihan sa mga nakaka relate na nag aaral plang ng technician.. good job idol ..
ang lupit nyo tlga mag paliwanag..first time ko lng manood sa tutorial nyo nawili nako manood..dami ko nattunan sa inyo..sinubscribe ko kaagad at alam ko maraming mattunan sa inyo..
Sir napakagaling at mahusay Kang magturo ,,👍👍 ,nag aral din ako sa non formal educ, maayos Naman magturo Ang instructor namin ,,pero iba ka sir .mabilis matututo Ang studyante mo 👍👍
salamat po dami ko natutunan.. hirap na magtiwala sa ibang aircon tech. 2x na din ako nadenggoy 8700 yung una. 2700 yung pangalawa. ang resulta hilaw parin ang aircon ng kotse.. buti oo may ganito tuturial mag diy na lang ako.. bili nalang din ako gamit. tnx po at mabuhay kayo..
lods maraming maraming salamat.. sa tutorial.. Godbless.. hayahan lang po mas marunong pa sila.. pero i know hindi po yun ang sukatan.. ang sukatan po jan ay. kung sino mas mabebless.. kung sino po pinepersecute.. ay siya lalo ang itataas ni lord.. kaya kampay lods.. More more blessing pa po darating sa inyo.. marami salamat po.. ulit hanggang sa muli..
Sir ung ref. Po. Samsung na inventer pinagawa q po dhil di na magyelo tpos ung gumawa ngkarga lng sya ng freon tpos ayaw na po umandar ng motor ng ref q.
ito yong dapat panoorin , ito yong saktong process sa reprocess medyo na kulangan lng ako sa vacumm part yung e open yung high side 1st to determine if barado ba ang system o hindi then yung initial charging sa highside na pwede liquid hehe pero goods parin kay sa ibang tut more power
Bagong Refrigerant na ata si r600a... kakabili ko lang ng personal 3.5k cubic na ref. R600 din siya at di siya inverter... salamat dito pinaplano ko din sa ref ko kapag nawalan ng refrigerant ako na magkarga.. same procedure lang din pala sa mga a/c sa work ko sa hotel..
ANONG MALI SA 2:30 WLA NMAN KSE HIGH TEMP PDIN KSI HINDI PA NAG BOBOIL ANG REFRIGERANT BANDANG GITNA NA MAG LOW TEMP ANG REFRIGERANT. CORRECT ME IF IM WRONG
@@rasssike5941 panuodin mo ulit kung paano nya I explain yung part ng evaporator, Never ka magkaka high temperature sa evaporator nasa part ka ng saturation or latent heat baka Superheated refrigerant pa pwd. Pwd mo din i search ito Superheat Subcooling Latent Heat Sensible Heat Saturation refrigeration cycle na yan =)
Sempre idol lagi ako nag aantay sa new vidio mo pag walang magawa eh un mga dati mo vidio ang pinapanood ko sau ko nlng kasi nakikita ung panagarap ko mag seaman ee
Number twenty-eight...👏🕊👍 Two-one-seven viewed po kalecky...😉 Nice demo, informazyuniz tipz... 04:43 - anung refrigerant use nyu po jan sir? Phaze-out na po now c R-12 sir, hehe... Hindi nyu po yata na kabitan ng clamp-ammeter while nag karga po keu huh...😉💥✌
Sir, meron kbang videos about sa refrigeration plant onboard ship? Any troubleshooting or even charging ng refrigerant sa refrigeration sa barko? Thanks Boss 😊
Ang ganda ng tutorial mo dto sir ah, sakto dto sa ref namin na nagleak samsung din inverter, my tanong lng ako sir kung tanggalin ko yung filter drier hinangin ko siya, diba sasabog yung compresor sir kc R600a nga yung freon niya pls sir sana mabasa muto at masagot tanong ko salamat ng marami, marami ako natutunan
Maganda pagkakagawa mo sir. Pero hindi ako sang ayon sa pagka explain mo sa refrigerant cycle dapat kapag pumasok sa low side ang state ng refrigerant ay magiging low presure low, low temp. Vapor gas hindi low pressure high temp. Gas.
Correction lang po, after po ng capillary tube/expansion valve, ang state po ni refrigerant is low pressure low temperature liquid po. After compressor/discharge linr pa po ulit siya magiging high temp/high pressure vapor.
Nice, thks very informative. Nag subs na rin ko sayo. Ang Kelvinator namin ay hindi rin lumalamig pinalitan ko na ng starter relay and overload, hindi parin mag start ang compressor, and suspetsa ko ay kulang ng refrigerant. May napanood ako at doon ako mag add ng refrigerant sa suction line gamit ang piercing valve with adapter. Tama ba ito Tol? Thks
Sir ask lang.. ngayun kulang alam to.. sir sabi daw nila pag nag karga ng refrigerant sa suction kailangan daw i taub yung tangki para makapasok c liguid...taz ngayun sa video mo bawal pala ang liquid sa suction dapat pala gas lang papasok? Puede parin ba itaub ang tanki mag charge nag refrigerant? Sana masagut commet mo sir.. salamat
sir ang pagkakaintindi ko sa refrigeration cycle pag nasa(condenser) discharge line o high side ang refrigerant,automatic magiging liquid form na sya then papasok ng capillary tube para macontrol ang refrigerant na maging gas form pag pasok nya ng (evaporator)low side at pag may nakalusot na liquid form refrigerant dun naman sya maiimbak sa accumulator para maging gas pag pasok nya sa suction ng compressor para hindi masira at mahirapan ang compressor na icompress ang refrigerant then another cycle na naman same process.thank you.
Sir tanong lang po bakit yung ref compressor ko na panasonic ay 4 ang line bukod pa yung service valve d66c12gax6 model ng compressor diko ko po ma gets new lang nag aaral
I want to know kung ilan yung Pressure na Ilalagay during pre charging, and Kung after pre charging ay pagaganahjn naba Ang Unit? Also for Checking lang Po ba ng Pressure yung Sa High side Guage? No need napo ba Mag charge ng liquid? Kung sino po makakasagot napakalaking Thank you po agad,😊
Boss pano po malalaman kong need n kargahan ng refrigerant ang isang compressor? 3HP ang rated ng condenser/compresaor s pag gawa ng ICE BLOCK., salamat Boss...
sir gud pm ok lang ba na hindi gumamit ng clamp meter habang nag charge ng freon yung gumawa ng ref namin gumamit sya ng clamp meter importante po raw yon
Good day po sir, thanks sa tutorials. 1st time ko po maka encounter ng r600 fridge, nakakuha aq ng idea dito sa inyong video na negative pressure sya. After ko mag hinang sa evaporator, nagflushing, palit filter. Nag initial charge po after ng vacum hanggang itinama ko na po sir sa (-1psi). Ok po sya hanggang almost 2hrs, bigla po nag (-20)?
Sir possible ba na may leak kapag vacuume pressurized, pero kapag high pressurized wala naman leak? Anu kea nangyayari sa car aircon system ng advi ko? Ganyan kasi nangyayari, nung nag vaccume na ko at observe ko for 5 minutes pa lang may bawas na vaccume pressure. Pero kapag naman kinargahan ko compressed air up to 50 psi sa low side wala naman leak kahit 15mins. Baka may malupit kang idea sir na lumusot sa kin hehe
