Very good mga iha at mga iho. I am a college professor here in KSA teaching ME and Refrigeration and Air Conditioning subject too. I was a college professor in the Philippines and was also repairing RAC system before I decided to work here in the Middle East. Nakakataba ng puso na makita kayong nagpupursige sa paggawa ng tutorial sa KZfaq. Marami akong napapanood na tutorial kuno pero marami sa kanila ang hindi "agreeable" ang mga sinasabi at tinuturo, at may mga procedures pa sila na di ayon sa SOP ng RAC servicing. Keep up the good works mga ineng at mga iho. If you have a group for RAC matters and subjects, I am most willing to share mine para makadagdag sa inyong kaalaman lalo na sa theoretical lectures ng refrigeration. God bless sa inyong lahat.

Very informative video. Thumbs Up👍👍👍.

Pwede na yung ganitong methodology sa domestic application not in commercial and industrial. Not so proper way how to charge the refrigeration system. But this works naman, "Diskarting pinoy" maraming kulang na procedures, I can tell na this is "veterans move"

this is very informative especially for professionals who are currently not in the field of RAC. im actually taking notes from each tutorials.

Ganda nmn ng technician 😍

Di bali na mababagsak ako sa kanyang classes na maraming beses basta ganyan ka ganda ang instructor ko.

Very informative. Watching fr. Dubai .

Idol... prehas tyo course...BSME ...TIP qc... graduate n ako..at working sa bulakan s isang planta ng coal power plant......nice video balak ko kc mag diy sa car at ref at aircon ko.... gusto ko matuto din..

Ang galing nmn magturo. Nice instructress

very well explained. thank you miss beautiful for sharing info.

Ang ganda ng pagkapaliwanag.matututo ka tlga.nice one.

Glad to see women’s given a chance to show their potentials, we know this trade mostly known for the men. I’m not gonna make a comments what are the proper procedures because where am I is different, almost everything are affordable and even provided by the company. The leak detector bubbles should be more thick because that won’t stay where the micro leak is and drips can’t find the bubbles from the leaks. Pressurizing the system following the manufacturer recommendation are important because you could blow up a coil or the parts of the compressor. The R410A refrigerant are blend composed of equal parts R32/R125 zeotropic means boils at different temp. When the technicians found out that system not cooling, you don’t wanna jumped into conclusion that the system needs refrigerant, that is the last resort you can do after a series of diagnostics. Then when you found the leaks, just don’t charge it, because what happened the possibility is one of the components are fractionate and that will reduced the system capacity. Recover if there is leftover and don’t pulled a into vacuum because you are pulling the outside air, but don’t worry R410A with its pressure mostly are already gone. Pressurized the system, if leaks found, fixed the leaks, pressurized again, released the nitrogen, and pull a vacuum. Observe the needles or better off with digital manifold so you can see the increments, few psi rise doesn’t means you have a leaks, then please have a weight scale because mini fridge or even the household size fridge are critical charge. Some may takes few ounces or less than a pound (1 lb= 16 ounces), sa Pinas gumagamit tayo ng Kg. For complete job operations you might have to replaced the capillary tube, para sigurado walang bara sa system. Talking about the R22, man this refrigerant are perfect because there is no temperature glide, you can charge the system by vapor or liquid, the only things government around the world I don’t know about China, there is no regulations over there, stopped producing this refrigerant and everybody knows. Luckily before the R22 price sky high, I was able to buy and stock 15 tanks, you still can use until you are running out of it. There’s a lot of retrofitting today by just changing oil on the compressor, change the TXV like using R407C, the temperature glide almost the same. The MO99 just charge it from R22, is just a little bit temp glide difference. Anyway, this lady with her beauty my man, could be the men biggest distractions looking at her beautiful face, is she single???. I could be a big follower on her video, keep up the good works lady, this trade will no longer a men’s job alone, women can do better than men in every way. I don’t mind going back to the school everyday if you found someone teaching you and found something more interesting para sa puso natin . Nakaka I love naman and ganda nya maliban sa smart pa. Just head ups to this beautiful lady be a model yourself, have a safety glass and gloves on, tied up your hair to avoid being got caught on the moving parts.

Maam salamat po. At shinishare mo ang kaalaman mo

yung modelo ang tinitingnan ko kasi ang ganda hahah by the way thats amazing! thankz a lot for the video

ang ganda ng teacher hehehe.di na ako aabsent dito😂😂😅

Thanks you ma'am marami na akung matutunan sa inyo. Kahit Hindi na mag tesda. Haha

Nice channel

Ang ganda ng paliwanag sa toturial mo maam.salamat sa dagdag kaalaman God Bless

ito ang karapat dapat magging tesda teacher.

Very informative, shukran maam

Video very nice

Hi madam salamat PO sa kaalaman, God bless!!!

Thanks for sharing this video...so nice tutorial po❤️

So nice

Great job

Salamat Madam may natotonan naman malaking tolong pa sakin Godbless po

Wow lupet ni ate..lodi😅

Nice, I'm your new subscriber 👏

Ang galing galing mo nmn idol

used 1/2 hose and quarter inch connector, micron gauge, and Schrader valve core removal tool, and evacuate below 500 micron, wait then break the vacuum by 2psig dry nitrogen gas then vacuum again. used hose for vacuum only in order to avoid contamination from other refrigerant. micron gauge is a MUST! remember we using poe and pve oil now which is hygroscopic. it grabs moisture and change it to acid through hydrolysis when long exposure to moisture and when not properly dehydrated below 500 Micron. POE OIL is notorious on this. also used acid tester if suspected oil break down.

God bless po sa inyo

Ty sa trivia. Brand pala yung freon

This is a very informative video. Could you please please put a caption for this video?

hello maam..ang galing2 nio poh

Very informative po thank you for sharing this video.

Nakaka bilib ka nman miss Arian kc Ngaun Lang aq naka kita nang babaeng technicians eh galing Napa Amazes aq sau hug na kita stay aq sau god bless

Master pwdi Slit Type Aircon Naman Ang Cargahan mo Freon Sa Next Vlog mo thank you and Good Bless YOU

Thanks mam for this video.

galing ni mam.love you mam

Ayos,,salamat po....;)

Hi madam i am your new subscriber. Keep safe always.

Keep watching and support especially Ads from Al Khafji Saudi Arabia 🙏

maynatutunan naman ako saiyo

Ganda ni teacher

PPE na lang kulang hija kahit latex gloves lang sa kamay..(frostbite In case of leak) at sana ma admit anak ko sa College of engineering (ME gusto nya) dyan sa PUP sta Mesa this coming SY.. Stay safe!! Proud alumnus Here...

thx u

Galing nman ni mam asawa ni sir

Thank u maam

Nice

Hind dapat ginagamit ang high pressure gauge during system vacuuming, dahil wala naman negative pressure yan Kaya masisira ang high pressure gauge mo kung lagi mo yan gagawin.

sobrang laking tulong mga lodi

Tnx for sharing enge

Thanks po maam,ganda nyo po

anymore it's like half of it is good and half is not also after a few hours it wont blow anything at all then the bottom part is wet. please answer 🙏

Pa shout nga name ko ate 😁

How much pa charge Window type R-22 19 oz?

Hello. Congratulations on your very clear and easy to understand video tutorial. May sira akong 1hp na split type aircon (Panasonic) 2010 model. Gusto ko na siyang i-dismantle. Ano ba yung "Pump down" at kailangan ko bang gawin ito? Mayroon ba kayong tutorial ng tamang pamamaraan ng pag dismantle ng split type aircon?

Ang ganda mo po

Ano ba ang tamang position ng tangke ng r22 during charging? Gas? Liquid

ask lang po maam.san po nka kabit un hose na highside gauge manifold? slamt po sa sagut..

New subscribers More video about air-conditioning. Im refreshing knowledge also about theory next vlog po ethalphy naman po

❤️

Maam baka pwede mag vlog ka ng car aircon maganda kc explanation mo

Pa request sa mga air con Anong part Ang Laguna sisira

Gudam new subscriber here. Ask ko lang kung graduate ka na? Nagsubscribe ako kasi para nasa skul ako while explaining the subject unlike others experience at technique ang tinuturo nila. Keep it up and gudluck

Ask ko lang po, hindi na po ba gagamitin ang high side Guage sa charging of refrigerant?

Ma'am San mabibili ang charging Freon SA water dispenser?

May training center ba kau ng RAC para ma kapag enroll kami

Nex vlog mo superheat subcooling

gdam po ask ko lng po kung ano po kaya ang possible trouble ng 4mos.old na inverter n ref pag bigla nlng nag off khit may power nmn po ang source salmat po s mabilis n reply.

Thank you mam ikaw na

panu nmn po pasingawin ang dating refrigerant ng A/C..salamt po sa sagot..

ang pagba-vacuum mam ay 500 micron below and break by nitrogen

Santa Po lagyan nyo Po ung play list nyo Ng step by step..para do Po kami patalon talon..salamat Po..

ang cute mo mam hehehe... tanong lang po.. yung high pressure gauge ba di na ginagamit pag magkakarga ng refrigerant? naka close lang ba dapat sya at yung low pressure gauge lang ang gagamitin pag magkakarga ng refrigerant? tama ba me?

Balang araw maging instructor ka husay mo...Sana maturuan mo ako. Akoy isang mechanic Po dto sa Papua New Guinea 🇵🇬 🇵🇬🇵🇬

Salam kenal

Maam saan po kinakabit ung clamp meter pang reading Ng Amper. Gusto mag Aral or practice Ng airconditioning

ask lang po mam ok lang ba na nka higa ang tank hnd ba pede nka tau ang tank ng freon.slamt po sa sagut

Madam may i ask..trainor ka ba sa Meralco Foundation o sa Dualtech

Have a bless morning, ok maliwanag man slmt, ang kailangan ko ilan ang operating pressure ng R 32... slmt

Maam ano ba ang tamang posisyon ng tangke ng freon tuwing mag kakarga tau? Tama ba ang nakatayo, nakahiga o naka taob?

Hahahahaha Akala ko ang freon yun na yun bran Pala yun Kaso nasanay na mga mandlang customer at technician hahaha

Pinakamalinaw na tutorial sa lahat.

Can you make a step by step video on how to store refrigerant into a condenser on what they called pulldown and also what they called reprocess?

Take note depende ren sa panahon base sa experience ko pag malamig ang panahon madaling magpalamig ang aircon at bumababa ang amperage at kung mainit at sobrang init ng panahon during summer tataas den ang amperage minsan lampas pa nga sa limit nya kase hirap sya mag tapon ng init na kinukuha nya sa isang room absorb naman ng refrigerant na nasa evaporator. Tawag dun heat transfer. Or Inalis mo yung init sa loob ng room tinapon mo sa labas yung ang trabaho ng refrigerant..

Madam anong mga refrigerant ang kailangan ay liquid charging o nakatumba ung gas cylinder

Informative video. Ask ko lang sana bat hinde kayo nagbabase sa kilo ng refrigerant kung parehas naman ang ipinalit na compressor o walang binago sa system. At saka sa pressure test sana may nitro para just incase na may leak, di problema ang pag vent ng refrigerant. Mahirap kasi pag may microleaks. Super heat/subcool, microns maybe para sa another level. But overall, ayos na din po yan. Kudos guys..👍

May tutorial video po ba kayo paano ang recovery system. Salamat po

Good pm.gusto kong gayahin vaccum pump.nyo.paano ba maiiwasan un lumalabas na konting langis.tnx po.

mam pina pumpdown din ba ang window aircon?

mam ppno if my laman pa n refregerant sa system pru mbaba n pressure need lng mg refill ng kaunti.. e vavacum ptin ba yun? kung e vavacum yun edi mhihigop yung laman lahat.. instead n mgddgdg lng nmn dpt ng kaunti pra m sakto yung pressure. ano po b ggwin pg charge kung my laman nmn ntitira sa loob?

Pag nag charging ba hindi na pwede buksan Ang high side?

Hi mam s mga malalaking bote po ng refrigerant dalawa po kasi valve.. May pra sa gas at para s liquid.. Khit ikakabit nating yung yellow hose sa liquid ng bote pro nasa baba nmn ang bote at nkatayo.. Gas prin ba ilalabas? Slamat

Salamat po mam sa inyong pagtoro marami po akong natutunan ulit sa inyo godblesa po

Madam saan pwd mag enroll sa oag gawa ng refrigerator at air-conditioning

hi, napasubo ako sa pag aaral sa AC dahil sa magandang pagkakatoro. thank you, tanong kulang meron ba kayong video kung paano ko malaman yong high side at low side ng compressor tama ba ako. sorry ha dahil wala akong background talaga.

Mam hindi po ba pdeng gamitin ung reciprocating comp. as vacuum pump?

bat tinumba pa ung refrigerant r22 ung isang istudyante di daw dapat baliktarin ang refrigerant tank tama un kasi vapor ang papasok sa compressor

Pano mag purging?.
