What to do with 50hz appliances?!

[baloy]

Hello po! Ask ko lang po kung may parts ba na
pwede palitan para magamit ng maayos dito sa
'tin ang mga 50hz na appliances? O may device
ba na pwede gamitin para magamit sila ng
maayos?

I brought home 1 refrigerator and a hair clipper
from Dubai kasi, di ko napansin na 50hz lang
sila. Afaik, 50-60hz dapat ang gamit dito sa 'tin.

As a result kasi as i observed, di masyado
lumalamig yung ref namin. Then yung hair clipper
is mahina yung andar nung motor.

Anyone?! tia....

[brian_po]

replace the compressor..
that would be the best solution. magiging mas efficient pa sya

[baloy]

pano malaman yung compatible na compressor
sa ref ko sir? ano dapat ko tingnan?

tia...

Dapat lalamig un dude. Kase mas mabilis iikot ung compressor. Bago tayo magisip ng frequencies dito mag check muna tayo kung may karga na freon. Baka due sa handling process/leak or something nasingaw ung freon at wala na itong laman.

You mean baliktad pag 60Hz compressor sinaksak mo sa 50Hz mas babagal ung takbo nya at baka nga hindi lumamig.

Bakit baloktad ang nangyari sa apps nyo, dapat nga ^  bibilis ang ikot ng motor ng hair clipper nyo, try check ang line voltage nyo baka under voltage ang lugar nyo.

Honga bibilis dapat yan. If you have a 60hz compressor tapos ginamit mo sa dubai na 50hz curyente nila babagal ung takbo ng aircon agreed ako sa ganito. pero baliktad if you have a 50hz compressor tapos sinaksak mo sa 60hz compressor eh dapat bibilis un ng onte.

fyi, hindi bibilis yun.
the compressor is designed to run in a 50Hz Frequency.
hindi nito kaya i handle ang 60Hz. stressed ang motor sa ganyan frequency.

compared to a inverter Ref. it is designed to handle a 20Hz to 120Hz Frequency.

@TS.
check the LRA of the compressor.
that would be your reference in replacing your compressor.

Technical stand point it will run faster. If it will work or not, it would really depend on make and brand perhaps... Of course the motor will be more stressed and most likely not to the intended design. Pero in general an AC motor regardless of what type will run faster with increasing frequency and vice versa. Kung kaya ba talaga ng motor bumilis depende nalang sa design and concept. I know this fact because I have a german refrigerator at home and they are the older models (Built 1992 and is now 12 years old) and have 50Hz rating on it, I'll make a pic (dunno kung makikita pa name plate) but don't laugh on how bulok it looks since I use the ref for subzero treatment sa bakal. It runs a bit louder than the usual ref. You might be familiar with the american designs that perhaps cannot endure the stress. On the other note my wife has a japanese ref from japan and it runs also on 60hz. May transformer nga lang. Nagana din sya....

Paiba iba kase bro. Even our washing machine at home is 50hz italian made. Nasa make talaga. I have another german friend who bought german washing machine 50hz hindi naman nagana sa pinas. This was because it had mechanical timers that used its timing na galing sa lines (What happened is that it finished faster than it should).

Siguro nagkataon na witness mo ung sirain na ref or hindi maganda na brand.


But putting make and brand aside kung hindi lumalamig at tumatakbo naman ung compressor by touching it, hindi mahirap kc icheck kung may laman na freon. It's the first thing that I would do..

Also here is some internet proof to what I am trying to say..
Here is proof that a 50hz compressor will run faster in 60hz..

And this applies for air-conditioning unit as well.

So before replacing something costly try troubleshooting if the compressor runs at all. If it does run then that's fine. Pacheck nalang sa isang refrigeration expert or kung gusto mo DIY check for low side pressure reading which should be in the 40psi region when compressor on and high side pressure should be over 150psi (I don't memorize exact value). This should indicate or tell you that your compressor is working fine or not. Also check what type of freon to use. If it's bnew it's probably using R134A if older system perhaps R12. Some refs also don't have nipples to do the connection so you might need to make a nipple for refilling the freon. And finally make sure you evacuate all the stuff before refilling the system up.

Another thing is also that you should put less freon in a 50hz ref. Since the compressor will run faster hence build up the pressure faster. Therefore you could try and compensate with lowering the pressure to not hurt the compressor mechanism too much. But sa case ko.. Wala ako ginawang mods..Sinaksak ko lang tapos.

bibilis nga yung motor f proportional sa RPM ng motor(f=PN/60,ac gen formula,AFAIK).

Pwede rin baka 240V ang rating nyan, tapos 220V lang tayo at kadalasan under voltage pa.

Hindi rin. In europe dati 220V ginagamit tapos naging 230V tapos today lahat ng supply in entire europe 240V na. No issues parin. But this is stepping up so stepping from 240 to 220V is 20V difference which made no effect sa mga equipments.

Without load okay lang, pero pag-mayload na ang motor may epekto ito sa torque (N-m), power (VI), speed (RPM) capability ng motor.

   kapag 50 hertz motor  connect mo sa 60hertz bibilis ang rotation ng motor.dito sa Kuwait may dumating kaming product made in USA na books & documents preservation machine may 2 hp na compressor.ang gamit niya y freeze niya ang mga old books documents tapos defrost niya sa normal temperature para ma preserve ang mga old original documents & books.
   Ang voltage dito 240volts 50hz.pinipilit ng supplier na pwedeng umandar ang machine w/compressor na 220volts 60hertz sabi ko mag overheat yan kasi di tama ang rotation noon try nila 5minutes lang nag overheat na ang compressor motor .Para magamit  ang machine bumili kami ng UPS na 1kw ang capacity ang frequency range 30-80hz yon mag 3 years na walang overheat walang problema ang machine & compressor.
 Sa philppines may nakita ako sa cdrking na AVR Power Capacity: 1000VA
• AC input 110V (75Vac ~ 145Vac) or 220V (145Vac ~ 280Vac)
43Hz ~ 67Hz
 pwede ito sa mga 50hz na may capacity below 1kw kasi kailangan ma maintain ang frequency na 50hz ang tolerance nito AVR 43Hz ~ 67Hz
