DC Inverter Aircon Thread (Aircon roundup and FAQ on page 1)

  • Still using the AC despite a cooler night weather. Probably because of relative humidity pero natitrigger ang allergic rhinitis ko pag di gumagamit ng AC, tipong electric fan lang. To add, regulated talaga ang indoor temps.

    Heaven sent ang dry mode ngayong tag ulan.


    OT lang sir. Para di matrigger allergic rhinitis kapag nakaelectric fan, wag mo itutok sa mukha mo yung hangin. Pwede itutok sa floor malapit sayo, or sa legs mo tapos umiikot. Yun advice sa akin ng doktor ko. Pero ano pang silbi ng electric fan sa ganun no? Lol
  • Finally! Napalitan ko na rin yung insulation ng AC. Bumili yung kapatid ko ng monitor tapos may kasamang styrofoam. Medyo makalat dahil sa pag-hiwa ng styrofoam pero sulit naman kesa bumili pa. Napansin ko rin nag-lessen yung vibration ng AC sa windows tas yung high-freq noise hindi na rin rinig. Napalitan na rin yung breaker to 15A.

    Let's hope na maglessen pa rin yung kuryente though. Naka 21-23C palagi yung AC. Hindi kami nalalamigan sa 24C pataas. Eto config namin
    Morning/Afternoon
    23C
    Fan2
    Min kwH: 0.5kWh
    Max kwH: 1 kWh

    Night
    21C
    Fan1
    Min kWh: 0.3kWh
    Max kWh: 0.7kWh

    kWH consumption namin per day is 5-7kWh

    74.1kWh siya currently with 1 week, 8 hours and 47 mins usage.

    Take everything with a grain of salt though. Sa LG app lang gamit ko for tracking energy consumption. I know hindi siya accurate. Estimate lang siya but I'm sure nasa ganung range rin yung actual consumption

    Edit: Also ask ko lang. May way ba para macheck kung kelan na-manufacture yung AC? Wala kasi sa sides nung AC yung manufacture date. Gusto ko lang malaman if 2020 model yung nakuha ko LG LA200EC model

  • Lahat ng EC models are 2020 AFAIK. The WC models are the ones 2019 and below. Bagay nga siya sa 2020. EC=Enhanced Community....
  • Bought Unitech 2.5HP WT sa Sta. Mesa. As per Edgar (salesman) may 2HP and 2.5HP na available pa. Within next week daw may dadating na mga lower units.

    Ask ko lang, ilan amps ng breaker ang recommended para dito? Also, ilan W ang max consumption nya? hindi ko napansin yung label sa side ng unit eh..naging busy ako kakaikot sa mall, dami nila pala items dun. haha!
  • @skz

    Also, ilan W ang max consumption nya?


    I have similar Unitech 2.5hp . Nasa 2,000watts yan. Hindi ko na makita yung printed specs since nainstall na and I forgot to take pics beforehand. Pa picture & post naman nyan unit specs mo kundi mo pa na install.





    Here's the specs of its twin Kolin:


  • @musicgeek

    sige sir picture ko before install.

    ilang amps po ng breaker ang gamit ninyo sa unit nyo?
  • How to Calculate an AC Circuit Breaker <click here for link>
    Step 1

    Check your air conditioner's wattage in its specification sheet. Write down the maximum wattage it uses. If it doesn't mention wattage, check the SEER rating of your air conditioner and the cooling BTU number. Make sure you use the input BTU and not the output BTU, if both are listed. Divide the input BTU of your air conditioner by the SEER rating to get the amount of watts it requires, and write that down.

    Step 2

    Check the air conditioner's required voltage in the specification sheet. If you don't see a voltage requirement, check the plug on the air conditioner. If you see a normal household plug on it with three straight prongs, assume 120 V of power requirement. If you see a plug with two diagonal prongs and one straight prong under it, assume 240 V of power requirement.

    Step 3

    Divide the wattage number from Step 1 by the voltage number from Step 2. This gives you the amount of amps you need your circuit breaker to resist.

    Of course you'll need to add some allowance on top of the rated amps of your aircon. For conventional WT aircons, it's usually double the rated amps to cover for inrush current. But for inverter AC, a 1.5 multiplier is often more than enough..

    Here's one that is even more detailed and also provides a chart for what supply wire to use as well.. Sizing an AC Circuit Breaker <click here for link>

  • Good day po mga sir.

    Nakabili na po ako ng inverter AC, yung Panasonic po na nasa 1st page, 1.5HP.

    May mga tanong lang po ako.

    1. Ok po ba itong breaker na nabili ko?



    2. Wire: stranded, size 14

    3. Pwede po bang i-tap ang wire galing outlet saka idadaan sa breaker? Safe po ba ito?
  • @onat

    1. Ok po ba itong breaker na nabili ko?

    Better if RMB15C/O or RSB15C/O dahil sobrang taas yan 32A for a 1.5hp aircon.. Sunog na yung aircon, di pa nag-trip yung breaker nya..
    2. Wire: stranded, size 14

    Ok if this is THHN/THWN wire and hindi yung AWG14 na flat cord. AWG14 (2.5mm2 x2) na royal cord is also okay.
    3. Pwede po bang i-tap ang wire galing outlet saka idadaan sa breaker? Safe po ba ito?

    Uhm, no. Doing this would mean that your AC will be added sa load ng CO breaker mo. Most big houses have a 20~30A CO breaker sa panel board. If pati yung aircon mo ay doon kakabit, you run a high risk of tripping the breaker once dumami ang devices na nakaandar. This is even more dangerous if you paln to continue using yung outlet tapos doon naka-tap yung aircon.

    Assuming that your AC isolation breaker is 15A, it should be wired directly to a dedicated 20~30A breaker sa panel board.

    There should be an ascending hierarchy when it comes to safety breakers..

    Wrong hierarchy:
    Aircon > 30A isolation breaker > 20A panel breaker > 65A Main breaker

    Correct hierarchy:
    Aircon > 15A isolation breaker > 20A panel breaker > 65A main breaker

    Ibalik at palitan ko na lang ng mas mababa. 15A o 20A?

    Nasabi ko na po na gumawa ng dedicated na linya para sa AC.



    Maraming salamat sir sa mga info.
  • @Godai_Yusaku

    salamat sa input sir. 20A ginamit ko.

    @musicgeek

    here's the image of the label and also error codes na din for reference:

  • ^Thanks @skz & congrats with your purchase . Around 42k yung 2.5hp known brands rebadged Gree nyan like Kolin at Ansons. Even higher sa Abensons.





    Very nice find indeed by @Godai , @kompressor & others here.
  • @musicgeek

    opo nga sir sulit sya sa presyo.

    Napansin ko din na yung label sa fan motor nya is rated at 190W @ 220V. So yung compressor lang pala ang inverter pero I think hindi din naman din ganun kalaki ang difference ng konsumo sa kuryente sa dual inverter na unit. correct me if I'm wrong on this
  • 15A o 20A?

    RMB15C/O or RSB15C/O HINDI po RMB20C/O or RSB20C/O

    @musicgeek; skz

    Congrats sa super panalong aircon nyo! Hehehe
  • RMB15C/O or RSB15C/O HINDI po RMB20C/O or RSB20C/O


    Copy po. Maraming salamat po ulit.
  • Nagbibigay ba si Daikin ng accreditation sa individual (hindi shop), papakabit na sana kami ng Dsmart. Pinaka mura Kong nakita is 36500 including installation. Yes queen na siya sa r&j haha pero yan na kasi pinaka mura sa cavite, ayoko na lumayo pa kasi mahirap na pag nagka problem, baka matagal maservican, accredited dealer naman yung shop nila.

    Pero yung pinsan kasi ni mama, nag ooffer din ng Daikin, accredited daw sila kaso wala ata silang shop haha kaya ko natanong yung first question ko about sa accredited individual. Actually mas mahal nga sa kanila eh kaso since relative naman, parang willing na mga tao dito sa bahay na iletgo yung konting matitipid namin. Hesitant lang ako kasi di ko masigurado if totoong accredited installer nga sila since puro shop lang yung naka display sa accredited dealer page ni Daikin.
  • @king solomon :)

    if you will buy your daikin at r&j's, sop nila na sila ang mag-install nyan. hindi sila magbenta at papayag na hindi sila ang mag install. besides, included na naman yun installation fee sa AC unit kay r&j's, pulido pa ang trabaho.
    also why would you risk the warranty with those peeps na "accredited daw."
  • @king solomon

    Just ask for his accreditation certificate. If wala, then proceed with doon sa nakita mo dyan. Tulungan nyo na lang yung kamag-anak in another way.
  • Ty mga sirs. Go na ko sa unang nakita ko
  • @KSolomon

    I agree with @statix and @Godai to make sure to have your unit installed by authorized dealer / installer only . Marami pretenders so beware as aircon manufacturers will not honor warranties dealt by fly by nights.

    I suggest you check with Ray J if they can reach your location given nearby province lang naman kayo. They are still your best option both for price and competency.

    BUT if you insist with other dealer installers specially those not posted on manufacturers website, you can contact their sales office to verify. Here are the point persons from Daikin PH i coordinated with when I bought my unit last year. Rose provided me with product information while Nestor helped me to validate the dealer / installers. Actually si Nestor nagsabi sakin na maayos talaga kausap si Ray J that lead me to eventually buy from them.

  • Hi! New to this forum.

    We have a room that's around 7.5sqm, pero kinoconsider rin naming buksan yung pinto minsan para pati ung sala/dining (15sqm) lumamig.

    Alin po ba pinakasulit among the three?

    What they have in common: Window Type Inverters

    A: Compact Sized 1HP (EER: 12.3)
    B: Normal Sized 1HP (EER: 11.8)
    C: Normal Sized 1.5HP (EER: 11)

    true, i myself would be an example. palpak na nga trabaho, napamahal pa.
    pinalagpas ko na lang kasi hindi nga iba. hindi na lang talaga mauulit.

    1. How big is the sala/dining area?
    2. Gaano kadalas ang minsan?
  • @boss godai

    i think you are quoting a post para doon sa kabilang thread(anong maganda brand ng aircon)? :P
  • 1. How big is the sala/dining area?
    2. Gaano kadalas ang minsan?


    1.) 15sqm
    2.) Siguro mga 5 hours/day, 5 days/week?

    Pero kaya ba ng 1.5hp mapalamig un lahat? Malaki ba impact ng EER difference nila? If closed ang kwarto, alin mas okay?

    Salamat po sir sa pag sagot :)
  • 1.) 15sqm

    15 + 7.5 = 22.5 <-- If you are thinking of doing that in a pansamantagal arrangement, then you should consider the total square footage instead of just the bedroom. At 22.5sqm, you will need to get at least a 2hp (better if 2.5hp) aircon. Aside from that, you will need to install an exhaust fan sa wall ng bedroom para magkaroon ng return yung hangin pabalik sa bedroom while the cold air is pushed out into the sala.
    2.) Siguro mga 5 hours/day, 5 days/week?

    If your budget is only for a 1.5hp aircon tapos papalamigin nya ang 22.5sqm space for that long, balewala ang savings ng inverter unit. You might as well just buy a conventional aircon dahil it will be undersized for such a big space.
    Pero kaya ba ng 1.5hp mapalamig un lahat? Malaki ba impact ng EER difference nila? If closed ang kwarto, alin mas okay?

    Obviously NOT. Bumili ka na lang ng 1hp for your bedroom then buy a separate 1.5hp for the sala. With your plan to cool that adjacent space, EER won't even matter dahil andar lang nang andar yung aircon nang walang katapusan.

    If maliit ang budget at pansamantagal ang plano, just get the 2.5hp Unitech unit and use that to cool both spaces in an intake/exhaust setup. Overkill nga lang kapag nasa bedroom na kayo sa gabi, but it will still be cheaper in the long run.
  • Bumili ka na lang ng 1hp for your bedroom then buy a separate 1.5hp for the sala.

    Salamat sa pagsagot sa mga inquiry sir, laking tulong talaga :) So, out na ang 1.5hp since di talaga kaya ang space.

    If kwarto lang palalamigin sir, ano mas maganda sa dalawa?
    A: Compact Sized 1HP (EER: 12.3)
    B: Normal Sized 1HP (EER: 11.8)

    If maliit ang budget at pansamantagal ang plano, just get the 2.5hp Unitech unit and use that to cool both spaces in an intake/exhaust setup.

    Walang unitech dito sa amin eh :/

    B. Even better if you will get the TCL 1hp unit from ESLA.

    Too bad walang Unitop dyan sa lugar nyo. Super laki na sana ng matitipid sa purchase price.
  • B. Even better if you will get the TCL 1hp unit from ESLA.

    Copy sir, salamat talaga!

    Kamusta po ang tibay and aftersales support ng TCL and other lesser known brands (ie Midea, Unitech, Gree, etc)?
