Re: Aircon - Are Inverter types worth it?
How about those energy saving devices ? I always wondered if these really work.
Speaking of energy saving devices I've researched a lot on these and tried it myself. I was able to save ±40Watts on a 1HP window type aircon. I've used 2X40µF, 1X14µF & 1X16µF run capacitors all rated at 370-450VAC. I used various ratings because i was experimenting on capacitor banks. What I've learned is the higher the capacitance value the higher is the energy saving. But there is maximum as to how many you can use. I plan to make a 4X40µF capacitor bank and have it centrally mounted on my distribution panel. I used a powermeter (/index.php/view+classifieds/id/3508047/Kill-A-Watt+/+Power+Meter?referralKeywords=power+meter&event=Search+Ranking,Position,1-18,18#advertisementDetails"> http://www. ***********/index.php/view+classifieds/id/3508047/Kill-A-Watt+/+Power+Meter?referralKeywords=power+meter&event=Search+Ranking,Position,1-18,18#advertisementDetails) to have an instant reading on devices. Parallel connection is the way to connect multiple capacitors. If the capacitors is left plugged without any load it will consume 4-7watts, so its best to use it only when there is a load (e.g. ref, elec. fan, aircons, compressors and the like). For a typical 16" electric fan this consumes ±50Watts, i was able to reduce it to ±30Watts. On my 10 cu.ft ref i was able to reduce the power consumption from ±135W to ±115W. Each 40µF-370VAC run capacitor costs P400, its expensive but i believe its worth it.
I bought an inverter split type a couple of years back and after a year it died. Need to replace 2 expensive parts that cost ₱10k. I ended up negotiating for a buy back option. According to some of the technicians, they are sensitive to voltage fluctuations. I replace it with a non - inverter type.

That's nice project. I believe you created a capacitor bank that modified your power factor. It's being used by many industrial company to lessen cost of electricity. Good one.

Re: Aircon - Are Inverter types worth it?
Hey bro kevlar what brand of inverter ac ang nabili mo?
I'm planning to buy LG HS-09iv inverter type.
Hindi ba na covered ng warranty yung nasirang parts ng ac mo?
Hi. It's Samsung brand but now the model is already pulled out na sa Ansons. Baka known problem yun. Hindi na daw kasama sa warranty kaya buy-back kahit lugi than suffer the cost of maintaining that crap.

I believe inverter types are less sensitive to power fluctuations based on experience. I live in a place where there are lots of commercial establishments. Duing 6-8 pm, when this establishments power down, i get a reading of 248 volts! The increase in voltage has already toasted my cd player, tube amp and projector but my A/C inverter type never broke down. We also use inverters in our workplace to control the speed of our induction motors. We never had a problem with our motors since then (except for the usual bearing replacement).
Capacitors used as power banks helps lessen the cost of electricity in an industrial set-up because industrial accounts have power factor adjustments. I'm not sure how it helps lessen the cost of electricity in a residential setting.
Hi Nelson, you are correct. The power factor is being corrected by the capacitor bank. Same as industrial type and residential. The capacitor bank is one way of correcting the power factor.
For the inverter type of aircon, that's what the 'technician' told me. I just turned away from that brand for aircon unit. The fone is superb!

Re: Aircon - Are Inverter types worth it?
Time came for me to move to a new house. This gave me an opportunity to test Inverter models as I decided to use one on my new place. In the interest of evaluation I compared my recently purchased LG 2.5 HP window type aircon with an LG 2.5 premium inverter with a claimed 60% savings. The results, considering lighting and other appliance that may have effect in my monthly consumption, was astounding. My average bill to run a conventional model is 7k/ month. With the inverter under the same conditions only reached 4.4k/month. The savings was remarkable and game changing. By the way, the timing of my purchase was just great. I got mine on sale for 39,200 for the 2.5hp premium series. Normal price is 50,500 at most appliance stores. Now if inverters are priced this way then switching types won't be too difficult.
Re: Aircon - Are Inverter types worth it?
it really is a game changer, I got the whole house cooled with this, mine is an LG too, I am totally satisfied with its performance. My electric bill maxed to 3.8K last summer.
Re: Aircon - Are Inverter types worth it?
I can attest to that. I've been using LG inverter aircon too..
Good to hear an inverter works! Except that friggin Samsung type..

Re: Aircon - Are Inverter types worth it?
Yeah, that brand really sucks! I bought their ref last November 2012 and now I shelved it 'coz that #--------! just doesn't work. I've had to report it to the dealer 5x and only got visited once by their service staff and still nothing good came out of it. When i bought my LG inverter the vendor had a Samsung 1HP running on a 12 square meter room and you could feel the useless performance of the product considering the ceiling was just around 2.6m high. It's LG for me, price and performance wise.:)
Re: Aircon - Are Inverter types worth it?
but wait, a bit OT here, I am about to buy a Samsung inverter refregirator. I did not know the actual performance of Samsung AC inverter, I think refregirator and AC are cousins, can anybody comment about Samsung inverter refregirator? I can delay my purchase and research more on this.

Don't waist your money. There are other better brands. I will buy LG or Electrolux to replace my Samsung ref. A bit OT but timely.
Agree with bro willy... Go Electrolux or Panasonic/National or LG.. Support for Panasonic is good.

Sir, did you consider the ambient temperature while you were using the conventional A/C (May & June are summer months) vs ngayon July (kinda umuulan na) when you used your inverter A/C.
