Window type aircon (inverter)

[shadow]

Hinde ako naniniwala mas matipid inverter na naka on 24hrs panloloko lang yan ng Meralco.

Ganito na lang siguro...

If the claims of 30% savings by inverters over conventional have been established, then 17 hours operation of conventional = 24 hours for inverter. So if you operate your conventional below 17 hours, tama ka, kalokohan lang na mas matipid ang inverter if you operate it 24 hours.

Question....

Window A/C namin is from Panasonic (non-inverter) which on paper consumes 839W (EER Rating of 11.3 kJ/hW)

A Hitachi inverter consumes 849W (EER Rating of 12.7kj/hw)

Significant ba talaga savings if I change to an inverter?

yup. tama explanation ni papi smith. just recently lang din kami nag palit ng inverter AC. although yung monthly consumption namin eh halos same pa din, 412 kWh pero yung gamit namin ng non-inverter AC nuon eh 3-4 hrs/day lang compared sa 10-12 hrs/day ng inverter.

Yes, ung start up ang malakas, kasi pag non inverter, patay sindi ang compressor, so everytime mag on ito, start up phase ulit. Sa inverter pag nakuha na ang temp slow down lang sya, so 1 start up lang. Ang hindi ko lang alam ay paano i-quantify ito, like say 1 start up is equivalent to how many minutes na naka slowdown.

Ung narinig mo, I think galing yan kay Isko, na matipid daw pag 24 hours, pero di naman nya quinalify.

[ninjababez]

hmmm...
malakas kami aircon.
magkano na ba 2 or 2.5 hp inverter...?

... the savings alone, can pay for the new inverter inside of a year...

2x nako "nakalibre" ng ac dahil sa pag switch to inverter

I think of a non-inverter A/C as para kang nagda-drive ng M/T pero parati ka lang naka-primera and an inverter A/C as CVT na continuously ina-adjust ang gear ratio according sa load.

yup. but on paper... the EER and Wattage difference is very low

Check the EER of other models such as Panasonic inverter.
There is a certain model ng Hitachi na marketed as inverter but actual operation is parang non-inverter.
I think HSV model yun which is the one you are referring to.
Compare it to Hitachi HVQ or HV model instead.

This is from tipidpc thread about that model:

10. Hitachi RA-10HSV <click here for link> Hitachi intends to further solidify their hold on the compact segment by releasing the cheaper HSV variant. It is another single fan unit to cut costs, and even has 0.60HP and 0.75HP capacities for tiny rooms. But please AVOID AT ALL COSTS as not only it is susceptible to the front panel PCB failing prematurely, it operates like a conventional aircon resulting in high electric bills! Watch this video if you don't believe me! <click here for link>
EER (KJ/HW) - 11.9
Refrigerant – R410a
Size (WxHxD) - 470 x 340 x 600

Yes, ROI for cost difference is about 18 months or so ... assuming you set temperature between 22C and 25C ... minimum use around 8-10 hours per day ... less than that, minimal savings but can still recoup within 3 years or so ...

Oh, for rarely used air conditioners, just buy the basic with manual switch ... an insect will eventually fry your electronics ...

Avoid running air conditioner 24 hours ... if you must, then room must have 2 units to alternate usage ...

but why?
aircons aren't living things that need rest...

Sa US, mga relatives namin walang patayan ng AC, ung bro in law ko pag umuwi ng Pinas hindi pinapatay ang AC para daw hindi magkaron ng molds.

Curious rin ako bakit.. may AC ako sa bahay wala patayan madalas months pa inaabot. pinapatay lang kapag nililinis ko or kapag wala talaga tao sa bahay.

isip ko parehas lang ito ng mga ref eh, and difference lang eh controlled yung box ng ref vs a room na maraming lusutan.

[Walter]

Refrigerators actually shut down when set temperature is achieved ... most aircons have their fans still running even when compressor turns off ... they'll just last longer if not run 24 hours most of the time ... but, hey, if one has the budget then by all means it's ok ...

Interesting thing about the molds ... have air conditioners that run once a week or once a month ... have not experienced mold issues ...

[papi smith]

Not that interesting bro, it only means that there is a source of moisture that encourage mold growth and the drying effect of the AC helps in preventing it. Seems you are more concerned about the fan motor rather than the compressor giving out. Anyway, ang hindi ko lang inalam ay kung gaano sila katagal.mag palit ng AC unit.

when we were kids, our use of the aircon was dictated from above.
"ten hours lang ang aircon. 8 pm to 6 am. and absolutely no aircon in the daytime."
yes, the aircon did last several years, but we weren't too happy with its limited use.

i suspect,
the limited use of aircon was to save on electricity... increased aircon longevity was a happenstance secondary effect.
heh heh.

Just an update. Ansons offered a Panasonic Conventional ac that has 11.3 eer, surprisingly, it fits the hole and no need for minor works. Ended up buying that instead of the Condura and it's also cheaper. So far, wife's happy with the cooling cap of Panasonic. Hopefully the higher eer (close to inverter eer's) translates to tiny savings the least.

Thanks for the insights, guys. Will probably try the inverter ac soon, when replacing the old one on my parent's house.

not sure why you're expecting same kwh consumptions because of relatively close EERs....

here's 1.5t non inverter and a 1.5T inverter with almost same EERs.... look at the consumption (kWH)...

marami talaga naloloko ng cheaper "non inverter"

[_Qwerty_]

mura talaga ang non inverter aircon ngayon.. halos bagsak presyo na nga kasi wala na masyado bumibili...

a regular non inverter 1 HP aircon consumes around 600WH/1000.. so that's .6KwH (let's say 10 pesos per hour Meralco) so that's 6 pesos per hour x 8 per day or around 48 pesos per day x 30 days = 1440 a month consumption x 12 = 17,280 per year.

our lg dual inverter 1 HP consumes around 275KWH/1000.. .275KwH x 10 pesos = 2.75 per hour x 8 = 22 pesos x 30 days = 660 pesos a month x 12 = 7,920 per year.

Magkano na kaya ang price difference ngayon? Kuha na ba ito in 1 year? Dati kasi kwenta ko 3 years dahil 30% savings, ung compute mo halos kalahati e

Saan makita yun consumption ng inverter na AC?
