The nanoe-X technology from Panasonic is much superior than the others. For that reason, luxury car Lexus and Camry are using nanoe-X inside their cars.

Google it. There is science behind this ingenuity developed by the Japanese with plenty of lab testing to prove its effectiveness.

bro... this nanoeX is not rocket science . its just marketing gimmmik
its only positive and negative ions .

SHARP have this many year ago . Plasmacluster
I would say the Sharp was the first to use it in AC s

China Midea , Gree also have this too


the problem with pana is they charge you BIG buck nod.gif

From above

Living + Dining -  2HP

Bedroom 1, 2 and 3 - 1HP

am i correct?
*
yes..
but i will put a 1.5hp in BR 1.

underdimension with cause the AC work more so you lose some power savings .

Is it the new midea forest models? Looking for 1hp and 2hp for small and living room. Seems nice got ionizer but cheaper
*
yes.. midea forest thumbsup.gif
a good value buy .


I work in a company doing operation and maintenance of telecom networks and have first hand knowledge
of huawei, zte , ericsson , nokia systems. switching network, power systems, microwave , fiber systems , billing systems.
we keep data of all maintenance fault in the mobile operator means i know what part fails the most and who has the most
reliable pcb s .

you can buy the top 3 china Airconds without worry .
i put their reliability / failure rate equal to Pana and Daikin.

just take a look at haier ,,, I see they give compressor warranty 10 YEARS and general waranty 3 years . what does that mean .
they know that failure rate will be small.

on the plus side for pana and diakin ..they have better power savings .

but bedroom 1 calculation

140.47 x 60 = 8,428.2 nearly to 10000  that is 1 HP but why 1.5 HP still cannot understand smile.gif
*
gut feeling with experience.

it can be from 1 to 1.5hp
its getting hotter every year nod.gif
and a bigger size AC , you put it under less stress.

many have complain about AC failures but we dont know about the User .
can be the AC was too small size
maybe user sets his remote temp very low ...like 20 deg .
maybe user never check filter s status and do regular service .
some users run the AC for 15 hours contineous regulary .
result is premature failure of the AC .s

Thanks for the info and good fact, haier is abit uncommon hence why i erase from the list. But very surprising and sketchy when they offered that lol. Was thinking if wana go sharp for all the rooms. But i just got the plasmacluster for master first. And surveyed on lazada and shopee. Seems like bang for bucks on midea and reading around like why so less ppl using midea haha but i guess I'll give it a go
*
yes midea , gree , hisense all OK . need to filter out what you want.

they have feature s with ionizer /plasma and iFeel /follow me.
the feature Follow me is great . you can control and get the right temp at a local spot as your remote have a temp sensor.

still many people dont trust china product ... so they hesistate .

I guess those manufacturer realized that making durable thing is not the right way to do business. Durable=less sales over time sweat.gif
*
so for Aircond ...most of the electronic components can last around 10 years if put on NORMAL use.
components degrade over time .

Airconds Performance usually degrade over time . with loss of cooling and higher power consumption . like 5 to 10%
so I feel after 7 years regular use , time to start looking for a NEW one .. wait for better offers during Sales. . thumbsup.gif

so why use a 10 years aircond when you pay more for power and less cooling. do a ROI will help .

Hello sifus. Im planning to get an aircond. Room is very small so a 1hp ac will be more than enuf.

My plan is to install a new ac next week. Im planning of buying an inverter daikin ac since i plan on buying a new unit, I plan to be using it as long as it lasts.

Now my question is, should i buy inverter or non inverter? Im usually working most of the time and is only home past 6 or 7pm everyday. I doubt my usage will last longer than 5 hours everyday and i dont use the aircond if the weather is not unbearably hot.

On weekends, i might be lazing off thus i will use the aircond maybe more than 8 hours while i game on my pc.

So, should i get inverter or non inverter? Will my bill be very different or just negligible?

Anyone who owns 1hp ac that uses their ac more than 8hours everyday here? How much is your electrical bill?
Lets say if i use my ac 5 hours everyday, how much will my bill be?
*
Assuming you use the AC 1hp for 6 hours contineous a day . Night time , temp set to 25 deg, 30 sen perKwh .

invertor AC will cost you about 1rm a day .
non invertor will cost you about 2 rm a day.

Hi sifus, i am comparing Midea and Sharp 1HP R32 inverter aircond.
Sharp: BTU=9700, power=890w, 5 stars rating
Midea: BTU=10000, power=755w, 4 stars rating

Can i say Sharp one is more energy saving?
*
your figures seem something not right nod.gif

use EER , check the AC spec for this value. the higher the more powersaving.

How is EER calculated?
The air conditioner EER is its British thermal units (BTU) rating over its wattage. For example, if a 10,000-BTU air conditioner consumes 1,200 watts, its rating is 8.3 (10,000 BTU/1,200 watts). The higher the rating is, the more efficient the air conditioning unit is. However, a higher rating is usually accompanied by a higher price.



from shopee
Power Supply (V-Hz-Ph) 220-240V~ ,50Hz, 1Ph
Cooling Capacity (Btu/h) 9500
Power Consumption (W) 880
Running Current (A) 3.8
Weighted EER (Btu/h/w) 10.45
Energy Efficiency Star Rating 3

Sorry, i forget to put the links in my earlier post.

Sharp: https://my.sharp/products/air-care/ahx9ved2?v=1149
Midea: https://www.lazada.com.my/products/midea-10...i768154307.html

Sharp EER=9700/890=10.9 (website put 5 stars rating)
Midea EER=10000/755=13.25 (picture shows 4 stars rating)

My calculation is correct right? I am confuse why Sharp one higher stars rating.
*
i guess with Midea you cannot use those figures.

Midea spec only state CSPF figure
Sharp give EER figure .

Malaysia use CSPF to give the Stars .rating.

5.0 Star Rating
The star rating shall be in accordance with Tables 1
Table 1 :
The rated cooling capacity < 4.5kW
Star Rating Tested CSPF (Wh/Wh)
5 ≥5.30
4 4.60 ≤CSPF<5.30
3 3.30 ≤ CSPF<4.60
2 3.10 ≤ CSPF<3.30
1 <3.10

bro how about this two pictures below?


Which one is better?

*
base on CSPF 5.63 vs 5.34
I will say AC 1 more powersaving . nod.gif

if base on EER than unit 2 is more powersaving .

this is due to the method of test measurement . by the way malaysia use CSPF . check the ST documents.

EER test done at 35deg C only .
hence cannot tell the effiency over all operating temp range .

CSPF value is the average over all operating temp .

google CSPF vs EER you will undertand more.

As for the AC s in question the powersaving difference is very small like 4 % .

Just replying because momo dishing out all the good infos

As i myself have repetitively checked on AC also. Probably gona change to inverter for living room too as in the long run spend more time there. Dunno roi worth it or not as half the month im not around
*
get one like pana invertor if budget permits.

life of AC also depends on total usage time ...so if you not around no worries...

The calculated one by developer is 18500 btu approx. So looking for 2HP also. Just not sure how calculations are viable nowadays since. The temp now and the temp 10 years back are different haha
Was leaning on budgeted midea. Because i have the plasmacluster in master. As id be more time there obviously. Just browsing through more pages whether i need inv or not for living haha. But from calculations and EER mcm not worth it. Only time would be if got gathering etc. Otherwise im pretty good with windows open wind
*
budget midea is fine but get the invertor type
2hp non invertor suck s power . . 6 hours contineous use will cost you approx 6 rm .

guys.. how frequent do i need to service my aircond for non heavy user like me? i always used dry mode at 25 Celsius all the time and only turn it on when its really hot for few hours per day. Do I need to service it when the coolness start to deteriorate?
*
I dont understand why you run DRY mode all the time , care to explain hmm.gif

yes.... if you feel coolness deteriorate and check the filters and coils for dust every 3 months or less if that area is dusty .

OK ...

when you remove the sensor can use a multimeter to measure the resistance..

then put sensor head in cold ice water and see the resistance will change .

end up he say PCB spoilt, took back repair call me say RM400... wan or not... no choice pay...

Notice maybe change a few capacitor looked like thing... probably ken parang 99..

wow 400 rm doh.gif

what brand Aircond , is it invertor ? is this indoor or outdoor unit pcb ?
if non invertor , new pcb also probably less than 250 rm .

on the pcb are smaller caps probably cost 5 rm each .
you change all caps yourself also less than 50rm .
