Asking all sifu's out there.
Im looking for an energy saving 1.0 HP - AC ( Inverter ) for a 13x13 feet bedroom. I've read many pages from this thread & want to ask for ADVICE between these A/C's. I have listed some pro and cons of each AC. Feel free to add or comment.
My budget is around 1.6k for the AC.
1- Panasonic CS-S10SKH- RM 1500
The Good-Panasonic is energy efficient ( 5stars - 1492kw/h) compared to other models. Has alot of functions.
The Bad- Service i heard is bad. Parts e.g (PCB) board are expensive to replace.
2- Daikin FTK10T inverter - RM 1450
The Good-Reviews about Daikin Ac in general is quite good ( Service & Parts). DC inverter, not sure what other brands are using but daikin highly promotes the DC inverter over AC inverter.
But does anyone have experience with this particular model before? The energy ratings ( Suruhanjaya Tenaga) is not displayed in the showroom or the website. (http://www.daikin.com.my/wall-mounted-series-1-0-2-5hp/) However the brochure does say that it's EER is 12.18.
The Bad - According to one AC service guy he said this AC is not as cold as Panasonic within the same temperature range. True???
3-Mitsubishi Inverter Series (http://www.trio-mhiac.com/products) - RM 1600++
The Good- 7 years compressor warranty , 2 years parts warranty. In the website it gives 5 star rating ( Around 1400 kwh ) EER of 12.XX .
The Bad - Heard that the cooling is not so fast(true?). Any comments on their service ?
4-Sharp Inverter J-tech - RM 1600++
The Good- 5 star energy rating ( around 1600++kwh ) . Sharp brand in general has good reviews about their longevity & reliability. Cools fast .
The Bad - Not sure about their service & parts cost.
Please advise.
Basically I won't bother on how many stars an appliance has. Even if it has 10 stars
As those test method won't be same as your usage patterns.
Why I say like this? As I don't know under what type of room use, sun facing direction toward the wall, set temperature, type of paint used on the walls, type of bricks used, curtain used.
I have 2 rooms currently, 1 is facing North, 1 is facing South. Now sun is shinning North while 3 months back more on South. Now my room needs 6 hours to really cool down the whole room to 25°C from 30°C.
Say I'm using the 1HP inverter you mentioned, it requires 920W, so 6*920 = 5520W or 5.5 units used to cool my room down. Considering inverter has higher efficiency on cooling, so I may need 5.5 hours, so 5060W or 5 units.
Then it will go down ramp down state, will it go down to 225W? Sure, if you set it right, else it will still taking > 300W
If I'm using non inverter type, 6*830 = 4980W or 4.9 units to cool my room down.
Basically, for my usage pattern of using air cond and ceiling fan, my ramp down state is air cond off(by timer) and ceiling fan that only using 50-80W. With difference of < 1 unit of difference, inverter air cond does not fit my bill.
