Sure Mit, I'm using MS-FC13VC, 1.5 HP, Deluxe model. Btu 13,307, air flow 10.5. Very high air flow and cool for my room.

B4 this use Panasonic 1.5hp, very bad, need to service very frequent, I year atleast 2 times. Blower not enough power to spin once dust on it, air flow good after service but not lasting, once got a bit dust on it, it will become small air flow. Then change to Mit MS-FC13VC after used 1 year.

My house got Mit, Sharp, York, Acson, National, panasonic, Hitachi, one unit Mit is around 10 years already but still very cool but old Mr Slim model air flow very small but very quite. Sharp used 5 years then blower motor not working.

York and Pana totally out. My York already 6 years already, now not cool and very noisy.

After survey and compare all the air cond, Mit is the best but must buy the deluxe model and with easy clean.

AFAIK, there are Mitsubishi Heavy Industry and Mitsubishi Electric. Different company so which one you are talking about?

Can't believe this thread lasted 3 pages here ...  tongue.gif

Anyway, WTH, my contribution:-

1)  Inverters - Dun read too much into this.  Its 50% marketing talk, some tell me even more.  To actually achieve these savings, the settings of the A/C has to be 'optimum', usually too optimum for our normal usage.  Maybe it gets better for 2kuda and above.
You are wrong. It's not marketing talk. Just technically ignorant.

The truth is, Invertor air condition really does save money ONLY IF you know how to use it. It must be used in a situation whereby there are lots of 'stop-start' operation. Example, a powerful-enough aircond used in the bedroom whereby there are lots of stop-start going on. A Invetor air cond's compressor NEVER actually stop when the room are cold enough nor having to restart when the room are too hot. By preventing 'stop-start' operation, it save electricity. It's the same principle as car using more petrol when there are lots of stop and start operation aka town driving and less when on highway driving.

Used wrongly, it actually uses 10% more electricity and that's why you must never use it in an over-sized room.

I also wonder do Mitsubishi Heavy Industry sells home air-con?
How powerful-enough aircond are you talking about and how much savings in units of Kwh are we expected to see?

Yes, Mitsubishi Heavy Industry does have air cond http://www.mhi.co.jp/en/products/detail/sek-zgx_series.html

And so does Mitsubishi Electric http://global.mitsubishielectric.com/produ...ndex.html#air06


A 9000 BTU in a 20x20 feet room with window open during day time is not considered powerful enough. No stop-start occurring. Since compressor running non-stop, an Invertor air conditioner will actually uses 10% more electricity than a non-Invertor.

A 9000 BTU in a 12x12 feet room with windows all closed at cool night time is considered powerful enough. Plenty of stop-start occurring. In this case, an Invertor will save more electricity than a non-Invertor. Figures of 20 or 40% have been quoted. How much saving will depend on how often there are stop-start operation. More stop-start, more saving. Less stop-start, less saving.

i did ALOT of research before settling on a panasonic...

costs a bit more than york but the "quiet" mode and the "ion" feature was a definite plus smile.gif

Did you looked at Daikin?

From what i know about inverter that the compressor always started at a low speed rotation and the current consumption start at 1.2A and starting to rise until 4.2 A and stop as the room already cold enough.

Once the temp rises , the compressor kick in again but also at 1.2A all over again.

Standard air con started at 4.2 A from the beggining, hence the higher power consumption..

Thanks

This is not my understanding of how an Invertor compressor works. They never stop entirely, just reduced speed/compression/consumption so nothing to 'kick in'. By not having to stop and then 'kick in' from standstill is the key to their lower electrical consumption.

Normal Inverter need different and more expensive piping. So I am leaning toward the Daikin Inverter because it uses the same piping as normal non-Inverter air cond to save cost.

A friend who have both Panasonic and Daikin told me Daikin are super quiet in comparison.
