My friend Daikin inverter 2.5hp about age 2 month old, not temperature not as cold as earlier and compressor motor getting loud noise, set temp to 16c but room temp is 20c plus.
outlet air was only get 16c compare to his other 2.5hp panasonic outlet was 10c.

i want to see which air cond you set 16 deg you get 16 deg room temperature lo.
outlet temperature of old AC is only 10deg C?
wow...i can only imagine the relative humidity...sure dry like hell...

Hi guys i have a question, i don't understand why this MHI air cond have 5 star energy saving but its not inverter air cond? Please refer to bellow catalog

http://static1.squarespace.com/static/5574...77/CRS+info.pdf

Depends to this bellow non inverter type this MHI air cond only have 3 star energy saving

http://static1.squarespace.com/static/5574...CR+CRR+info.pdf

Did any one know what is the different of this two air cond?I asked the seller they say the 5 star energy MHI non inverter air cond is normal energy saving air cond abit same like inverter but its not using electric board to control the compressor.....

Any comment for this air cond?
*
You can see the eer rating. For the 5 star, eer is 12.45.
For the 3 star is only 10.8.
This means the 5 star is more efficient. Can see that they used bigger outdoor unit which might help in this.
What's the price of the 5 star unit?

Sharing something here.

Installed a Panasonic 1.5HP Econavi Inverter.

Date installed : 31 Oct 2015
Days of usage: approx 13 Days (remaining days outstation)
Bill cycle: 16.10.2015 - 16.11.2015

AC operates from 8 pm to 3 am every night with temp range 24 - 25 degree Celsius. with the setting set at AUTO for everything and ECONAVI is turned ON.

» Click to show Spoiler - click again to hide... «


My initial observation is the AC did not consumed so much of electricity if you are using the AC to regulate the temperature, not as a machine to cool down the temperature like your refrigerator.

My observation may not be so accurate since I've just installed it and did not run for full month. but looking at the average of my electricity bill.i could say that it is worth it.

Furthermore I also installed Alpha 18i water heater on the very same day with AC, and it is running twice a day in average.
*
your usage almost exactly like mine.
but mine is 1 HP.
now my monthly bill is hovering around RM 45.
i expect yours to be around RM 50 for slightly higher horsepower and water heater!

you are using the same brand with similar settings?

previously my bill was around RM 2x-3x
then i have a kid and started to use AC at night.
baby was sleeping with us in the master bedroom and bill was skyhigh.
then move baby out to own room and installed panasonic 1HP inverter.
setting is 26 deg C without econavi (need to manually turn on, pain in the @$$)
switch on from 8 pm to 3.30 am
then bill went back down to around RM 45. flex.gif

i did asked, my wire man (doing AC installation as well) said inverter not really cost saving, another (AC seller) said inverter PCB very expensive if broken. since i never use inverter model before very hard to justify. 

actually i wanted to get inverter model for rooms (use most) and non-inverter for living and dining.

then i should look for more option.
*
I have a 2HP non inverter in my master bed room.
used daily from 8 pm till 4 am.
Electric bill was around RM 150.

Then i switch to small room with 1 HP inverter
used daily from 8 pm till 4 am.
electric bill is around RM 50.

you decide.

Guess is you that bullshitting. Even the photo you posted also state clearly you are bullshitting. First time I see a contractor telling other that he is not a competent contractor but trying to act like a pro. A sinkalan are more appropriate for you.
The wiring diagram already stated clearly it has a power supply. So the question now is, where this power supply taking from? From the main DB also wrong to begin with. Taking from 1 of the room? Again is wrong.
Unless you are trying to cheat me that blower unit using more power supply, fast fast, go get another troll to support you lies rclxs0.gif
When dealing with multi tenant issue, installing independent air cond are the best way, not with such setup.
Still, your lies will become fact once you get more trolls that able to support your lies that blower unit consume more power whistling.gif

about power consumption for Panasonic Inverter 1.0HP CS-S10SKH,

Cooling Capacity =  9,550 (2,860-11,200) Btu/h  OR  2.80 (0.84-3.28) kW
EER = 12.6 Btu/hW

let say i use 12 hour per day, mean (2.80kw x 12 hour x 0.281 sen/kWh) x 30days = monthly power consumption fee is RM283.25
since i never use A/C before, actually how common an A/C can reach or keeping 9,550 Btu/h in all day, is that necessary?
if not necessary, how i estimate roughly power consumption a day if i try to reduce the Btu/h as low as possible?
i worry to have a surprise for the expensive monthly electric bill,

and about the maintenance, how long it need to be service, can i DIY myself, if can't, how much i need to pay for a service?

notworthy.gif  Thank a lot.
*
For that unit, the power consumption is : 760 (225-920)
what i found for my unit installed in small room ~100 sqft
the power consumption is around 250-300 after reached the pre-set temperature (26 deg C)
so for night time usage of ~8hrs
0.3 x 8 hour x RM 0.334 x 30 days = RM 24 per month.

maintenance, i found the blower gets really dirty..not sure why since the filter is not that dirty
just used a tooth brush to slowly scrub the blower and it's all good thumbup.gif

Any Panasonic air cond expert or CS-S10SKH user here that can guide me on how to permanently turn off nanoe-g ? I tried press n hold the nanoe-g button on the remote until beep sound, but it still activated the next time i power on the air cond.

Also, anybody using the new Panasonic elite sky series ? Any comment ?

Thanks !

have you tried not switching off the double pole switch (the one with the red light)?
the annoying part of panasonic AC is they tend to 'forget' our settings once power is cut to the unit.

U mean the double pole switch at the main DB? No, i never do that.

I dug out the user manual n cannot find anything that can totally turn off the nanoe-g, but found out that press n hold nanoe-g button on remote only can activate/deactivate "in-filter deactivation".
*
You don't need to press and hold to off the nanoe-g
Just press it once on the remote and the blue light should turn off.

Just use the remote to on/off the air cond. the nanoe-g should remain off the next time you turn it on.

I tried that, I switch off the air cond while nanoe-g is off (blue light off), the next time i on the air cond, the nanoe-g will be on too.

But i turn off the power socket too after switched off the air cond.
*
that's the thing, if you dont switch off at the power socket then it'll remember your last settings.
once you off, it'll "forget".

what's are the probably causes where at night aircond set at 25 used to be just enough cold and comfortable for sleeping, but recently 25C become warm and i have to lowered to 24C to get the same environment as previously?

I have washed the mesh filter, air cond age 1 year+, only on at night 11pm++ till 6am ++ a day
*
how often you do the filter cleaning?
i found that filter cleaning alone is not quite enough.
the blower needs to be cleaned as well...
i didnt open up the casing, just used a tooth brush to brush off the dust.
it helps a lot.

might consider to get those pressure spray bottle to clean the coil as well.

Hi need opinion here.

My room 23 feet length x 7f width x 7f height ( with morning and afternoon sun till about 4.30pm

My old non inverter air cond 1.5hp
My controller  set to 20 celcius ,  But my room temperature maintain at about 25 celcius +\-  ( even on for 12 hours also 25 degree +\-)

My question : Is that mean my aircond is undersize because room temperature couldn't meet 20 celcius?
I learned from article saying over or undersize my aircond will still burn my wallet. Need advice tq.

I attach pictures as below

brother, fan speed no.1 how to get 20 deg C?
set it to full speed and test again?

nice info.
But think your calculation needs to be updated.
need to consider 1 hour full load, then 2 hours 50% load and remaining 3hours at minimum load.
that should give better representation.

should give the excel so we are sort thumbsup.gif

Great feedback you have there, will provide the excel spreadsheet later.
Please provide a guideline on the % of load versus time if you have.
Something like this should be useful, example:
1st hour: 100%
2nd hour: 50%
3rd hour: 20%
4th hour and onwards: 30%
*
For my small room application, i notice that the compressor will run full load at start till around 30 minutes later when it start to slow down.
For ease of calculation, just assume full load for 1 hour.
Then just to make it more severe, just assume 50% load for next 2 hours.
from panasonic website you can see the min and max power consumption, just average it out?
Then assume minimum load for the next 3 hours (assuming room has reached set temperature and outside temperature around 1-2 am is cool-ish)
For non inverter, i am not sure how to calculate this.
Maybe use 10-20% of the full load?

This should give a good advantage to the inverter.
because i notice my inverter air cond paid for itself in 1 year thumbup.gif

The aircond working load is depends on many aspects of things, like room size, window facing, air leak, appliances in room, number of people in room, heat insulation in room, desired temperature set, outside temperature, outdoor unit ventilation, and etc..
Therefore it is quite hard to estimate the aircond working load.

Load calculation for inverter and non-inverter aircond should have difference, since inverter aircond can control the compressor motor speed, versus non-inverter aircond just turn on and off the compressor. Some inverter aircond have smart functions that can detect the present of human being, and control the compressor to further optimize power consumption.

I do agree with you that, to simplify the calculation, can put full load at first hour, then certain percentage of full load at next hour and etc.

Best way to estimate is to monitor your aircond behavior for load and then come out with your own estimate for that room. For those people who does not have existing aircond, have to perform rough calculation.
*
That's why i suggest to put assumption on the part loading.
Because based on your full load calculation, the high efficiency models (>13 BTU/w) can never be justified to be purchased!

Please advise on my aircond sizing plan

1) GF Hall - 2.0 Hp (5m x 5.6m)

2) GF Study Room - 1.5 Hp (4.2m x 3.1m)
1.0 HP is sufficient

3) FF Guest Room - 1.5 Hp (4.9m x 3.8m)

4) FF Family Hall - 3.0 Hp Ceiling Cassette
2.0~2.5 HP is sufficient

5) FF Dining - 3.0 Hp Ceiling Cassette
2.0~2.5 HP is sufficient

6) SF Masterbedroom Wardrobe - 1.5 Hp (3.8m x 3.8m)
1.0 HP is sufficient

7) SF Masterbedroom - 2.5 Hp (6m x 5.6m)

8) SF Prayer Room - 1.5 Hp (4.2m x 3.1m)
1 HP is sufficient

9) SF Bedroom Small - 1.5 Hp (3.7m x 4.2m)
1 HP may be sufficient if mostly use at night

10 SF Bedroom Big - 2.0 Hp (5.1m x 3.8m)
1.5 HP is sufficient

For first floor (~4m x ~15m), the family hall, dining and dry kitchen will share two 3 Hp Ceiling type aircond (item 4 & item 5).

Floor height is roughly 10'. Please advise on my sizing selection.  icon_question.gif
