Panasonic Inverster System 2 Installed

Previous LG usage: 16 - 20kW every night
Current usage: 5-7kW every night

Expected savings: 60% electric bill! Woohoo!!!

there is some user using Panasonic inverter system 1 here before.. and her review is quite good..

I agree non-inverter sucks big time... so I will be posting a review for Panasonic Inverter SYstem 2 here.

Installation Date: 4 December 2010

May I know what type of house you live in ? I notice that most of your bedroom area is very big and all bigger than 110m2.
Your bedroom area already bigger than my hdb flat leh.
Really elite.
elite where got stay in HDB??? mine is the older type of 5 room HDB. Older HDB are slightly bigger than current ones.. Best is the masterbed room toilet is built out of the room, not inside the room, thus making the room bigger.

Hi..

Use the option 3, since you wont use the living room often.
This config, you have 30,000 BTU.. room aircon is capable of running 8500 BTU when Living room is not turned on... while living room is 16,000 BTU.

This option is good enough... 9000 BTU aircon is capable to cool down 20sqm room


need some advice from people here.

Been using a roughly 10 years old Mc quay (who uses mc quay air con!!!!????) from previous house owner.Planning to install a system 4 in my unit. 3 bedrooms and 1 living room. i think the living one will be seldom used so priority will go to the bedrooms and also will add a sliding door to the kitchen to prevent the cool air from entering. Attached is my floor plan. not sure are they in meter or feet? anyway was looking at these mitsubishi inverter models. Any advice which package should i choose? will the below choices be underpowered? Btw, current pipings is installed and hidden inside false ceiling, if i am to install the new one, will the installers help to hide the new pipings inside the false ceilings or install under the false ceilings? any help will be great!!!

1) Mitsubishi Electric
MXY-4A28VA / 3 X MSY-GE10VA / MSY-GE24VA
4,742 x 3 Btu/hr + 11,361 Btu/hr

2) Mitsubishi Electric
MXY-4A28VA / 3 X MSY-GE10VA / MSY-GE26VA
4,367 x 3 Btu/hr + 12,487 Btu/hr

3) Mitsubishi Electric
MXY-4A28VA / 3 X MSY-GE10VA / MSY-GE18VA
5,118 x 3 Btu/hr + 10,236 Btu/hr

I prefer R22 due to cheaper cost.
R410 maybe in 5 years time.

http://www.daikin.com.sg/svc_charges.asp

example of daikin charging
R22 $10
R410A $35

for the environment, are you willing to pay the extra $25?
how often do we need to refill the refrigerant? if there no leakage, dont think we ever need to refill the refrigerant.
and R410A units are more efficient than the R22. only down point for R410A i see till now is the higher cost.

For my current all using R410a do not worry about installation leakage you need to paid.
It is all to be Aircon contractor to be paid for it because install not propery.
After used for 5 years later u still don't worry have to refill gas, no such thing to have refill it is only contractor need to charge you more for service cost.
For my previous model R22 already using 7 years still keep well cooling without any refill from new install.
Only you may hardworking to wash your air filter by often in every 2-3 months it is also depend your environment have more dust or no main road at your unit so won't be worry it at future.
Can give 1000 heart for use with R410a gas.

New model will use R410A... so in the long run R22 may be more expensive (coz lesser production).

I have a 3yr old Daikin single spilt inverter unit in my second floor bedroom, its a 3-tick rating unit which runs on R22.

Is the condenser fan in an inverter system supposed to run continuously? I notice the fan runs for about 15mins, stops for a couple and then runs again.

Is this normal?

The newly installed Toshiba inverter unit for the hall seems to run different, the fan is always running.

inverter will also will stop running one when temp is reached wit its slowest setting.

but i guess becos yr old inverter is a 3-tick, now inverter is like 4-tick.

Your daikin Aircon if from start switch on to runs at 15min outside condenser fan is top and runs again.

Couldn't be so fast to reached the temperature if for whole day is hot weather.
For inside room temperature didn't suddenly change to be too warm just like blow out the fan that is fine.

I guess your Aircon has some error to be check it out.

If your room is still cold and your setting is 24-26. Then the fan stopping is normal.

Yap sure is true, stopping when the temperature are reached.
But not to apply from starting switch on and quicky cooling down and stopping for while just for 15 min. Only.
Especially using R22 gas. Only raining day or room size very small.
If the Aircon is using non-inverter I will suggest you turn on normal stand fan.
Ha ha
Ya inverter Aircon fan motor will be go slowly or stopping, that is due to a long hours before from operates.
So if not normal working just call to service and ask.

My panasonic non-inverter system 3 aircon which i only on for masterbedroom everynight. I set the temp to 23 cool mode medium fan speed and i realize that when it cut off then another 5 mins later it will cut in again. Then after on for another 5 mins or so it cut off again & the procedure go on & on? I was wondering if it is normal to work this way? Also during the cut off it is like the whole room quite stuffy & hot.
