Non inverter: 100% and 0% only
Inverter: 100%,90%...0% or so

If you really want to measure the cost, get the kwh(kilowatthour) for one whole day for several days because there are so many parameters that affect power consumption.

How to share on part load?

Daily turn on from 9pm till 1-2am around that time can realise the compressor runing in low speed or stopping too or even gas cut off too..

Actually on non-inverter was the same, just on & off compressor for non-stop till next day, but the current input watts never reduce at all.

That's the reason from inverter can doing more well to hander after reaching on pre-set of temp set from.

The most important factor is to ensure all cable connection are tighten properly.
Then follow by turn off appliance(not on s/by mode) when not in use.

the main thing is, non-inverter has a fixed EER
for inverter, the EER is actually better (higher) at low load conditions
so when pre-set temperature is reached, the inverter can be very efficient compared to non-inverter

Initial i plan to try other brand , now due to budget and stability , i opt only Pana and Daikin first.

silly question here.

Can i install 2 indoor unit connecting to 1 outdoor unit. Let say i install 2HP outdoor unit and for indoor unit i will place it in my living room and the other at my master bedroom.

During the day i use living room, at night i use the bedroom. Is it possible?

Sure just look at Daikin GA for super multi split unit, even 3 to 4 units also can, just look at the model unit only

Hello guys my house come with concealed piping. I would like to know if it possible to use R32 gas air-conditioner with the current copper piping as heard that R401 gas air-conditioner do not support concealed copper piping.Thank

R410a still acceptable for most conceal walls.

Not so sure the G23 = 0.6mm able to used with R32 or not, might be G22 0.65mm at least can able to support for R32 more higher pressure than R410a

Anyway just ask ur Aircon guy to check before and conform to buy which type of gas aircon

Rather than asking such question, why not do the pipe thickness measurement first?

Can, but the efficiency will be much lower.
Installing air cond both of the units should be as near as possible.

hi, sifu here

I had installed brand new air cond. two month ago.
But these few weeks i noticed rusty water droplets on the bottom my outdoor unit.

Do you guys have any idea on what it the root cause ? or any had experienced it before ? bad installation ?

Call the shop where you bought it.

Rust is due to cheap mfg lag bro..

Galvanized steel where got so fast getting rusting, go do more OT

hmm. what is OT ?

I going to call the installer guy. Hoping here can have some opinion on the cause. dun want later the installer guy cincai give reason.

Meant do more research

Usually like steel base with painted coating would be getting rust is very common lah..

Unless the base is comes with galvanized steel then can be last for at least 5 yrs

My ME even galvanized steel when usage every also cause by rusting, but over 6 yrs from now

manufacturer's fault , didnt coat thick enough epoxy powder .

Look like pana but not sure which brand

well, i just called the air cond installer. he told me to deal with the manufacturer of the air cond.
guess, i have to deal with the shop sales person to whom i buy as suggested by @supersound
At first, i thought the reason will be the outdoor unit installation process.

FYI of this thread, its a hitachi 2.5HP.

Another unit is 1.0 HP Hitachi. later i going to check on this another outdoor unit whether have the same problem or not.
