Inverter Type AC in Pakistan (Inverter/Non Inverter Dedicated Discussion)

[krafiq]

Size of AC? Size of room? Ambient temperature and is the room exposed to sunlight?
Generally 1.5 ton goes upto 9 Amps then settles down to 2.9.
These numbers depend on the ambient temperature though. In summers when outside temp is high 2.5-2.9 is resting amp, when weather is fine goes down to 2.0 amps.
Also depends on the brand, Acson for instance hits even lower amps faster.

Can we charge r32 instead of 410.......
Purpose is to enhance better efficiency of the system.......
Secondly is oil charged in these ac when gas is charged??
When gas is leaked..... Oil will also leak or not

Ijaz 03125191054 for RWP and ISB.
Charged me 4k for installation with vacuum pump.

Room is 18 by 15. Inverter 1.5 ton. 1 wall and roof is exposed to sun. Temperature 35 . AC temperature set on 27.
Amperes are always above 4.

Last night, for 10 hours usage, my 1.5 ton tcl miracle consumed only 5 units.

Set at 24c.

This is 0.5 units per hour..

Sounds super cheap.. not sure if reliable readings as done via Brii

Check your manual and remote if your ac has got sleep mode. If it got, use that and it will be more economical and comfortable. In gree, sleep mode is there and once I tried it now I am using it on daily basis and room remains very comfortable ma sha Allah

[mgalaxy3]

Yep sleep mode is there. Will try it.

How many units your Gree consumes? Night vs day

[dms664]

Not calculated it. Will do it in this month, in sha Allah
I am looking for a good amp meter these days. Could you be kind to recommend me one good amp meter?

[mgalaxy3]

Rather than Amp meter I'd suggest a power/energy meter.

One is Brii power meter, available on . If your ac socket isn't too high up on the wall and almost level or below your eye, then it's good and easy to read.

There is also a wifi power switch/meter, sonoff pow 2, but its a hassle to install. Have to cut the wiring to install it.

Thanks
Please share daraz link from where you ordered.

Thanks

Sounds like 4 amps is on higher side. Should be lower in my experience. Possible reasons
1. Your room size is 270 sq feet. 1.5 ton is stretched to it's limit. As per video posted above 1.5 ton max out at 250 sq feet.post no 7198.
2. What about your out door? Is it under shade or exposed to direct sunlight? Is it in well ventilated place? Try adding a shade over it if it's exposed.
3. General tip. Keep the door and window well insulated so draft doesn't escape from the bottom of door. You can use door sealers that are easily available online.
4. When was it last serviced? Outdoor and indoor both? Filters are clean? Servicing and cleaning of dust also helps in reducing amps

[dms664]

My old general split is still in competition ma sha Allah though it is very heavy on pocket . It outdoor sounds exactly like a window ac

last season, i tried to clean the blower via spraying soapy water to it, but water was dripping from under the AC unit, so i stopped. i will try to remove the cover and will clean the coil with spraying soapy water mixed with vinegar. lets see how it drains out. while regarding blower, it gets dirty way too quickly and its hard to reach and clean. saw a video, where he was removing the blower but i won't risk diy for now.

[zeus65]

well, it seems one should do check the vent temps to gauge the ac performance.
i yesterday tried to see vent temps via same device. but it stuck around 13 degrees. i will try to measure at different times and then will conclude.
so, what else did you or the tech check for higher vent temps??
you said that it was this vent temp variation btw 2 of your ACs got you the replacement. so what else to check to confirm the low performance?

[ch.talal]

Vent temperature doesn't tell the whole story. So ignore that if it is cooling the room good.

It's reliable. Brii meters are perfectly synchronised.

Why are you running at 24? Run it at 26 for further savings.

[dms664]

beside vent temperature it was also not cooling the room. like u say that feeling of AC running in the room. it was absent.
to check vent temperature, check it when the room is hot and ac has started a while ago trying to achieve the temperature. set the temperature on ac to 16 so that ac runs on full blast. with that ur vent temperature should be 10 or below that.

Nope. Don't do it. R32 requires bigger condenser so you would end up with poor cooling and may cause thermal tripping of compressor.

Charging oil is not required.

Set fan speed to low to correctly measure vent temperature. Make sure you have an ampere or watt meter installed to keep eye on power being drawn. It should be peaking to get correct reading.

Besides if it is not cooling well then gas pressure might be low or other issue.
