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

[umans]

Thats the dilemma here, even manufactures are not following correct procedures. You have to take pain of your equipment, don't install without vacuuming lines. If you are in Lahore you can easily find installers with vacuum pump.

I have read a lot of guys are saying the Inverter AC stats getting lower Ampare once the desired temp is achieved which is incorrect.

Inverters produced for instant cooling and massive saving but due to misconception people keeps on saying the Inverter will start saving after achehiving the required Temp.

The fact is, Once you start your ac it will sense the temp difference between room and outside temp which the outdoor unit is installed.

If you set temp 26 and out side temp is not very hot then the inverter ac will sense that it is not supposed to work harder to obtain desired temp thus it will work slowly therefore it will consum lower Ampares.

Incase you set the temp 16/17 and outside temp is 40 plus the inverter ac will sense it needs to do a lot to achehive desired temp thus it will work on full throttle to obtain 16/17 temp which it cant obtain so it will keep running on full power and will consum much more power than 26 temp.

Let me tell you guys the ampare starts coming down within 5/10 minutes under designated conditions

Let me know you guys if i am wrong.

Let me be the first person to tell you that you are wrong. Outdoor temperature has nothing to do with it. It is the indoor temperature that determines how much power the compressor will draw.

A friend of mine believed that car AC works on outdoor temperature

Outdoor temperature has an indirect effect though.

@qurban2020
No matter how hot it is outside, if you set it to 16C. It will start at its lowest value and keep going up till max value. Now the time it takes to reach e.g. 2.5A to 10A might be small (less than a minute) but it is not within a second.

vacuum is done on lineset .....ask that idiot to get some knowledge before selling units before someone make them run in circles complaining them to consumer court

Ask them to install everything and don't open services valves .....get vacuuming and procedure outsourced by paying extra

[Thinking]

i tried to explain them this thing. however it seemed they couldnt grasp the concept :(.

[SER_GTR]

Lanat Bhejein ..But Dont Install It W.o Vacuum! Else Performance Will Be Greatly Compromised

[qurban2020]

Brother let me tell you in a rainy day the max ampare will never reach the peak as it use to be in extremely hot sun weather.

I am not talking on imagination i have installed a Ampare meter and carefully observed the readings.

And if outdoor is nothing to do with comsumption then why ac cools faster when the outdoor is in shade and why compressor works harder in sun than in shade.

[qurban2020]

Brother if outside weather is cool then ac wont go upto 10Amp as it used to be in hot sunny day.

It should not go beyond 7 -7.5 Amp

[qurban2020]

These Technicalities i can tell you because i have installed Haier, Kenwood, Super General, Orient, Panasonic and both inverter and non Inverter and even i have installed Window ac as well.

I am in the line on Construction therefore i try to observe everything carefully

So, the right procedure is to do it slowly and in small steps to let the liquid refrigerant boil off (under low pressure) and turn its state into gaseous/vapours as it passes through the manifold gauge.

[Xulfiqar]

you have the right concept here.

[galacto]

I see. Thanks!

[HellsGuardian]

I don't know what are we even discussing?

[SER_GTR]

I Can Agree To Some extent That Smart AC's Do Had Outdoor Sensors Also As Input But Its Used For Safety And Serve Other Purpose

It Just Simply Won't Work Exactly As You Mention.. The Inverter Wth Variable speed compressor starts pulling zero to minor amps and slowly starts compressor .. then as per indoor temp set.. it starts cooling which usually required full throttle as the desired temp and ambient temp diff is too much....

keep in mind that indoor temp is what matters and works ...heat which is being pumped out is from indoor not outdoor so it work by comparing indoor temps with desired temp and it varies speed when desired temp are reached ... it throttle downs and maintain that

outdoor temp might sense and adjust things for safety precautions and protection of compressor and performance of unit and also for troubleshoot in case of failure

for you question regarding performance in shade vs direct sunlight so its obvious that condenser which is directly getting hit by sunlight will not work as effective as one with no direct sunlight as temps keep fiddling beside the heat released from indoor unit ..so its double work for it

SIr, need information.

What is the difference between Sada Ac, Inverter and DC Inverter.

Need 1 ton and please recommend good brand - Karachi less then 50K.

Thanks

[SER_GTR]

Sada AC....Conventional R22/R410A Gas Type... Price Varies 35k-45k For 1 TON

Inverter /DC Inverter ...Variable Compressor R410a type...Save Electricity And Can Start On Capable Gen/UPS Also...Price 60-70k for Diff Brands

Check Above For Brand Discussion And You find Plenty Of Info to Read Above

[automakerz]

Thanks alot

[automakerz]

Sir,

Do update me on midea - is it warranty claimable and made in ?
I need 1 ton Inverter for my room. Price etc.

Regards
