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

[zeus65]

and what about accessories?? did you get copper installation kit ?? drain pipe?? any other accessories??

[matifkhan]

Those components take less energy and I don't think we can save much feom those. Blower speed is user adjustable, similarly outer fan is not too much power hungry. Its just the compressor basically which matters. Rotary vs reciprocating vs others have their inherent advantages and disadvantages but that should be left for a separate thread. Refrigerant can play a major part due to its own characteristics, cooling efficiency etc but these days almost all are using same 410A. R32 is another one but is used only by Daikin and probably LG too.

[zeus65]

yes, compressor and refrigerant play the major role in energy saving with cooling efficiency.
may be this 5 DC and full DC is just the gimmick to attract the audience.

[kick_in]

I've no idea about t1 t3
How do I find it?
It's both heat and cool and full DC I believe
Starts at 135v
Model number is Hisense HBR1800HC

Copper installation kit? You talking about the wire?
Yes everything was available didn't have to buy anything from shop, technicians just came and installed it in within 15 to 20 minutes

[kick_in]

Its T1 just saw the sticker

[zeus65]

yes, that's good mate.
most AC have T1 compressors. T3 are for tropical areas, where temps can go 50 degrees.

Guys if i have to choose between dawlance, orient and TCL. Which is better choice? price is nearly same. TCL gives 3 year warranty and is also assembled in Pakistan.

[Thinking]

i would go with dawlance coz of their 12 years warranty.

[zeus65]

12 years warranty seems understandable if the product lasts that long, like in case of refrigerators, washing machines etc n even conventional ac lasts around 5 years. But haven't heard of inverter ac to last that long. I think compressor warranty shouldn't be considered for buying an inverter ac.
I hope to see inverter ac to at least last 5 years. That will be considered a good ac.

[HellsGuardian]

why would inverter not last as long as conventional? considering both are made by same brand in same year so same quality.
Btw in my house i have conventional ACs that are easily 10+ years old. Dawlance, mitsu, sabro

[pwuser152809657887]

salam, any brother having experience of Haier UPS enabled AC??

[zeus65]

I think the mor sophisticated technology ia gettin, the more prone to faults it is getting.
But yea dawlance has thia plus point of giving 12 yrs compressor warranty. Pel is also giving 10 yr warranty.
Only these chinese and international brands are not providing such warranty. Don't know why.

[zeus65]

Guys, how much energy saving you are getting from inverters.
My 1.5 ton dc inverter, kept at 27 temo, low fan speed, swing mode on, starts cooling afte few min and takes 6-7 amp n sometimes to 8 amp.
It works so for an 30 to 50 min at night n pehaps an hour or more in daytime. Then it drops to 3.5 - 5 amp range for another hour or two. So, in total after 3-4 it drops to 2.6 - 3 amps finally. It is the lowest i m getting. Energy consumption is around like last night 4.5 units in 7.5 hours.usual voltage is 200 to 210. No stabilizer attached.
And one more thing what i feel is that blowing air is not cool enough like my 8 years old conventional dawlance ac.
Any remarks guys?

[Thinking]

it translates to 25% lesser bill. my bill for 1.5 TON used every night dropped from 11.5K/month to 7.5K/month once i shifted to 1.5 TON inverter.

[zeus65]

well inverter do save the bills, there is no doubt in it. but to be precise, i want to understand how does some people are achieving 1.5 amp just after 15-30 min of turning on.
i know many factors play a cumulative role to achieve ideal results.
so, if ac unit has no any faults or gas issues then, following factors what i know matter to achieve maximum results.
1. room size to tonnage
2. ambient temperature
3. set temperature
4. minimum energy consuming setting on AC
5. room insulation
6. exposure of room to direct sunlight
7. time of day. i.e. at daytime outer temps are higher than at night.
8. placement of outer unit in shade or not.
9. distance between inner n outer unit (mine is like 22ft, though manual says it lies within the range, but it is quite large)
10. no. of persons in the room, might also matter.

[kick_in]

Please don't go for orient
Cheap quality and pathetic customer service
If I was you I would go for tcl because of their quality and 3 years warranty

[kick_in]

I'm using the same settings as yours.
However I dont have ampere meter to check the consumption but during day time I run it on Solar so I do see wattage consumption. So this is how it is:
Starts with almost 60w consumption
Moves to 500w within 3 4 minutes
Then after few minutes it uses around 1850W, this is the highest consumption of it I've noticed
Then within an hour it gradually decreases consumption to 1200-1400w, and then after 1 more hour it uses almost 500-700w. Didn't noticed the consumption after that
However I can say it uses much less electricity during night time as it's consumption drops to 600w within an hour of starting it

I have Gree's 16000 BTU unit in my room. Measurements are 15x13x10. Not directly exposed to light. Sunshine available through window from 1500 - about 1700. Ground Floor. No false ceiling. Major heat producing device is 40" LED TV, which remains pretty much switched on for most part of the day. Shuts down at around 0100 (night / morning). When ambient temperature is between 35 to 40 and set temp is 26, it takes 2.2 to 2.6 Amps on average while falling to 1.4 Amps in the mroning. Around 0500 to 0700. Highest I have seen were 5.5 Amps being drawn one odd time when temp set was around 20 or less.

Few things I have noticed for optimum savings:

Keep the fan on auto. (Most important)
Keep temp to 26.
Swing doesn't matter much.
Don't use I Feel.

And oh YES, absolutely. My 15 years old 1 ton Dawlance (conventional) in same room when set to 26 degrees produced far superior cooling. Can't understand why, despite having studied AC/ref cycles during BE.

[matifkhan]

1850 is too much. My crappy Haier used to go that up. I scrapped it within two months of purchase. It shouldn't go that much high. Gree /Acson don't take that much until you've set temp to 18 or 16 degrees. How big is your room? It should hover between 2 to 6 Amps.
