Help Inverter Air Conditioner V Standard Air Conditioner Which One Shall I Buy?

[rexnong]

I am about to buy a new air conditioner unit for my sons bedroom

The room is facing South and is hot as hel_l most of the day on the second floor

Its 4x4m2

I was going to buy a 12,000btu standard type air conditioning unit (panasonic) about 18-19000 baht but have also been looking at inverters as he will be using the air con about 10-12 hours every night which i am told is going to save money on the electric bill as the inverter type dont shut off when they reach the temperature like a standard type

The store have told me i will have to have a 15,000 btu as the 12,000 inverter will be like a 9,000btu standard type due to the lomng slow start up to get the room cool

Anyone got any thought as the 15,000 btu inverter is around 30,000baht (panasonic)

Or is it better to go with a Daiken? sanjo denkin?

Thanks In advance

[GungaDin]

I have a Daiken in this room I'm in now.

I wouldn't hesitate to buy another Daiken.

If you can afford it, get the Inverter type.

I'd also get a 2nd & 3rd opinion from installers, esp the smaller shops.

I have a Daikin inverter 12,000 in my 3x5m bedroom which is south facing, sun all day.Works great, about 5 mins to notice big temp drop. It has an economy setting which l use all the time and is very quiet in operation, no clicking on and off. Most important, it is cheap to run.

Where to buy daikin airco multi split on koh samui?

Thanks for info

the "store" has obviously no bloody idea about airconditioning, especially "slow start-up" inverters. and i have no time for further explanation as the Old Lady wants to be taken out for dinner. perhaps later more.

I bougt 4 Panasonic Inverters, 12.000 up to 36.000 btu last year Saved abt 30% ON EL.BILL SO FAR. Also bougt a Carrier 80.000 btu something for the hallway, now that cost me THB 6.500/ month 8 hours/day. Saep thot!But it really works well. Most days that unit alone will keep the house (165m2) fairly pleasant.

If you need to use your a/c 8 hrs+/day, go for the inverters. Daikin might be just as good as Panasonic, and now more brands are coming out on the market.

sajo denko is a hybrid, so no water in your house, no cool air.

I also have a Mitsubishi Heavy duty 14.000?btu in the laundry room, that one really sucks.

So, don't go cheap, inverters will save yoy a lot.

Good luck!

Thanks for your help i just checked the price for a 12000btu daikin inverter

35,000bt but they will put it on free

Panasonic 12000btu inverter i can get for about 26-27,000 bt

Sounds like a lot of money but should it save me much on electric rather than sticking a 12,000 btu standand samsung on for much less?

How much did you guys pay for a Daikin inverter?

Thanks for you help

I think it all depends on how long you'll be running the A/C for.

If you're a 24 hour a day Eskimo then the additonal cost will be recouped quickly.

If you're a 1 hour a day user then the unit will likely be well dead before you've recouped your additional cost.

[elkangorito]

Unfortunately, this all depends upon one thing...the size of the unit required to cool a certain volume.

If this is not calculated correctly, you may as well have a 'standard' a/c unit. Inverter or not, if the space is too big or the heat load is too high, you will be using more electricity than required (it will be running flat out most of the time).

If the a/c unit, inverter or not, is too big, it may behave in the same way as a normal a/c unit...it may 'short cycle', which ultimately reduces the life of the unit & will most likely fail to dehumidify appropriately.

If someone can tell me how a guy in a store can tell you the size of a/c unit you need ('site unseen' by the guy at the store) based on information supplied by the prospective buyer, I'll kiss my bum. It takes either someone with a bit of nouse to buy an a/c unit without a 'survey' or someone to conduct a proper survey in order to purchase the correct unit.

All of this 'heresay' is waffle & is not conducive to the purchase of an appropriate a/c unit to suit a specific location.

[Naam]

read ElKangorito! he is presenting facts and not rubbish such as "the unit does not click on/off", "this one really works well", "that one sucks", "i was told inverters save on electricity bills".

addendum: an aircon unit is like a wife, girlfriend or boyfriend. performance is based and judged on your demands... which vary.

but don't you agree with what i stated?

off topic: i think a booklet with a collection of "technical" advice on airconditioning derived from Thaivisa would be a huge success because it'd guarantee roaring laughter for the [informed] reader. still waiting for claims "my aircondition can beat up yours", "my inverter is capable to administer a cool blowjob at an ambient temp of 36.5ºC", "i liked my unit so dearly that i married him/her".

best of all and repeated umpteenth times "why do you need airconditioning? do it like me, just sweat!"

[villagefarang]

No snobby claims of being an expert from me. All I can say is that I have three Daikin Inverters and I am very happy with them. I would not hesitate to purchase the same again.

Why buy 6 when 3 seem to be doing the job?

i don't think anybody doubts your claim that you are happy. the question is whether it's worthwhile to pay 50% more for an inverter driven variable speed compressor over a conventional unit. inverters save energy only when specific conditions/demands prevail. if these conditions do not exist the additional expense is a waste of money, not to mention the considerably higher repair cost if something goes wrong with the outside unit.

[rexnong]

Thanks for all your help but since its going to be used around 10-12 hours every day i am going to go for the inverter ,cannot quite afford a Daikin as there about 36,000 bt for a 12,000btu so going to go for a panasonic inverter which i have found for 26,000 bt

Can a daikin be worth an extra 10,000 bt as thats a lot of beer tokens?

[villagefarang]

When it comes to my comfort, a few more baht is definitely worth it IMHO. I have been lucky in that the guys who did the installation and subsequent service have been great.

Hope you will be happy with your inverter but be sure you get knowledgeable technicians to install and service your a/c.

your thinking is logical as far as the price difference is concerned. you have however not explained the reason why you prefer the inverter driven compressor over the conventional one because that difference is an additional lot of beer tokens. and if you ever answer my question please don't tell me because "it's going to be used around 10-12 hours a day".

warning: if you do answer as you indicated above my comment will be "a sucker is born every minute!"

Inverter type split system airconditioners are the obvious way to go, they proven to be more energy efficient and have low starting current.

But you must correctly size the unit with the area to be airconditioned along with the number of persons in the room at one time there are many variables including operating air temp (25C)

A compentant airconditioner installer will be able to give you the recomended size. You do not use a "salesman" from the store to do this.

incorrect information because of generalising. correct: more energy efficient only if certain conditions prevail. e.g. an undersized inverter unit does not save a single watt compared to a conventional unit because the energy saving feature "variable compressor speed" is not used. another important factor is to weigh whether the initial much higher investment and higher repair cost in case of break-downs is compensated by the energy savings.

[villagefarang]

Okay Naam, we get it. You are the GOD of air-conditioning and we must all bow before your omnipotence, but can't we be allowed to have an opinion without being put down and ridiculed? After all we are only talking about an appliance.

[david96]

The days of the wall mounted single unit airconditioner with electromechanical starting relay

and mechanical thermostat and large starting current are long gone. They were products of the last century.

Welcome to the world of the microprocessor, remote IR control, the variable speed motor, low starting current and digital LED display. These airconditioners are more energy efficient.

opinions are not facts VF. opinions which are not facts might give a wrong message, confuse and perhaps harm those who seek advice. i am grateful for all the good advice i found in this forum (i found a lot) since i joined nearly four years ago and therefore try everything to prevent harmful advice. if i consider (based on my knowledge) some opinions ridiculous then i will ridicule them and if i have no bloody idea about a discussed topic i keep my mouth shut.

p.s. and we are not "just talking about an appliance". the OP sought advice because according to what he wrote the difference of 10,000 Baht is a concern for him. that others are "happy" with their appliance and do not mind

spending "a few Baht more for comfort" is inconsequential for him and no advice containing something substantial.

pps. every other day somebody is seeking advice on car purchase in Thaivisa. some days ago i spend a few million Baht on an 18 year old car and i am very happy with it. should my advice therefore be based on my opinion? something like "do it like me, buy an old car and you will be happy."

Thanks again for all your help and Naam you are correct with 10,000 baht is a concern for me but really all i want to know is if a 36,000 baht daikin will be much better than a 26,000 baht panasonic both being inverters and both the same btu

I am not sure your point about why choose a inverter rather than a conventional one?

I am sure i am not alone thinking that inverters are much more efficient so long as you dont choose a undersized inverter unit

I have learned and had some great replies from TV and basically find that you can go around in circles with the replys but some are great and really you still need to make a choice of your own and the choice has to be an inverter as after looking at all the posts if it can save me money why go for a conventional type

P.s Naam car looks great .how many million though? i bought a bike for less than 200,000 and the wife is still pissed!

[villagefarang]

The OP asked "Anyone got any thought…" and to me that sounded like he was asking for opinions and perhaps customer satisfaction. Ridiculing people for offering their opinion in this case seems a little heavy handed, even if you disagree on a technical basis.

Of course opinions are not facts but a mixture of technical responses and testimonials of satisfaction, can both lead to a reasoned choice. In the end we all have slightly different processes by which we make decisions. I'm sure the OP is smart enough to sort through what we offer and make up his own mind.

Naam, on most topics you seem quite reasonable but when it comes to A/C topics you get a little mean, in my opinion. Not sure why that is.

No one got around to the question of brand names and why one might be worth more money than another. That is always a key question but difficult to answer, I suspect. Is one brand really that much better than another? Technical specs can be compared or customer satisfaction quantified but it can remain difficult to place a baht difference between brands. One suspects that some brands can demand a premium without being that much better and simply due to brand recognition. I am satisfied with my Daikin but have no way of knowing if it is worth more money than a Panasonic.

Villagefarang you seem to be spot on thanks for your help i also understand your thoughts towards certain posters

Thanks for your help to everyone i have made up my mind and sorry to all you inverter haters but its the way to go and i will let you know after a month if i think its good value when the electric bill comes

Daikin are the specialists in the field of Air-conditioning, all they produce is refrigerant, which is the gas used in the units and refrigeration units.

They have invented many World firsts, VRV (Variable Refrigerant Volume) being the most famous...the other manufacturers manufacture cash tills, calculators, cookers and a whole host of appliances and industrial goods...Daikin are the specialists, you wont regret it as long as it is sized up correctly for the load !

1. I am sure i am not alone thinking that inverters are much more efficient so long as you dont choose a undersized inverter unit

2. Naam car looks great .how many million though? i bought a bike for less than 200,000 and the wife is still pissed!

1. i am very happy with your answer RexN and think you've made the right choice based on logical thinking.

2. less than the price of one hundred inverter aircon units.

3. as far as my hobby car is concerned the wife is not pissed but even encouraged me to buy. perhaps the reason was that initially i intended to spend more than double on another even much older car.

back to topic. when i built my home four years ago i decided to go for conventional driven single speed compressors. reason: nearly all my units are placed and meant to run at full capacity (if and when they run) in order to achieve even temperatures and maximum dehumidification. as i have 19 units installed it would have been a bundle of wasted money without getting anything in return.
