Help! What Brand Of Aircon To Buy? Inverter Or Non-inverter?

[wensi 0]

Hi,

Hope any kind soul could suggest a solution for me..

Here's my situation and usage pattern: 3 bedrm + Living, 2 pax staying only

MRM (bigger as I expand into Rm2) - 'ON' aircon every nite, at least 8 - 10 hrs

RM2 (smaller by half, area taken by MRM) - empty room, no uage (occassion mum would drop by but rare!)

RM3 (Study rm, smaller by half, area taken by Living - short period, 2 - 3 hrs, not daily

LIVING (bigger, almost 35sqm) - 'ON" fm 8-12pm at least 5 nites a week. Weekends longer hours if friends drop by.

Do take note that it'll be VERY RARE tht i'll turn on 2 fan coil at the same time..

Based on above, pls advise if I should go for Inverter or Non Inv? Cost is also a important factor.

I was told by someone, tht the refrigent for Non Inv (R22) will stop supplying to market from 2015.. That's only 7 years away, does it means I'll hv to change the WHOLE aircon system by then???

Advise/suggestions pleasssssseee...

if i were you, i will get non-inverter type becoz not all the air-con are on everynite. inverter works in such a way whereby it could reduce energy comsumption by lowering electrictiy used and fan coil turns at slower speed. as for non-inverter, it's either on or off. nothing in between(lower current drawn).

And given the price for inverter is more exp, if u're not turning on all the aircon everynite then the additional cost to spend on inverter system cannot be recover back in maybe 5yrs time.

Ppl get inverter system becoz it saves electricity over a period of few yrs and thus to say they get back the additional money they spend on inverters.

as for non-inverters, it depends on what brand u're getting and how u wan them to be arrange becoz most brand has two compressor and some has one only. best is to ask the salesman how inverters and non-inverters work. becoz from my understanding, money is saved on a long run when u use inverters with more rooms usage.

for non-inverters, they are not as cost effective as they either turn on or off but never in between. the most expensive part is when the compressor start-up, it draws a lot of current and thus our bill go up becoz of that few second of high power when it startup so always set the temperature higher becoz it'll cut down the number of times the aircon compressor has to startup once the thermostat's drop beyond the threshold. eg. is 16degrees celsius obtainable throughout the whole nite? likely no or mabe onli for a short while so compressor has to work to 16degrees and off then after half an hour, startup again. imagine how much u';; actually spend.

but for comfortable constant temperature, inverter is the best becoz it's on all the time. adjust the temperature by turning on compressor maybe at 50% power or less to maintain the temperature w/o turninng itself off.

hope this will help you understand aircon better. so conclusion is.... get a non-inverter unless you have all the rooms with aircon on everynite.
