Which is more energy efficient, setting 16C and ON for 3 hours or set at 22C and on at 6 hours?

if you want the best result, set for 16C, max blowing speed, switch on your fan, after 15min, then only set to 22C or automatic function. You may still keep the fan running at minimum speed.

Air circulation plays a very important role here, if air circulation is not good, you will feel taking longer to get 16C.

i guess the answer would be it depends on the units EER at specific loads. if you have an inverter which is very efficient at lower loads then you would be best of by using it on lower settings for a longer period. for example i set all my inverter a/c in the house to 28° but i never off them. if you have a regular aircon which only has full load or none then you might be better off running it for the shortest period of time but under _continous_ full load. avoid on/off. i hope this helps a bit.

You can consider York WinterSpa too, if you want air-conditioner with hot water system.

wdarke,

1x2 HP inverter
1x1,5 HP inverter
2x1 HP inverter
2x1 HP non inverter (high EER)

monthly bill (no cheating) 300-350 if we are at home the whole month. 350 if got mostly hot days, normal is closer to 300. but we did spend extra $$ on good insulated windows, good outer door and insulated the ceiling. so it's not just energy efficient units that do the trick.. it's the combination of all the little things.

for your information (and to allow for better comparison) we are basically we are cooling down 24.000 cubic feet of air in the house. this means (forgetting all other appliances like fridges oven PC etc.) cooling one cubic foot of air costs me less than 1.5 sen per month with a 350 bill. if i assume i also spend around 50-75 bucks for other appliances then the figure is even better but i just dont have that number. if you take my "guesstimate" then the cooling cost is down to 1.25 sen per month or less.

hope this helps.

my one is non-inverter 1hp inclusive of installation is RM1050. The aircond man already service my company aircond system for a very long time, maybe thats why he charge me an honest price. smile.gif

my 1hp model is MS-GC10VD n the 2hp model is MS-C18VC.

For more accurate calculation, pls used btu instead of hp.

For inverter, i think better to get Daikin but currently i'm using York and Acson non-inverter.

Daikin inverter can used back conventional piping and coolant from what i heard, hence installation is cheaper and when u change aircon next time, u can change to non-inverter type

so Daikin is more economical even with inverter? What about its service maintenance?

harrychoo is right, Daikin uses conventional piping and gas, therefore normal standard charges applied for maintenance.

I believe Panasonic and Mitsubishi inverter type airconds are using conventional piping as well, nope?

Hmm no. I think all inverter airconds except Daikin uses R410A. Any aircond that uses R410A refrigerant must use thicker copper piping, due to higher operating pressure. Daikin inverter uses R22, hence "conventional" copper piping will do.
