Hi guys!

Quite new to all this air-con stuffs, so wish to seek all experiece people here to guide me.

Recently, my old air-con spoiled already, so intend to change a whole new system.

Going for a Inverter system 3 air-con, looking at Panasonic, Mitsubishi Electric and Daikin.


I got read a couple of pages here regarding about the Armaflex insulation & copper pipe stuffs....

What is this actually? on the Armaflex and copper stuffs?


And what to look out for?


Gain City a better choice?

Regards.

To people who are going to install aircon, this air purge will be done just before they on your aircon for the first time. They will purge the air while they are doing the final tightening of all your nut connection @ the outdoor unit.
I think that is what my installer had done.although i didn't see how he did, I heard the "chee chee" sound. the gas out sound.

Would like to check with you guys here at what temperature settings do u set at night when u sleep?

I tried different fanspeed and temp settings for the past few nights from 24 to 27 degrees.............finally managed to find that 26 degrees is the ideal one.

The old people saying, do not let the aircon blow the cold air directly at u, cos it's not good for u, but instead adjust the lourves to blow the air in the other direction. Do you guys do that or dun care..........

R22 is still cheaper compared to R410a.
I would advise all bros/sis to install system using R22. R410 still not commonly used in hdb.

Armaflex is the black insulation material than wraps the copper pipe. The thicker the better.

Standard copper pipe that installer give is Gauge AWG 23 or 24, this is ok if yr aircon is using the old gas R22. But with the newer R410A gas, as it's operating at a higher pressure, installer recommend guage AWG22 thicker pipe. Some installer uses AWG23 which they say is good enough.

ooh ok, thanks for the enlighten on the copper pipe and armaflex.

so for brand wise, which is better? in terms of saving consumption and quiet?

bro, DYOR la. Go browse thru' NEA website.

For myself, i choose MHI becos of the features i wanted, ME dun have.

In terms of energy saving. ME is the 1st, MHI is 2nd, Daikin and Panasonic is the same....3rd most energy saving.

It also depends on yr usage pattern......like every night u use aircon only for 1 room or 2 room or all 3 rooms all on.

Still have to check particular model. Eg. brand A' s model A is more energy saving than Brand B's Model A, but Brand A's Model B may be less energy saving than Brand B's Model B. So just say certain brand is more energy saving is not so correct.
