Some General Aircon Questions, Need Your Help

[flash88 0]

Hi all,

I am new to all this aircon stuff, so I have some general questions, hope you guys can answer some of my questions.

My current aircon is Sanyo, non-inverter, a system-2 and a system-3, the latter is broken, repairing is not an option.

The aircon uses R22. I live in a condo about 10 years old.

My questions:

- The piping in my house is concealed, so I assume that it will normally not be replaced when installing new aircon, is that correct?

- Will I be able to switch to R410A aircon, or will that not be possible without changing the internal piping?

- My system-3 is the one that needs replacement. It has 2 separate compressors in the box, one for the 2 common rooms and one for the MBR. I imagine that this is more efficient when using only one of the rooms. Do all modern non-inverter types have separate compressors or does it depend on the model?

- Since I am hardly using the aircon at all, i am considering buying non-inverter. With regards to life-time, is there a difference between inverter vs non-inverter?

- What is the target temperature that they normally use to determine the capacity? 18C, 20C, 22C? I usually have it at 25C, does that mean I can do with a lot less capacity than would normally be advised for a space of that size?

Thanks in advance for your help!

not intending to hijack this thread, but since it is titled "general aircon questions".. maybe i can ask mine here too!

am searching for an aircon for my new place, and have been hearing abt Armaflex vs Kflex.

so which exactly is better?

Armaflex 1/2" or 3/8"?

Kflex 3/8"?

what exactly is the difference?

am concerned about the possibility of condensation on my trunking as they might be concealed by the built in wardrobe.

thanks in advance!!

Thanks for your answers Aron, appreciate it.

I have decided to go for Daikin non-inverter system (R22), there was a good offer. Very simple model from very good brand (at least that is what i read everywhere), don't think I can go wrong here.

I will have them do pressure test on 2 units (these had leak in compressor), the 3rd one I trust to be okay, it has always been working flawlessly w/o top-up.

Am somewhat surprised that concealed piping not designed in such a way that it will at last least 20 years or so (or is it?). Nobody wants the trouble of replacing the concealed piping unless absolutely necessary.

What material is used for the piping and what usually makes them leak?

PS @ chinpokomon: feel free to hijack, my questions answered :-) good luck!
