using grade 23 copper pipping and with proper piping installation we should not have the above mention problem rite?
this also add cost becos the need of thicker insulation n copper piping.

but of cos, if in future, the cost is lower, surely all will choose inverter.

problem is NOW. the cost of everything on inverter is high. so when consumer tink tat inverter is gd, "i wan to get inverter", but so exp. tats jus my opinion btw, i guess alot of ppl will also like tat tink.

The shorter the piping and the less bent of piping is the best and remember if on landed property vertical height of piping do not exceed 5M if not compressor oil will not return and your ompresor will die very soon. If no choice you need to installed a oil seperator or u-tube installation.
hmm...but main cause of gas leak is joining of 2 copper pipes together.

so if got joining 2 pipes together, than be prepare to "sian".

my ideal location is at location D, and the compressor will be just outside windows, so confirmed less than 2-3M........... between the distance....

so is location D a good location? if i would like to feel the air colder on bed??

becos i scare hot a lot one.........
If I were you i prefer E which give better air circulation in your room and somemore only 3 bent very optimal installation. Also tell the installer do a good gradient for you drain pipe and you should have many sweet dream.

if we talking about standard joint of pipe(brazing) you need to charge in N2 gas to prevent oxidizing of internal of copper pipe when brazing the 2 pipe together, but in market nobody will do this for you. But at least ask for a thorough vacuum, but most of the market installer only purge the system with refrigerant and seal that it (time saving)

The incline of the drain pipe so you will not have drain pipe choke problem after many year of using.

Air con configuration

Hi Air con gurus! I need some urgent help on the following.

I just bought an apt and I intend to replace my existing air con systems as they are 8 years old. The current set up consists of a System 3 (Master room 12k BTU, Guest room 9k BTU, Study room 9k BTU) and a System 2(Living and Dinning room 12k BTU each).

My air con usage is typically daily (Master, Study rooms) and occasionally (Living/Dining/Guest rooms).

I arranged for 2 site inspections but both technicians proposed different configurations:

(A) Follow existing configuration, ie. 3 rooms (System 3) and Living/Dining (System 2). This technician reasoned that this configuration saves on servicing as (given my usage style) I need only to service more frequently on the outdoor unit of System 3 than outdoor unit of System 2.

(B) System 3 (Living 12k, Guest 9k, Study 9k), System 2 (Dining 12k, Master 12k). This technician reasoned that this configuration enables both outdoor units are more evenly utilised, which is better in the long run.

I'm indifferent to both but what do you think? Do both explanations above make sense? Or is there an optimum configuration not stated above?

Thanks so much!
