Is the Liquid Pipe Size and Gas Pipe Size important?

My house has the aircond piping ready in living room and master bedroom, I already bought 2 aircond (1.5hp & 2.0hp) without study the aircond suitable for use or not. now worry already..

Yes the piping is important. With wrong size your aircond cannot be install.

Assuming I'm planning to install an aircond now should i go with the new R410 piping size or the old piping size.

depend if you are doing conceal of the piping or not.

I just checked the brochure aircon man give me . Panasonic STD and inverter series using same piping diameter according to the rated horse power but dunno is their STD one still using r22 gas a not

Thanks. Hopefully can install and worst case need to change my aircond if cannot install on that existing pipe.
Should do proper research before buying it.

Daikin DC Inverter aircon, according to their advert they are using normal piping.. anyone using them?

Hi got a question to ask. The A/C man came up to my unit and said that we need to do adjustment to the pipes as they are too far apart. From what I see, the copper pipe, power cable and pvc tube are wrapped quite near (at least physically touching each other) to each other. Not sure if I get the correct meaning. My pipes are all concealed pipes. I wonder is this guy trying to get more money from me as I can't find his reasons logical.

Will post up photos if required later.

Does that mean if external piping should be a breeze when it comes to installation? Since its old house and not too concerned with the cosmetics. Thanks.

If installation is just external piping it will be a lot less work for installation.

Bro, if external piping under 2 meter and have power point ready, installation can be done within an hour.

normally AC are using 1/4" and 3/8" copper piping. there are two type of thickness for both. which ic 0.51mm & 0.56mm

typically, MOST installer will choose 0.51 due to its cost. I do believe developer will choose this compared to latter one. York has manufactured Inverter for quite sometime. but it used R22 gas which is known as NeoVerter(singlesplit) & Transverter(multisplit). It is recently, everyone is talkign about Inverter Inverter due to Panasonic`s bombardment of ads everywhere. Now, most of the inverters are using R410a due to montrael protocol. As for this gas, it is wiser to choose copper pipe with thickness of 0.56mm

when you mentioned about NORMAL piping, I do not get what you actually meant. Piping in the unit or for installation?

cheers

i think at 25C it is just nice. i don't like being cold and have to cover up my body to keep warm

At what temp should we set it at then, and why?

guys,

which method is better:

1. Install Copper and Piping during the renovation (without order any air con)
2. Order the air con and let the air con man to install Copper and Piping

reason is, i plan to install the air con at later stage, but i intend want to install the piping and copper.

i'm kinda confuse which method to go for.

this is only rule of thumb... base of human perception.

it is consider to be the comfort zone base on trial and error.

there`s no specific answer for this question of yours.

P/S 25C is consider to be cold for me while it is hot for my wife. We argue about temperature setting everynight before going to sleep

Option 1 will be better.

25c is base on the international R&D for human comfort temperature zone. Pls google.

20c is for measurement standard temperature.

Even if you set your aircon to 25C, you don't get 25c in your room. Get a thermometer to check. You only get about 26c-27c. Depend on which corner of your room measure and the aircon blowing.

that depends on where you want to put those airconds in your house.. if conceal pipings are required it would be clearly better to do it during renovation...Unless all the sets are directly between a Wall for both exterior n interior units where you don't have piping laying issue... Ngam?

Guys, any feedback on Samsung air con? I visited an air con shop and they highly recommend Samsung. I'm quite skeptical cause Samsung does not seems to be the in-brand in air cond. but the seller claimed that they are actually old timers in commercial air cons such as centralised air con in mall or hotels. any idea?
