installation perspective
Front wall as in facing outside where sliding door is best location since min hacking. One hole for the pipes to run out. Unless not enough space (very low ceiling clearance due to plaster ceiling, etc ) To replace pipes is only external work with minimal intrusion.
Tv wall - need to hack. long runs of pipes and drainage plus concealment unless using simple casement. Risk of leakage then how...need remove tv furniture (if tall) before rehacking to fix leak or replace piping. Any wall paper to remove or replace after?

Maintenance perspective
Is there any extra work for the air con guy to service above tv wall compared to front wall?
Like take down fragile things or cover tv and furniture below from potential dust fall out when opening air con.

These are insulation jacket/sleeve to prevent condensation on the pipes causing mildew/mold to thrive which can be a health hazard.

The tradename is Inaba denko Paircoil which most professional aircond/HVAC call it Paircoil.

The best in trade are from the UK, Armacell [/edit which manfactures Armaflex. /edit] Use in various industries.

There's also a Korean Paircoil [/edit manufactured by Smartco /edit]

My mechanical engineer friend in SG educated me on the importance of individually insulating the pipes so that there's no mixing as well as the reasons of condensation and what it leads to above. Worldwide standard mandates individually insulated pipes wrapped over optionally with PVC to protect them if they are [/edit NOT /edit] designed against UV damage. Don't know if the Green Building Index have taken this into account.
