Heat shielding air con lines?

[Patcheon]

Was cleaning my sunny engine and I notice the aircon pipe was fix over the right side of the engine block. As there is a lot of condensation on it, it wasn't insulated. Was thinking should I insulate it so that the air con fiuld inside wouldn't be heated up so much by the heat from the engine. Had anyone done it? What sort of insulating materials should I use, was thinking along the line of those use to insulate aircon pipes in houses but don't know can they stand the heat from the engine. Saw some heat shielding tapes at Autobacs that are metalic on one side but 1 coil cost around $100. That seems quite ex for such a small project.

I not sure what kinda "insulation" are using. I roughly know the place... thinking of going down this weekend. Think the shop name is called res-air. U can check it out in the yellow pages.

just go to air con shop to buy the insulting "sponge" they use to warp the air con pipe lor... cheap one... same effect/

 

i did mine that way... plus it is good to wash your raditor with the liq they use to clean the air con at your home.. it is the same theroy.

Hi All,

For better effect, wrap aluminium tape over the pipes before the insulating the pipes.

Can buy fm Daiso at IMM $2 only.

Did that for my car, now can part-time deliver ice-cream for Walls.

why need to wrap aluminium tape before insulation leh??? CAn use those kitchen cooking aluminium foils??? Would it be the same??? Anwyay.....the air con piping above the extractor already wrapped with those black sponge insulation already leh......so should i add more??? make it thicker???

 

I wann part time deliver ice cream for walls also leh.... :P

Hi S2077s,

I was refering to pipes that are not covered (that are found with condensation).

Kitchen type can also ,use scotch-tape to hold them down before insulation foam.

Or foam first then wrap with alum foil or add foil to existing foam get warm as well.

It all depends to what extend u want to go to block away the heat.

hmm... can explain why the aluminum foil works??? insulations is better right>?>

[Str2]

Aluminium-foil is to reflect the heat away.

Foam is to prevent the heat getting thru.

So alum-foil cover foam better than just foam alone.

hmm what abt wrapping the insulation outside...

what i think is that when u wrap inside the heat is actcully trap in the insulation form... nothing much u can do abt it..reflect out also goes into the form
