but do the two pipes operate at the same temperature?
and yes they are touching,copper to copper, physically alongside each
other inside the foam.

i wanted to add air conditioning to my new home. i have copper
tubing(4m) ready laid out but i noticed both tubes are taped together
inside the same insualting jacket. most a/c installations i see the
refridgeant lines are insulated seperatelty.

will it have much of a performance penalty on the A/C or is it ok?
anyone have tubing insulated like this?

Hi,

The cooliing effect comes from the liquid in the 'flow' pipe changing
to a gas which returns in the other 'return' pipe, so having them
together won't matter.

The insulation is mainly to stop condensation forming on the colder
return and dripping everywhere, it will also stop any stray heat
coming from the flow pipe too.

cheers,
Pete.
