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?

regards,
Sam

It will have a slight performance cost, but unless they're touching, not
enough to worry about.

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.

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.

Hi,

I might be slightly wrong on this, it would be worth asking the
manufacturer or on somewhere like:

www.refrigeration-engineer.com

Hi,

No, the liquid carrying 'flow' pipe from the outdoor unit condenser is
likely to be warmer than the gas carrying 'return' pipe from the
indoor unit evaporator.

This should not a problem if they are in contact as the colder the
liquid in the flow pipe the better. However some air con units allow
some expansion on the liquid in the flow pipe at the condenser which
could make it colder than the return.

So it would be best to see what the manufacturer says or ask on that
forum I gave the URL of.

cheers,
Pete.

It will give you a performance and energy efficiency penalty, but by
how much is another question. IOW it should be ok but is less than
perfect.

Refrigeration insulation is available at Kitsons, It's like a figure of
8 so tubes can be run parallel.
