Hi all,

I keep rabbits in an 8x6 shed. This is currently insulated with 2"
expanded polystyrene. Although this helps, it still gets very hot
inside during the summer months.

I am planning on buying a cheapy portable air con unit to bring the
temp down, but the problem is that these are very noisy (or so I've
heard), so I don't really want to stick it in the shed with the buns.

I have a double garage about 4 meters away from the shed, and had the
crazy notion of siting the air con unit in there, and piping the
cool / hot air to / from the shed via some kind of submerged pipe.

Am I nuts? Would I need a minimum diameter pipe? (Would drain pipe be
ok for instance?) Whats the best / cheapest way of insulating the
pipe? Would is be ok attaching such piping the air con unit of will it
cause problems?

Many thanks for any suggestions,
Lister
