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


Good idea, but why not try something different. Put a few large fans in the
roof of the shed with a covering to stop the rabbits injuring themselves.
Set the fans to suck air from the hutch and blow it out. This will drag
cool air in and take the warm air out. Cover the tops of the fans to stop
the rain getting in, perhaps a piece of wood a few inches above. Try a few
kitchen/bathroom type fans in the top of the walls. They can shift a very
high volume and if mounted correctly are not noisy. You might end up
freezing the poor rabbits with their own aircon.
