I do not think that there would be anything instrinsically wrong
with
a unit where both the evaporator and condenser were contained in
the
same housing, it is quite a common practice for ducted sytems.

The only thing I would be wary of with a system like this one
(and I
have never seen it), would be noise and vibration. With this
system
the compressor will be mounted in your attic space, and this
presents
the possiblitly that vibration will be transmitted to the
building
fabric in your attic, and possibly resonate across the whole
attic.

The other thing that needs considering, (and I guess the
supplier
manufacturer would be able to give the details), is what size /
length
of ductwork is permissable. Generally the more ductwork, the
more
static resistance, and possibly less airflow. Get it wrong, and
this
will serioulsy affect performance of any unit.

As I said I have never seen this unit, but that is one aspect I
would
be keen to see operational before I committed to such a sytem.
Do they
have installations which you can go and inspect prior to
purchase?

Also, check out the capacity of the unit, and perform a heat
load
calculation on your property beforehand. For general home /
office use
I would use a reckoning of somewhere between 125 - 150 W / sq.
Metre,
although for rooms that do not get any solar radiation (direct
sunlight) you could drop as low as 85 W /sq. m
