Brivis Ducted Heater/Air Condition

Our Brivis ducted heater/air condition system has two zones. With the
air con on one zone works OK. Swap to the other zone and initially the
air con works but after 15 minutes or so the air flow from the ducts
hardly flows, the air that is flowing from the ducts is no longer cold
and leaving the air con on causes the big copper pipe outside the house
to form ice.
Any ideas what could be the problem?

Can the air get from that zone back to the return?
(You do know where the return is fitted, don't you?)
Despite having more than one zone where cool air is
sent, all A/Cs I've ever seen have only single return.
You might need to put a vent panel into the door that
divides the two zones.

Clifford,
Thank you for your reply.
Yes air does go through the return, initially, but then as there is a
drop in air coming out of the ducts there is also hardly any air flowing
to the return.
I have now noticed that it is also happening with the heater the same
zone initially works and then after around 15 minutes it hardly works.

Perhaps the return air duct is crushed and collapses under the vacuum?

We recently had a problem with one of our split system units where it
would hardly produce any
cooling or heating. Upon inspection we noticed one of the copper pipes
connecting the outdoor
to the indoor unit had ice on it (where it exits the outdoor unit).
The problem in this case was low
refrigerant caused by a small leak in one of the fittings. The leak
was fixed, the refrigerant
replaced and it now operates as it should both heating and cooling
(and no ice on the pipes).
Maybe your iced-up pipe is a sign of low refrigerant?

Does not make sense in this case because one of the zones is working.
If the refrigerant was low, which is common to both zones, none of the
zones were working.
