I'm not a cooling system engineer, but I have a few queries about a cooling unit
on a roof.
The cooling unit has 2 compartments. The first compartment has a fan and what
like a car radiator at the back. I guess this is the condenser coil. The fan
draw air away from the coil rather than blowing ari directly on to it. I wonder
if this is correct.
The other compartment has a compressor and a Ranco pressure control for low/high
I was wondering if the cold copper pipes (about 15m long) from the cooling unit
that run into the
building should be bound together with cable ties or should they be separate
from each other.
One pipe has insulation (the cold pipe) and the other is a bare copper pipe
The cold pipe seems to freeze up and I think this is blocking circulation. So
is it better
to have these pipes tied together so that they are in contact, ie: the warm pipe
the cold pipe from freezing up.

I hope one of the queries was in the Yellow Pages for a *competent*,
licensed, insured, professionally trained, HVAC technician.
We can't *see* it from here, and from what you have said, its real obvious
that you don't have a clue.
Hey Jim, you know anything about cars? You see there are these pipes under
the hood, one is warm and the other is cold, should I wrap them together?
It is pretty much the same question, only in regard to automobiles.
With the info you posted, NOBODY could have a clue of what you are asking!!
What is the brand, model and serial number of the unit. Is it a cooling
only, cooling with gas heat, heat pump, chilled water, hot water heat? Which
is it! What are the tubes for?
