Twice now my 92 Explorer has "blown" the compressor.

I think you gots gremlins in there.

Is it possible the compressor drew liquid refrigerant into the suction
side?

I think the reffigerent is supposed to be only vapor by the time it goes
around and come back to the input? Is that what the accumulator is for,
to prevent liquid from entering the compressor?

That is what seems most likely to me but it also seems to me that the
least likely time for there to be liquid is on a "cold start" when
it's idling. Isn't the liquid more likely to have condensed out after
it's been running for a while at higher speeds?

It's the same as when the refrigerant is in the can when you buy it, it is
a combination of liquid and vapor. Also propnae containers are the same.


When the system has been idle, the liquid will collect in the coldest part.
If it is all at the same _exact_ temperature, I'm not sure what determines
where the liquid collects.

It's not clear to me that there is any liquid when the system isn't
running. I know there is in the can but once it's in the car isn't
the volume of the system so large that it's all vapor until you start
the compressor? I'm asking, I don't know. Are you sure there is
liquid in the system when it's off? If so, that might be what's going
on, it's somehow sucking liquid in before it gets spread all over the
system.

In a properly charged and properly functioning automotive AC system
there is no liquid in the system when at rest.
When running liquid should NEVER reach the compressor. If it does, the
system is GROSSLY overcharged (or terribly iced up). The liquid
accumulates in the reciever drier and the high pressure line from the
condenser to the expansion valve or orifice where it is "sprayed"
into the low pressure side just upstream of the evaporator, where it
turns to vapour and returns to the compressor.

Mark is right all Refrigerant will migrate in or on coldest spot in any
system.
However it will also depend configuration of motor and setup of AC.
Some Vehicle have compressor on side of motor and some practically on
Bottom,
Bottom is critical point, if Vehicle sits for period of time not running
the refrigerant will getter at the lowest point, which in this case can be
in Compressor. Also one must be very careful how much oil is in system
and that will defiantly can do the damage. Automobile Compressor
or better with les then more oil in the system.
