isn't it the CONDENSOR (not the evaporator) where the refrigerant gas is
pressurized and condensed into a liquid, and the EVAPORATOR (not the
condenser) where this liquid is evaporated back into a gas???  The
evaporation is what produces the cooling, much the same way that liquid
sweat evaporating from the skin cools a human body.  That's why the
evaporator is inside the van...to blow cool air to the front, and the
condenser is outside the van...to cool the warm refrigerant with ambient or
fan forced air.  Hold your favorite aerosol can upside down and push the
button.  You are now evaporating into the air, a liquid which was condensed
into the canister and under pressure.  The canister is your condenser (high
pressure), the button your expansion valve and the temperature drop you feel
of the resulting spray is the cool you feel from your evaporator (low
pressure).  The only difference in this case is that it's not a closed loop.
Reverse the whole process and you have a heat pump.

Let think of it like this:
You can not compress a liquid!
High pressure gas out of compressor
to evaporator that turn the freon into liquid
Liquid goes to condensor turns to low pressure
gas.  Low pressure gas goes to compressor
and the hold thing starts all over again.
