3. The fact that the refrigerant makes it's way into a LOW PRESSURE area allows it to evaporate or boil into a gas. The boiling point is lower at lower pressure, thus the lower pressure in the evaporator allows it to boil or evaporate.

4. You got it right in the evaporating substance drawing heat from the cabin. Your mixing system types with the filter/drier and accumulator. Pressure cycling systems have an accumulator and not a filter/drier. It is in a different position in the system serving a different purpose.
