Answer to Question 1

They have to be larger to allow enough low-density, low-pressure refrigerant vapors into the compression cylinder.

Answer to Question 2

Positive displacement compressors move the gas by taking gas into a space and then replacing that space with something physical, like a piston. Non-positive displacement compressors operate like a turbine or fan.
