component sizing
(OP)
I understand the major components of the refrigeration cycle should be sized to match the cooling load. What is the downside to using a compressor that is too big for the application or an evaporator for that matter?

Case1: Only compressor is of bigger size.
Evaporator can't deliver dry gas at the required and the result is the liquid stroke and subsequent compressor damage.
Case2: Only evaporator is of bigger size.
This subsequently increases (beause of liquid accumulation in the evaporator)overall pressure in the system thus creating leaks and energy loss.
Case3: Chiller is of bigger capacity when compared to your demand load.
Capacity control becomes difficult. Hunting of the system takes place thus reducing the life of the equipment.
