Compare the duty the room needs with the duties the various styles of compressors are available in.
Screw and semi hermetic compressors tend to be available in bigger sizes and are more suited to commercial and industrial systems where reliability is more important than initial cost.
The hermetic and scroll compressors tend to be used in smaller systems where initial purchase costs are what determines which company wins the contract.
