Air-conditioning dos and don'ts: Refrigerants and the law .

The molecule size of R134a is smaller than that of R12, so there was concern that R134a could leak out through the hoses and flare fittings that R12 systems used. R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn't cool as well as R12.

6.9 Flooded evaporators - SWEP

Unlike in a direct expansion (DX) evaporator, the refrigerant is not fully evaporated and superheated at the flooded evaporator outlet. The leaving refrigerant flow is a two-phase mixture with typically 50-80% gas. Flooded evaporators, which are sometimes called wet evaporators, are divided into forced-flow evaporators and thermosiphon evaporators.
