What is the difference between one stage direct expansion cycle and one stage flooded cycle in CoolTools?

In CoolTools, the cycle analysis simulation allows users to compare the performance of one stage direct expansion cycle and one stage flooded cycle. The direct expansion cycle uses a single stage of compression and expansion to cool the refrigerant, whereas the flooded cycle uses a flooded evaporator and a single stage of compression and expansion. This comparison enables users to determine which cycle is more suitable for their specific refrigeration system design.
