The main reason is that the theoretical temperature difference is assumed to be an adiabatic process, which is not true in fact.
It can be observed that estimated mean value of end-to-end efficiency increases from 24% to 72% with a decrease in the polytropic index of compression from 1.4 (adiabatic process) to 1 (isothermal process).This clearly indicates liquid piston compression and expansion efficiency has a major influence on the end-to-end efficiency.

Taken together, these capabilities mean that a closed-loop adiabatic process cooling system can reduce energy consumption for process cooling by as much as 50% compared to a conventional cooling tower/central chiller system.
All evaporation and water consumed in the adiabatic process are external to the process loop, so process-fluid contamination and unwanted buildup in mold-cooling channels are eliminated.
The adiabatic saturation temperature (sometimes referred to as the thermodynamic wet-bulb temperature) is defined as the temperature obtained by an air-water vapor mixture if it becomes saturated with water vapor in an adiabatic process (ANSI/ASHRAE 1991).
The sensory analysis revealed that high quality mashed potatoes can be produced using an energy efficient, single step adiabatic process. The steam processed mashed potatoes were significantly more uniform, brighter and lighter in colour than the water processed samples and the heat transfer medium had no significant effect on the final product adhesiveness or cohesiveness.
An adiabatic process for the purpose of parcel theory means that the parcel of unsaturated air that is being lifted is expanding and cooling at a constant rate and does not exchange heat or moisture (mass) with its surroundings.
When we measure the variations of the fluid free surface in the state close to hydrostatic equilibrium (quasi-equilibrium-approximation of adiabatic process), we simultaneously determine the variations of equipotential surface.
The injection molding filling stage can be considered as an adiabatic process, depending on the value of a dimensionless number defined and used before [13, 14]
Calculated temperatures during the cold drawing process (adiabatic process) Material Value of the drawing relation in the first operation 0,6 0,55 0,50 0,45 Low carbon steel 60 69 80 93 Stainless steel 94 112 132 156 Aluminium 38 42 47 53 Duralumin 65 76 88 103 Table 2.
All of the evaporation and water consumed in the adiabatic process is external to the process loop, so process-fluid contamination--and unwanted build-up in mold-cooling channels--is eliminated.
