Performance investigation of saturation cycle with natural working fluids.

Number: pap. ID41

Author(s) : LEE H., HWANG Y., RADERMACHER R.

Summary

A saturation cycle can improve a vapor compression cycle performance by reducing thermodynamic losses associated with single phase gas compression and isenthalpic expansion. As the use of natural working fluids becomes more important than ever due to the environmental concerns, natural working fluids such as propane and carbondioxide are applied to the saturation cycle in this paper. In order to approach the saturation cycle, a two-phase refrigerant injection technique is applied to the multi-stage cycle. The multi-stage cycles with different options are modeled, and their performances are evaluated under ASHRAE standard operating conditions and extreme operating conditions. In addition, a compressor realizing the saturation cycle is discussed.
