A study on the use of dual mixed refrigerant in a cascade dual mixed refrigerant cycle

Advances in Mechanical Engineering, 2017
In this article, a precooling cycle was used to reduce the power consumption and improve the heat transfer efficiency of a mixed refrigerant cycle. Propane precooling and mixed refrigerant precooling are two common precooling methods.

Alternative refrigerants and refrigeration cycles for domestic refrigerators [PDF]

, 1992
This project initially focused on using nonazeotropic refrigerant mixtures (NARMs) in a two-evaporator refrigerator-freezer design using two stages of liquid refrigerant subcooling. This concept was proposed and tested in 1975. The work suggested that the concept was 20% more efficient than the conventional one-evaporator refrigerator-freezer (RF ...
