Abstract
A high efficiency 2 stage vapour compression cycle is developed for domestic refrigerator-freezer application. The 2 stage refrigeration system consists of two evaporators, two compressors, a condenser, two heat exchangers, expansion valves and a vapour-liquid separator. A new high efficiency cycle is selected depending on the arrangement of evaporators and compressors. The cycle simulation is carried with the refrigerant of R600a. It is found the 2 stage cycle with two serial evaporators and two parallel compressors gives the highest COP. COP of 2 stage cycle with two serial evaporators and two parallel compressors is more than 10.74% COP of 2 stage cycle with two parallel evaporators and two serial compressors.
