Study the performance of a domestic refrigerator with dual-loop cycle flow condenser and comparison with wire-on-tube condenser

الملخص EN

This paper presents an experimental investigation into the performance of domestic refrigerator system with two different types of condensers, novel design of dual-loop condenser and the conventional condenser.

The geometrical configuration considered in this study is representative designing and manufacturing of novel type of dual-loop cycle condenser and compared with typical condenser.

The experiments were conducted with a refrigerator designed to work with HFC134a, under no load and with different loads as (1.5, 3 and 12 litters of water).

The results showed that the dual-loop condenser decreases the work done by the compressor by about (1.951% to 5.257%).

Also, the effects of shape change of the condenser can be reducing the pressure drop as result of reduction the frictional loss where can rotate the flow without restriction to the flow in the dual-loop condenser.
