Single and double row parallel-flow condensers had been used in the refrigerated display cabinet. This system was compared to the refrigerator system which used fin-and-tube condenser. This study show that the compressor average power consumption in a cycle was minimum when refrigerant was charged 550g

650g and 800g respectively in the refrigerator systems which used single

double row parallel-flow and fin-and-tube condensers. The system with double row parallel-flow condenser consumed the least power among the three systems

and the system with single row parallel-flow condenser was almost the same with the system with fin-and-tube condenser. In the air side

parallel-flow condensers’ performance was better than the fin-and-tube condenser. The single and double row parallel-flow condensers only have a quarter and a half volume of the fin-and-tube condenser in the experiment

which indicates that parallel-flow condenser will be a good solution for the insufficient heat exchange capacity in the harsh environment and reduction of the cost when applied in refrigerator.
