The constrained convection condenser is generally utilized as a part of refrigerator. The condenser, and compressor are typically set in a rear the refrigerator bottom. Both air inlet and outlet grilles are introduced on the cooler back panel and separated from condenser and on its same side. The deviation makes most airflow go through piece of condenser close to back panel. Then, airflow tends to go through free gap amongst condenser and its nook because of littler weight drop and has little contact with condenser, in this way trading less heat. An outer foam ring and central foam were applied to improve airflow distribution around a spiral condenser (SC) in this paper. The external foam was situated around the downstream part of spiral condenser to block of the free gap between spiral condenser and it’s enclosed. The central foam was installed in the upstream part to obstruct the centre stage of spiral condenser. More airflow was directed to pass through and exchange heat with spiral condenser, causing decrease in condenser middle and outlet temperatures respectively. The consolidating temperature decrease contributed to less refrigerant heat relocation into evaporator from condenser during compressor-off period, and thus compressor-off time expanded by 3.15%. Finally, refrigerator energy consumption was decreased by 4%.
