| Abstract |
The new shape of louver-fin has been applied to a parallel flow condenser to enhance air-side heat transfer rate for an automotive air-conditioner. R-134a is employed as a refrigerant inside the flat tube of the condenser. This problem is of particular interest in reducing the geometric size of the automotive air conditioner. The effect of air flow rate on pressure drop as well as heat transfer in air side are studied in detail. Comparison of the performance is also made with that of a conventional parallel flow condenser, which is available in the market. The results obtained indicate that the total pressure drop through the present condenser is not changed, while the heat transfer rate is increased by 24% at high velocity of air flow, compared with those of the conventional condenser. The parallel flow condenser with a new shape of louver-fin could be reduced in size by 20% for the equivalent condenser capacity, compared with the conventional parallel flow condenser. |
