| Summary: | In this paper, an experimental investigation is conducted on the heat transfer performance of evaporative condenser with parallel flow and counter flow. An experimental platform which test heat transfer performance of evaporative condenser is built, which can present theoretical and experimental study on the influence of condenser’s spray density and face velocity under the condition of parallel flow and counter flow. The results showed that: the total heat transfer increases with the increase of face velocity and spray density under the condition of parallel flow and counter flow, and finally reaches a maximum value; the heat transfer performance under the condition of counter flow is better than that of parallel flow. When the face velocity and spray density are 3.28 m/s and 0.057 kg/(m?s)respectively, the maximum value of total heat transfer is 616 W/(m2?K) for parallel flow, and 628 W/(m2?K) for counter flow. At the same condition, the mass transfer coefficient and EER of counter flow is better than that of parallel flow. |
