In hot and humid climates, the evaporative cooling system not works effectively. To reduce the relative humidity of inlet air, the reciprocating desiccant mesh (RDM) is introduced before the cooling tower. The cooling tower is fabricated as per the Merkel’s theory and RDM is placed before the cooling tower. Experiments have been conducted to compare the performance of normal and RDM cooling towers at different operating conditions. The results of this study indicate that the most favorable velocity and water flow rate of the RDM cooling tower are 1.8 m/s and 17.3 L/min, respectively. At this condition, the cooling effect of the RDM cooling tower is 1.6°C greater than the normal cooling tower. Further, the maximum effectiveness of normal and RDM cooling tower are 0.72 and 0.82, respectively. At last, this study recommends that the RDM cooling tower reduces water consumption as compared to the normal cooling tower due to the lower temperature of cold water.

在炎热和潮湿的气候中，蒸发冷却系统无法有效工作。为了降低进气的相对湿度，在冷却塔之前引入了往复式干燥剂网（RDM）。冷却塔是根据默克尔理论制造的，RDM位于冷却塔之前。已经进行了实验以比较普通和RDM冷却塔在不同运行条件下的性能。研究结果表明，RDM冷却塔的最佳速度和水流量分别为1.8 m / s和17.3 L / min。在这种情况下，RDM冷却塔的冷却效果为1.6° C比普通的冷却塔大。此外，普通和RDM冷却塔的最大效率分别为0.72和0.82。最后，该研究建议RDM冷却塔由于冷水温度较低，因此与普通冷却塔相比可减少水消耗。
