In hot and humid climates, the latent heat released by the primary air condensation can improve the heat transfer rate of the indirect evaporative cooling (IEC) system. However, it is harsh and unstable to obtain the latent heat only by reaching air dew point temperature. Moreover, the existing IEC and liquid dehumidification systems have a complex structure and large volume. Therefore, this paper developed and improved a novel device integrating the IEC technology and liquid dehumidification technology. The performance of the experimental system was researched under various conditions, including the dehumidification rate, primary air temperature change, wet bulb efficiency, and heat flux. The results showed that the dehumidification rate and the heat flux of the novel system under the different conditions were in the range of 0.92 g/s–1.58 g/s and 1.53 kJ/(m²·s)–2.42 kJ/(m²·s), which are 2.9 and 1.3 times higher than that of the IEC, respectively.

在炎热潮湿的气候下，一次空气冷凝释放的潜热可以提高间接蒸发冷却 (IEC) 系统的传热率。然而，仅通过达到空气露点温度来获得潜热是苛刻和不稳定的。而且，现有的IEC和液体除湿系统结构复杂，体积大。为此，本文开发并改进了一种集IEC技术和液体除湿技术于一体的新型装置。在各种条件下研究了实验系统的性能，包括除湿率、一次空气温度变化、湿球效率和热通量。结果表明，新系统在不同条件下的除湿率和热通量均在 0.92 g/s-1 范围内。² ·s)–2.42 kJ/(m ² ·s)，分别是IEC的2.9倍和1.3倍。
