Evaporative cooling (EC) is an ancient technique that is usually suitable for hot and dry climatic conditions due to the potential of water vapor evaporation. In this study, three kinds of evaporative cooling systems such as direct EC (DEC), indirect EC (IEC), and Maisotsenko cycle EC (MEC) were locally developed at lab-scale. The performance of the systems was evaluated and compared for agricultural storage and livestock air-conditioning application in Pakistan. The experiments were performed for climatic conditions of Multan city (Pakistan) and the data were collected for hourly and daily basis. According to the results, it was observed that the DEC system has the ability to reduce the temperature of ambient air to an average of 8.5 °C. Whilst IEC and MEC systems were able to drop the temperature of ambient air to an average of 6.8 °C and 8.9 °C, respectively. As per the results, the DEC system remained behind to provide desired conditions for livestock and agricultural product storage applications due to excessive humidity. On the other hand, the IEC and MEC systems can achieve the desired conditions for livestock application, but could not provide feasible conditions for various fruits and vegetable storage. The study concludes that hybrid EC systems can be developed to provide desired conditions for a wide range of applications under varying climatic conditions.

蒸发冷却（EC）是一种古老的技术，由于存在水蒸气蒸发的可能性，因此通常适用于炎热和干燥的气候条件。在这项研究中，在实验室规模上局部开发了三种蒸发冷却系统，例如直接EC（DEC），间接EC（IEC）和Maisotsenko循环EC（MEC）。对系统的性能进行了评估，并比较了巴基斯坦在农业存储和牲畜空调方面的应用。针对巴基斯坦木尔坦市的气候条件进行了实验，并每小时和每天收集一次数据。根据结果​​，观察到DEC系统具有将环境空气温度降低到平均8.5°C的能力。尽管IEC和MEC系统能够将环境空气的温度平均降至6.8°C和8.9°C，分别。根据结果​​，由于湿度过高，DEC系统仍然落后，无法为牲畜和农产品的存储应用提供理想的条件。另一方面，IEC和MEC系统可以达到牲畜应用所需的条件，但不能为各种水果和蔬菜的存储提供可行的条件。研究得出的结论是，可以开发混合EC系统，以在各种气候条件下为广泛的应用提供所需的条件。但是不能为各种水果和蔬菜的存储提供可行的条件。研究得出的结论是，可以开发混合EC系统，以在各种气候条件下为广泛的应用提供所需的条件。但是不能为各种水果和蔬菜的存储提供可行的条件。研究得出的结论是，可以开发混合EC系统，以在各种气候条件下为广泛的应用提供所需的条件。
