Fresh farm produce of horticulture is stored at a temperature lower than its surrounding due to its high susceptibility to spoilage. Therefore, maintaining the freshness of these produce requires minimizing its chemical, biochemical, and physiological changes through precise control of temperature and humidity levels in the storage space. There are many methods to achieve the temperature of the ambience lower than its surrounding, but the most effective and economic method is evaporative cooling. The principle of evaporative cooling revolves around the transformation of a liquid into a gas or vapor state. It occurs when molecules within a liquid gain enough energy to break free from the surface and enter the surrounding atmosphere. This process is influenced by several factors, including temperature, humidity, surface area, and airflow. This review paper has been undertaken the investigations that address the nature of various types of Evaporative Cooling techniques which can be used for Cold Storage purpose, different types of materials used for cooling pads and how to increase the efficiency of cold storages based on evaporative cooling purpose. These studies have led us to better understanding of the evaporative cooling techniques. As a result, many cold storages have been developed based on evaporative cooling purpose to preserve fruits and vegetables. Various modifications were done in the construction of walls, structure of fans, methods of air circulation, etc. A zero-cost cooling system has proven to be highly effective for temporarily storing fruits and vegetables, specially in hot and dry climatic conditions. Evaporative cooled cold storages are not only lowering the storage temperature but also enhances the relative humidity within the storage area, which is crucial for preserving the freshness of the produce.
