Development and evaluation of a low-cost evaporative cooling system for agricultural product storageShort Communication

Natesan Kapilan*, Vijay Kumar Patil

Agricultural products are highly perishable and, hence, we need to preserve these products after harvest. India is an agricultural country and, thus, the post-harvest storage of perishable agricultural products is important to reduce the gap between the demand and supply. Cold storage technologies have been developed and are used in India; however, these technologies are not popular in rural and remote areas due to the higher initial cost and the electrical energy requirement. Therefore, a number of low-cost technologies have been developed and, among these technologies, the evaporative cooling technology is gaining in popularity due to its simple design and lower initial cost. In this work, we have developed and tested a solar photovoltaic (PV) powered evaporative cooling system and used coconut coir as the cooling medium and compared the results with celdex pad. From this work, we observed that this system is an economical and efficient in reducing the temperature and increasing the relative humidity for the storage of agricultural products.
