“…For instance, Yilmaz and Yilmaz analyze the economic costs of a refrigerated storage system against a natural one used to conserve potatoes. They conclude that modern refrigeration plants guarantee a return on investment in a short period (Yilmaz & Yilmaz, 2020). Valencia‐Flórez et al research the effect of different cold storage processes on two different potato varieties.…”

In order to maintain the quality of the potatoes over time, it is necessary to store them under certain storage conditions, which minimize losses both of quality and product, preferably without using chemical treatments. Conservation chambers consume a considerable amount of energy. Between 60% and 70% of the electricity consumed is used in refrigeration. Good insulation reduces the need for cooling the potato since its optimum storage temperature for consumption is around 4-7 C and relative humidity is 85%-90%. This research studies potatoes' cold storage process to minimize the cost in the product value chain and to ensure its competitiveness in the market. A model is developed to assess energy consumption and propose measures to reduce energy, environmental, and economic costs. All this to reduce their impact within the value chain of potato consumption.Practical Applications: In this case study, different energy efficiency measures applied to the cold storage of potatoes have been implemented: replacement or improvement of the performance of refrigeration equipment, insulation and infiltrations in the refrigeration chamber, control of the product entry temperature, thermal conditioning through free-cooling, improvements in lighting equipment, technical management, and supervision of facilities, and thermographic control. The set of actions implemented has allowed to obtain a reduction in energy demand, standardized through the developed reference line, by 16.41% compared to previous years.
