The article touches upon the problem of conditions and ways of storing potatoes at large harvesting fruit and vegetable storehouses. There are the methods of vegetable storage in bulk and in containers. Various air exchange systems are considered for natural food storage under ambient temperatures, artificial storage using refrigerators and heating devices and combined types. There has been proposed the advanced air ventilation system in the storehouses for containerized goods. The new ventilation system allows improving the air mass circulation system throughout the storehouse providing individual air supply to each container, regulating the local air supply and ventilation of the container, if necessary. This ventilation system generally reduces losses of fruits and vegetables by 12–15 % due to slight increasing electrical energy consumption by 2–4 % and the reconstruction of the storehouse. The use of the PC control of climatic parameters (temperature and humidity in the storehouse), the air exchange system (local resistance to regulate the flow rate and air velocity) and operational control of the system with a combined version of the work will not only further reduce production losses, but also significantly save electrical energy.
