Automatic control of active ventilation systems in agricultural products storage facilities

Abstract

The article recommends automatic control of active ventilation systems in agricultural product storage facilities. The search for rational solutions for ventilation, heating, and automatic control systems (ACS) that improve product storage quality and methods and means of storage is considered. As a result of the analysis of the requirements for air-cooling storage units that operate for no more than 25 days per annual storage cycle, it was proved that refrigerating arrangements that are based on the principle of operation of vortex energy separators - vortex tubes (VT) meet these requirements most fully. In terms of temperature effect, the VT is inferior to the expander by 1.3 ... 1.5 times, in terms of cooling capacity by 3.0 ... 3.5 times. Compared to the throttling process, vortex tubes, when operating in air, are about 30 times better in terms of temperature effect and 15 times better in terms of cooling capacity.

Theoretical foundations of electropulse impact on plant objects

“…It has been established that there are electrical charges on colloids and protein particles that determine the electrical properties of living cells of plant tissue and are the driving forces of metabolic processes [5,6,8]. For example, the protoplast of a cell has a negative charge.…”
