Energy efficiency assessment of alternative power supply system for isothermal wagon for live fish transportation

Abstract

The research object is the power supply system of isothermal car for live fish transportation. The aim of the work is to assess the reduction of total energy costs when supplying electricity to an isothermal wagon for live fish transport by alternative sources in the form of wind turbines and solar panels. It is proposed to use centrifugal and centripetal wind turbines with vertical rotor as sources of mechanical energy of the aeration system of water tanks with live fish, and flexible solar panels placed on the roof of the isothermal wagon and thermoelectric converters as additional sources of electrical energy. When calculating the total energy costs for supplying electric power to the isothermal wagon for live fish transport, data from the literature sources were used. According to the calculations, by adding alternative sources of electricity to the existing isothermal wagon power supply system for fish transport, the total energy costs can be reduced by more than 30%.
