Diseño y análisis energético de un sistema de refrigeración autónomo para el traslado de vacunas

Abstract

Vaccination is one of the most important methods of promoting health in the world, to preserve the effectiveness of these pharmacological products the operation temperature range in between 2°C and 8°C. Thermoelectric coolers are solid state devices that convert electrical energy into thermal energy, although they are destined to small capacities of cooling which are of the order of 2 to 250 watts, they are optimal for the cooling of portable systems. This paper describes the design and energy analysis of a portable system for the transfer of vaccines in rural areas, which will be powered by solar energy. The design integrates the choice of thermal insulation, geometry and operation of the system. Energy analysis allows to obtain the necessary energy to maintain the vaccines at temperatures between 4 ° C and 6 ° C, from the estimation of the thermal loads, and thus the election of the photovoltaic system best suited to ensure the necessary autonomy time.
