Implementación de un prototipo-sistema para transporte de producto congelado, refrigerado a base de placas eutécticas recargables.

Abstract

In this research a prototype-system is developed to transport frozen product refrigerated based on plates with eutectic solution, where the freezing point, would be established at -33 °C. It began, performing a calculation of cooling power with respect to thermal insulation selected, environmental conditions, the thermal load, door openings, the heat provided by humans and volume. Also it took place, the design of the prototype system considering, energy, logistics and refrigerators factors in order to make the product commercially competitive, supported by information provided by market research previously conducted by the sponsoring company. In order to determine the required cooling capacity three periods of operation of the prototype system were established, the charging period of the eutectic plate would be the basis for obtaining the required cooling capacity, while the period of introduction of the frozen product and distribution period, of frozen product would deliver the amount of heat would enter into the system and would be stored by the eutectic plate. The only period in which the condensing heat medium would be ejected in the charging period of the eutectic plate and this value would be 9100.85 kJ. The selected insolation was poly-isocyanurate, dual vapor barrier, of 100 mm thickness with thermal conductivity coefficient of 0.026 W/°C·m, the cooling capacity during the charge was 590 W. It was documented, the manufacturing process system, in order that can be replicated in series and a plan weekly and monthly maintenance was established. The project cost was 6679.20 USD.
