Desarrollo y control de un contenedor frigorífico para el transporte de alimentos en vehículos livianos

Abstract

The objective of this work was to develop a refrigerated container for the food transportion in light vehicles and to control the temperature, according to the refrigeration needs for the different types of food transported food. It starts with the analysis of the refrigeration equipment used by food deliverers for the transport and orders delivery. In the design phase, the container capacity is established, the appropriate materials for its construction are chosen and the plan is drawn up with the help of design software. In the construction stage, the container is drawn, folded and assembled, taking care of details such as airtightness, surface finish and thermal insulation. A microcontroller and programming in Arduino software with C language are used for temperature control, and a 12Vdc power supply is applied. As a result, the operation of the refrigerated container with Peltier plates, for food transport, is obtained with considerably low performance and efficiency due to the fact that significant power consumption is required for the work of the forced convection heatsinks. The high load required to operate the system would cause premature wear of the vehicle battery. Further experimentation is recommended to improve the performance of the Peltier cell cooling system.
