Design, Building and Study of a Small-size Portable Thermoelectric Refrigerator for Vaccines

For cooling small volume compartments, the thermoelectric systems have a number of advantages over the classic compressor refrigerators. Their priority is due to the active components in their design - Peltier modules which are chemically inactive, have no moving parts and do not practically need maintenance [1-2]. The thermoelectric cooling systems have the potential to meet the requirements for storing and transportation of vaccines and other medical solutions at low temperatures posed by the global pandemic of Covid-19. The electrical systems in the vehicles are excellent prerequisite for compatibility with the thermoelectric refrigerators requiring stable power supply.The aim of the present work was to design, realize and study a prototype of a small scale mobile thermoelectric cooling system for negative temperatures based on Peltier modules.
