A Thermoelectric Refrigerator for Short-Term Storage and Transportation of Biological Materials

The design of a thermoelectric refrigerator for short-term storage and transportation of biological substances based on a cascade thermoelectric battery (TEB) is assessed. One feature of the device is the ability to store several types of biological objects with different temperature conditions simultaneously. Relationships between changes in temperature at monitoring points within the device over time at different TEB supply currents are addressed. Organization of the required temperature regime for storage of biological materials can be achieved using standard manufactured TEB.
