The paper proposes a model of a thermoelectric cooling chamber for medical purposes, which takes into account the thermal resistance and heat capacity of all the main elements of its design, ensuring that the simulation of the chamber cooling process is close to the actual conditions of its operation. A mathematical method of simulating the characteristics of the non-stationary cooling process of such a chamber is described, based on the solution of quasi-stationary heat balance equations at the boundaries between the main elements of the refrigerator model in combination with the solution of a stationary boundary value problem for finding the distribution of temperature and heat flow in thermoelectric legs. An algorithm and a computer tool have been developed to calculate the characteristics and parameters of the chamber cooling in the non-stationary mode of its operation. The computer program allows analyzing the influence of the design of thermoelectric modules and their power supply mode on the efficiency of the chamber cooling process, and using the obtained results to improve the design of TE modules and optimize their operating modes.
