The results of numerical simulation of the temperature regime of a mixture of gas and evaporating water droplets in a closed thermally insulated volume in the presence of an internal heat source are presented. The internal heat source is represented by a monomolecular exothermic reaction with temperature dependence of the rate constant according to the Arrhenius law. The influence of changing the initial values of gas and droplet temperatures, mass fraction and droplet radius on the temperature regime is investigated. The possibility of stabilization of the reacting gas temperature by evaporating droplets and limitations of the thermostatting regime have been analyzed. Keywords: droplets, evaporative cooling, exothermic reaction, Arrhenius law, numerical simulation.
