Thermoelectric modules, also known as Peltier modules, are used for cooling small devices and also, according to
literature, in refrigeration. They can be an alternative to conventional refrigeration systems based on the use of
compressors chillers powered by AC power. Peltier modules are powered by direct current (DC), which allows to power
them directly supply by photovoltaic modules.
In this paper operation of thermoelectric module used for cooling experimental room of cubature 0.125 m<sup>3</sup> is
presented. The study involves investigation of temperatures achieved on the cold and hot sides of module and inside the
experimental room depending on the values of module supplying current. These studies provide an introduction to the
assessment of the influence of different methods of heat removal on the hot side of thermoelectric module on cooling
efficiency of whole system.
