The idling of a cooling hybrid system in winter time in Cluj county

Abstract

The renewable energy sector is a very important domain nowadays that is significantly exploited. To follow the actual trend, a cooling hybrid system made of a solar thermoelectric cooler was built. Experiments were conducted with it in the case of idling in all kind of winter weather conditions of the Cluj-Napoca city (snow, clouds and sun). The analysis confirmed that in the presence of snow, solar irradiation’ value is very small and the cooler cannot work if the electric energy wasn’t previously stored in the battery. In the other two cases, there are no problems. Also, the temperature registered during idling showed the system can work as both cooler and freezer, depending on the need.
