Method for Refrigerators Efficiency Increasing

[摘要] The article shows that in condenser-type domestic refrigerators the condenser is one of the main parts of the refrigeration system where the refrigerant (freon) compressed by the compressor condenses from the vapor state to the liquid. The condensation process is an exothermic process, i.e., the condensation of steam generates thermal energy. The condenser is heated and, to perform the refrigeration cycle, this heat must be removed from the refrigeration system. Heat removal is carried out in household refrigerators due to the natural circulation of ambient air around the condenser, which must have a significant heat-reflecting area to do this. Although the condenser is most often made of thin tubes that occupy almost the entire rear wall of the refrigerator, the cooling process is not effective enough. A new method for the condenser cooling is proposed which will improve the efficiency of the condenser and household refrigerators as a whole.
