Abstract: A refrigerating apparatus may include a main body having an interior space in which an article is accommodated, a door configured to open and close an opening of the main body, a compressor configured to compress a non-azeotropic mixed refrigerant, a condenser configured to condense the compressed non-azeotropic mixed refrigerant, a hotline provided at a contact portion between the main body and the door through which the condensed non-azeotropic mixed refrigerant flows, an expander configured to expand the non-azeotropic mixed refrigerant, heat of which is radiated by the hotline, and an evaporator configured to evaporate the expanded non-azeotropic mixed refrigerant to supply cold air to the interior space. According to such structure, even when the non-azeotropic mixed refrigerant is used, a function of the hotline to prevent dew formation may be normally performed with hot refrigerant.
