Refrigeration equipment

The utility model relates to refrigeration equipment. The refrigeration equipment comprises a box body, a refrigeration chamber and an air duct assembly. Wherein the refrigeration chamber is arranged in the refrigerator body, and the refrigeration chamber comprises opposite side walls and a back wall connected with the side walls. The air duct assembly is arranged in the refrigeration chamber and comprises an air supply duct, an air return duct and a plurality of air supply and return units. The multiple sets of air supply and return units are arranged in the direction from the bottom to the top of the refrigeration equipment, and each set of air supply and return unit comprises an air outlet duct and a first air return opening. The air outlet duct is provided with an air outlet. The air supply duct communicates with the refrigeration chamber through the multiple air outlet ducts and the multiple air outlets. The air return duct communicates with the refrigeration chamber through the multiple first air return openings. According to the arrangement of the structure, the refrigeration efficiency can be improved, meanwhile, the refrigeration equipment can achieve circulation of the cooling capacity at different heights, and then the uniformity of the temperature in the refrigeration chamber is improved.
