The invention discloses enhancement type energy-saving refrigerating equipment which comprises a compressor, condensers, an expansion valve, an evaporator, an air cylinder set, a sealed container, a generator and other main components. The air cylinder set is composed of multiple air cylinders. The air cylinders and the sealed container are wrapped by a thermal insulation material. A heater is mounted on the air cylinders and the sealed container and used for heating the air cylinders and the sealed container, and the temperature of the air cylinders and the sealed container is equal to or higher than the outlet temperature of the compressor. The compressor, the air cylinders and the sealed container are mounted in a thermal insulation box, and heat dissipated by the compressor is absorbedby the air cylinders and the sealed container. Each air cylinder is provided with the corresponding independent condenser. A refrigerating agent sequentially passes through the compressor, the air cylinder set, the condensers, the expansion valve and the evaporator and finally enters the compressor from the evaporator, the air cylinder set can utilize atmospheric pressure in the sealed containerfor acting power generation, consumed power of the compressor can be compensated, and therefore electric energy can be saved.
