This paper mainly describes the energy-saving technology research which is used in one brand of BC/BD-100DT models of direct cooling type refrigerator. The method is optimizing the evaporator in order to improve the temperature gradient distribution in the cabinet, also can achieve a supercooling of the liquid circu-lation and increase the unit refrigerating capacity through the optimization of the condenser, by optimizing the return pipe heat exchanger to ensure the accuracy of the refrigerant filling quantity, through reasonable arrange-ment of temperature controller to get reasonable compressor intermittent start-stop ratio etc. The energy consump-tion of the direct cooling type refrigerator reduced by 10% after the transformation with no change the compressor specifications and the cabinet’s structure. The energy saving technology research on the models of direct cooling type refrigerator has important significance to the design of the high efficiency and energy saving refrigerator.
