The invention relates to an ultra-long-term freshness preserving system which can be applied to a refrigerator and installed in a refrigerating chamber of the refrigerator. The system comprises a freshness preserving box, an oxygen enriching membrane, a vacuum pump, a pressure sensor, a control plate and gas delivering pipes, wherein the oxygen enriching membrane is fixed in the freshness preserving box and connected with a gas sucking opening of the vacuum pump by the first gas delivering pipe penetrating through the wall of the freshness preserving box; an exhaust opening of the vacuum pump is led outside a box body for mounting the ultra-long-term freshness preserving system by the second gas delivering pipe; the pressure sensor is fixed to the first gas delivering pipe to sense the pressure in the freshness preserving box, and a signal line is connected with the control plate; and the control plate is connected with and controls the vacuum pump. The invention has ultrastrong freshness preserving function and can effectively improve the storing time of food stored in the refrigerator by being applied to the refrigerator; compared with the refrigeration of a common refrigerator, the invention is expected to be improved by 2-3 times. In addition, the invention can provide high-concentration oxygen for a room, has a plurality of advantages and practical values, and greatly improves the practicability and the healthy performance of the refrigerator.
