Description

Refrigerating apparatus Technical Field The utility model relates to the technical field of refrigeration equipment, in particular to refrigeration equipment. Background At present, along with the improvement of the living standard and purchasing power of people, the fresh-keeping requirement on stored foods is also higher and higher. The controlled atmosphere preservation technology is a technology with wider application range in the field of fruit and vegetable preservation, and by controlling various gas environmental parameters in a storage environment, the respiration of fruits and vegetables is inhibited, the metabolism process is delayed, the fruits and vegetables are in a dormant state, the decay and the deterioration are prevented, and the storage period is prolonged. The most important means of air conditioning is to reduce the oxygen concentration, the oxygen reduction system of the oxygen control film and the vacuum pump is adopted in the prior art, oxygen in the fresh-keeping chamber is pumped out by adopting the deoxidizing device, the oxygen concentration in the fresh-keeping chamber is reduced, the pressure in the fresh-keeping space is reduced, the requirements on the sealing performance of the pumping device and the refrigerator are high under the action of internal and external pressure differences, air outside the fresh-keeping space can enter the space through the air conditioning film, so that after the oxygen in the fresh-keeping space is reduced to a certain concentration, the pumping device continuously works, the oxygen is difficult to reduce, and a lot of articles are taken and placed every time, the fresh air in the fresh-keeping chamber is pumped out again, so that the energy required to be consumed is also a lot of low-oxygen state is formed, and the working efficiency is low.
