Description
Technical Field
The invention relates to the technical field of air-conditioned cold stores, in particular to a mobile precooling air-conditioned fresh-keeping integrated machine.
Background
At present, the air-conditioned cold store is also called air-conditioned cold store, and is the most advanced fresh-keeping storage method for fruits and vegetables at present. On the basis of refrigeration, the air composition regulation is added, and the respiration of fruits and vegetables is inhibited, the metabolism process of the fruits and vegetables is delayed, the freshness and commodity of the fruits and vegetables are better kept, and the storage period and the preservation period of the fruits and vegetables are prolonged by controlling the conditions of temperature, humidity, carbon dioxide, oxygen concentration, ethylene concentration and the like in the storage environment. The storage period of the air-conditioned storage can be prolonged by 0.5 to 1 time compared with the common refrigeration; the fruits and vegetables stored in the air-conditioned cold store are awakened from the dormancy state after being taken out of the cold store, so that the preservation period of the fruits and vegetables after being taken out of the cold store can be prolonged by 21-28 days, which is 4-5 times that of a common cold store. The freezing temperature of the refrigerator is generally between minus 5 ℃ and minus 30 ℃, the amount of stored frozen food is large, and the refrigerator is generally used for storing large-scale frozen food.
Aiming at the vigorous development of the current fresh market, the fresh demand is increasingly vigorous; this has led to the need for short-term transregional shipping of current fresh vegetables, meats, etc. For this reason, small mobile air-conditioned commercial cabins and mobile refrigerators have also been rapidly developed. However, conventional commercial air-conditioned and refrigerated storages exist separately, and although such a structure design is convenient for reducing the equipment cost, in some remote or less-demanded areas, fruits and vegetables and meat are often required to be delivered simultaneously, and when the fruits and vegetables are delivered separately, the delivery amount required by the corresponding delivery vehicles cannot be achieved, and if the fruits and vegetables are delivered separately, the transportation cost is increased. In addition, for some special fresh food materials, a freezing mode may be needed for storage in the early stage, and the food materials need to be thawed and preserved in an air-conditioned cold store after arriving at a destination, so that some manufacturers design commercial mobile fresh-keeping cold stores and air-conditioned cold stores to solve the problems at present.
However, the refrigerating space and the air-conditioned cold store space inside the commercial mobile refrigeration store which simultaneously has the refrigerating function and the air-conditioned cold store function are relatively unadjustable at present, and the main reason is that the refrigerating temperature in the refrigeration store is 18-33 ℃ lower than the temperature of the air-conditioned cold store; if design into space adjustable structure, this leads to sealed not enough between freezer and the air-conditioned cold store easily, and then leads to the freezer to keep warm the effect and descend easily, and the problem that the air-conditioned cold store temperature was low excessively easily appears, and then makes the fresh-keeping quality of this type of multi-functional portable freezer descend.
