fresh-keeping storage or cold storage room is to maintain the original quality and freshness of some agricultural products to the
greatest extent for a long time, that is, fresh agricultural products, after a period of fresh-keeping storage, are still just picked
or close to fresh. Freshness and quality at the time of picking.

The temperature is constantly changing with the seasons of the year and the time of the day. In the seasons of conventional cultivation
and harvesting of most agricultural products, the temperature is relatively high, and the temperature varies greatly day and night, which
is extremely unsuitable for fresh-keeping and storage of products. Many simple methods are to find a place with a relatively low and stable
natural temperature to store agricultural products to extend the fresh-keeping period of the products, such as caves, crypts, shady places,
etc. These methods cannot control the temperature arbitrarily, the fresh-keeping effect is poor, and the fresh-keeping period is also short.
relatively short. The final solution is to manually manufacture a relatively stable low temperature condition, that is, through mechanical
equipment and electronic instruments, the temperature can be controlled artificially within a certain range. Common cold storage , is such a
facility.
