Air-conditioning freezer fresh-keeping system

Abstract

The invention discloses a fresh-keeping system of an air-conditioning freezer, which comprises an air-conditioning and fresh-keeping freezer set, wherein the air-conditioning and fresh-keeping freezer set comprises N air-conditioning freezers, and the fresh-keeping system is characterized by further comprising a nitrogen-making system and an air-conditioning and fresh-keeping integrated device, and the nitrogen-making system and the air-conditioning and fresh-keeping integrated device are both connected with the air-conditioning and fresh-keeping freezer set. In the fresh-keeping system of the air-conditioning freezer, the quantity of air-conditioning freezers can be selected according to the total loading capacity of fruits and vegetables, each air-conditioning freezer is provided with an independent refrigeration system, temperature inside the freezer can be adjusted, the requirements of storage temperature required by different fruits and vegetables can be met, classified storage can be performed according to types of fruits and vegetables, nitrogen consumption can be reduced, components and proportions, as well as parameters such as humiture and the like, of all gases inside the freezer can be controlled accurately, and the fresh-keeping system has a good marking prospect.

Description

technical field [0001] The invention relates to a fresh-keeping system, in particular to a fresh-keeping system for a controlled-atmosphere refrigerator. Background technique [0002] At present, the controlled atmosphere fresh-keeping refrigerator has become an important fresh-keeping equipment for fruits and vegetables. The controlled atmosphere fresh-keeping cold storage achieves the purpose of fresh-keeping insurance for fruits and vegetables by changing the composition and proportion of various gases in the storage. However, the modified atmosphere cold storage has the following disadvantages: 1. The volume of the modified atmosphere cold storage is huge, and it is difficult to change the volume of the cold storage after it is completed, and the volume cannot be selected according to the total load of fruits and vegetables, which is not suitable for the volume of equipment such as ships. Places with strict requirements; 2. The air-conditioned fresh-keeping cold storage...

Problems solved by technology

However, the modified atmosphere cold storage has the following disadvantages: 1. The volume of the modified atmosphere cold storage is huge, and it is difficult to change the volume of the cold storage after it is completed, and the volume cannot be selected according to the total load of fruits and vegetables, which is not suitable for the volume of equipment such as ships. Places with strict requirements; 2. The air-conditioned fresh-keeping cold storage cannot be stored according to the types of fruits and vegetables; 3. When picking up the goods in the warehouse, a certain amount of nitrogen needs to be consumed, so it is necessary to continuously replenish the loss of nitrogen; 4. It is difficult to accurately Control the composition and ratio of various gases in the library, as well as parameters such as temperature and humidity
