With the rapid development of China's economy, refrigeration technology is increasingly widely used in various fields, among which the construction of cold storage is of great significance in food, medicine, chemical and other industries. According to the different functions and uses of cold storage, cold storage can be divided into distribution cold storage and productive cold storage. This article will introduce the differences and connections between these two types of cold storage in detail.
1. Definitions and Functions.
1.Distributive cold storage: Distributive cold storage is mainly used to store and regulate the distribution of goods from production cold storage or other ** sources. Its main function is to ensure the quality and safety of goods during storage and transportation, while reducing inventory costs and improving logistics efficiency. Distributional cold storage is generally equipped with a complete refrigeration system, insulation system, shelving system, etc., to meet the storage needs of different commodities.
2.Productive cold storage: Productive cold storage refers to the cold storage used in the production process, which is mainly used for cooling, refrigeration and freezing of raw materials, semi-finished products and finished products. The function of productive cold storage is to ensure the normal progress of the production process, ensure product quality, reduce energy consumption and improve production efficiency. Productive cold storage usually includes cooling room, refrigeration room, freezer room, etc., and the corresponding refrigeration equipment and insulation facilities are configured according to the requirements of the production process.
2. Differences. 1.Different uses: Distributive cold storage is mainly used for the storage and regulation of goods, while productive cold storage is mainly used for cooling, refrigeration and freezing in the production process.
2.Different scales: Distributional cold storage is generally relatively small in scale and has limited storage capacity;According to the production needs and process requirements, the scale of productive cold storage is large and small.
3.The refrigeration system is different: the refrigeration system of the distributive cold store is mainly aimed at the temperature control of the goods to maintain quality and freshness;In addition to solving the problem of temperature control, the refrigeration system of productive cold storage also needs to meet the special requirements of temperature, humidity and wind speed in the production process.
4.Different insulation materials: the insulation materials of distributive cold storage mainly consider the quality and energy saving of stored goods;The insulation materials of productive cold storage need to meet the requirements of the production process, and some also need fire prevention, explosion proof and other functions.
5.Different degrees of automation: The degree of automation of distributed cold storage is relatively low, and it mainly relies on manual operation and management;The degree of automation of productive cold storage is high, and it is necessary to realize the automatic control of the production process to ensure the stability of product quality.
3. Contact. 1.Both belong to the category of refrigeration engineering: both distributive cold storage and production cold storage are buildings that use refrigeration technology to achieve a low temperature environment.
2.Both need refrigeration system, insulation system and other supporting facilities: both need refrigeration system to ensure the maintenance of low temperature environment, and insulation system to prevent cold capacity loss.
3.There are energy-saving and environmental protection requirements: distribution cold storage and production cold storage should follow the national policy guidance on energy conservation and environmental protection, and adopt energy-saving refrigeration equipment and technology.
4.Follow the same refrigeration principle: Both distribution and production cold stores follow the principle of heat absorption and heat rejection of refrigerants to create and maintain a low temperature environment.
To sum up, there are certain differences between distributed cold storage and production cold storage in terms of use, scale, refrigeration system, insulation materials, degree of automation, etc., but they all belong to the category of refrigeration engineering, have the same refrigeration principle, and need to follow energy-saving and environmental protection policies. Therefore, in practical application, the appropriate type of cold storage should be selected according to different needs, give full play to their respective advantages, and improve the application effect of refrigeration technology.
