First of all, we should consider whether there are favorable conditions for building warehouses in terms of local supply of raw materials, materials, energy, water and other resources, as well as production cooperation (machine maintenance), freight transportation and sales market. Cold storage should be based on its nature of use, located in the origin, goods concentrated areas or major consumption areas, to ensure the reasonable flow of loaded goods. In the overall layout, it should not be arranged in the city center and the upstream of its drinking water source, but should be chosen as far as possible near the town.

Step 2 transport

It is necessary to consider the convenient land and water transportation conditions near the site to facilitate the transshipment of goods. Large and medium-sized cold storage requires railways to pass nearby, especially ship docks, which are convenient to connect with nearby enterprises and shorten the length of special railway lines. When selecting a site, you should know the possibility of building a dedicated line from the relevant departments and obtain the certificate that it can be connected. Small and medium-sized cold storage is mainly transported by road, so the location should be as close to the road as possible to shorten the length of new roads outside the warehouse. Bridges and tunnels should be avoided as much as possible.

3. Regional environment

There should be a good sanitary environment around the cold storage site, and the development plan of local urban construction should be considered when selecting the site, so as to understand the sanitary condition of the surrounding environment and the possible pollution trend in the future. The location of the warehouse should be far away from factories and mines that produce harmful gases, smoke, radioactive substances, dust, odor or seriously pollute groundwater, and should be located in the upwind area of the industrial zone as far as possible, and should be located upstream of the discharge port of the sewage treatment plant. Reservoir site selection should not be located in the lower reaches of polluted rivers or near infectious disease hospitals.

4. Topography and geology

When selecting the site, the topography, geology, flood level and groundwater level of the reservoir site should be carefully investigated or necessary investigation and analysis should be made. The site selection should be based on the principle of saving land, occupying less cultivated land and not occupying fertile land, and making use of wasteland and sloping land as much as possible, instead of unilaterally emphasizing the flatness of the reservoir site.

5. Water source

Cold storage is an enterprise with large water consumption, and water source is one of the important conditions for determining the storage site. Therefore, there must be enough water near the reservoir. Generally, river water or deep well water is used as water source. If the reservoir is located with sufficient water, primary water can be used for cooling water, but circulating water is still used in most cases. Small cold storage uses tap water for recycling without natural water.

6. Power supply

The power supply of cold storage belongs to the second kind of load, which needs reliable and stable voltage power supply. Efforts should be made to shorten the distance between newly-built high-voltage transmission lines and power supply connection points. If there is no power supply nearby, you should generally choose another library site, regardless of self-built power generation equipment for power supply. Therefore, it is necessary to know the local power supply situation and line power supply situation in detail when selecting the site, and Bing should contact the local power department to obtain the power supply certificate.

7. Others

Need to know whether there are heat sources such as thermal power plants nearby, whether there are residential areas, public living facilities, primary and secondary schools nearby, and whether it is convenient for workers to go to work.
