I, cold storage design
1, the type of cold storage
Cold storage is generally divided into three types: mechanical refrigeration, absorption and air conditioning. Mechanical refrigeration refers to mechanical equipment such as refrigeration through the compressor, lower cost, suitable for small commercial premises. Absorption type is the use of absorbent to absorb moisture, and then release heat to cool. Gas-conditioning refers to the preservation of freshness by controlling the composition and proportion of gases in the air.
2, cold storage temperature and humidity
The temperature and humidity of the cold storage is one of the key factors in the design of the cold storage. Generally speaking, the temperature of the cold storage between -18 ℃ to 5 ℃, humidity in about 70%. Different items require different temperatures and humidity, so these factors need to be considered in the design of the cold storage.
3, the capacity of the cold storage
The capacity of the cold storage needs to be determined according to the demand. Generally speaking, the capacity of the cold storage should be enough to store all the items that need to be stored, but also to consider the future expansion needs.
4, the structure and details of the cold storage
The structure and details of the cold storage also need to be considered. For example, the door of the cold storage needs to be insulated, and it is also necessary to consider whether it is necessary to install fire prevention and anti-theft facilities. In addition, the internal structure of the cold room should be reasonable so that items can be easily stored and removed.
Two, cold storage installation
1, cold storage construction license
Before installing a cold storage, you need to apply for a cold storage construction license. This license is issued by the General Administration of Quality Supervision, Inspection and Quarantine of the State, you need to provide some necessary data and information, such as building plans, design plans, equipment parameters and so on.
2, equipment procurement and installation
The equipment of cold storage includes refrigeration equipment, insulation materials, doors and so on. It is necessary to purchase and install these equipments according to the design program. Refrigeration equipment is the core of the whole cold storage, need to choose and arrange according to the design program.
3, cold storage insulation
Insulation is the core of cold storage design and installation. The selection and installation of insulation materials should be in line with relevant national standards and regulations. The quality and thickness of the insulation material determines the insulation effect of the cold storage.
4, cold storage ventilation and dehumidification
Cold storage needs to maintain a certain degree of ventilation and dehumidification, in order to maintain the humidity and quality of air. Therefore, it is necessary to install appropriate ventilation and dehumidification equipment according to the design program.
5, cold storage maintenance and maintenance
Cold storage maintenance and maintenance is very important to extend the service life of the cold storage and maintain its performance. Regular cleaning, maintenance and inspection of refrigeration equipment, insulation materials, ventilation equipment and dehumidification equipment are required.
The design and installation of a cold room requires consideration of several factors, including temperature and humidity, capacity, construction and details, among others. Before installation, you need to apply for a construction permit and purchase and install the equipment according to the design plan. After the installation is completed, the maintenance and upkeep of the cold storage is also very important.
