2. Cold storage design considerations
1, the volume of the cold storage The size of the cold storage should be based on the highest amount of perennial storage of agricultural products to design.
The capacity is based on the storage of products in the cold storage must occupy the volume of stacking, plus the rows of aisles, stacks and walls, the space between the ceiling and the gap between the packaging and so on calculated. Determine the cold storage capacity after this, and then determine the length and height of the cold storage.
2, cold storage site selection and preparation of cold storage design, but also consider the necessary ancillary buildings and facilities, such as work rooms, packaging and finishing rooms, tool storage and loading dock. According to the nature of the use of cold storage can be divided into distribution of cold storage, retail cold storage, production cold storage three categories.
Productive cold storage built in the source of more concentrated production areas, but also consider the convenience of transportation, and market links and other factors. Cold storage should be surrounded by good drainage conditions, the water table should be low, the best cold storage under the compartment, and to maintain good ventilation, to maintain a dry cold storage is very important.
3, the choice of cold storage insulation material cold storage insulation material selection must be adapted to local conditions, both good thermal insulation performance, but also economic and practical. The structure of the modern cold storage is being assembled cold storage development, made of cold storage components including moisture-proof layer and insulation layer, to do on-site assembly, the advantage of its construction is convenient, fast, and can be moved, but the cost is relatively high.
3. Matters to be noted in the installation and use of cold storage
With the gradual rise in the trend of cold storage cold chain industry, more and more people want to build a cold storage, to get more benefits.
In fact, building a cold storage is not something that can be established in three days. To build a qualified, standards-compliant cold storage, what are the aspects that need attention? In fact, in addition to professional installers, business insiders also need to understand some basic cold storage common sense.
1, the site of the cold storage installation should be in a smooth, convenient transportation; (if the local fruit farmers business, it is best to be installed near the source of the fruit); 2, the cold storage installation of the library board splicing needs to be tightly spliced to ensure that the sealing; 3, the cold storage will be drained when the operation of the drain, the drainpipes should be installed to be able to circulate the place; 4, the cold storage door needs to be installed around the collision bar, to prevent damage to the door of the library to prevent the impact of damage to the door, and play a 5, cold storage should be installed in the emergency lighting, alarm devices, safety channels, to facilitate the sudden *** situation can be self-help or alarm for help. 6, reasonable design of the cold storage room, such as: cold storage room, freezer room, machine room, aisle, transport platform, etc.; 7, cold storage should be established indoors, to avoid high temperatures, refrigeration effect is poor, if you must be outdoors, you should establish a sunshade; 8, the electric wire should not be outdoors, because the long-term exposure to the sun and wind is prone to cause line deterioration, short-circuits and leakage and other accidental situations.
4. What are the precautions for the use of cold storage industrial refrigeration equipment
These are to ensure heat dissipation.
In order to ensure the normal work of the refrigeration equipment, in the use of the need to pay attention to the following points, the panel switch on the electronic control box can be placed in the position of the "on", and regularly remove the refrigeration unit with a soft brush. In addition, do not dismantle the refrigeration unit and electric cavity components, the chiller should not be stacked in front of the items, so as not to affect the refrigeration effect.
At the same time, do not feel free to connect the power supply of other electrical appliances in the control cabinet. Industrial refrigeration equipment is not as good as the daily refrigeration equipment so well maintained, the need for professionals to constantly check and test, one side affects the efficiency of industrial production; 5, observe the operation of the control cabinet or observe the temperature table changes, strictly grasp the amount of storage, the daily amount of storage should be no more than 15% of the total storage capacity ; 4, refrigeration compressor set of protection have been set in advance, do not need to be adjusted: 1, the user of the cold storage only to be The user of the cold storage only needs to close the gate knife in the electric control box, often check and confirm that the voltage of the power supply line meets the requirements, and the voltage should be 380V±10%, the ash on the radiator, and prohibit the electrical parts and the computer control cabinet from contacting water, so as to avoid damage.
In addition, it is necessary to regularly observe the evaporator frost melting situation. 6, other parameters have been set without adjustment.
2, but also regularly clean the condenser of the refrigeration unit, which is the key to effective refrigeration, three-phase four-wire or five-wire; 3, the refrigeration compressor unit around the refrigeration compressor unit do not pile up debris around the refrigeration unit of the cold storage is strictly prohibited to pile up objects and away from the source of heat, in order to facilitate the flow of air and the full dissipation of heat.
5. What are the precautions for the use of cold storage industrial refrigeration equipment
Cold storage refrigeration unit is strictly prohibited around the stacking of objects and away from the source of heat, in order to facilitate the flow of air and fully dissipate the heat, and regularly remove the refrigeration unit with a soft brush, the radiator on the ash.
These are to ensure that the heat dissipation. In order to ensure the normal work of the refrigeration equipment, in the use of the following points need to be noted: 1, the cold storage users only need to close the gate in the electric control box, the electric control box panel switch key is placed in the "open" position that is, other parameters have been set up without adjustment.

Cold storage using industrial refrigeration equipment is very extensive, the correct use and maintenance is to ensure the key to safety.
6. Cold storage design considerations are what
The formation of a perfect cold storage design is not an easy task, he needs to carry out thorough consideration and measurement in order to formulate, the process of design, the user's use of the demand and the installation of the location and other factors need to be taken into account to ensure a better fit for the user's future use of the needs of the user.
Reduce failures and improve efficiency. Points to consider in the cold storage design plan include the following: 1, the volume of the cold storage The size of the cold storage should be based on the highest amount of perennial storage of agricultural products to design.
The capacity is based on the storage of products stacked in the cold storage necessary to occupy the volume, plus rows of aisles, stacks and walls, the space between the ceiling and the gap between the packaging and so on calculated. Determine the cold storage capacity after this, and then determine the length and height of the cold storage.
2, cold storage site selection and preparation Cold storage design should also consider the necessary ancillary buildings and facilities, such as work rooms, packaging and finishing rooms, tool storage and loading dock. According to the nature of use, cold storage can be divided into distribution of cold storage, retail cold storage, production cold storage of three types.
Productive cold storage built in the source of more concentrated production areas, but also consider the convenience of transportation, and the market and other factors. Cold storage should be surrounded by good drainage conditions, the water table should be low, the best cold storage under the compartment, and to maintain good ventilation, to maintain a dry cold storage is very important.
7. Some of the preservation of cold storage precautions what it
1, preservation of cold storage sealing parts of the maintenance, due to the preservation of cold storage is made of a number of pieces of insulation board spliced together, so there is a certain gap between the boards, the construction of these gaps will be sealed with a sealant, to prevent the entry of air and moisture.
So in the use of some of the sealing failure parts of the timely repair. 2, fresh cold storage equipment, electrical equipment should be avoided moisture, so as to avoid leakage caused by electric shock accident.
3, often check and confirm whether the voltage of the power supply meets the requirements, the voltage should be 380V ± 10% (three-phase four-wire). When the cold storage equipment is not used for a long time, the total power supply of the cold storage should be cut off, and make sure that the cold storage equipment is not damp and polluted by other substances such as gray.
4, such as filming test, can also be carried out below, also brings great convenience. 5, all refrigerant pipe insulation pipe must be wrapped with wrapping tape, over the floor with steel casing.
6, regularly check the refrigeration unit's connecting tubes, valve parts on the connecting tube is firm, whether there is refrigerant leakage (general leakage will appear in the place of oil). The most practical way to check the leakage is to use a sponge or soft cloth dipped in detergent, rub the foam, and then evenly coated in the place where the leakage is to be checked, and observe for a few minutes.
If there is a leak, bubbles will appear. Mark the leakage place, and then do the fastening or gas welding treatment (by professional refrigeration staff to carry out repair operations).
