Large cold storage

Introduction of large scale cold storage:

A large cold storage is generally divided into indoor and outdoor type two:

1 outside the cold storage temperature and humidity: the temperature is +35 degrees C the relative humidity is 80%.
2 cold storage within the set temperature: fresh cold storage: +5 ~ -5 C; cold storage: -5 ~ -20 C; low temperature cold storage: -25
3 into the cold storage food temperature: L cold storage: +30 C; D, J grade cold storage: +15.
4 assembly type cold storage of the effective volume of the bulk of the nominal volume of about 69%, the storage of fruits and vegetables multiplied by 0.8 of the correction factor.
5 daily stock volume is 8 to 10% of the effective volume of the cold storage.

Two, large cold storage of the library

Large refrigerator with general color steel panel, rigid polyurethane foam or high-density polystyrene insulation material, base body has good rigidity, high strength, good insulation, flame retardant etc..
Small Refrigeratory library body generally adopts the eccentric hook type connecting internal wall embedded foam or solid, good sealing assembly and disassembly and convenient transportation, on-site construction and installation engineering quantity, labor saving, good quality, quick. Small cold storage with advanced refrigeration units, library capacity and refrigeration equipment matching the whole reason, cooling speed, energy saving, and all automated operation, safe and reliable operation. Small refrigeratory assembled widely applicable, cold storage temperature range of 5 DEG --23 DEG, special assembly refrigerator up to -30 DEG C, which can meet the needs of different uses, is suitable for various industries use.

Three, large-scale cold storage refrigeration equipment selection

Large cold storage refrigeration equipment is the heart of the refrigeration unit, small refrigeration unit models commonly used for general use of fluorine machine advanced refrigeration equipment, refrigeration equipment machine using fluorine refrigerant R22 refrigerant and other new small impact on the environment. Fluorine machine refrigeration equipment is generally small in size, low noise, safe and reliable, high degree of automation, wide range of application, suitable for rural small cold storage with refrigeration equipment.
Refrigeration unit, which is used for large scale cold storage, is often called a refrigeration unit, which is divided into a chiller unit and an air cooled unit. Large cold storage units in the preferred form, it has a simple, compact, easy to install, easy to operate, ancillary equipment and other advantages, such as the cooling equipment is also relatively easy to see.
Refrigeration unit is the heart of the refrigeration equipment, the common compression refrigerator has open, semi closed and fully enclosed. Fully enclosed compressor has the advantages of small volume, low noise, low power consumption, high efficiency and energy saving. It is the first choice for small cold storage models, mainly consisting of a fully enclosed type of air-cooled refrigeration unit, can be made like split air conditioning in the form of the wall hanging.
Now the market is relatively good full closed refrigeration compressor, the developed countries imported or joint venture refrigeration equipment, product quality is reliable, but the price relative to the domestic high above confidential 50%, more suitable for small-scale cold storage refrigeration equipment.

Four, large cold storage design points

Cold storage temperature is below 0 degrees (-16 degrees) small refrigeratory assembled on the ground (base plate) 10 channel beam overhead, the natural ventilation can be. Small cold storage, cold storage temperature 5~-25 degrees, cold storage board can be directly contact with the ground, but the ground to be flat. If the high wood can be placed in cold storage below the overhead to enhance ventilation; can also be placed in the refrigerator to enhance ventilation channel below.

Five, large-scale cold storage engineering design and installation recommendations

In recent years, the development of cold storage engineering construction is getting faster and faster, the understanding of the cold storage is also more and more in-depth, from building materials to a variety of cold storage equipment selection is becoming more and more mature. There are two common types of construction in cold storage engineering, one is the assembly type cold storage project, one is the construction of civil col
