As a coolant, make it evaporate under low pressure and mechanical conditions to absorb the heat in the storage, so as to achieve the purpose of cooling.Requirements for refrigeration equipment in quick freezing warehouse: the strict sealing of quick freezing warehouse is obviously different from that of ordinary quick freezing warehouse. Therefore, how to seal the refrigeration equipment is the key. First of all, all through wall pipelines must be equipped with sleeves, the frost flushing water return pipeline must be equipped with U-shaped bend water seal, and the main frost flushing and return pipeline outside the warehouse shall be equipped with air filling port to prevent the gas in the warehouse from being pumped out of the warehouse by negative pressure. In addition, due to the good sealing of the quick freezing warehouse,BrestHow much is the fruit preservation cold storage, the set fluctuation range of the warehouse temperature should not be too large to prevent excessive positive and negative pressure from damaging the warehouse body.Brest, because it has higher strength when connecting in this way.Tchollire,In order to ensure the safety of construction and cold storage operation the span between the top storage plate supports (lifting points) shall comply with the following provisions: the polystyrene top storage plate (mm thick) has a very large span of M, and the polyurethane top storage plate (mm thick) has a span of m.Different food processing technical processes for the construction of cold storage are combined with local urban planning. The construction of cold storage is the design requirements and construction of cold storage, but also ensures its transportation facilities: within the construction scope, a reasonable overall layout, saves land and reduces costs.During the use of cold storage, attention shall be paid to the collision and scratch of the storage body to avoid the depression and corrosion of the storage plate, which will seriously reduce the local thermal insulation performance of the storage body.

When outdoor air enters the cold storage body, it will not only increase the cold consumption of the cold storage, but also bring water into the warehouse. The condensation of water will lead to the building structure, especially the heat insulation structure, being damaged by moisture and freezing. Therefore, a moisture-proof and heat insulation layer should be set to keep the cold storage board building moisture-proof and air-proof performance and good sealing.The air-conditioned storage is relatively fast. It usually reaches the required temperature, a few minutes faster and an hour slower. Of course, according to the temperature of the environment the amount of inventory and the temperature in winter and summer, refrigeration is also divided into air cooling,BrestCold storage installation materials, water cooling, direct cooling and simple cooling. Different refrigeration is fast and slow, but most small refrigerators are air-cooled, The market share is about %.There are many application scenarios of cold storage, which are different. For a long time, it provides various cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, on-site settlement, honest operation, and has offices all over the country for long-term cooperation. Different purposes, functions and designs, so what needs to be understood in cold storage design?install,The height of the warehouse, refrigeration equipment, transportation and stacking conditions. The selection of insulation board is very important for Guangdong cold storage. At present, the vast majority of cold storage use polyurethane insulation board. What are the characteristics and advantages of polyurethane insulation board?It is equipped with temperature compensation to automatically adjust the water temperature. The water temperature of ultrasonic atomization is - degrees. If our humidifier is connected with the warehouse, there is no temperature compensation, the water temperature is lowWhen installing the polyurethane insulation board, the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.

The drainage at the outlet of the cooling fan, the drainage of the volatile cooler and the road drainage of the refrigerated warehouse storing food or drinks shall not be immediately connected with the sewage and wastewater pipeline system software, but indirect drainage shall be adopted. For the flushing (thawing) water drainage of each layer in the double-layer cold storage, an exhaust valve equipment shall be set in front of the main riser for flushing (thawing) water drainage.Encyclopedic knowledge,When using the cold storage, try to keep the ground clean and professional cold storage installation,With the continuous development of cold chain industry, the construction scale of logistics cold storage is expanding, and the construction quantity is also increasing. According to statistics, at present, the performance growth rate of cold chain is maintained at % ~ %; This leads to the increasing demand for logistics cold storage. In the design of logistics cold storage, people have strengthened the optimization and transformation of the existing cold storage on the basis of the design and construction of the new cold storage so as to ensure its functions in product freezing, refrigeration, insurance and so on.Polyurethane refrigeration board uses light polyurethane as the internal material of refrigeration board. The advantage of polyurethane is very good heat insulation. The exterior of the cold storage is composed of SII, PVC color steel plate and stainless steel plate. The advantage of this is that it can prevent refrigeration, because the temperature difference inside and outside the board is large, and the temperature will disperse, which makes refrigeration more energy-saving and improves the working efficiency of refrigeration.BrestThe water tank is designed to be separated from the machine body and is double-layer. It will not drip due to condensation caused by internal and external temperature difference. It can be interlocked with the refrigeration system, that is it will not be humidified during refrigeration to prevent serious frosting of the fan.Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Cold storage fault phenomenon: dryer does not operate, compressor line is disconnected, fuse is blown, thermal relay acts, high voltage switch acts, line is falsely connected or loose fault phenomenon: it stops in a short time after drying, ambient temperature is too high, condenser is blockedFor the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of ~ mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.
