The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example, the cold storage that only circulates vegetables can only build a fresh-keeping cold storage, while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage, it should be determined according to the type, quantity, frequency, cycle, whether to use shelf stacking and so on. For example, for fruits and vegetables packed in cartons, the storage capacity of -kg per cubic meter can be referred to, and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..The ground insulation of small, medium and large cold storage is different, which is closely related to the purpose, storage products and size of cold storage. Kuhua refrigeration reminds: ground insulation must be done otherwise the temperature in the cold storage often fluctuates frequently due to poor insulation performance, which affects the quality of stored goods. So, what is the difference between the ground insulation of small, medium and large cold storage? How to do better?Sania,The ground should be flat and not uneven. If the ground is uneven, the ground of the warehouse must be leveled before the cold storage can be built and installed.Secondly, since the cooling of the compressor is not continuous,SaniaHow much does it cost to install a small cold storage, the multi work operation at night can be selected if possible. When working at night, the external temperature is low, the cooling water temperature is reduced, and the condensation pressure and condensation temperature are reduced. The cooling capacity of the sampling system, coupled with the equal role of the cold storage board, reduces the power operation of the compressor and achieves the purpose of energy saving.Kalush,Indirect cooling is that the air in the warehouse is pumped into the air cooling device by the blower. The air is absorbed by the evaporation pipe circling in the cooling device, and then sent to the warehouse for cooling. The advantages of air cooling are rapid cooling, reliably and accurately. Special connectors shall be used for wiring and can bring harmful gases such as carbon oxide out of the warehouse during storage.All wiring shall be neat. All switches and keys shall be opened and closed sensitively, and power protection shall be provided for the box and each power branch.The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, pay attention to it. If the machine is abnormal, it needs to be checked in time.
Cold storage has good fire and flame resistance. After adding flame retardant, polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be closed as a whole after fire prevention treatment to form non combustible products.Generally speaking, the logistics cold storage project will be equipped with supporting electric cold storage doors and electric rolling shutter doors in the design of cold storage doors, rather than the traditional push-pull cold storage door configuration. Kende refrigeration said that this is because pushing and pulling the refrigerator door is not conducive to the locking of the refrigerator temperature, which is easy to cause serious loss of refrigeration capacity and is not suitable for logistics refrigerators that often go in and out.Now let's analyze the production and use requirements of the cold storage. There is no condensation in the cold storage. Condensation in the cold storage or in the insulation layer is harmful. During the drying process of the new wall or under winter conditions, when the water vapor with high indoor temperature migrates outdoors,SaniaPharmaceutical cold storage price, it is impossible to condense in the wall due to the obstruction of the cold storage.Price,The physical properties of polyurethane insulation board are relatively good, which can meet different needs. The polyurethane insulation board is also strict in the selection of materials. It is a special product manufacturing enterprise integrating R & D, and service. It has long been specialized in cold storage installation, cold storage installation, cold storage construction fruit preservation cold storage and medical cold storage. It improves the overall performance of the polyurethane insulation board and enables the polyurethane insulation board to work for a long time, descaling and air discharge in the refrigeration system of the warehouse.The door of the combined cold storage is not tightly closed. Please adjust the distance between the hinge on the door and the door lock and the storage body.
Cold storage has good water tightness. Polyurethane rigid foam has low water absorption, good permeability to water vapor, foam holes, disconnected and closed porosity of more than %. It is a dense microporous foam material, which is more dense than air surface, and is not easy to permeate. It belongs to hydrophobic materials.Which one is better,The foundation of cold storage is affected by low temperature, the ground will be broken and the whole building structure will be deformed. If the damage is serious, it may even make the cold storage unusable. Therefore, in addition to the thermal insulation layer, the floor of low-temperature cold storage must be treated under the thermal insulation layer to prevent soil freezing. The bottom plate of the cold storage shall stack a large number of goods and pass through various loading, unloading and transportation machinery and equipment. Therefore, the structure of the cold storage plate shall be firm and have large bearing capacity. In low temperature environment, especially in the process of periodic freezing and thawing cycle, building structures are vulnerable to. Therefore, the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.The exhaust temperature of fresh-keeping storehouse is directly proportional to the compression ratio and suction temperature. If the suction superheat temperature of the fresh-keeping warehouse is high and the compression ratio is large, when the exhaust pressure increases, the exhaust temperature also increases.Install the library body. Generally, the warehouse body can be divided into small warehouse body and large warehouse body. The small warehouse body is basically a combined cold storage assembled with warehouse plate. The large warehouse body is mostly a civil cold storage. The assembled or constructed warehouse body is generally required to be flat, compact and solid, without hollow feeling, load-bearing, antifreeze, etc.Sania,It is required to set up a special tally room (area), and the temperature of the tally area is usually controlled at ~ + ℃.Generally, in the actual operation of the refrigeration system, because the temperature conditions are constantly changing, only by relying on the careful operation of the cold storage management personnel and accurately adjusting the operation of the refrigeration equipment of the cold storage,SaniaPreparation of vegetable fresh-keeping cold storage, can the refrigeration system always be in the ideal working state and achieve the effect of energy saving.The ground insulation of small, medium and large cold storage is different, which is closely related to the purpose storage products and size of cold storage. Kuhua refrigeration reminds: ground insulation must be done, which affects the quality of stored goods. So otherwise the temperature in the cold storage often fluctuates frequently due to poor insulation performance, what is the difference between the ground insulation of small, medium and large cold storage? How to do better?
