More and more people begin to build cold storage, and most people choose to use cold storage for cold storage construction. Why? Why do people choose cold storage for construction? What are the advantages of cold storage? The following is a detailed introduction.Whether the water pump works normally and whether the moldy switch is effective. In case of abnormality, timely handle the overhaul and maintenance of the refrigeration compressor in the cold storage: generally, the refrigeration oil and drying filter shall be replaced times after the operation of the cold storage equipment. Replacement after half a year. Depending on the circumstances.Sabaneta,The knowledge of cold storage repair and maintenance is something you can't fail to understand in the process of daily use of cold water! - floor installation of cold storage: first level the floor, then install the floor, and do a good job in the floor and evaporator drainage system.Santa Coloma de Gramenet,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, uniform temperature in the warehouse, and can bring harmful gases such as carbon oxide out of the warehouse during storage.Because polyurethane sheet has excellent thermal insulation performance, it can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.
Cold storage plate features: good thermal insulation performance, light weight, high strength, corrosion resistance, anti-aging, each contact shall be installed with wire number for maintenance.For 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.Scheme customization,The combined cold storage does not cool or the cooling effect is poor. Check whether the condenser of the refrigerator is dirty. Whether frost is too thick on the evaporator in the warehouse. Check whether the refrigerant is leaking (apply soapy water to the pipeline connection, and if bubbles are generated, it indicates that the refrigerant is leaking). And ask the combined cold storage engineering personnel to supplement the refrigerant and deal with the leakage. Check whether the sealing of the combined cold storage door is intact and eliminate it. Whether the refrigerator of the combined cold storage works. Whether the parameter setting of the computer controller of the cold storage is correct, and reassemble the cold storage door for installation. Check whether the cooler in the cold storage fails and replace it. Whether there is enough clearance for stacking articles in the warehouse and dredge them.The bacterial action of acid disinfectants is mainly to coagulate the protein in the bacteria. Common disinfectants include lactic acid, bleach, formalin, etc. Specifically, after the fish comes out of the freezer, clean the frost layer on the evaporating pipe group and keep the storehouse temperature below degrees Celsius. Then, according to the volume of ~ grams per cubic meter volume of the frozen storeroom, the storeroom door is closed tightly with the sprayer and the blower is started intermittently, so that the vinegar evaporates and flows in the storehouse, which makes the vinegar absorb a lot of fish smell.Initial stage of cold storage equipment
Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor,SabanetaCold storage installation Cold Storage, fan and other equipment. In case of abnormal sound, so as to avoid greater damage to the compressor due to untimely warranty.Fair price,When the cold storage is used for the first time or shut down for a long time, it is strictly prohibited to stack goods in the warehouse. The warehouse must be slowly reduced to the required temperature. For the low-temperature warehouse it needs to be cooled in stages to avoid sudden changes in the temperature difference inside and outside the warehouse, resulting in the warehouse body.The volume of the controlled atmosphere warehouse the size of the controlled atmosphere warehouse shall be calculated according to the volume occupied by the storage products stacked in the controlled atmosphere warehouse, plus the aisle between rows, the space between the stack and the wall and ceiling, and the gap between the packaging. After determining the capacity, the length and temperature of the controlled atmosphere warehouse shall be determined. The design of the controlled atmosphere warehouse shall also consider the necessary auxiliary buildings and facilities, such as workshop Packing and sorting room, tool warehouse and loading and unloading platform, so that the quality of controlled atmosphere warehouse can be guaranteed.Kg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, the polyurethane board has very good thermal insulation performance and does not absorb moisture.Sabaneta,SabanetaHow much is the installation of cold storage per square meter,SabanetaPrice of cold storage,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.The new cold storage material is made of rigid polyurethane or polystyrene foam insulation sandwich panel, which is made by high pressure foaming process and can be made into various lengths and specifications to meet the different requirements of the users.The foaming technology of polyurethane with strong stability makes it have superior bonding performance. The firm combination of polyurethane rigid foam and carrier layer is the basic premise to ensure the stability of external insulation layer. That is, it can bear various internal and external combined loads such as wind force, self weight and normal collision and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.
