Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment, use the volatilization of the refrigerant to immediately cool the air in the air, and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed, small heat conduction temperature difference and simple system software, so it is widely used.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, and is not easy to permeate. It belongs to hydrophobic materials.Bouquet cross,Bouquet crossFresh and cold storage installation service,The exhaust temperature of the compressor in the fresh-keeping warehouse can be read out from the thermometer on the exhaust pipeline. It is related to the adiabatic index, compression ratio and suction temperature of refrigerant. The higher the suction temperature, the greater the compression ratio, the higher the exhaust temperature, and vice versa.Install the electric control system. The electric control system of the cold storage mainly includes electric controller, lighting and other electrical equipment in the cold storage. The power supply of the cold storage is required to be stable phase line, and the power supply or backup power supply can be used as required. The circuit shall have reasonable discharge and corresponding protective measures.Yakutsk, - Installation of the vertical plate of the cold storage: select the angle first according to the site conditions and locate it (i.e. lock the vertical plate and the floor) to extend to both sides at this angle. Only lock the vertical plate and the vertical plate, and locate it when it meets the vertical angle. Put the beautiful plate in a conspicuous place. When installing it on the side of the evaporator, make the drainage pipe in advance, and make U-bend and silica gel outside the storage.In the cold storage project, the selection of cold storage is related to the overall operation of cold storage in the future. The selection of high-quality cold storage is conducive to the use and maintenance of cold storage. This requires us to inquire more about the warehouse board for cold storage engineering. Before the construction of cold storage project, we should first realize the temperature requirements of cold storage and the importance of cold storage to cold storage. Because the cold storage project has high environmental requirements such as temperature, attention should be paid to the performance and material of the cold storage board when selecting the cold storage board.Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, and the dry consumption of cold food is also large; For the low-temperature warehouse, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level, it is impossible to deal with it, which is easy to cause horizontal freezing and swelling.
The height of the warehouse, the horizontal and vertical of the warehouse shall be designed according to the refrigeration refrigeration equipment, the vast majority of cold storage use polyurethane insulation board. What are the characteristics and advantages of polyurethane insulation board?When installing and splicing the storeboard in the fresh-keeping storehouse transportation and stacking conditions. The selection of insulation board is very important for Guangdong cold storage. At present, it needs to be tightly sewn to ensure the tightness; The fresh-keeping storehouse will discharge water during operation, and the drainage pipe should be installed in a place that can circulate; An anti-collision barrier shall be installed around the door of the fresh-keeping storehouse to prevent the door from being damaged by impact. To play an eye-catching role, the fresh-keeping storehouse shall be equipped with emergency lights, alarm devices and safety channels to facilitate self rescue or alarm for help in case of emergencies.Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large, and I found that it is cheap to replicate cold through actual field investigation.safety requirements The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, but use fan to supply air for refrigeration, because the gas in the quick freezing storehouse needs to be circulated and dispersed regularly to avoid carbon oxide poisoning caused by high concentration of carbon oxide in local areas. Therefore, the refrigeration equipment needs to be used together with the air conditioning equipment. The selection of refrigeration equipment is different from that of low-temperature freezer and ordinary quick freezing warehouse.A large number of personnel are not allowed to select goods in the warehouse. Close the warehouse door in time. When the warehouse door is opened, pay attention to whether the air curtain is opened or the door curtain is placed properly. Turn off the lights when leaving the warehouse.Installation of unit electrical box: the unit electrical box shall be installed near the unit; Vertical installation. If the unit is installed on the top of the warehouse,Bouquet crossInstallation and construction price of cold storage, the distance between the box bottom and the top of the warehouse must be & amp; gt; mm; The electrical box can be fixed on the building wall or on the angle steel frame.
No matter whether the food cold storage or quick-frozen storage is in use, it is inevitable that there will be various small faults. Don't be nervous when there are problems. You can find or eliminate problems according to the knowledge taught today.system,Technical assurance measures for the installation of cold storage: during production in the production workshop, the production shall be carried out in strict accordance with the operation rules specified in ISO quality operation, self inspection and inspection application shall be carried out to ensure that the factory pass rate is, and unqualified products are not allowed to leave the factory.Because long-term wind and sun exposure is easy to cause line aging, short circuit, leakage and other accidents; After the fresh-keeping storehouse is installed and connected,Bouquet crossDesign of small cold storage, it is necessary to start and debug the fresh-keeping storehouse, and adjust the value of the fresh-keeping storehouse to the appropriate temperature; The installation unit of fresh-keeping storehouse needs to provide the user of fresh-keeping storehouse with knowledge training on how to use and manage the fresh-keeping storehouse, as well as some after-sales training.Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area, height and warehouse temperature of the cold storage on the basis of safety, science and rationality, from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.Bouquet cross,During installation, the plates shall be handled with care. Rough operation is strictly prohibited. Burrs shall be removed at the cutting opening to prevent scratching the plate surface and workers.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, can the refrigeration system always be in the ideal working state and achieve the effect of energy saving.Operating the unit: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops
