It can be interlocked with the refrigeration system, that is, it will not be humidified during refrigeration to prevent serious frosting of the fan.Precautions for purchase and shipment when using the medical cold storage project, the speed must be strictly guaranteed during the purchase and shipment of products. If the temperature of the medical cold storage is about degrees, the opening time must be strictly within minutes. If the temperature of the medical cold storage is left and right degrees, the opening time can not be too high, strictly within minutes.St. Thomas,What are the common sense of protection and maintenance of fresh-keeping warehouse equipment? Nowadays, the application scope of fresh-keeping storehouse is more and more extensive. It is closely related to our daily life. In addition to food production factories, stores and restaurants have begun to build fresh-keeping storehouses. The main purpose of building a fresh-keeping warehouse is to ensure the freshness of food. There are many precautions in the process of fresh-keeping warehouse. After completion, there are also many protection and maintenance items. Regular maintenance and protection of fresh-keeping warehouse can increase its service life. Therefore, it is necessary for operators to understand some common knowledge about the protection and maintenance of fresh-keeping warehouse equipment. What are the common knowledge about the protection and maintenance of fresh-keeping warehouse equipment?The overall construction achievements of the cold storage project have been put into use, and the service life can reach years.Oliveira,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, it shall be solved in time to avoid adverse effects.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.Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.
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.The wholesale evaporator of the fresh-keeping storehouse is used as a cold absorber for the wholesale of the fresh-keeping storehouse. The wholesale evaporator of the fresh-keeping storehouse is installed in the room of the cold-keeping storehouse, connected to the low-pressure end of the compressor, and has been installed for all kinds of cold-keeping storehouses with high prices nationwide for a long time. The cold-keeping storehouse is installed, constructed, fruit fresh-keeping cold-keeping cold-keeping cold-keeping, medical cold-keeping cold-keeping cold-keeping, The refrigerant dissipated by the compressor is used for evaporation and gasification, and instantly becomes low temperature and low pressure through the throttling device, so as to achieve the purpose of refrigeration.Installation of cold storage construction of cold storage, fruit preservation cold storage and medical cold storage have stable, safe,St. ThomasTemperature monitoring of medical cold storage, reliable and maintenance free performance. The technical level has reached the domestic level and the advanced level of similar international products. If there is a large amount of ice and water, it must be cleaned in time, and it must not be knocked during cleaning, so as not to damage the ground and affect the service life of the cold storage.Excellent quality,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?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, good permeability to water vapor, which is more dense than the surface of the air and the obturator rate is more than %. It is a dense microporous foam material, and is not easy to permeate. It is an hydrophobic material.
The construction of small cold storage is widely used in life, such as food industry, manufacturing industry, etc. since cold storage is so widely used, do you know cold storage? Especially the construction process and steps of cold storage. Understanding the construction process and steps of cold storage is helpful for all links of cold storage maintenance.assets,Where do you need to build the refrigerator, the size of the refrigerator or the storage capacity (size, storage capacity, ton, cubic meter, box); What products are stored in the built cold storage? The actual storage temperature, storage time and setting temperature can be indicated by specific regulations; If your cold storage becomes larger, you need to master your individual storage volume, the temperature of goods in and out of the warehouse, the frequency of opening and closing the door, etc. If this is clear,St. ThomasFreezer manufacturer, it is the selection of raw materials, such as refrigeration compressors, refrigeration units industrial cooling fans / pipe slots, thermal insulation materials, coolers, doors, temperatures and other refrigeration equipment.There are several types of insulation materials. One is to produce and process plates with fixed shape and specification, fixed length, total width and thickness. Plates of corresponding specifications and models can be selected according to the installation of the refrigerator body. High and medium temperature refrigerators generally use cm thick refrigerator plates, and ultra-low temperature refrigerators and freeze-cleaning refrigerators generally use cm or cm thick refrigerator plates; Another kind of sprayed polyurethane foam can be sprayed immediately into the finished brick or concrete warehouse. After forming, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane, polystyrene grease, etc. polyurethane is non hygroscopic and has good fire resistance, but the cost is high; Polystyrene resin has strong water absorption and poor fire resistance but the cost is low. The structure of modern cold storage is developing in the direction of dress matching architecture. They are made into prefabricated components including steam barriers and heat shields to ensure field assembly. Its advantage is that the project construction is convenient, fast and movable, but the project cost is relatively high.If there is more air or refrigerant oil in the evaporator, the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube, the heat transfer coefficient will be reduced. Similarly, if there is more air in the heat transfer tube, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced, and the decline rate of warehouse temperature will be slowed down.St. Thomas,The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, a simple analysis is made on the reasons for the slow drop of temperature: the cold capacity loss of quick freezing storehouse is large due to poor thermal insulation or sealing performance; the poor thermal insulation performance is due to insufficient thickness of thermal insulation layer of pipeline and warehouse thermal insulation wall, resulting in poor thermal insulation and thermal insulation effect,St. ThomasVegetable fresh-keeping storehouse, It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.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, 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 cold storage belongs to a kind of refrigeration equipment. Compared with the refrigerator, its refrigeration area is large, but they have the same refrigeration principle. So how to maintain the cold storage every day. Today I'll introduce how to do a good job in the daily management and maintenance after the installation of the cold storage.
