Danfoss thermal valve is adopted for the thermal valve of the cold storage, with guaranteed quality; Due to the high temperature requirements of the cold storage and the high degree of automation and regulation of the temperature,BayagunaWhat is a cold storage, the temperature system of the cold storage adopts microcomputer full-automatic, does not need special people to operate, and can be remotely controlled. When the temperature exceeds the specified range, which is of great significance to the proper preservation of the cold storage.Polystyrene foam: polystyrene foam is a new type of synthetic thermal insulation material. It is a kind of plastic, with small density, light weight, strong heat insulation effect and excellent low temperature resistance. However, due to its cold shrinkage, it is not very convenient for installation.Bayaguna,Vacuum test: after the system pressure test is qualified, the system can be vacuum leak tested. The purpose is to improve the air tightness under vacuum conditions and prepare conditions for ammonia filling of the system.The polyurethane insulation board used in the construction of cold storage shall be integral and continuous, and there shall be no joint in the middle. The junction of polyurethane insulation board top plate and ground shall be made into fillet arc for transition, which can well meet the health needs.Sekudai,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 can not be too high, strictly within minutes.The height of the warehouse the horizontal and vertical of the warehouse shall be designed according to the refrigeration, refrigeration equipment, transportation and stacking conditions. The selection of insulation board is very important for Guangdong cold storage. At present, and timely deal with the problems of insulation and seal failure such as degumming and air leakage.
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.After the fresh-keeping storehouse is built, it is also important to pay special attention to the maintenance of fresh-keeping storehouse equipment in the whole process of application. Here are some key maintenance matters.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, moisture-proof, etc.Process inspection,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 is mainly used for frozen processing and storage of foodCommissioning cold storage. After all parts of the cold storage are installed and connected, the cold storage can be started for cold storage commissioning. According to the needs of customers, adjust the value of the cold storage, the cold storage can reach the predetermined temperature, the cooling speed and the operation of the cold storage are normal, and the cold storage can be delivered for use. The cold storage installation unit shall also provide the cold storage user with training on cold storage use and management knowledge, as well as some after-sales training.
These are several very common cold storage materials. The use of these materials has greatly improved the thermal insulation and refrigeration performance of the cold storage, which makes people's retained items more convenient and reliable. With the continuous development of material technology, today's various cold storage materials emerge in endlessly,BayagunaInstallation of cold storage and quick freezing storage, and the cold storage is different from each other. When purchasing, we should make reasonable comparison and select products suitable for our own use needs and economic conditions.safety requirements ,Step of cold storage design: define the volume of the cold storage warehouse. The size of the cold storage should be based on the design of a large number of agricultural products to be stored for a long time. This volume is calculated based on the essential volume of stored goods accumulated in the cold storage, plus the row to row corridors, the indoor space between the pile and the wall, the ceiling and the gap of the packaging house. After the volume of the cold storage is determined, the length and height width ratio of the cold storage shall be determined. Necessary auxiliary engineering buildings and equipment shall also be considered in the design of cold storage, such as working intermediate, packaging and combing room, special tool warehouse, loading and unloading platform, etc.The function of refrigeration is & amp; amp; ldquo； Low temperature storage & amp; amp; rdquo； Introduction & amp; amp; ldquo； Loop type & amp; amp; ldquo； Cold chain logistics & amp; amp; rdquo；Watertight polyurethane rigid foam has low water absorption, good permeability to water vapor, and state of foam pores. It is not connected with each other, and the obturator rate is more than %. It is a dense microporous foam material, which is more dense than the surface of the air, and is not easy to permeate. It is an hydrophobic material.Bayaguna,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, it should be determined according to the type 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, quantity, frequency,BayagunaProfessional cold storage manufacturer, 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 .-..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.We must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator, as a in the home still has some use environment. In the market or marine transportation, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage quality assurance. During the preferential activities, new and old customers are welcome to consult. The environmental differences inside and outside the cold storage insulation board are very large, because a large number of items need to be insulated, so the temperature in the cold storage is strict. In such cases, the cold storage insulation board will have relevant problems, Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse, and the penetration of the envelope is carried out from outside to inside all year round. R gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time, and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer, it is effective to seal the hot side of the insulation layer, that is, to form a vapor barrier layer.
