Reasonable space: the power consumption of the cold storage is calculated according to the cold consumption of the cold storage, which usually includes two parts: the cold consumption during cargo cooling and refrigeration; It is the cooling consumption of the refrigeration room itself and operation management.Artificial refrigeration keeps the room at a constant temperature. The walls, floors and flat roofs of large cold storages are laid with thermal insulation materials with a certain thickness to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation the surface of the external wall of the cold storage is painted white or light color.colon,After evacuation, fill the refrigerant into the liquid storage to % of the standard filling volume & mdash; % by weight, then run the compressor and add gas from low pressure to sufficient volume.With the development of the times, refrigeration devices are becoming more and more common. All aspects of life are inseparable from its use. Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage it is important to select materials with good thermal insulation. Cold storage is a better material selection, and manufacturers need to grasp its key points in the production process of cold storage.Bailesti,Connect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit, electric control system and other components of the cold storage. The connecting pipes shall be closely connected, and corresponding thermal insulation and protection measures shall be taken.The refrigerant charge is insufficient. At this time, just add enough refrigerant.The construction structure of structural cold storage can be brick concrete structure or steel structure which can be determined according to their own budget and actual needs. At present, most cold storages are constructed with single-layer steel structure, and are equipped with combined thermal insulation storage body, unloading platform, refrigeration system, system, pipeline system, it is very important to select materials with good thermal insulation. Cold storage is a better material selection, and in the production process of cold storage, there will be no condensation in the cold storage of the plant. Condensation inside the cold storage or inside the insulation layer is harmful. Irreversible damage or deformation occurs in the new external insulation, and the external surface temperature of the external wall changes sharply. For example, the insulation and sound insulation effects of polyurethane insulation board are relatively good, which can be used in many industries. As we all know, the cold storage has great requirements for the thermal insulation effect of building materials. If the thermal insulation effect of building materials is not good, the cold storage will consume more energy during operation, and can not guarantee a good refrigeration effect. The performance of polyurethane insulation board meets the construction requirements of cold storage, so a large number of polyurethane insulation boards need to be used in the construction of general cold storage. Next, let's understand the physical properties of polyurethane insulation board.Ice cubes are always available in the cold storage. For small cold storage, the cost of using standby power supply or generator set is too high and the cost performance is low. In this case, some ice cubes must be always available in the cold storage. In case of power failure or refrigeration equipment failure, ice cubes can be used to maintain the temperature in the cold storage.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.Superior quality, floors and flat roofs of large cold storages are laid with thermal insulation materials with a certain thickness to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, the surface of the external wall of the cold storage is painted white or light color.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.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.

The spacing of pull rivets at inner and outer corners is mm and mm respectively; After the polystyrene library is installed,colonInstallation cost of fresh-keeping cold storage, the wall panel joints shall be evenly sealed and decorated with silicone sealant.Online consultation,The two sets of connectors between the cold storage shall be wedged tightly, and the two sets of connectors shall be fixed at the upper, so as to facilitate the use of concrete to cover the connector in the future.We also need to maintain the wholesale storeboards of fresh-keeping storehouses regularly. For example, in the daily use of fresh-keeping warehouse wholesale, we should avoid scratching or collision caused by objects on the warehouse board. The purpose of this is to avoid dents and scratches after the wholesale warehouse board of fresh-keeping warehouse is impacted. In serious cases, it may also affect the refrigeration effect of fresh-keeping warehouse wholesale, resulting in the reduction of local temperature control effect of cold storage.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,colonWhere is the installation of cold storage, Polyurethane insulation board has also become one of the main exterior wall materials.colon,In order to maintain a constant low temperature in the cold storage, attention should be paid to the installation of cold storage panels in Guizhou: the floor, wall and flat roof of the cold storage are laid with a certain thickness of thermal insulation materials to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, the surface of the external wall of the cold storage is painted white or light color. Therefore,colonHow to charge for the installation of cold storage, cold storage building is different from general industrial and civil buildings, and has its unique structure. Cold storage buildings should prevent the entry of air and the diffusion of water vapor.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, under the unfavorable local temperature and humidity conditions 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.Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking, every ℃ increase in the evaporation temperature of the cold storage can save energy by ~ . Therefore, on the premise of meeting the refrigeration process of the product, the liquid supply can be adjusted to increase the evaporation temperature as much as possible.
