Las VegasInstallation of small cold storageAre you familiar with the code of conduct
2022-03-07 00:13:49Insufficient refrigeration dose and capacity in the system: there are two main reasons for insufficient refrigerant circulation,Whether there is a problem with the line system of the first controlled atmosphere storage. After the line problem is eliminated, check whether the cold storage is overloaded. If there is a problem with the line, please deal with it in time. When the power is overloaded, the power or increase the square of the line.The spacing of pull rivets at inner and outer corners is mm and mm respectively; After the polystyrene library is installed, the wall panel joints shall be evenly sealed and decorated with silicone sealant.details,First, use a hammer to pad the wood on the polyurethane warehouse board between the two warehouse boards, so as to make the boards closely close to each other. Two sets of connecting pieces shall be wedged between the wall panel and the wall panel and the two sets of connecting pieces shall be fixed on the upper, outer and lower sides of the gap between the wall panel and the wall panel respectively. The lower connecting piece shall be as close as possible to the lower side,Las VegasHow much is a small cold storage, so that the post cast concrete can cover the connecting piece. After the gap between the plate and the plate ground is wedged with a connector, it shall be about mm wide. If it does not meet the requirements, remove the plate, trim the plate edge, and then reinstall it to make the plate joint meet the requirements. When fixing the adapter, pay attention to fix the two parts of the adapter on the edges of the convex and concave library plates respectively, the hammer shall be perpendicular to the wedge iron to prevent damaging the warehouse plate. The ground wedge iron at the upper and lower parts shall be wedged at the same time, which can be determined according to their own budget and actual needs. At present, and are equipped with combined thermal insulation storage body, unloading platform, refrigeration system, system, pipeline system, etc. according to the actual needs of cold storage circulation.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.
The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, resulting in poor thermal insulation and thermal insulation effect 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, It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.Customer first,Requirements for refrigeration equipment in quick freezing warehouse: the strict sealing of quick freezing warehouse is obviously different from that of ordinary quick freezing warehouse. Therefore, how to seal the refrigeration equipment is the key. First of all, all through wall pipelines must be equipped with sleeves, the frost flushing water return pipeline must be equipped with U-shaped bend water seal, and the main frost flushing and return pipeline outside the warehouse shall be equipped with air filling port to prevent the gas in the warehouse from being pumped out of the warehouse by negative pressure. In addition, due to the good sealing of the quick freezing warehouse, the set fluctuation range of the warehouse temperature should not be too large to prevent excessive positive and negative pressure from damaging the warehouse body.Maintenance space shall be reserved for the installation of the unit to facilitate the observation of the adjustment of instruments and valves.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.Las Vegas,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,Las VegasQuotation for freezer design, 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.When outdoor air enters the cold storage body, it will not only increase the cold consumption of the cold storage, but also bring water into the warehouse. The condensation of water will lead to the building structure, being damaged by moisture and freezing. Therefore, a moisture-proof and heat insulation layer should be set to keep the cold storage board building moisture-proof and air-proof performance and good sealing.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, the vast majority of cold storage use polyurethane insulation board. What are the characteristics and advantages of polyurethane insulation board?
