Able to withstand the harsh local climate and its changes. Neither high temperature nor severe cold climate will cause irreversible damage or deformation to the external insulation system. The drastic change of the surface temperature of the external wall, such as the sudden shower after a long time of exposure, will not cause damage to the surface of the cold storage.
agent.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, 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, and the penetration of the envelope is carried out from outside to inside all year round. R11 gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time, moisture becomes more and more serious, 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.
Cold storage design steps: selection and preparation of cold storage location. According to the application characteristics, cold storage can be divided into sexual cold storage, retail cold storage and large-scale cold storage. When large-scale cold storage starts to build a planting area with more centralized hand supply, factors such as superior geographical location and contact with the market should also be taken into account. The cold storage should be located in a cool place without sunlight and frequent warm air. Small and medium-sized cold storage is better
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, 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, it will automatically alarm, which is of great significance to the proper preservation of the cold storage.
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.
Design brand.The medical cold storage has been widely used in the industry. For the use of the medical cold storage project, we must combine the performance of the product and store it according to the temperature and humidity required by the product. The automatic temperature box also needs to be used outside the product cold storage. At the same time, the management personnel must be familiar with the operation steps of the medical cold storage project.
Ammonia filling leak test: ammonia filling leak detection can be carried out after system blowdown and pressure leak test. The purpose is to improve the air tightness of the system and lay a good foundation for the work of ammonia filling and thermal insulation materials of the system. After air leakage detection, some obvious leakage points can be found. However, due to the poor air permeability, the leakage points blocked by dirt along the tiny sand holes are not easy to be detected. Therefore, ammonia must be filled. In addition to good permeability, ammonia also has odor and is easy to be found, At the same time, phenolphthalein test paper can be used for leak detection because it is rose red in the presence of ammonia.
