The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.Different food processing technical processes for the construction of cold storage are combined with local urban planning. The construction of cold storage is the design requirements and construction of cold storage, which not only avoids the cross pollution between foods, but also ensures its transportation facilities: within the construction scope, a reasonable overall layout, saves land and reduces costs.Old harbour,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.Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.Radololita,When the cold storage is used for the first time or shut down for a long time, it is strictly prohibited to stack goods in the warehouse. The warehouse must be slowly reduced to the required temperature. For the low-temperature warehouse, it needs to be cooled in stages to avoid sudden changes in the temperature difference inside and outside the warehouse, resulting in the warehouse body.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.Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Cold storage fault phenomenon: dryer does not operate, thermal relay acts fuse is blown, high voltage switch acts,Old harbourCold storage machine plate installation, compressor is locked line is falsely connected or loose fault phenomenon: it stops in a short time after drying, ambient temperature is too high, condenser is blocked

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.Opening and closing of valves of refrigeration system.Regular oil discharge, descaling and air discharge: when there is a .mm thick oil film in the evaporator coil,Old harbourWhich one is better to install cold storage, the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm, the condensation temperature will rise by ℃ compared with the original temperature, and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa, the power consumption will increase by about . It can be seen that it is coldWelcome calls ,Cold storage design segmentation: several different partitions shall be reasonably planned and divided according to purpose and temperature. For example: processing room, sorting room, quick freezing room, refrigeration room, channel, unloading platform, etc. - precautions for vertical plate of cold storage: vertical plate displayThe products stored in the medical cold storage project must be managed by color code so as to avoid the problem of purchase errors. In the process of handling, it is also necessary to strictly follow the instructions.

After being stored in the medical cold storage project, ventilating medical products may also emit some odors. Once these odors are stored in a certain quantity, they will also have a certain impact on other products. Therefore, we must carry out regular ventilation in the process of daily use, so as to effectively reduce the storage time of products. If the medical cold storage project uses row tube refrigeration, the image of frosting may appear after use for a period of time. If we do not defrost in time, it will also affect the effect of. Therefore,Kg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, the polyurethane board has very good thermal insulation performance and does not absorb moisture.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；Establish a perfect computer network, make the distribution of refrigeration supply chain scientific, and achieve the traceability of food safety. In the European Union, the United States and Japan, all members of the food supply chain have the legal responsibility to implement traceability.Old harbour,Now let's analyze the production and use requirements of the cold storage. There is no condensation in the cold storage. Condensation in the cold storage or in the insulation layer is harmful. During the drying process of the new wall or under winter conditions, when the water vapor with high indoor temperature migrates outdoors, you must remove all the influences. It is very important to recognize that when these beautiful refrigerators are built in the villa room, the collection pit (pool) for flushing (thawing) and drainage should adopt the Countermeasures of avoiding freezing and cleaning and avoiding backflow of water.Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is ~ kg / m, the thermal conductivity is only . ~ .w / (m.k), which is the lowest among all thermal insulation materials at present.
