EskipulasInstallation and maintenance of cold storageAnalysis of common pipe cutting methods

The selection of cold storage is very important for cold storage, because cold storage is different from ordinary cold storage. The temperature in cold storage is usually low, and the air temperature, humidity and environmental requirements are relatively high. When selecting cold storage, attention must be paid to the selection of cold storage with better temperature. If the selection of cold storage is not good, the temperature in the cold storage is difficult to, which is easy to cause the deterioration of products in the cold storage, wasting more resources and increasing the cost.If there is more air or refrigerant oil in the evaporator, the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube, the heat transfer coefficient will be reduced. Similarly, if there is more air in the heat transfer tube, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced, and the decline rate of warehouse temperature will be slowed down.Eskipulas,EskipulasWhich one do you want for cold storage installation,If the controlled atmosphere storage works continuously for more than h, medium maintenance shall be carried out. The condenser, evaporator and cooling drain pipe are cleaned and adjusted, the cooling water distribution device is cleaned and adjusted, the brine distribution device is cleaned and adjusted, the cooling drain pipe is repaired and the pipe leakage fault is eliminated.When hot ammonia defrosting or electric defrosting is selected as the cooling fan, professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, safety, environmental protection and economy! The products are exported to foreign countries and are deeply trusted. Defrosting and drainage can be discharged immediately. Electric heat tracing and insulation can be selected for the defrosting and drainage pipeline of the warehouse location.ApamThe three-dimensional automatic cold storage adopts a computer, which can complete the loading, unloading and stacking in the storage, the quick-frozen warehouse increases the regulation of gas composition, inhibits the respiration of fruits and vegetables, delays their metabolic process, better maintains the freshness and commercial quality of fruits and vegetables, and prolongs the storage period and shelf life of fruits and vegetables. Generally, controlled atmosphere storage of fruits can prolong the storage period by & mdash; Three times or more. OK, what is the standard of quick freezing warehouse?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.

Various construction materials, such as material certificate, test report and stage acceptance record, shall be carried out simultaneously with the project construction, carefully, timely, accurately and comprehensively reflect the whole process of production and construction, and actively cooperate with the owner in design change and technical negotiation.Material requisition for the installation requirements of the assembly fresh-keeping warehouse: according to the engineering design and construction material list the materials shall be sent to the accessories warehouse, and the materials and accessories models shall be carefully checked.The butt joint between the top warehouse plate and the end of the top warehouse plate shall be treated to prevent air leakage and cold running. After all the top warehouse plates are installed, the butt joint shall be filled with foaming material, and the mm wide color steel plate shall be sealed at the butt joint with pull riveting.Quality recommendation,The ultrasonic town is a patented technology with a shaped energy cover, which increases the effective humidification amount by -% per hour. What are the reasonable aspects of the design of the quick freezing warehouse?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.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.

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, 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,EskipulasWhere is a good place to install cold storage, 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.technological innovation,Disadvantages of multi-layer cold storage: the vertical transportation volume of the warehouse is large, and the goods in and out and operation management are not as convenient as single-layer cold storage; With the development of the floor load capacity, the floor area ratio of each cold room is low; When the multi-storey cold storage is built on the foundation with poor ground resistance, the foundation construction is complex. High cost; When prefabricated components are used, large construction equipment is required and the construction period is long.Regularly maintain whether the connecting pipes on the connecting pipes and valves of the refrigeration unit are firm and whether there is refrigerant leakage. The way of leak detection is to use sponge or thin cloth with detergent, foam, and then evenly coated in the area to be leaked and observe for a few minutes. If water leaks, use the volatilization of the refrigerant to immediately cool the air in the air and then tighten or gas cut it.Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment, 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.Eskipulas,Drainage measures shall be provided for the villa room and overhead layer of the road surface of the cold storage engineering building.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, it is impossible to condense in the wall due to the obstruction of the cold storage.The two sets of connectors between the cold storage shall be wedged tightly,EskipulasFruit freezer installation, and the two sets of connectors shall be fixed at the upper, outer and lower sides of the cracks in the cold storage respectively. The lower connector shall be as close as possible, so as to facilitate the use of concrete to cover the connector in the future.
