On the basis of cold storage and preservation, 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?Cold storage is mainly used for frozen processing and storage of foodPort amuellis,For the selection of air conditioning units, it is necessary to consider the condensation pressure and other related problems of the unit, increase the proportion of outdoor cold air, and achieve the effect of energy saving.When installing the polyurethane insulation board,Port amuellisInstallation cold storage manufacturer, the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.Esparza,However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.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.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.
The refrigeration equipment in the fresh-keeping environment of the quick-frozen warehouse mostly adopts the single-stage compression refrigeration system, with freon as the refrigerant. The evaporation mode in the warehouse is the cooling fan which can be ceiling type. If the number of warehouses is small and the volume does not exceed cubic meters, the refrigeration mode of the warehouse machine can be considered. If there are a large number of warehouses, the mode of multiple heads in parallel can be considered.Another point is the ground maintenance measures in the wholesale of large fresh-keeping warehouses., Because the wholesale floor of large-scale prefabricated fresh-keeping warehouse is also a thermal insulation board, there will be a lot of ice on the ground in the process of use, you should pay attention not to beat them with a hammer or shovel, because it will damage the thermal insulation board on the ground. If the thermal insulation board is damaged, it will affect the thermal insulation performance of the wholesale of fresh-keeping warehouse.Preparation, prepare the project planning of cold storage, and prepare the construction site and construction materials. All kinds of materials for cold storage construction are customized according to the needs of customers. Sort out the construction site that meets the requirements, transport all installation materials to the construction site, check the material quality and model, and start the installation of cold storage after confirmation.offer,Install the library body. Generally,Port amuellisDesign of cold storage, the warehouse body can be divided into small warehouse body and large warehouse body. The small warehouse body is basically a combined cold storage assembled with warehouse plate. The large warehouse body is mostly a civil cold storage. The assembled or constructed warehouse body is generally required to be flat, compact and solid, without hollow feeling, load-bearing, antifreeze, moisture-proof, etc.There are many application scenarios of cold storage, which are different. For a long time, it provides various cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, on-site settlement, and has offices all over the country for long-term cooperation. Different purposes, functions and designs so what needs to be understood in cold storage design?More and more people begin to build cold storage, and most people choose to use cold storage for cold storage construction. Why? Why do people choose cold storage for construction? What are the advantages of cold storage? The following is a detailed introduction.
During production in the production workshop, the unit weight of Pu warehouse board shall not be less than the unit weight required by the project, not less than & plusmn; kg/m.Product survey,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.The selection of the refrigeration system of the controlled atmosphere storage is mainly the selection of compressor and evaporator. The refrigeration system is the core of the controlled atmosphere storage, which is mainly composed of compression system, condensation system, there are auxiliary parts such as fan, duct and instrument. The whole refrigeration system is a sealed circulating circuit in which the refrigerant circulates, The compressor is the heart of the refrigeration system which promotes the circulation of refrigerant in the system. The function of the condenser is to remove the heat from the compressed gaseous refrigerant and condense it into liquid refrigerant; The cooling methods of the condenser include air cooling, water cooling and the combination of air and water. Air cooling is only used in the refrigeration equipment of small-scale air-conditioned storage. The role of the evaporator is to provide cooling capacity to the air-conditioned storage. The evaporator is installed in the air-conditioned storage. The blower blows the cooled air to all parts of the storage. The air duct of large-scale air-conditioned storage is commonly connected with the evaporator to extend the air supply distance, Make the storage temperature drop and even.The construction of small cold storage is widely used in life, such as food industry, manufacturing industry, etc. since cold storage is so widely used, do you know cold storage? Especially the construction process and steps of cold storage. Understanding the construction process and steps of cold storage is helpful for all links of cold storage maintenance.Port amuellis, the board surface shall be wiped clean. If there is any scratch, it shall be treated. There shall be no obvious scratch on the board surface.Installation of cold storage, construction of cold storage fruit preservation cold storage and medical cold storage have stable, safe reliable and maintenance free performance. The technical level has reached the domestic level and the advanced level of similar international products. If there is a large amount of ice and water, it must be cleaned in time, and it must not be knocked during cleaning, so as not to damage the ground and affect the service life of the cold storage.The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor, the cylinder sleeve, ring and other parts are seriously worn, the long-term cold storage installation, installation,Port amuellisFreezer installation engineering company, construction, fruit preservation, medical cold storage and other brand products, the designated products are complete, and the sealing performance will be reduced accordingly with the increase of the matching clearance, The gas transmission coefficient of the compressor will also be reduced, and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.
