For cold storage， it is very common in our production and life. Cold storage is very important for food freezing and preservation， but its energy consumption is very large in the use of cold storage. How can we solve this problem?
How to maintain the refrigeration compressor in the cold storage in order to prolong its service life and reduce the occurrence of faults in the use process. The refrigeration compressor in the cold storage needs regular maintenance. Here we introduce the maintenance of the compressor in the cold storage.
OstanderThe ground should be flat and not uneven. If the ground is uneven， the ground of the warehouse must be leveled before the cold storage can be built and installed.
Wall and floor fixtures shall start at corners. According to the plate layout drawing， transport the two plates at the corner of the required device to the device location. According to the plate beam height and the model of the angle iron for fixing the mushroom head nylon bolt， drill a hole at the corresponding elevation in the middle of the plate width. When drilling， the electric drill should be perpendicular to the plate surface. Put the mushroom head nylon bolt in the hole， tighten the angle iron， and tighten it horizontally， foam data and other soft data should be laid on the floor slots along with the floor of the storehouse， so as to avoid damaging the storehouse. After the two corner panels are neutrally removed from the floor， the plane position of the wallboard and the verticality of the storehouse should be adjusted in time according to the location of the laying line， and check whether the top elevation of the wallboard can be correct. After the position of the wallboard is correct， weld the angle iron on the plate beam and fix the inner and outer corners. When welding the angle iron parts， the angle iron parts of the warehouse plate shall be covered with a shield to avoid the high temperature of the welding ground baking the warehouse plate and welding slag on the warehouse plate during electric arc welding.
San Iria Da yazoaCold storage has good fire and flame resistance. After adding flame retardant polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire， it can be carbonized， unlike flow burning and flashover like extruded board， which can effectively prevent fire spread. In particular， it can be closed as a whole after fire prevention treatment to form non combustible products.
For cold storage， it is very common in our production and life. Cold storage is very important for food freezing and preservation， but its energy consumption is very large in the use of cold storage. How can we solve this problem?
The product shade warehouse is a warehouse location below ℃ and the sun cannot be straight. The humidity is % ~ % relative humidity， and there are corresponding strict requirements for the wall， ceiling， ventilation， disinfection and epidemic prevention of the warehouse. The refrigeration system adopts full-automatic microcomputer electrical technology and does not need to be on duty. It mainly stores western and Chinese grass materials and instruments， and can monitor and record the temperature and humidity in the storage area.
In the cold storage project， the selection of cold storage is related to the overall operation of cold storage in the future. The selection of high-quality cold storage is conducive to the use and maintenance of cold storage. This requires us to inquire more about the warehouse board for cold storage engineering. Before the construction of cold storage project， we should first realize the temperature requirements of cold storage and the importance of cold storage to cold storage. Because the cold storage project has high environmental requirements such as temperature， attention should be paid to the performance and material of the cold storage board when selecting the cold storage board.
Frequently check and acknowledge whether the voltage of the power supply meets the requirements， the main power supply of the fresh-keeping warehouse shall be cut off， and it shall be ensured that the fresh-keeping warehouse equipment is not affected by moisture， dust and other substances. The condenser on the refrigeration unit is simply contaminated， and the fresh-keeping warehouse shall be cleaned regularly according to the actual situation. To adhere to outstanding heat transfer.
Panel types of quick freezing warehouse: color plastic steel plate， salted steel plate， stainless steel plate， embossed aluminum， etc.
Service firstSimple refrigeration is based on the volatilization of refrigerant in the condenser of the cold storage， so as to cool the refrigerant， and then input the refrigerant into the box or building of the refrigeration equipment to cool the air according to the heat exchanger. This kind of refrigeration has slow cooling speed， large total heat conduction temperature difference and complex system software， so it can only be used in less places， such as brine ice making and cold storage with constant temperature requirements.
Polyurethane refrigeration board uses light polyurethane as the internal material of refrigeration board. The advantage of polyurethane is very good heat insulation. The exterior of the cold storage is composed of SII， PVC color steel plate and stainless steel plate. The advantage of this is that it can prevent refrigeration， because the temperature difference inside and outside the board is large， and the temperature will disperse， which makes refrigeration more energy-saving and improves the working efficiency of refrigeration.
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， 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.
During the installation of long-span top warehouse plate， if the supporting steel beam has been installed in the warehouse， the top warehouse plate and the supporting steel beam shall be fixed with pull rivets during the installation of each warehouse plate， and each top warehouse plate shall be riveted in two rows; If the lifting point type is adopted， the installation and construction of the lifting layout shall be realized before the installation and construction of the top silo plate，OstanderQuotation for design and installation of cold storage， 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.
Evaporator， which is not only an exchanger for refrigeration and cooling but also a very important device. Its task is cooling. It is mainly used for refrigeration and heat absorption in cold storage. During long-term operation， the fins of the evaporator will also be covered with dirt， plus dust and other things，OstanderWhich one to choose for cold storage installation， but reaching a certain thickness will affect the cooling， resulting in poor refrigeration. Normally， it should be cleaned with special cleaning agent for the evaporator.
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.
OstanderWhen installing the polyurethane insulation board， the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.
Polyurethane refrigeration board uses light polyurethane as the internal material of refrigeration board. The advantage of polyurethane is very good heat insulation. The exterior of the cold storage is composed of SII， PVC color steel plate and stainless steel plate. The advantage of this is that it can prevent refrigeration， because the temperature difference inside and outside the board is large and the temperature will disperse， which makes refrigeration more energy-saving and improves the working efficiency of refrigeration.
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
