its installation quality will directly affect the temperature of cold storage. As an important structure used in the cold storage, the cold storage board should pay attention to the details of its installation, find out the problems that are easy to be ignored, and avoid the wrong installation, which will affect the use of the cold storage or the whole installation process, so as to waste resources and increase the cost.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.Kurnawaka,Vacuum test: after the pressure test of the fresh-keeping storehouse system is qualified, the vacuum leakage test of the fresh-keeping storehouse system can be carried out. The purpose is to improve the air tightness under the vacuum condition of the fresh-keeping warehouse and prepare the conditions for the ammonia filling of the fresh-keeping warehouse system.The ground insulation of small, medium and large cold storage is different, which is closely related to the purpose, storage products and size of cold storage. Kuhua refrigeration reminds: ground insulation must be done otherwise the temperature in the cold storage often fluctuates frequently due to poor insulation performance, which affects the quality of stored goods. So, what is the difference between the ground insulation of small, medium and large cold storage? How to do better?Sagarejo,Points of multi-storey cold storage: small, which can save land; When the storage capacity is the same, so that the cold consumption can be reduced, the dry consumption of food can be reduced, and the machinery and equipment cost and operation and management cost can be reduced accordingly. At the same time, due to the saving of thermal insulation materials the civil construction cost per unit area is low and the investment cost is small; The multi-storey location can be reasonable, such as the cooling room can be used as the cold storage room, the attic on the top floor can be built into the ice making room, etc. - precautions for vertical plate of cold storage: vertical plate displayThe physical properties of polyurethane insulation board are relatively good, which can meet different needs. The polyurethane insulation board is also strict in the selection of materials. It is a special product manufacturing enterprise integrating R & D, and service. It has long been specialized in cold storage installation, cold storage installation,KurnawakaHow much does it cost to install the cold storage, cold storage construction, fruit preservation cold storage and medical cold storage. It improves the overall performance of the polyurethane insulation board and enables the polyurethane insulation board to work for a long time, Polyurethane insulation board has also become one of the main exterior wall materials.

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.For the installation of refrigeration unit oil separator shall be installed for semi sealed or fully sealed compressor, and an appropriate amount of oil shall be added in the oil. When the evaporation temperature is lower than - ℃,KurnawakaCold storage compressor installation, gas-liquid separator and an appropriate amount of refrigeration oil shall be added.Install the temporary lighting facilities in the warehouse, install and arrange the construction electrical equipment and do a good job in rain proof, moisture-proof, anti-collision, anti binding and other safety protection.ranking,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.It is strictly prohibited to place articles with pollution and peculiar smell around the cold storage. The surrounding environment of the cold storage must be cleaned and disinfected regularly every day,KurnawakaProfessional installation of cold storage, and the door of the cold storage must be locked.The 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.

The equipment that needs to be installed in the warehouse and put into the warehouse shall be installed in place or placed in an appropriate position in the warehouse; The wall warehouse board shall be installed from the corner of the warehouse body, good waterproof performance, fire and high temperature resistance, strong overload capacity, corrosion resistance, radiation protection and long service life. The corner shall be temporarily fixed with . color plate angle steel; When installing each wall panel, evenly apply two layers of foaming material on the joint surface of male and female groove, and apply one layer of foaming material when installing polystyrene wall panel. The blanking shall be uniform and continuous; After the wallboard is installed in place, pull rivets at the lap joint of the internal and external steel plates of the two wallboards for connection and fixation, and the rivet spacing in the warehouse should be mm; When connecting the library plate in the form of eccentric hook connection, the eccentric hook shall be loosened once before installation to ensure reliable locking during installation.Honest service,For the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of ~ mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.The distribution box is installed horizontally and vertically, the ambient lighting is good, and the room is dry, which is convenient for observation and operation.The equipment that needs to be installed in the warehouse and put into the warehouse shall be installed in place or placed in an appropriate position in the warehouse; The wall warehouse board shall be installed from the corner of the warehouse body, and the professional cold warehouse shall be installed. The cold warehouse shall be installed. The cold warehouse shall be constructed. The fruit fresh-keeping cold warehouse and medical cold warehouse shall have high pressure rating good waterproof performance, strong overload capacity, corrosion resistance, radiation protection and long service life. The corner shall be temporarily fixed with . color plate angle steel; When installing each wall panel, evenly apply two layers of foaming material on the joint surface of male and female groove, and apply one layer of foaming material when installing polystyrene wall panel. The blanking shall be uniform and continuous; After the wallboard is installed in place, pull rivets at the lap joint of the internal and external steel plates of the two wallboards for connection and fixation, the eccentric hook shall be loosened once before installation to ensure reliable locking during installation.Kurnawaka,The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.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.Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction), the size changes often reflect bubble cracking or falling off, and these will inevitably affect the normal use of cold storage. In addition to regular simulation of performance testing, more emphasis is placed on the selection of high quality materials: special energy polyether compound use, so that the foam body mesh structure, greatly improving the foam low temperature resistance. At present, polyether commonly used in spraying materials contains a large number of functional components, and a large number of linear structures formed after reaction are difficult to be stable at low temperature; The use of the energy crosslinking agent also greatly improved the dimensional stability of the foam. The selected polyether adopts catalysis in the production stage, and the reaction is complete, so that the polyether maintains a high reaction rate (that is, it can react completely with black material); Some manufacturers in order to achieve foam appearance does not produce deformation phenomenon and add a hole component to foam material, reduce the bubble closed hole rate, achieve the effect of stable size, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.
