Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface, that is, the top and wall are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, while the ground needs to be insulated separately. At present, the common operations in the market are: laying the ground with XPS extruded board, laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively, and then pouring concrete or reinforced concrete.No matter whether the food cold storage or quick-frozen storage is in use it is inevitable that there will be various small faults. Don't be nervous when there are problems. You can find or eliminate problems according to the knowledge taught today.leon,Selection of refrigeration unit in cold storage: the selection of cold storage system software is mainly the use of refrigeration compressor and air conditioning evaporator in cold storage.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.Eden,According to the size and nature of the cold storage area and in combination with local regulations, the construction form of food cold storage warehouse is to determine the plane layout based on the site,leonInstallation of fruit and vegetable fresh-keeping cold storage, whether it is a single-layer or double-layer warehouse and the structure is the selection of steel structure or reinforcement solidification. Cold storage capacity, production process, refrigeration, product stacking, etc. are used to determine the size and location of the cold storage room, so that it can become a whole.Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor, fan and other equipment. In case of abnormal sound, timely warranty is required, so as to avoid greater damage to the compressor due to untimely warranty.During the installation of cold storage board in 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.
Strong deformation resistance, not easy to crack, smooth, stable and safe. Polyurethane material has stable porosity structure and basically closed pore structure. It not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption performance. Under normal service and maintenance conditions, the life expectancy of rigid foam polyurethane insulation can reach more than years. During the structural life period, wet or electric corrosion under normal service conditions, while the unit price of insect, fungus or algae foam material is higher than other traditional insulation materials,leonMedical cold storage, sometimes two defrosting schemes are adopted, and sometimes different schemes are combined. For example, the shelving, wall and top smooth pipes of the controlled atmosphere storage can be manually combined with the hot gas method. The frost can be manually swept at ordinary times, and the hot gas defrosting can be carried out regularly, so as to thoroughly understand the frost that is not easy to be removed by manual sweeping and the oil accumulation in the pipeline. Cold fan water flushing and hot gas method. Hot air combined with water can be used for defrosting if there is a lot of frost and the controlled atmosphere storage needs to be defrosted frequently.For water-cooled units, the turbidity of cooling water shall be frequently, the cooling water shall be replaced frequently, and whether the running, emitting, dripping, leakage and other conditions of the water supply system exist.Latest consultation,Stretch perlite: stretch perlite is a kind of granular material with porous layout. The gap in it blocks out the heat. Professional cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage, strict testing,leonPreservation technology of vegetables in cold storage, quality assurance. Preferential activities are in progress. Welcome to consult. It has a good heat insulation effect. Then the water vapor in the cold storage is easy to condense, and the water absorption of extensional perlite is particularly strong. If it absorbs a lot of water, its nature will be greatly reduced. Therefore, it is necessary to be careful to select extensional perlite as 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, height and warehouse temperature of the cold storage on the basis of safety, science and rationality, from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.
Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation,Proper protective measures shall be taken during transportation to prevent plate from being strangled and scratched.The warehouse shall be equipped with emergency lighting, door lock opening and alarm devices, which can save themselves or call the police for help.The refrigeration of cold storage pays more and more attention to the needs of environmental protection and energy saving. Professional projects include: cold storage installation, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other related businesses. Merchants who hope to have this business please consider the wide scale of warehouse temperature control, the selection and placement of cooling equipment and the description of wind speed field, which are suitable for the cold storage needs of a variety of goods. Equipped with perfect storage temperature active detection, recording and active control equipment.leon,Here we focus on polyurethane. Polyurethane is an ideal cold storage material in the cold storage project. Superior bonding properties make the foam and metal panels form a solid whole, so that no other adhesive materials are needed. When polyurethane is used as a cold storage project, rigid polyurethane foam is formed between the panels of the storehouse panel, and then solidified and pressed to form a multi shape storeboard, because the metal plate can roll out different waveforms, so that the overall rigidity is stronger and the bearing capacity is higher. Polyurethane filler board can meet the firmness and physical requirements of exterior wall and can be used in various cold storage projects. It is technically feasible and cost-effective. Yuanbao refrigeration believes that polyurethane is one of the new cold storage materials with great development prospects in the future. The thermal insulation materials of cold storage engineering should not only have good thermal insulation performance, but also be economical, applicable and environmental friendly. To ensure the smooth progress of our cold storage project, we should not only inquire about the raw materials of the cold storage, but also the types of cold storage. The common cold storage plates mainly include the following types namely stainless steel plate, color zinc steel plate, salted steel plate, embossed aluminum plate and mm galvanized standard floor plate.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.With the rapid development of modern commerce, the original cold storage for the purpose of product storage can no longer meet the rapid, accurate and small batch circulation needs of modern commodities. Therefore, the logistics center cold storage cold chain for the purpose of product distribution came into being and developed rapidly, playing a more and more important role in the commodity circulation chain. What are the characteristics of the rapid development of cold storage construction?
