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, 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.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?Kawasa Lake,However, not all controlled atmosphere reservoirs can choose to adjust with a large depth, which still needs to be determined according to the actual needs of fans and places. We can adjust the energy-saving effect of the control fan from the production design link, so that the energy-saving effect of the hot air fan will be significantly improved.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?Visby,In the process of realizing your dream, you must remove all the influences. It is very important to recognize that when these beautiful refrigerators are built in the villa room, the collection pit (pool) for flushing (thawing) and drainage should adopt the Countermeasures of avoiding freezing and cleaning and avoiding backflow of water.The cold storage belongs to a kind of refrigeration equipment. Compared with the refrigerator, its refrigeration area is large, but they have the same refrigeration principle. So how to maintain the cold storage every day. Today I'll introduce how to do a good job in the daily management and maintenance after the installation of the cold storage.The service life of the cold storage depends on the quality of the refrigeration equipment, but it also has a great relationship with the proper daily management and maintenance after the installation of the cold storage. Many times, people often ignore the latter point. In daily life, as long as we maintain and maintain the cold storage regularly, we can greatly improve the service life of the cold storage and reduce the cost.

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, 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.Advantages: no reciprocating motion, so it has the advantages of simple structure,Kawasa LakeFruit and vegetable fresh-keeping cold storage installation company, small volume, light weight, cold storage installation, cold storage construction, fruit preservation cold storage, low vibration, stable operation and low vibration of the whole machine; It has high efficiency and variable frequency speed regulation technology in the range of refrigeration capacity; The scroll refrigeration unit has no clearance volume, can maintain high volumetric efficiency, low operation noise, good stability and high safety, and is relatively not easy to liquid hammer.The height of the warehouse, the horizontal and vertical of the warehouse shall be designed according to the refrigeration, refrigeration equipment, transportation and stacking conditions. The selection of insulation board is very important for Guangdong cold storage. At present, the vast majority of cold storage use polyurethane insulation board. What are the characteristics and advantages of polyurethane insulation board?Fair price,Install the electric control system. The electric control system of the cold storage mainly includes electric controller, electric door, lighting and other electrical equipment in the cold storage. The power supply of the cold storage is required to be stable phase line, and the power supply or backup power supply can be used as required. The circuit shall have reasonable discharge and corresponding protective measures.In the low temperature environment, especially in the periodic freezing and thawing cycle, the building structure is also vulnerable to. Therefore, the building materials of the cold storage and the structure of each part of the cold storage should have sufficient frost resistance.Install the library body. Generally, 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.

Installation of cold storage, construction of cold storage fruit preservation cold storage and medical cold storage have stable, 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.Finance Department,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,Kawasa LakeInstallation price of cold storage, laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively and then pouring concrete or reinforced concrete.Before the warehouse is fixed with angle aluminum, it shall be sealed with glass glue and fixed with angle aluminum with solid pull Mao. The distance between pull rivets is mm. The distance between the upper and lower sides of the door is mm.The assembled cold storage body often adopts double-sided color steel plate of polyurethane thermal insulation material,Kawasa LakeCold storage installation design price, which has excellent thermal insulation performance, storage and circulation effect and reduces operation energy consumption. Of course, more important is the choice of refrigeration system. For example, at present, the refrigeration system of fluorine refrigerant is still the mainstream, but when selecting the type and power of cooling equipment, it is necessary to calculate the data for the installation of cold storage, and then make a high-quality choice.Kawasa Lake,The evaporator surface is too thick or too much dust, and the heat transfer effect decreases: another important reason is that the heat transfer efficiency of evaporator is low, which is mainly caused by excessive frost or excessive dust on the evaporator surface.Because polyurethane sheet has excellent thermal insulation performance, it can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.Insufficient refrigeration dose and capacity in the system: there are two main reasons for insufficient refrigerant circulation,
