China FAMOUS Steel Engineering Company Company News

From the perspective of market demand for cold storage, my country's existing cold storage capacity is still very insufficient. The United States currently has 22 million tons of cold storage, which is nearly 3.3 billion cubic feet. my country now has 9 million tons of cold storage, and China’s population is five times that of the United States. China’s future demand for cold storage is huge. Regarding the future development of China's cold storage, we can refer to and learn from the existing operation mode and development path of foreign cold storage. There are many public cold storages abroad, and users adopt the form of lease. The expansion of cold storage construction can effectively save costs. The development trend of cold storage is mainly manifested in the following aspects.   Construction scale Fruit and vegetable production areas should focus on the construction of controlled atmosphere cold storage, and the scale should be a combination of large, medium and small, and it is appropriate to develop medium-sized. The construction of mechanical air-conditioning warehouses should be optimized to promote prefabricated production, on-site assembly mode cold storage engineering chemical industrial products, fruit and vegetable production areas are suitable for building single-layer cold storage and small and medium-sized cold storage; promote plastic film, large sheds, large tents, silicon windows, small plastic films Air conditioning facilities such as packaging are the focus of my country's recent development. In cities with more developed economies, develop medium-sized cold storage and establish wholesale markets for frozen food storage. Open small and medium-sized cold storage to the society, and provide paid warehouse services, information services, and operational logistics services.   Cold Chain Logistics my country's complete and independent cold chain system has not yet been formed, and the degree of marketization is very low. If conditions permit, freezing and cold storage enterprises can be transformed into distribution centers of chain supermarkets, forming a joint operation model of freezing and cold storage enterprises, supermarkets and chain operation enterprises. Establish a food refrigeration supply chain, purchase, process, store, transport, and sell perishable and fresh food from the place of production to consumers in all links in a standard low-temperature environment to ensure the quality of food and reduce unnecessary To prevent food deterioration and contamination.   Refrigeration equipment The refrigeration equipment industry should focus on the development of the international market’s advanced and universal split or integrated automation units of all grades below 60HP and equipped with electronic technology. Computers and automation technology should be widely used in the automatic control of the entire refrigeration system for the purpose of refrigeration. The refrigeration industry is upgraded and upgraded, the industrial chain is extended, and the project cost is reduced.   Overall plan The cold storage industry must strengthen overall planning and coordination under the unified coordination of relevant departments, and vigorously develop the construction of the cold chain logistics system. At the same time, it is necessary to prevent blind duplication of construction to ensure the sustained, healthy and stable development of my country's refrigeration and refrigeration industry.

What are the classifications of cold storage? (1) According to the scale of cold storage capacity At present, the division of cold storage capacity is not unified Divided by capacity, the cold storage capacity of large-scale cold storage is above 10,000t; the cold storage capacity of medium-sized cold storage is 1000～10,000t; the cold storage capacity of small-scale cold storage is below 1,000t. (2) According to the design temperature of refrigeration It is divided into four types of cold storage: high temperature, medium temperature, low temperature and ultra-low temperature. ①The cold storage design temperature of general high temperature cold storage is -2℃ to +8℃; ②The cold storage design temperature of medium temperature cold storage is -10℃ to -23℃; ③Low temperature, the temperature is generally -23℃ to 30℃; ④Ultra-low The temperature of the quick-freezer is generally -30℃ to -80℃. (3) According to the category of library body structure 1. Civil cold storage: The outer structure is civil construction, which is completed through civil construction. The installation period is long; due to the large thermal inertia, the temperature of the cold storage is less affected by external interference; due to technical reasons, the early cold storage mostly adopts this structure. 2. Combined cold storage: Also called prefabricated cold storage. The maintenance structure adopts light steel structure, or the library body is directly installed indoors. The installation cycle is short, the cooling speed is fast, and the appearance is beautiful. If necessary, it can be disassembled and quickly reassembled. At present, even large-scale cold storage is also adopting this form. Combination cold storage is a trend in the development of cold storage. (4) Divided by purpose Cold storage has a wide range of uses, so there are many divided by use. But in the final analysis, it is divided by function, that is, divided by structure and temperature.

BIPV stands for Building Integrated PV, which is the integration of photovoltaic buildings. PV stands for Photovoltaic. BIPV technology is a technology that integrates solar power (photovoltaic) products into buildings. Building Attached PV (BIPV) is different from the form in which the photovoltaic system is attached to the building (BAPV: Building Attached PV). In modern society, people's pursuit of a comfortable building thermal environment is increasing, leading to increasing energy consumption of building heating and air conditioning. In developed countries, building energy has accounted for 30%-40% of the country's total energy consumption, which has restricted economic development to a certain extent.   Advantage Architectural Aesthetics BIPV building is first of all a building, it is an architect’s artwork, and the key to its success is the appearance of the building. In BIPV buildings, we can hide junction boxes, bypass diodes, connecting wires, etc. in the curtain wall structure through related designs. In this way, it can prevent direct sunlight and rain erosion without affecting the appearance of the building, achieving a perfect combination with the building and realizing the ideas of the architects. Building lighting For buildings, light is the soul, and its requirements for light and shadow are very high. The BIPV building is a double-sided glass component made of smooth super white tempered glass. It can achieve a specific light transmittance by adjusting the arrangement of the cells or using perforated silicon cells, even in the sightseeing areas of the building. Transparency requirements. Of course, the greater the light transmittance of the photovoltaic module, the thinner the arrangement of the cells and the smaller the power generation. Safety performance BIPV modules not only need to meet the performance requirements of photovoltaic modules, but also meet the requirements of the three experimental requirements of the curtain wall and the safety performance requirements of the building. Therefore, it needs to have higher mechanical properties than ordinary modules and adopt different structural methods. In different locations, different floor heights, and different installation methods, the mechanical properties of its glass may be completely different. The double-glass photovoltaic module used in BIPV buildings is composed of two pieces of tempered glass, the middle is composed of PVB film composite solar cells to form a composite layer, and the cells are connected in series and connected in parallel to collect the lead ends as an integral component. The thickness of the tempered glass is the result of strict mechanical calculation in accordance with the national building code and curtain wall code. The PVB film in the middle of the module has good adhesion, toughness and elasticity. It has the effect of absorbing impact and can prevent the impact from penetrating. Even if the glass is broken, the fragments will firmly adhere to the PVB film and will not fall off. Injury to people, so that the damage may be reduced to a minimum and improve the safety performance of the building. Easy to install BIPV building is a close combination of photovoltaic modules and glass curtain wall. Since the development of curtain wall in our country for 30 years, various types of curtain wall have relatively mature design and installation technology. The component-type curtain wall has flexible construction methods, strong adaptability of the main structure, and mature technology. It is currently the most used structural form. The unit curtain wall is processed in the factory, which is easy to realize industrialized production, reduces labor costs, and controls the quality of the unit, thereby shortening the construction period and bringing greater economic benefits to the owner. The double-layer ventilated curtain wall system has the advantages of ventilation, heat insulation and sound insulation, energy saving and environmental protection, and can improve the heat dissipation of BIPV modules, lower the temperature of the cells, reduce the efficiency loss of the modules, and reduce the heat transfer to the room. To put it simply, BIPV building uses BIPV photovoltaic modules to replace ordinary tempered glass, and its structural form is basically compatible with traditional glass curtain walls. This makes the installation of BIPV photovoltaic modules have a deep technical foundation and advantages, and can fully meet the requirements of convenient installation. Long life The glue used for the encapsulation of ordinary photovoltaic modules is generally EVA. As the anti-aging performance of EVA is not strong and the service life is less than 50 years, it cannot be the same life as the building and the yellowing of EVA will affect the beauty of the building and the power generation capacity of the system. The PVB film has the characteristics of transparency, heat resistance, cold resistance, humidity resistance, and high mechanical strength, and has been maturely used in the production of laminated glass for construction. The domestic glass curtain wall specification also clearly puts forward the "application of PVB" regulations. BIPV photovoltaic modules use PVB instead of EVA to achieve a longer service life.
