  • What is the future of HVAC market in the next half year of 2021
    What is the future of HVAC market in the next half year of 2021
    In 2021, central air conditioning will have greater breakthroughs in industries like: data centers, rail transit, medical industries and industrial manufacturing. 2020 is a special year of ups and downs.  After a hard year, with the normalization of epidemic prevention and control, the social order has gradually entered the right track. There are also small and medium-sized projects and in addition to the relatively large impact of the light commercial market, the construction process of large-scale projects has obviously recovered faster, coupled with the country’s "new infrastructure" and other favorable policies to stimulate the application market one by one. It has also brought significant changes to the central air conditioning segment application market. In air-conditioning of the huge application market, this year's data center, rail transit, medical industry and industrial manufacturing deserve our focus. Data center: Judging from the market launch plans of well-known companies, Tencent Cloud and Alibaba Cloud alone intend to invest more than 400 billion in the construction of data centers in the next three years. News such as China Mobile's development of 5G data centers across the country are stimulating the industry to flourish Development. At the same time, the industry's power consumption has also attracted attention. Intelligent operation and green efficiency will become the mainstream trend of this industry. Rail: Urban rail transit, as a key development project in my country, has gained significant growth vitality. Local governments continue to renew and improve infrastructure to further reduce costs and improve operational efficiency. The next ten years will still be the peak period for my country's urban rail transit investment and construction. The development of air-conditioning manufacturers is of great benefit. Medical industry In the past year, the medical industry has developed rapidly. It includes unconventional measures that have been explored due to the spread of the epidemic, as well as planned expansion and new projects. HVAC equipment is a must for high-efficiency and energy-saving hospitals and optimizing the respiratory environment. Factors have become the focus of the game for the main players in the market. Similarly, the air-conditioning cold and heat source system accounts for more than half of the total energy consumption in the entire medical air-conditioning system. Industrial manufacturing In 2020, the national industrial added value above designated size will grow by 6.9% year-on-year. In three categories, the mining industry will grow by 3.5%, the manufacturing industry will grow by 7.5%, and the production of electricity, heat, gas and water will increase by 4%. China is in the industry during the special period of the transformation of a large country into an industrial power, high energy consumption has always been the obstacle to the transformation, and the central air conditioner, as a large ene...

    How to design a sewage source heat pump with the longer life span ? Evaporator and condenser matters a lot
    Do you know what is the most important parts on a sewage source heat pump to affect its life spam?Of course it must be the evaporator and condenser quality. Because the heat exchange tube selection directly affects the cost and service life of the heat pump unit. The sewage source heat pump evaporator and condenser are usually used in an environment containing chloride ion corrosion. The heat exchanger tube is corrosion resistant. Performance is particularly important. The commonly used heat exchange tube materials include various duplex stainless steels (such as 2205, 2507, etc.), copper-nickel alloys (B10, B30), and so on. Their respective characteristics are as follows: B10 has better resistance to chloride ion corrosion, and the corrosion rate of B10 is lower than 0.03mm/a. With the increase of time, the average annual corrosion rate is getting lower and lower. And the corrosion resistance does not change much within 50 ℃. However, B10 is not resistant to erosion and corrosion, and its corrosion resistance is greatly reduced in a sandy water environment. The maximum permissible sea water velocity of B10 can refer to the British Naval Ship Engine Code. Therefore, when choosing B10 as the material of the heat exchanger, the following points should be paid attention to: (1) The flow velocity of the B10 nickel-copper pipe should be controlled, and should not exceed 1.5m/s, especially the influence of impurities such as mud and sand should be considered. (2) B10 nickel-copper pipes and fittings should be butt connected by manual argon arc welding. (3) In order to make B10 nickel-copper pipe form a complete protective film corrosion product film in seawater and ensure the expected service life of B10 nickel-copper pipe, before butt welding, B10 nickel-copper pipe and fittings must be cleaned of oil on the pipe end. One is to ensure the welding quality, and the other is to avoid the formation of a local carbon film in the tube. B30 is also an excellent seawater heat exchanger material. Under the same corrosive conditions, its corrosion rate is about 1/3-1/2 of B10; B30 also has the problem of not being resistant to erosion and corrosion. The precautions are the same as those of B10; The upper limit of the flushing rate is higher than that of B10. In general design, the water flow rate of B30 does not exceed 3m/s. Both 2205 and 2507 have good corrosion resistance. When the chloride ion concentration is 1100mg/lL, 2507 will not cause pitting and crevice corrosion. Due to the large relationship between corrosion and temperature, 2205 has a risk of crevice corrosion when the chloride ion concentration is 1100mg/lL and the temperature is higher than 32°C. Therefore, if 2205 is used as the material of the heat exchanger, measures should be taken to eliminate the gaps between pipe connections and intercrystalline gaps (for example, screw connections are not used in the project, and non-metallic gaskets between flanges are used to prevent intercrystalline g...
