Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.
First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.
Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.
Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.
To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.

At present, the status quo of domestic auto parts companies is that they are small in scale, weak in strength, and lack of R&D capabilities. For example, Ningbo, which has the auto parts industry as one of the main pillar industries, owns more than 3,000 large and small parts companies, but most of them are not large scale, and the competitive advantage is generally dependent on cheap labor. The relevant person of Ningbo Automobile Parts & Accessories Association stated that although many products in Ningbo are gradually moving towards the high end, there are still many low-tech products in total, which are facing the pressure of overall transformation and upgrading. According to Chen Wenkai, president of Gasgoo.com, the development of parts and components will determine the development of the whole vehicle. China has become the world's largest market and automobile powerhouse, but facing the industrial transformation, only the core competitiveness of auto parts and components companies can be improved first. significance.
However, local auto parts companies have increased their technological capabilities through overseas acquisitions, and it has become increasingly clear that foreign companies have mastered the strategy of controlling key technologies and market conditions. After acquiring the global steering and transmission business of General Motors of the United States, Beijing Pacific Century Automotive Systems Co., Ltd. accelerated the accumulation of technology, talents, and experience and became a global leader in auto parts and components. In addition, BWI acquired a series of overseas acquisitions such as the Delphi brake and suspension business of the United States and Zhejiang Wanxiang’s acquisition of the steering shaft business of US auto parts companies.
“With regard to the core technology of owning key components, there is a large gap between domestic parts and components companies and international parts and components companies. However, it cannot be said simply that the technology content of products produced by private parts and components companies is low, and it took only 20 years for domestic auto parts to start. The start-up time of parts and components companies is also similar, and future parts and components companies must have the ability to co-develop new products together with OEMs, and this will be the way out. This is also the future market trend of parts and components companies. After the completion of our acquisition, we will invest. RMB 50 million to set up an R&D center in the UK to develop new technologies and new products,†Ma Zhicong told reporters.
Domestic parts and components companies go out of the country have advantages and disadvantages
At present, more and more domestic parts and components companies have gone abroad to acquire overseas companies. Industry analyst Xu Jinquan pointed out that on the one hand, the financial crisis and the European debt crisis have reduced the market demand for auto parts companies by European and American OEMs. These overseas spare parts companies are unable to obtain orders from OEMs and face operational difficulties; on the other hand, A few domestic parts and components companies have advantages in terms of scale. If they are further developed, they must break through the barriers to core technologies. Overseas mergers and acquisitions are a way of rapid development and can make up for shortcomings in a short period of time.
