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.

Recently, Dongfeng Motor released the Dongfeng Passenger Vehicle brand under the slogan of “Pride Forward†in Shanghai. The brand includes three sub-brands: Dongfeng Fengshen, Dongfeng Fashion and Dongfeng Fashion. The Dongfeng Style is Dongfeng Zhengzhou Nissan's new brand name. This move indicates that the Dongfeng passenger car brand under the strategic guidance of Dongfeng Company's self-reliance, large-scale cooperation, and large-scale development, is accumulating the brand's polynuclear, fusion, announced the development direction of the Dongfeng passenger car brand, one for the future The international brand has been clearly visible.
As early as in 2007, Dongfeng Motor Co., Ltd. set out from the strategic height of building “three east winds†and fully devoted itself to the development of autonomous passenger vehicles. Dongfeng Passenger Vehicle Company should be born from time to time. In July 2011, Dongfeng Motor Co., Ltd. proposed its own independent strategy. In December, it announced its own brand business plan, namely the “Dry†D300 program; in July 2012, it confirmed the Dongfeng Passenger Vehicle brand and its three sub-brands, Dongfeng Fengshen, The Dongfeng passenger car brand logo will be released in September.
Since 2011, the status of Dongfeng brand passenger vehicles in its own brand has risen rapidly. Sales volume has jumped from No. 9 to No. 7 in 2012, and the year-on-year increase has remained above 40%, which is in stark contrast to the micro-growth situation. 2013 In the first quarter, the Dongfeng brand passenger car sold 82,000 vehicles, achieving a year-on-year growth of 40.2%, ranking first among the three major central-level car brands.
Dongfeng's "Twelfth Five-Year Plan" has determined the strategic goal of "strengthening excellence, building the strongest, world-class automotive manufacturers". The core of the plan will focus on the breakthrough of self-owned brands. The "Dry" D300 plan not only represents the pre-judgment of the large auto group in China for the future auto market, but also clearly defines the future business growth point of Dongfeng Motor. The goal of the “Dry†D300 project is: By 2016, the sales of Dongfeng Motor’s own brands, including commercial vehicles and passenger vehicles, will reach 3 million, including 1 million Dongfeng-brand commercial vehicles and 1 million Dongfeng-brand passenger vehicles. One million brand cars.
