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.

[Wuhan News] (Internship reporter Zhu Wei) Yesterday, the 6th Wuhan International Automobile Industry Exhibition ended.
According to the Organizing Committee, the total exhibition area of ​​this auto show is 35,000 square meters, equivalent to more than 2,300 standard booths. There are more than 90 types of finished vehicles, more than 360 exhibition vehicles and nearly 300 cars and automobiles. Participating parts and components manufacturers participated in the exhibition and the number of visitors was nearly 300,000. Regardless of the scale of the exhibition or the number of exhibitors, the Wuhan International Auto Show has become more mature. There is no shortage of premium cars worth about 1 million yuan. Citroen exhibited its top luxury cars C4 and C6 for the first time in Han. C6 currently sells for more than 600,000 yuan. Volkswagen has exhibited Phaeton at a price of one million yuan. The most expensive exhibitor is Lincoln, which sells for 1.68 million yuan.
Different from previous years, this year's auto show has emerged some new bright spots, such as the Dongfeng Group gathers at the auto show, the domestic first-line brands compete on the same stage, and the classic imported models complement each other. Dongfeng Group led the overall appearance of its Dongfeng Citroen, Dongfeng Honda, Dongfeng Nissan, Dongfeng Peugeot, Dongfeng Yueda Kia and other brands; FAW Toyota, Guangzhou Toyota, Guangzhou Honda, Changan Ford, Shanghai Volkswagen, SAIC General Motors, Beijing Hyundai and other domestic first-line car brands Also appeared in the show; as an imported brand and luxury car that reflects the taste and level of the auto show, it also added a lot to this auto show. Although the lack of traditional luxury car brands such as Mercedes-Benz, BMW's joining, but some subsequent brands into the Chinese market such as Volvo, Renault, etc. have been accepted for Wuhan consumers, Opel Astra GTC, Saab 9-3, Jeep commander, Citroen C6 and other high-end imported models have also attracted many people's attention.
However, it is somewhat regrettable that many consumers have long thought of the glory of the car models, such as the upcoming Dongfeng Peugeot New 307, Changan Ford New Mondeo, etc. did not appear in the auto show.
Zhongpeng Chi, a senior reporter of the China Automotive News, told this reporter that although the Wuhan International Auto Show has a long way to go compared to the Beijing Auto Show and the Shanghai Auto Show, the results held this year show that the Wuhan Auto Show is moving toward the mainstream. “This should be with Hubei. The continuous strength of the auto industry, the continuous improvement of the strength of the people's consumption, and the continuous expansion of the province's economic radiation have a lot to do.â€
