Recently, experts from some scientific research institutes and engineering management departments in Taiyuan pointed out to reporters that energy saving should start from scratch. A small technological transformation project may produce immeasurable energy saving effect.
I've never in the energy consumption of fans and water pumps can be overlooked, there are about 40% wasted every year, its power consumption is about the national total electricity consumption 30%, calculated in accordance with the saving of 30%, every year can save 10%. In 2003, the national power generation was 1 trillion and 900 billion kwh, and the annual average power generation of Gezhouba Dam power plant was 15 billion 700 million kwh. According to this calculation, only one year's energy saving of the fan and water pump is equivalent to the power generation of 10 Gezhouba Dam power plants. In fact, most fans and pumps can achieve the purpose of saving energy through simple technical changes. The director of the Shanxi analysis and testing center, Ho Kai, said.
The head of the Taiyuan Municipal Engineering Administration Department of facilities told reporters: the total energy consumption of street lamps in Taiyuan city is about 14000000 yuan per year. If the energy saving device is installed, it will save 30% of electricity. The city can save 5 million yuan per year only by lighting one of the street lights. According to this calculation, the more than 300 large and medium-sized cities in the country can save more than 1 billion yuan of electricity bills every year.
At the beginning of this year, with the help of Shanxi Automation Research Institute, the Binhai hotel in Taiyuan installed a frequency converter to save electricity on the central air conditioner, which greatly saved the electricity consumption, and the energy saving benefit has already appeared. Hu Anmin, the marketing manager and senior engineer of Shanxi Automation Research Institute, who is responsible for the project, said that since the installation of energy saving equipment, the output power of motor has decreased from 75KW to 45KW, saving 30 kilowatt hour per hour, saving electricity by 15 yuan, and saving more than 1 yuan in electricity in that month. The price of a set of inverters is 70 thousand yuan, and the investment can be recovered in half a year. After that, it can save 130 thousand yuan in electricity every year, which does not include the cost of diesel fuel saved during motor operation.
