Energy saving information

Saving electricity means saving electricity. Saving electricity is not using electricity or using less electricity, but using electricity science. Take technically feasible, economical and reasonable measures to reduce the direct and indirect loss of electric energy and improve energy efficiency and environmental protection.

3, home power saving

1, TV, computer When you use TV, the brightness should not be too bright and the volume should be as low as possible without affecting audio and video. In addition, do not switch frequently. For some remote-controlled color TVs without AC shutdown function, the remote-controlled receiving part is still charging after shutdown, and the indicator light is on, which will consume some electricity. The standby state of computers and televisions also consumes a lot of power, so cut off the power supply in time when not in use. When the computer is in "sleep" mode, the power consumption is reduced to less than half. If it is turned off without unplugging, it still has 4.8 watts of energy consumption.

2. The power amplifier saves electricity mainly by reducing the volume, and the impedance of the external speaker should not be too small. Avoid using multiple speakers in combination, and reduce the load of the power amplifier as much as possible, so as to save electricity and protect the machine.

3. The refrigerator should pay attention to the fact that the food in the refrigerator should not be pushed too full or too dense, otherwise it will hinder the circulation of cold air and lead to the refrigerator not being cooled. There shouldn't be too little food in the refrigerator. If there is too little food in the refrigerator, it will lose air conditioning and waste electricity. Refrigerators should minimize the number and time of opening doors. Pay special attention to dust the condenser regularly, so as not to affect the refrigeration effect and waste electricity. There should be proper ventilation space around the refrigerator, away from heat sources, away from direct sunlight, and remove frost from the refrigerator in time.

4, washing machine clothes should be concentrated as much as possible. The clothes washed in the washing tub should be close to the maximum washing capacity, so as to reduce throwing times and improve work efficiency. If the washing machine has been used for more than 3 years, and it is found that washing is weak, the motor belt of the washing machine should be replaced or adjusted to make it moderately elastic. Every once in a while, lubricating oil should be added where the washing machine needs to be refueled to ensure good operation and achieve the purpose of saving electricity.

5. rice cooker rice cooker is a kind of rice cooker that consumes a lot of electricity. Because of its excellent thermal insulation performance, when cooking food, when the water in the pot boils, you can cut off the power supply and use the waste heat to heat it for a period of time. If the rice is not cooked, you can turn on the power again. In this way, intermittent power supply can save electricity by about 20% to 30%.

6. When using an electric iron, clothes should be ironed as intensively as possible, and the corresponding temperature control points should be selected according to different materials. If you use an ordinary electric iron that can't adjust the temperature, you should also know the temperature, and cut off the power supply immediately when you reach the temperature required for clothes. If thermal insulation is needed, a 3-amp, 400-volt rectifier diode can be connected in parallel at the switch, which will normally heat up when the switch is turned on; When the switch is turned off, the rectifier diode is connected in series with the circuit and enters the heat preservation state. The electric iron can save about 40% electricity in the heat preservation state.

7. Energy-saving of air conditioning: The ventilation pipes on air conditioning are easily blocked by pollutants, which reduces the refrigeration efficiency. After cleaning, the air volume can be increased by 10%, and the air conditioning temperature can be increased by 1 Celsius in summer, saving energy by about 10%. If the power of the household air conditioner is 1.5kW, and it runs for 5 hours every day, the power consumption of the air conditioner is 750 degrees. If it runs for 7.5 degrees every day and 100 days in summer, the air conditioner can save about 20%( 150 degrees). Therefore, it is best to clean the air conditioner before the arrival of summer. When installing the air conditioner, try to choose a cool place, or add a sunshade to the air conditioner to avoid direct sunlight. The shorter the connecting pipe between indoor unit and outdoor unit of split air conditioner, the better, in order to reduce power consumption, and the connecting pipe should be well insulated. ……

It is advisable to set the air conditioning temperature at 26 to 28 degrees Celsius in summer. Close the doors and windows when turning on the air conditioner, and don't open the door frequently to reduce the infiltration of hot air. When the air conditioner cools, the position of the air deflector is adjusted to the horizontal direction, and the cooling effect will be better. You can turn off the air conditioner 10 minutes before you leave home. When you turn on the air conditioner at night, turn off the refrigeration for an hour or two, and then turn on the electric fan to blow, so as to cool down and save electricity.

8. The power consumption of the electric fan motor is directly proportional to the load (that is, the blade size of the electric fan) and the voltage applied by the motor, and the voltage applied by the motor is directly proportional to the rotating speed. In other words, the larger the blade diameter, the higher the rotational speed and the greater the power consumption. Under the condition of basically meeting the air volume, try to choose an electric fan with smaller blade diameter. The electric fan should start at high speed, and then switch to medium speed or low speed after reaching the rated speed, which is beneficial to the speed start of the motor, so as to save electricity and protect the motor. The power consumption difference between the fastest gear and the slowest gear of electric fan is about 40%, so try to use low gear.

9. For household lighting lamps, try to choose energy-saving lamps with high brightness and low power. At present, the energy-saving lamps promoted generally can save about 20% to 70% electricity. But we must use qualified high-quality energy-saving lamps produced by regular manufacturers, and we must not be greedy for cheap, so as not to cause unnecessary losses to ourselves. Existing incandescent lamps in the home (including chandeliers, wall lamps, ever-burning lamps, etc.). ). If high brightness is not needed, rectifier diode (1 amp, 400 volts is lower than 100 watts; 100W, 300W, choose 2 amps, 400V), which can save about 40% electricity.

10, select energy-saving products.

Energy-saving products are generally more expensive than ordinary products, but from the perspective of the whole service life of products, energy saving is actually more economical. For example, the price difference between ordinary air conditioners and energy-saving air conditioners of the same specification is only a few hundred yuan. According to Xia Dong, this energy-saving air conditioner with a power of 2,500 watts and an energy efficiency ratio of 3.0 can save more than 520 degrees of electricity every year compared with the ordinary air conditioner with an energy efficiency ratio of 2.5, saving about 300 yuan. An ordinary 40-watt incandescent bulb is about 2 yuan, and an 8-watt energy-saving lamp with the same brightness is about 10 yuan. According to the calculation of lighting for 6 hours a day, energy-saving lamps can save 70 degrees of electricity every year, and their service life is 8 to 10 times that of ordinary lamps. Similarly, energy-saving refrigerators, washing machines, etc. Save a lot of electricity every year.

4 industrial energy saving

Compared with ordinary household electricity consumption, it is more important and urgent for industrial enterprises, which account for more than 70% of China's total electricity consumption, to save electricity. When electricity has become an indispensable energy source in our lives, these words related to electricity clearly tell us that electricity is in short supply.

Under the shortage, saving electricity is undoubtedly one of the effective ways to relieve the pressure. At present, China has entered a new round of economic growth, and has shown increasingly obvious characteristics of heavy chemical industry. China has become the world's largest consumer of coal and the second largest consumer of oil and electricity. Compared with the electricity consumption of ordinary people, industrial enterprises, which account for more than 70% of the total electricity consumption in China, have more practical significance in saving electricity.
