The general knowledge of household appliances energy saving: The TV's brightest is 45% higher than the darkest energy consumption

With the rapid development of our country’s economy, household appliances have entered millions of households, and the popularization and application of various home appliances has improved our quality of life. While we enjoy our lives, the consumption of household electrical appliances has become one of the major aspects of energy consumption. Therefore, the energy saving and power saving of home appliances have naturally become a topic of concern. Especially in the midst of a tight supply of electricity in the summer, the energy saving of household appliances becomes more and more important. The following are some common household appliances energy-saving techniques.

1. Energy-saving lamps and lanterns use high-efficiency energy-saving lamps to improve energy efficiency. According to calculations, if all the lighting fixtures in our province use energy-saving lamps, the electricity saved in a year can reach more than 7 billion kilowatt hours, and we need to develop a convenient shutdown. The lamp habit reduces electricity consumption. At the same time, when the lamp bulb accumulates, the luminous flux may fall below half of the normal value. When the lamp, lamp, or wall is not clean, the reflectivity and light transmittance will be greatly reduced. To ensure lighting effects, the bulbs, lamps, and walls should be cleaned regularly.

2. Refrigerator refrigerators are one of the main energy-consuming appliances. Taking a 200-liter refrigerator as an example, energy-saving refrigerators can save more than 0.5 kWh per day than normal refrigerators, and can save 1,800 kWh in 10 years. Therefore, the Using an energy-saving refrigerator is the best way to save energy in the refrigerator. Summer is the season when the refrigerator consumes the most electricity. The following points should be taken into consideration when saving the refrigerator: The refrigerator should be placed in a cool and ventilated place as much as possible. The left and right sides of the refrigerator must have a space of 10-20 cm to ensure good heat dissipation. Electricity consumption; refrigerated foods should not be placed too full, too dense, the amount of 80% of the refrigerator volume is appropriate, leaving gaps conducive to cold air circulation; regular defrost, cleaning the condenser and the box surface dust; reasonable set of refrigeration And the temperature of the freezer, refrigerated temperature is set to 3 °C more than twice the monthly power consumption of 8 °C set, and the effect of preservation is poor, the freezer temperature -14 °C than -18 °C power saving more than 2%; frozen food Before serving, it can be thawed in advance in the freezer, so that the thawed cold can be fully utilized.

3, TV power-saving does not see when trying to unplug the power plug, when the TV is plugged into the power supply, it will preheat the picture tube, power consumption above 5W; TV brightness should not be too bright, the brightest than the darkest energy consumption 45% higher Above, but too bright for the eyes is not good; the volume should not be too large, because each increase of 1W of audio power will increase the power consumption of 3-4W; make good use of the remote control, a short time when not watching, turn off the remote control, long time When not looking, turn off the power.

4, rice cookers save electricity can be washed rice in the pot soak for 30 minutes, and choose warm water cooking, can save 30% energy, in addition, if the pot covered with a towel, you can reduce the heat 20%, more Cook the rice quickly; in addition, clean the electric dish of the rice cooker and the bottom of the pan because dirt can affect the heat transfer effect and increase power consumption.

Other household appliances, such as hoods, need to be regularly cleaned. Oil plugging filters will increase power consumption by more than 1 time; scale on electric heating pipes in electric kettles should be promptly removed; and the speed of electric fans should be reasonably selected because speed is directly proportional to power consumption.
