Common sense of saving electricity

First, the plug and socket of household appliances should be in good contact to save electricity, otherwise it will increase power consumption and may damage electrical appliances.

Second, the scale accumulated in the electric heating tube of the electric kettle should be removed in time to improve the thermal efficiency, prolong the service life and save electricity.

Three, the use of electric heaters in the room should be sealed as much as possible to prevent heat loss. Turn off the power supply in time after the room temperature meets the requirements.

Fourth, it is best to buy an electric iron with a power of 500W or 700W for ironing clothes. This kind of electric iron heats up quickly, so long as it reaches the use temperature.

Automatic power off not only saves electricity, but also ensures the quality of ironing clothes.

5. If the fabrics of the ironed clothes are not exactly the same, iron them with low-temperature resistant chemical fiber clothes first, and then iron them with high-temperature resistance after the temperature rises.

Cotton and linen fabric. After the power failure, you can use the waste heat to iron some chemical fiber clothes.

6. The power consumption of the electric fan is directly proportional to the rotating speed of the fan blades. On the premise of meeting the use requirements, try to use the middle and slow gears. Such as 400 mm.

Fan, the fast gear consumes 60W, and the slow gear only consumes 40W.

Seven, for air conditioning, it is advisable to set the room temperature at 27 to 28℃. In addition, when turning on the air conditioner, close the doors and windows; Cleaning the dust screen regularly can save money

30% of electricity; Do not start frequently. After stopping, it must be restarted after 2 to 3 minutes.

1, TV When you use TV, whether it is a color TV or a black-and-white TV, the brightness should not be too bright, and the volume should be as low as possible without affecting the 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. Unplug the power plug after shutdown. 2. The power amplifier saves electricity mainly by reducing the volume, and the impedance of the external speaker should not be too small.

Avoid the combined use of multiple speakers, reduce the load of the power amplifier as much as possible, and achieve the purpose of saving electricity and protecting the machine. 3. Pay attention to the refrigerator, and don't push the food in the refrigerator too full or too dense, otherwise it will hinder the circulation of cold air and cause the refrigerator not to cool.

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, and defrost in time except frost-free refrigerators.

Pay special attention to dust the condenser regularly, so as not to affect the refrigeration effect and waste electricity. 4, washing machine clothes as much as possible.

The clothes washed in the washing drum should be close to the maximum laundry amount, so as to reduce the throwing times and improve the work efficiency. If the washing machine has been used for more than 3 years, it is found that the washing is weak, and the motor belt of the washing machine should be replaced or adjusted to make it moderately tight.

Lubricating oil should be added to the place where the washing machine needs to be oiled every once in a while to ensure good operation and achieve the purpose of saving electricity. 5. rice cooker rice cooker is a kind of rice cooker with high power consumption.

Because of its excellent heat preservation performance, when cooking food in an electric rice cooker, when the water in the cooker boils, the power supply can be cut off and the waste heat can be used for heating 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. Electric iron 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 master the temperature and cut off the power supply immediately when you reach the temperature required by the cloth. If thermal insulation is needed, a 3-amp, 400-volt rectifier diode can be connected in parallel at the switch, and it will heat normally 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. 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, thus achieving the purpose of saving electricity and protecting the motor. 8. For household lighting, try to use energy-saving lamps with high brightness and low power.

At present, the energy-saving lamps promoted generally can save electricity by about 20% to 70%. However, we must use qualified high-quality energy-saving lamps produced by regular manufacturers, and we must not be greedy and 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.

3. Common sense of saving electricity

In order to help you save electricity in the most scientific and reasonable way and really save electricity without affecting your normal life, we specially put forward some suggestions on saving electricity. Let's start from the family, ourselves and around us.

(1) Adjust the thermostat knob of the refrigerator. In summer, the indoor temperature changes greatly day and night, so it can be adjusted to "1" before going to bed, and then turned back to "4" during the day. At the same time, the refrigerator should be placed in a cool and ventilated place to ensure the heat dissipation of the radiator.

(2) Increase the air conditioning temperature by 65438 0℃. Generally, it is advisable to set the temperature at 28℃. For example, if the temperature of air conditioner is increased by 1℃, it can save about 0.5 degrees of electricity when running for 10 hour, and the sleep function of air conditioner can save 20% of electricity.

(3) Make full use of the waste heat of the rice cooker. When cooking, the pot is boiling, and the power supply will be cut off as soon as the key is lifted. Using the waste heat of the electric heating plate, press the button after a few minutes, and the rice cooker will automatically cut off power after cooking.

(4) The use of electric water heaters should try to avoid the peak hours of electricity consumption. In summer, you can turn down the thermostat and replace the bathtub with a shower, which can reduce the cost by two-thirds.

(5) Use more energy-saving lamps. If incandescent lamps are replaced by energy-saving lamps, the electricity consumption can be reduced to one-fifth of the original under the same brightness.

(6) Household appliances should not be in standby state. For example, household appliances are in standby state, and power consumption hurts the machine; The brightness of the TV can be lowered appropriately, which can save electricity and make the eyes less tired.

1, TV When you use TV, whether it is a color TV or a black-and-white TV, the brightness should not be too bright, and the volume should be as low as possible without affecting the audio and video.

5. What are some tips for saving electricity in life?

1. It is suggested that the air conditioning temperature should be set at 26-28 degrees Celsius in summer and 16- 18 degrees Celsius in winter. In summer, the air conditioner is raised 1 degree Celsius. If you turn on 10 hours every day, the air conditioner of 1.5 can save 0.5 degrees of electricity.

2. During the use of the air conditioner, the indoor filter should be cleaned at least once a month; If possible, please ask professionals to clean the heat exchange fins of indoor and outdoor units regularly.

3. There should be proper ventilation space around the refrigerator, away from heat sources and avoid direct sunlight. According to the season, the refrigerator temperature control file is raised in summer and lowered in winter. It is necessary to clear the frost on the refrigerator in time.

Food should be cooled to room temperature before being put in the refrigerator. Fruits, vegetables and other foods with more water should be washed and drained, wrapped in plastic bags and put in the refrigerator.

It is advisable to store about 80% food in the refrigerator. When the food is stored too little, the heat capacity becomes smaller, and when the food is stored too tightly, it is not conducive to the circulation of cold air, which will increase the number of starts and running time of the compressor.

6, focus on washing clothes, a small number of small clothes can be washed by hand; Using a proper amount of high-quality low-foam detergent can reduce the number of rinsing; Soak dirty clothes for about 20 minutes before washing; According to the type, texture and weight of clothes, the water level is set, and the washing time and rinsing times are set according to the degree of dirt, which saves electricity and water.

7. When using the vacuum cleaner, choose the appropriate power gear according to different situations; Filter bag dust removal can reduce airflow resistance, improve dust collection efficiency and reduce power consumption.

8. Removing the scale of the electric heating tube in the electric kettle can improve the heating efficiency and prolong the service life. In order to keep warm for a long time, domestic electric drinking fountains consume a lot of electricity. It is recommended to use the traditional thermos bottle, which has good insulation effect.

9. You should choose a temperature-regulating electric iron, which heats up quickly and will keep constant temperature after reaching the set temperature. When ironing clothes, you can iron those with low temperature resistance after electrifying, iron those with high temperature resistance after the temperature rises, and iron some with low temperature resistance after power off.

10. Two-thirds of the indoor heat and cold in residential buildings are lost to the outside through external walls and windows, which is directly related to the electricity consumption of air conditioners and the comfort of living. The state has mandatory regulations on the thermal insulation performance of houses, so you must pay attention to buying a house.

1 1. The brighter and louder the TV, the greater the power consumption. Turn on the 5-watt energy-saving lamp indoors, and adjust the volume and brightness of the TV set moderately, so that the viewing effect is good and it is not easy to make the eyes tired. Watching TV during the day and closing curtains to avoid light can reduce the brightness of TV accordingly.

12, the electric power and power consumption of electric fans with large fan pages are also high; The power consumption of electric fans is directly proportional to the rotating speed, and the power consumption difference between the fastest gear and the slowest gear is about 40%. In the case of meeting the requirements, choose an electric fan appropriately and enjoy the breeze at medium and low speed.

13. Coke bottles or salt bottles filled with water can be placed in the toilet water tank to occupy the volume of the water tank and reduce the washing water.

14, improve the utilization rate of water as much as possible, wash vegetables with rice washing water, and the water after washing vegetables can be used to water flowers; The water rinsed from the washing machine can be used as the next batch of washing water, and the last batch of washing water can be used to mop the floor, wash mops or flush toilets.

15. If the water temperature can't reach the required temperature during the shower, when discharging water, you can connect the cooler water into a container first, and the water can be reserved for other purposes.

16, it is best to concentrate on washing family clothes and reduce washing times, thus improving water use efficiency.

17, putting a proper amount of detergent in the washing machine will make it difficult to rinse clothes and waste a lot of water.

18, when cooking, the fire should be bigger at the beginning of cooking, and the flame should cover the bottom of the pot. But when the dish is ready, turn down the flame in time, minimize the fire when serving, and then turn up the flame until the second dish is ready, which not only saves gas, but also reduces the oil smoke pollution caused by empty burning.

6. The science of electricity, save electricity information, be concise and quick.

□ Power saving of washing machine

The power consumption of the washing machine depends on the length of use. The washing time depends on the kind of clothes and the degree of dirt. Generally, synthetic fibers and woolen fabrics need to be washed for 3 to 4 minutes. Cotton and linen fabric for 6 to 8 minutes; Extremely dirty clothes 10 to 12 minutes.

For the same long washing cycle, the leaves with weak washing rotate more times than those with strong washing, and the motor will be started repeatedly. The starting current of the motor is 5-7 times of the rated current, and weak washing consumes power instead; Forced cleaning can also extend the life of the motor.

When you have enough clothes, try to use the washing machine. Soapy water or washing powder foam on clothes should be wrung out (removed) and rinsed clean. Reduce the number of flushes.

Dehydration after washing can be completed within 2 minutes. Clothing dehydration 1, 680 rpm 1 min, the dehydration rate can reach 55%, and the dehydration rate is rarely improved by prolonging the time.

□ TV saves electricity

The brightest TV consumes 50% to 60% more power than the darkest TV; The louder the volume, the greater the power consumption. Adjust the brightness and volume appropriately. The standby energy consumption of remote-controlled TV sets is 6 watts to 8 watts, so it is necessary to manually cut off the power supply. Adding a dust cover can prevent the TV from inhaling dust, preventing electric leakage and affecting the image and sound quality.

As far as possible, frequency conversion air conditioner should be selected for air conditioning to reduce the number of restarts.

□ microwave oven saves electricity

The power saving of microwave oven mainly depends on the heating quantity and humidity of food. When heating food, add a protective film on the heated food to prevent water from evaporating from the heated food, which not only tastes good, but also saves electricity.

Removing the scale in electric heating tube of electric kettle in time can improve the thermal efficiency and prolong the service life.

□ rice cooker saves electricity

Choose the power of the rice cooker according to family needs. If there are stains on the surface of the electric heating plate and the bottom of the pot, they should be wiped clean or polished gently with fine sandpaper to improve the induction efficiency.

Make full use of the waste heat of the rice cooker. When cooking, you can turn off the power for 7 to 8 minutes after boiling, and then turn it on again. When you start eating, you can cut off the power.

□ Electric fan saves electricity

The power consumption of electric fans is directly proportional to the rotating speed, and the power consumption difference between the fastest gear and the slowest gear is about 40%. If it meets the requirements, try to use mid-range or low gear.

□ Lighting saves electricity.

Although the use of energy-saving lamps is expensive, it has high luminous rate, soft light, long life and low power consumption. 14 watt energy-saving lamp is equivalent to the brightness of 75 watt incandescent lamp, which can save electricity by 75%.

Keep bulbs and lampshades clean, and improve the luminous and reflective effects. Remember to turn off the lights when you leave the room. Users in peak and valley use household appliances after 10:00 at night to avoid peak and save money.

7. Power saving skills

There are many air conditioners in summer, and cleaning the filter once a month can save electricity 10% to 30%. The air conditioner consumes the most power when it is started, so it is best not to switch it on and off frequently. The set temperature should not be too low, which will increase power consumption. It is best to set it at 26℃~ 28℃ in summer and 16℃~ 18℃ in winter.

The optimum temperature for food storage in refrigerator is 8℃ to 10℃. It's best to unplug the TV when it's not watching. Standby 10 hour can consume half a kilowatt hour. Soak the rice cooker for 30 minutes before cooking, which can save electricity by 30%.

Before heating the food in the microwave oven, cover the container with plastic wrap, so that the water in the food will not evaporate, and the original flavor can be retained, the heating time is obviously shortened, and the power saving effect is obvious.

Air conditioning energy saving

Purchase air conditioners with an energy efficiency ratio of 2.45 or above or with the certification mark of energy-saving products in China. The energy efficiency ratio of air conditioners with the same power is increased by 0. 1, and 3%~4% of electricity can be saved.

The number of air conditioners selected matches the room size. 1 air conditioning is suitable for rooms of about 12 square meters, 1.5 air conditioning is suitable for rooms of about 18 square meters, 2 air conditioning is suitable for rooms of about 28 square meters, 2.5 air conditioning is suitable for rooms of about 40 square meters, and 3 air conditioning is suitable for rooms of about 50 square meters.

The outdoor unit should be installed in a place that is not exposed to direct sunlight. Using the sleep function or economical operation function of air conditioner can save electricity.

The standby power consumption of air conditioner with remote control function is about 8 watts. If the air conditioner is not used for a long time, the power supply should be cut off.

Lighting power saving

Although the use of energy-saving lamps is expensive, it has a long service life and consumes less electricity. 14 watt energy-saving lamp is equivalent to the brightness of 75 watt incandescent lamp, which can save electricity by 75%.

Reduce the wattage of the lamp holder or bulb in places where strong light is not needed, such as aisles. Remember to turn off the lights when you leave the room.

Refrigerator power saving

The refrigerator should be placed in a cool and ventilated place to avoid direct sunlight. The food in the refrigerator should be stored properly, leaving a gap for air conditioning convection.

Instead of putting hot food in the refrigerator, the frozen food to be eaten is melted in the refrigerator in advance to reduce the temperature of the refrigerator.

Defrost regularly, remove the dust on the surface of the condenser, and ensure the heat absorption and radiation performance of the refrigerator. When the frost layer thickness at the bottom of the freezer reaches about 4-6 mm, it must be defrosted.

Electricity saving of washing machine

The washing time depends on the type of clothes and the degree of dirt. For the same long washing cycle, "weak washing" consumes electricity instead, and "strong washing" can also prolong the life of the motor.

Try to use the washing machine when you have enough clothes to wash, and dehydrate within 2 minutes after washing. When clothes are dehydrated for one minute at the speed of 1680 rpm, the dehydration rate can reach 55%.

Electric fan saves electricity

The power consumption of electric fans is 5%~ 10% of that of air conditioners. The power consumption of electric fans is directly proportional to the rotating speed, and the power consumption difference between the fastest gear and the slowest gear is about 40%. If it meets the requirements, try to use middle gear or slow gear.

Electric rice cooker saves electricity.

Make full use of the waste heat of the rice cooker. When cooking, you can turn off the power for 7-8 minutes after boiling, and then turn it on again. When you start eating, you can cut off the power.

Television power saving

The brightest TV consumes 50% ~ 60% more power than the darkest TV. The standby energy consumption of the TV set with remote shutdown is 6~8 watts, and the power supply can be cut off manually.
