Worry about the electricity bill every month? Trying to find a way to save electricity backfires? In fact, a lot of home appliances can be used in a simple way to achieve the effect of saving electricity, to see how to reduce the household unnecessary power consumption.
Energy saving tips for common household appliances
1. Lighting
1. Fluorescent lamps save electricity than incandescent lamps: many families still continue the habit of using incandescent lamps, but they do not know that as long as a fluorescent lamp is replaced, the energy saving index can be greatly improved. At present, the better environmental protection and energy-saving products LED fluorescent lamp, 2 watts can replace 40 watts of incandescent lamps, 4 watts can completely replace 20 watts of ordinary fluorescent lamps and 20 watts of ordinary energy-saving lamps.
2. Appropriate installation height to improve illumination: installation height should be appropriate. (LED energy-saving lamp with 80% energy saving power) for example, if the 20 Watt fluorescent lamp is installed at 1 meter height, the illumination is 60 lux; if it is 0.8 meter high, it is 93.75 lux. If the height is properly lowered, the wattage can be reduced and the power consumption can be saved.
2. Air conditioning
Many people think that the increase in electricity charges in summer is mainly due to the increase of air conditioning. In fact, it is not unreasonable. After all, the power consumption of air conditioning is still a large part. Therefore, it is very important to know the power saving method of air conditioning.
1. Choose a reasonable temperature: air conditioning refrigeration state, every increase of 1 ℃ can save about 10% of electricity. In summer, you don't need to adjust the air conditioner too low. 25-27 ℃ not only reduces the temperature but also saves electricity. From a health point of view, the best temperature difference between indoor and outdoor in midsummer is 4-5 degrees centigrade, which can prevent cold due to excessive temperature difference between indoor and outdoor, otherwise it is easy to get "air-conditioning disease".
2. Frequent switch on and off will damage the machine and power consumption: when the air conditioner is turned on and off when it is hot and cool, the air conditioner will always be in operation. After all, when the air conditioner is turned on, it will be in the most dynamic state, and the power consumption will also go up slowly. Experts remind that if you leave the room for a long time, you should turn off the air conditioner. The power consumption of the air conditioner is large when the air conditioner is turned on. You should avoid frequent switching on and off. The air filter screen should be cleaned at least once a year.
3. Frequency conversion air conditioning is more energy-saving: choose frequency conversion air-conditioner with high environmental protection and energy efficiency, and the energy consumption ratio increases by 0.1, which can save electricity by 4%. The variable frequency air conditioner can adjust the temperature faster than the constant speed air conditioner. After reaching the set temperature, the frequency conversion air conditioner can operate at a low speed with only 10% of the power of the fixed frequency air conditioner, so as to adjust the slight loss of temperature and maintain the constant temperature.
4. It is cooler to use with fan: the combination of electric fan and air conditioner can not only improve the refrigeration efficiency of the air conditioner when it is started, but also appropriately raise the air conditioning temperature, which can increase the widely accepted room temperature from 26 ℃ to 28 ℃, which saves electricity and money.
3. Electric fan
1. Use the middle or slow gear: the power consumption of the electric fan is directly proportional to the speed of the fan blade. When the air volume meets the requirements, use the medium or slow gear as far as possible. For example, a 400mm fan consumes 60 watts of power when it is in fast gear and only 40 watts when it is in slow gear, which can save one third of power.
2. Fast gear first and then gear adjustment: if the electric fan starts from the slow gear at the beginning of starting, the slow gear voltage is low, the starting speed is slow, and the current is 4-8 times larger than normal, which consumes more power and also affects the service life of the fan. In normal use, the faster the speed of the electric fan, the greater the power consumption. For the same electric fan, the power consumption difference between the fastest gear and the slowest gear is about 40%. Therefore, the electric fan can use high speed gear in the start-up stage, and then change to medium speed or low speed gear after reaching the rated speed.
3. Regular maintenance: in addition, well maintained electric fans can save electricity; fans that are short of oil, have variant blades and are easy to vibrate consume electricity. Cleaning the electric fan timely can keep it clean and save energy.
4. Audio visual appliances
1. Adjust the brightness to save energy: don't turn on the brightness too much when using the TV set, which can not only save energy, but also prolong the service life. Each additional 1 Watt Audio strategy increases 3-4 watts of power, and the brightest state consumes 50-60% more power than the darkest state. If the TV brightness is lowered, it can save 10% in general.
2. Dust proof effect: add a dust cover, can prevent the TV inhale too much dust, dust, TV easy leakage, increase power consumption, but also affect the quality of sound and image.
5. Refrigerator
The refrigerator is almost non-stop all year round. Except for power failure or ice shoveling, the refrigerator of Xiaobian family will not stop working at other times. So, it's not sure that it will consume a lot of electricity when it's on all day. If you do the following steps correctly, you can save more electricity!
1. Avoid increasing the temperature around the refrigerator: most families choose to put the refrigerator in the kitchen, but in fact the kitchen temperature is too high, it is not suitable to put the refrigerator. If it can not be changed, it should be placed in the back shade to avoid direct sunlight. At the same time, do not put it together with the oven, TV, stereo, microwave oven, etc., which will increase the power consumption of the refrigerator.
2. Food storage should not be too full: the food should be stored in convection space to keep the temperature in the box balanced; hot food should be cold to room temperature before putting into the refrigerator, hot food will lead to the refrigerator to increase the refrigeration strength, resulting in increased power consumption.
3. Adjust the refrigerator temperature properly: the external conditions also have an impact on the work of the refrigerator. The refrigerator temperature controller should be adjusted reasonably according to the seasonal changes, food types and quantity. According to the characteristics of the refrigerator, after all, the refrigerator has a temper!
6. Others
1. The washed rice is soaked in the pot for 30 minutes and then boiled in warm or hot water, which can save 30% of electricity.
2. Cut off the power when the appliance is not in use. Although the energy consumption of household appliances is less, it also accounts for about 10% of the total household electricity consumption. If you add up a little, you still need to develop the habit of turning off the power supply.
3. The water heater can be set with timing switch on and off. It is not necessary to turn on the water heater all day long. It is a good way to save energy when it is turned on at noon or at the hottest time in the afternoon. It can be turned off automatically at midnight and early in the morning.
After watching so many power-saving tricks, do you feel like suddenly rising posture? Get up immediately, you can also be a housekeeper.
