Save electricity daily.

Low-carbon environmental protection has long been a social development trend, which is actually our reflection and action on the waste caused by the unilateral pursuit of development and comfortable life in the past. As far as electricity is concerned, it is difficult to accurately count how much waste there is. However, Shenzhen Power Supply Bureau has done a calculation. As far as Shenzhen is concerned, if everyone saves 1 kWh every day, Shenzhen can save more than 5 billion kWh a year, which is enough for Wenchuan to use for 50 years.

How to save 1 kwh? Here are a few simple examples: unplugging spare electrical appliances, such as TV (345 watts) and stereo (200 watts), you can save 1 kWh in about two days! Buy non-ironing clothes and reduce the use of steam iron (1500 watts) for 40 minutes, which can save 1 kwh! Power consumption system side: System power saving technology includes surge, transient suppression technology, harmonic elimination technology, reactive power compensation technology and system impedance balance technology.

Lighting load side: fixed-point adjustment, high impedance state reactance technology and chopping technology.

Power load side: soft start technology, frequency conversion technology, system power saving technology.

Don't exceed the limit in summer.

It's unbearable hot in summer, and the air conditioning fans are all on. Fire and electric shock accidents caused by the use of these electrical appliances occur every year. How to make science of electricity safe is an important matter that every family must pay attention to.

First of all, the bearing capacity of watt-hour meter and low-voltage line should be considered. The electric power that a watt-hour meter can withstand is similar to the value of voltage multiplied by current. The voltage of domestic electricity is 220 volts. For example, if a 2.5-amp watt-hour meter is installed at home, the power it can withstand is 550 watts, and a 600-watt rice cooker cannot be used. In this way, the electric power that a 5-amp watt-hour meter can bear is 1 100 watt.

Secondly, it should be considered that a socket allows several appliances to be plugged in. If the sum of the maximum power of all electrical appliances does not exceed the power of the socket, there is generally no problem. When using sockets with more than three pairs of jacks and using high-power appliances such as air conditioners, electric cookers, rice cookers and electric water heaters at the same time, the sum of the powers of these appliances should be calculated first. If the limited power of the socket is exceeded, the socket will burn out due to excessive current. At this time, the number of electrical appliances used at the same time should be reduced to keep the total power within the allowable range of the socket.

In addition, the installed circuit breaker must use the corresponding standard fuse. Do not use other metal wires instead, otherwise it will easily cause fire and damage electrical appliances. In case of fire caused by household appliances, you must first cut off the power supply and then put out the fire to avoid electric shock and injury. No matter what type of refrigerator, it should be placed in a cool and ventilated place, and there should be a gap between the back and the wall, which saves about 20% energy every day compared with sticking it on the wall.

2. The refrigerator should be opened less and quickly. In addition, the temperature adjustment file in the refrigerator should be moderate, and it is not suitable to place strong cold, so as not to increase the workload and power consumption of the refrigeration cycle system in the refrigerator.

3. The general food has the best preservation effect at 8 ~ 10℃. The stored food should not be too full, and there should be a gap of more than 10 mm between the food and the box to facilitate the convection of cold air in the box.

4. When storing hot food, put it in the refrigerator after cooling, and store it in small pieces to avoid repeated freezing. Chicken, fish, etc. Take out the internal organs, refrigerate first, and then freeze, thus reducing power consumption.

In general, when the frost layer on the evaporator surface in the refrigerator reaches more than 5 mm, it should be defrosted. If the frost is too thick, it will produce great thermal resistance and increase power consumption. Always keep the back of the refrigerator clean, because the dust on the surface of the condenser and compressor will affect the heat dissipation effect.

In summer, there is usually nothing in the freezer of the refrigerator. At this time, several containers such as plastic boxes or microwave oven boxes can be filled with water and put into the freezer. After the water turns into ice cubes, the ice cubes will be transferred to the freezer and placed under or beside the thermostat, so that when the cold air is emitted upwards, the temperature around the thermostat will be reduced, thus reducing the number of times the thermostat is started and achieving the purpose of saving electricity. At the same time, when the ice melts, it will absorb a lot of heat, which will also play a role in cooling and keeping fresh the food stored in the refrigerator. 1, the power of the air conditioner should match the building area, generally calculated at 200 kcal per square meter, and the air conditioner should be installed on the upper part of the window facing the sun.

2. When using air conditioner, the temperature should not be too low. The state suggests that the temperature of household air conditioner should be set at 26-27 degrees in summer. Every time the air conditioner is raised 1 kwh, the power load can be reduced by 7% to 10%.

3. The air conditioner can't start the compressor frequently, and it can only be started after stopping for 2 to 3 minutes, otherwise it will easily cause the compressor to be overloaded and burned, consuming a lot of electricity.

4, air conditioning in summer, if it is wall-mounted, air conditioning should be put high, which is conducive to air convection and let the indoor temperature drop as soon as possible.

5. Change the air in the room in advance when using the air conditioner. If you need to open a window, the gap between the windows should not exceed two centimeters. In the process of using air conditioning, we should control the opening of doors and windows as much as possible. If the inverter air conditioner is used, when the indoor temperature is always the same as the outdoor temperature, then the inverter air conditioner will increase the frequency, overload work and increase consumption. If you want to stop and get some air, you'd better turn off the air conditioner 20 minutes before opening the window.

6. Choose an appropriate air outlet angle: the air outlet should be upward when cooling and downward when heating.

7. Cooperate with electric fan and sunshade. The blowing force of the electric fan will accelerate the circulation of indoor cold air, and the cold air will be evenly distributed, thus achieving better cold air effect. Using curtains and other shading methods to reduce the influence of sunlight radiation on room temperature can also save electricity for air conditioning and refrigeration.

8. Using the sleep function can save 20% electricity.

9. Don't wear a "raincoat" for the external machine, because it will affect heat dissipation and increase power consumption.

10, the filter screen on the air conditioning panel should be cleaned once every half a month or so. If there is too much dust, it should be cleaned in warm water not exceeding 45℃, dried and pressurized.

1 1. In summer, the temperature of the air conditioner should be kept between 35-37℃. Unplug the TV when it's not watching, and don't put it on standby.

2. Make the color, volume and brightness level of the TV feel the best, which can save 50% electricity and prolong the service life of the TV. In addition, when turning on the TV, the volume should not be too high. Because every 1 watt of audio power will increase the electrical power consumption by 3-4 watts. High brightness also consumes power.

Lighting:

1, lighting should make full use of reflection and reflection, for example, a suitable reflector can improve the illumination.

2. Using energy-saving lamps is also a good way to save electricity.

3. Try to reduce the number of lights turned on and off. Every time it is switched on and off, the service life of the lamp will be reduced by about 3 hours.

4. Keep the bulbs and lampshades clean, and improve the luminous and reflective effects. After the lamp is used for a period of time, the luminous flux will drop greatly and the lamp will get darker and darker. At this time, attention should be paid to replacing the new lamp in time. 1, do not use the computer for a short time, and start the computer "standby" mode.

2. Be sure to unplug the power after the computer is turned off.

3, the choice of monitor should be appropriate, because the bigger the monitor, the more energy consumption.

4. Turn off the monitor while listening. 1, household electric irons usually have temperature regulation type and ordinary type. The former is more conducive to saving electricity. It is also best to choose an ordinary electric iron with a switch on the handle, which can control the temperature at any time and reduce power consumption.

2. The electrifying time of the electric iron should be mastered at any time according to the temperature required by different materials.

Making full use of the waste heat of electric iron is also a way to save electricity. For example, when ironing the front of woolen clothes, a higher temperature is needed, and when ironing the back, a lower temperature is needed. 1. Before cooking with a rice cooker, it is best to soak the rice for about 30 minutes and cook with warm water or hot water, which can save electricity by 30%. When cooking, cover the rice cooker with a towel to reduce heat loss.

2. The electric heating plate is the main heating part of the rice cooker. Keeping the electric heating plate clean can improve efficiency and save electricity. Wipe with a clean soft cloth after each use, and the burnt film can be scraped off with sawdust and plastic cloth. 1, the power consumption of the washing machine depends on the service time. The washing time depends on the type of clothes and the degree of dirt. Synthetic fibers and wool fabrics are generally washed for 3 to 4 minutes; Cotton and linen fabric for 6 to 8 minutes; Extremely dirty clothes 10 to 12 minutes.

2. In the same long washing cycle, the blades of "weak washing" rotate more times than those of "strong washing", and the motor will be started repeatedly. The starting current of the motor is 5-7 times of the rated current, so "weak washing" consumes electricity instead; "Forced flushing" can also extend the life of motor.

3. Dehydrate for 2 minutes after washing. Clothing dehydration 1, 680 rpm 1 min, the dehydration rate can reach 55%, and the dehydration rate is rarely improved by prolonging the time.

4. soak first and then wash. Before washing, soak the clothes in liquid soap or washing powder solution for 10- 14 minutes, let the detergent react with the dirt on the clothes, and then wash. In this way, the running time of the washing machine can be shortened by about half, and the power consumption can be reduced by half accordingly.

5. Rated capacity. If the amount of washing is too small, it will waste electricity; On the contrary, washing too much at a time will not only increase the washing time, but also cause the motor to overload, which not only increases the power consumption, but also easily damages the motor.

6. Water consumption is moderate. Too much water will increase the water pressure of wave plate, increase the burden of motor and increase power consumption; Too little water will affect the clothes turning up and down during washing, increase washing time and increase power consumption. How to save electricity with electrical appliances 1 Gas water heaters are more energy efficient than electric water heaters.

The ideal capacity of water heater is 20~50 liters.

Please turn off the water heater switch when not in use.

4. Install a low-flow shower nozzle and use shower instead of bath.

There are many solar water heaters available in the market. For example, vacuum tube solar water heaters, which are common in bungalows, are suitable for bungalows or villas with their own courtyards. Ordinary people living in buildings can purchase wall-mounted solar water heaters after consultation with property companies. According to the case calculation, using solar water heater can save about 100 kWh per month. 1, according to the amount of food, use a pot of appropriate size to cook.

2. Make sure that the size of the pot matches the size of the stove.

3. The iron pot transfers heat faster than other ordinary pots.

Covering with cooking food can make more efficient use of energy.

Pressure cooker and microwave oven can shorten cooking time and save energy.

6, check the furnace burning flame, blue flame is normal. The yellow flame indicates that the gas combustion is insufficient and may need to be adjusted to improve energy efficiency and achieve the purpose of energy saving.

7. Among all kinds of food cooking methods, steaming and boiling are the most energy-saving cooking methods. At the same time, it also reduces the generation of lampblack and saves the unnecessary power consumption of the range hood.
