At the end of the year and the beginning of the year, there is often a surge in household electricity consumption, which is followed by a skyrocketing electricity bill.
I don't know if you have ever encountered the "electricity bill assassin"?
In fact, high electricity bills are closely related to the bad electricity habits we develop in our daily lives, but this has not attracted people's attention.
Data show that at present, the annual electricity consumption of household appliances in China due to standby state is about 200 billion kWh, which is equivalent to the annual power generation of the Three Gorges Hydropower Station.
It's easy for people to neglect to unplug when turning off household appliances, and this habit can add an unnecessary expense to your monthly electricity bill.
If you don't pull out the plug after using the following four appliances for a long time, then the annual household electricity bill may cost hundreds or even thousands of yuan more.
At present, the output power of domestic TV set-top boxes is generally 15 20W, and the output power during standby is about 5W.
It seems that the set-top box does not consume much power when it is in standby, but when the TV is in standby,TV set-top boxes still function as signal converters.
In other words, until we completely cut off the power of the TV and the set-top box, the set-top box will always be working by default, but the TV screen will not display the picture.
Nowadays, people tend to use the remote control by default when turning off the TV, so it is easy to neglect to turn off the power of the set-top boxIf the set-top box is in working condition for a long time, it will cause a waste of electricity.
Generally, after using the remote control to turn off the TV, if the user does not cut off the power of the TV or unplug the power plug, then the TV will enter standby mode.
The power on indicator of some TVs will still be highlighted.
The data shows that the output power of the current domestic mainstream size TV is generally 100 200W, and the output power of a few large-size TVs can reach about 300W.
The average power consumption of a TV in a standby day is about 0Around 5 degrees,If you include the power consumption of the set-top box, it will consume nearly 20 kilowatt-hours more electricity per month on average.
Although the TV boot rate of domestic families is not high, sometimes it is often ignored once and a lot of unnecessary costs will be generated.
If you don't often turn on the TV at home, then it is recommended that you directly unplug the power plug and completely isolate the power supply.
After all, you can save 100% of your electricity bill without using electricity, and friends who use TVs frequently can reduce unnecessary power consumption by turning off the standby mode.
The energy consumption of a TV is closely related to the material and size of the screenIt is recommended that friends who have high requirements for the eye protection and energy consumption function of the TV choose LCD screen instead of OLED screen
Compared with TVs with a low boot rate, people are generally very concerned about the power consumption performance of air conditioners, after all, air conditioners are used frequently and for a long time, especially in summer and winter, they are the "main output" in family electricity bills.
At present, domestic air conditioners are under the summer refrigeration standard, 1A 5 hp air conditioner consumes about 1 percent of electricity per hour2～1.5 degrees.
The average hourly power consumption of a 2 hp air conditioner can reach 2About 5 degrees, calculated according to the current domestic tiered electricity price,At the end of each year, there may be many families who will encounter "electricity bill assassins".
Nowadays, air conditioners have become a must-have in home life, and people often do not unplug the power supply of air conditioners in order to avoid trouble.
As everyone knows, this not only wastes electricity, but also reduces the service life of the air conditioner.
After using the remote control to turn off the air conditioner, if the power is not cut off in time, the air conditioner will enter the standby state by default.
Generally, the power of the air conditioner in standby is between a few watts and more than ten watts, and the power consumption of the air conditioner will be higher and longer as the standby time of the air conditioner becomes longer.
If the power supply of the air conditioner is not cut off for a long time, it is easy to accelerate the aging of the line, which in turn induces generator failure or even fire.
Generally speaking, the air conditioner consumes the most power when it is first started, and when the indoor temperature reaches equilibrium, it will enter a stable operation state and the energy consumption is not high.
Therefore, it is not recommended that you turn the air conditioner on and off frequently, and try to unplug the power plug when not in use.
In fact, there are many tricks for air conditioning electricity, such as adjusting the air outlet angle, setting the air conditioning temperature reasonably, and so on.
However, the best way to regulate the air conditioning is to clean the filter regularly.
This not only improves the efficiency of the air supply but also reduces power consumption, while also ensuring that the air is fresh and prevents dust from blowing into the room.
Moderate use of air conditioning can play a role in regulating the indoor temperatureHowever, we must not expose ourselves to the air conditioner for a long time, especially if it blows directly on the air conditioner.
With the continuous innovation of modern technology, the mainstream air conditioners on the market are generally equipped with a timer mode or a sleep aid mode.
We can use technology to better play the role of air conditioning, and at the same time, we can also achieve the maximum power saving experience.
In the distribution of electrical appliances in the family, the kitchen is definitely the core area where all the "good hands" gather together, and all kinds of household appliances such as refrigerators, range hoods, and induction cookers are dazzling.
However, compared to the relatively intuitive high power consumption of large electrical appliancesSome seemingly inconspicuous small appliances in the kitchen are likely to become hidden "electricity bill assassins" because of your electricity habitsSuch as microwave ovens, rice cookers, and so on.
Generally speaking, the power range of a microwave oven or rice cooker in standby mode is 1 3W.
However, as the standby time increases, the corresponding standby power consumption will continue to rise, but people are often reluctant to unplug the power supply for fear of trouble.
The mainstream microwave ovens on the market today generally have a variety of practical functions.
For example, when you turn the knob to a different function, it means that the standby power of the microwave will change accordingly, which will consume more power.
The rice cooker does not automatically cut off the power supply after completing the specified task, but automatically enters the keep warm mode when the power is connected, which also consumes a certain amount of power.
Although the output power of small kitchen appliances is not high,However, it is also unable to withstand the long-lasting power consumption generated by long-term standby mode.
If you do not unplug the power plug for a long time, it will slowly increase the power consumption and will also affect its service life.
In terms of power-saving strategies for small kitchen appliances, in addition to directly unplugging and saving 100%, we can also make reasonable use of waste heat from heating equipment or take the initiative to purchase advanced energy efficiency equipment.
At present, the energy efficiency level of domestic rice cookers is generally in the second level or **, while the microwave oven has many first-class energy efficiency products to choose from.
However, it is important to remember that small kitchen appliances do not have more power to save more power.
In fact, in the process of using kitchen appliances, we can reasonably choose the corresponding appliances according to the goals we need to achieve.
For example, we can use a rice cooker to cook dishes at regular intervals, or use an induction cooker to make baked goods, etc.
Among the many household appliances, electric water heaters have always been quite controversial.
According to the way of the debate, the positive point of view is that there is no need to pull the power plug of the electric water heater, and the reason is that it can take a bath at any time without time limit.
Second, the constant temperature mode designed by the manufacturer can try to avoid the loss caused by long-term plug-in to the equipment.
The opposing argument is that the plug of the electric water heater should be unplugged when it is clearly not in use, because this can not only save electricity but also effectively extend the service life of the equipment.
An electric water heater that is powered on for a long time will naturally produce a certain amount of electrical energy consumption.
However, between convenience and power consumption, many people prefer not to pull the plugIt's just that people tend to ignore the safety problems caused by the long-term power supply of electric water heaters.
At present, the power range of mainstream electric water heaters in China is 2 6 kilowatts.
Taking a 2 kilowatt electric water heater as an example, the power consumption in the all-day heat preservation state is about 2 kWh, so that the monthly power consumption can reach 60 kWh.
However, for the electric water heater that is in standby mode all day, its daily power consumption can basically be controlled at 0Within 5 degrees.
The electric water heater seems to consume little electricity throughout the day, but in fact, it is also a large expense if it is accumulated for a long time.
At present, China's electricity tariff pricing model is gradually transitioning from a tiered electricity price to a peak-to-valley electricity price model.
For households that have not unplugged the electric water heater for a long time, they may pay more electricity bills in the future because of this habit.
The heating power and standby power of an electric water heater are related to the intrinsic energy consumption coefficient and hot water output rate determined by its energy efficiency level.
It is recommended that you try to choose first-class energy efficiency products when purchasing electric water heaters.
At the same time, according to the life rules of family members, gradually develop the method of staggered heating to control the water temperature of the water heater, instead of letting it be kept warm or standby for 24 hours.
Of course, regular cleaning of the water tank and heating rod in the water heater can also play a role in efficient heating and reducing energy consumption.
In the modern society with the rapid popularization of smart home, we can get rid of the limitations of time and place with the help of intelligent operation methods.
Energy consumption is reduced by remotely controlling the heating time and temperature of the electric water heater.
With the gradual popularization of green and low-carbon lifestyles, people's attention to the energy consumption of household appliances is also increasing.
In fact, the electricity bill should not be a confused account in the first placeWe are fully capable of saying no to the "electricity bill assassin" and can reasonably plan the electricity consumption pattern of the home.
Compared with paying close attention to the energy consumption level of major appliances, some inadvertent electricity consumption habits often become the "electricity bill assassins" hidden around us.
For example, the always-on set-top box, the standby state of the air conditioner, and the "killer" of various kitchen appliances, etc.
In addition to choosing electrical products with high energy efficiency levels at the beginning, we should also use electrical appliances reasonably and develop good electricity habits in accordance with the design specifications of the manual.
It is not terrible to have encountered an "electricity bill assassin", but it is terrible to choose to compromise with the so-called "convenience" when you know that you can improve the electricity consumption pattern.
