While home appliances have brought convenience to our lives, we have also created many annoyances, such as high monthly electricity bills. People like Xiao Bian are not few in the summer because they are afraid of excessive electricity bills and are afraid to over-open air conditioners. In fact, in addition to the normal power consumption when household appliances must be used, the waste of electrical energy due to poor usage habits cannot be overlooked.
Home Appliances Truth Lab: Set-top box steals 10 degrees a month?
Recently, a news about the TV set-top box waiting for a month to "steal" 10 watts of electricity really shocked people. Who would have thought that the humble TV set-top box was actually a big consumer. Today, we talked to you about the energy consumption problem of household appliances standby. By the way, we helped you figure out how much money you spent in the home appliance standby mode in the year.
STB standby one month "stole" 10 degrees?
Before we begin, we must first understand a problem:
Why not use electrical appliances?
As long as the appliance is in a powered-on state and the circuit board, display, and necessary program settings are on standby, there is bound to be power loss. There are about 20 types of household appliances in ordinary households. Although the standby power is very low, if the standby power is continued for 365 days a year, the standby energy consumption of all household appliances is added together. This is not a small expense.
If divided according to usage habits, home appliances can be divided into the following three categories:
The first type: 24 hours open type;
Such as refrigerators, drinking fountains, routers, etc.;
The second category: ready-to-use;
Such as televisions, air conditioners, range hoods, microwave ovens, air purifiers, set-top boxes, etc.;
The third category: plug and play type;
Such as hair dryers, vacuum cleaners, electric irons, etc.
It is not difficult to see that in the average family, the most common type of appliance is the second type. The plug is always connected to the terminal board and is ready for use immediately. Due to the usage habits of home appliances, the placement of electrical appliances, and the circuit design, these out-of-the-box appliances are as if they are attached to the sewers on the entire home circuit. They keep the meter running at a constant pace every day.
Large appliances: main source of standby power
Ice washing and other large appliances are usually large household appliances, refrigerators, air-conditioning compressors, washing machines, hoods, the motor running power, but the standby power is basically maintained at a level of reassuring.
42" LCD TV
Standby power 0.49W; running instantaneous power 59.45W
Big 1 fixed frequency air conditioner
Standby power 1.83W; cooling operation instantaneous power 930.99W
350 litre double door refrigerator
Running instantaneous power 68.82W
Other large appliances:
Drum washing machine: standby power 0.69W.
Continental range hood: standby power 1.54W; running instantaneous power 125.22W.
Since everybody has a fixed position and a fixed position at the time of level, it is not likely to be frequently plugged and unplugged in the usage habits, which has become a main source of standby power consumption.
Small appliances: routers do not need electricity for long
With the improvement of living standards, there are also many small household appliances in ordinary households. How about standby power consumption of small household appliances?
table lamp
Standby power 0W; operating instantaneous power 6.90W
Floor fans
Standby power 1.57W; running instantaneous power 43.95W
air purifier
Standby power 0.48W; running instantaneous power 48.83W
Water dispenser
Heating instantaneous power 351.46W
mobile phone charger
Standby power 0; instantaneous power 6.73W
router
Router 1 power 3.91W; Router 2 power 1.99W.
other:
Laptop: Standby power 0.72W; running instantaneous power 22.76W.
The overall power of a small home appliance is generally kept below 1 W in the standby state. It is worth mentioning that the instantaneous power of the two routers we tested was 3.91W and 1.99W, respectively, and the online rumor that the router “stolen†power was not established. In addition, the power of the mobile phone charger in the uncharged state is 0, and many people do not like to pull the charger after charging, which has no effect from the perspective of electricity expense.
Set-top box "stolen" 10 degrees a month?
Finally, let's look at how much standby power the digital set-top box is. As shown in the figure, the power of the digital set-top box in the off state is 0, but when the set-top box is started, the instantaneous power reaches 17.25W. At this time, we can see that the set-top box shows time, the TV is not turned on at this time, and the set-top box is not Generates data transmission with the TV. When we turn on the TV, the power of the set-top box is 17.61W when the set-top box and the TV generate data transmission.
Set-top box standby power 0W
No data transmission power 17.25W after power on
17.71W power when viewing digital TV after power on
Strictly speaking, the standby power is the power of the appliance when the power is turned on and not turned on. Therefore, the set-top box does not consume electricity in the standby state. However, according to the placement of the set-top box and the use of habits, many people have not noticed this detail, as long as the set-top box in the open state regardless of watching TV, the meter will be flying at a rate of 12 degrees per month, plus The standby energy consumption of other electrical appliances, a year later, more than 200 kWh is gone.
Household appliances waste 267 kWh of electricity a year
From this, it seems that the rumors of online "stolen" 10 kWh of power for a set-top box on the Internet for a month are true, but it is only that the statement is not very rigorous. Set-top box standby does not need electricity at all. If you forget to switch off the back of the top box, it is still possible to “stealing†more than ten degrees of electricity a month.
The use of air conditioners in summer has become more frequent, and friends who feel bad about their electricity bills are eager to stare at the electric meters while they are air-conditioned. The electrical appliances necessary for life must be used. As long as we change some bad electricity habits, how can we use air-conditioning to save more hours of air-conditioning?
