Will it consume electricity if I do not unplug the smart switch socket when I go out? See how much power your appliances consume! After the outbreak of new coronary pneumonia, saving resources has once again become a topic of our concern. In people's daily life, many details of electricity use are often overlooked by us. When the charger is not charging, will you continue to connect to the power supply or unplug it? Will the meter go if the plug is not unplugged after the electrical appliances at home are turned off? Suppose my home appliances are turned off, but the plug is not unplugged, will electricity bills be incurred? Can! Since you just turned off the power of the electrical appliances and did not unplug the power plug, the power supply of these appliances is still working. This situation is also called the standby situation. Although the power consumption is not much, it accumulates power consumption for a long time. It's not too small! Knowledge point, most home appliances do not directly use 220 volts to communicate with the mains. They need to step down, stabilize, and rectify. Therefore, whether you use traditional coil transformers or power supply ICs, there will be quiescent currents. These quiescent currents are not only Consuming electric energy, it will continue to generate heat. In a previous query, more than half of the interviewees said that for convenience, the charger has been connected to the power source. Assuming that hundreds of millions of families do not pay attention to these, the conclusion is quite amazing. Which appliances consume power when in standby? How big is the power consumption?
1. Central air conditioner, large area of residence, the energy consumption of central air conditioner in standby is also relatively large, a central air conditioner consumes about 2 kilowatts of electricity a day in standby, which is 60 degrees in a month.
2. The television, after the television is turned off, the picture tube is still in the filament preheating state. In the standby state, the power consumption of the television is about 0.5 degrees a day, which is 15 degrees a month.
3. General air conditioners, assuming that they do not unplug the socket after turning off the power, the standby power is about 12.5 watts, and it consumes about 9 degrees a month.
4. The power of the computer and wireless router in standby mode is about 5 watts, which consumes 3.6 kWh per month.
5. Drum washing machine, the standby power of drum washing machine is about 0.7 watts, which is very small among household appliances, and consumes about 0.5 kWh a month.
6. Stand-by power and working power of set-top boxes and TV set-top boxes are basically the same, and the power consumption per day is nearly 0.4 degrees. Assuming that the set-top box is in standby and working conditions for a year, it will consume more electricity from Baidu. Of course, in addition to power consumption, leaving the set-top box on for a long time can simply cause a fire.
7. Electric water heaters, the standby power of electric water heaters is not large, as long as about 3 watts, assuming that the standby power consumption is about 2 degrees a month. The difference is that in order to maintain the water temperature, the electric water heater will operate separately when the temperature difference is too large. Each brand of electric water heater consumes different power. Generally speaking, a 30-40 liter electric water heater has a power of about 2-2.5 kilowatts, and it is 2 kilowatts of electricity for one hour of operation. The greater the indoor temperature difference, the longer the operation time, the more power consumption, and vice versa.
