On the 19th is the “World Measurement Dayâ€. On the 18th, the State Grid Beijing Electric Power Company launched a half-month “Social Responsibility Promotion Month†event, which was incorporated into households to “diagnose†households to analyze household electricity consumption. The household survey found that the small set-top box turned out to be the biggest “thief stealingâ€â€”even if it was not in the standby state for watching TV, it lost about 10 kWh a month.
Yesterday morning, the reporter followed the staff of the electric power department to Ms. Liu’s home in Beiyuan, Haidian District to test the standby and operating power of high-power household appliances such as TVs, refrigerators, water heaters, and air conditioners.
The electric power worker first detected the smart meter and showed that everything was normal, and then he detected the high-power appliances one by one.
Calculation results show that, in the standby state, Ms. Liu's air-conditioning at home consumes about 1.45 degrees per month, the TV is about 0.16 degrees, and the router is about 1 degree. Surprisingly, the small set-top box next to the TV had to “eat†10 kWh a month.
This figure stunned Ms. Liu. She said that she did not expect the set-top box to consume so much power. At present, the time spent watching TV at home is relatively small. Usually, it will shut off the television but will not shut down the top box. "It must be turned off when you don't watch it later," said Ms. Liu.
According to electric power workers, the general public will not notice that the set-top box will consume so much electricity. It is recommended that the public switch off the set-top box when not in use.
During the “Social Responsibility Promotion Month†campaign, Beijing Electric Power selected two households to diagnose the power consumption of household electricity. From now on, citizens will be collected from time to time for measurement to guide citizens in using electricity scientifically and saving electricity. Citizens can pay attention to the company's public number and keep abreast of free surveying activities. If the public feels that the power of household appliances in the home is abnormal, they can also call 95598 to apply for a free verification of the smart meter. The power company staff will come to the site within five working days.

At the scene yesterday, the electric power personnel also conducted field tests on other electric appliances and introduced energy saving tips for children in their lives. The newspaper checked the contents of related tests and provided a wake-up call for the public. Various electric appliances in the future will be more useful. Use more energy.
Power consumption ranking electric appliance power saving tips
First place
Water heater
This is a big consumer of electricity and "local tyrants" in household appliances. Its operating power is 896B3000 watts, and it consumes 0.896B3 degrees in one hour. If it is always on, it will run heating repeatedly to ensure the water temperature. The power consumption is quite considerable. In the insulation state, the power is about 1000 watts, and 1 kWh will be eaten in 1 hour.
Please remember to open the water heater properly before use. It is best not to keep it warm for a long time.
Second place
air conditioning
The operating power of the air conditioner is 600B2860 watts, which consumes 0.6B2.8 kWh in one hour. Standby power 1B 5.25 watts, the standby power of the highest air conditioning in standby mode consumes electricity once in 8 days. In addition, there is no correlation between the size of the standby power and the operating power.
The air conditioner is completely off during the off-season air conditioning. When using air conditioners in summer, do not set the temperature too low. After running for a period of time, set it to 27 degrees. Variable frequency air conditioners can be used to save power, save money, and reduce noise. In addition, air-conditioning filters must be cleaned in a timely manner.
Third place
TV
In the past two years, since the launch of various reality television shows, the appeal of television has further increased. TV operating power 50B190 watts, 1 hour power consumption 0.05B0.19 degrees. Standby power 0.7B8.8 watts, consumes electricity once every 5 days. As long as you remember when you turn off the TV and unplug the power at the same time, its power consumption still has the conscience of the industry. The supporting role of the TV - the set-top box is not unknown, as soon as possible to turn off.
It is highly recommended that you turn off the power with the remote control before disconnecting the power supply to prevent loss of power.
fourth place
refrigerator
Body size and power consumption are not proportional, it is a "box" and is a friend who can make friends. Its standby thermal power is very small, the power after cooling is relatively large is 65B100 watts, and the power consumption is 0.065B0.1 degree per hour. The refrigerator is normally on for 24 hours, but the refrigeration compressor does not continue to operate. It does not consume electricity and can be used with confidence.
It is recommended to use the national standard energy-saving refrigerator and place it away from the heat source. Do not open the refrigerator door for a long time and do not stack the items too full or too dense. In addition, the defrosting should be carried out in a timely manner. The frost layer in the freezer compartment can reach 4B6 mm. When cooling, it will consume 1/3 more electricity than normal cooling.
The handheld addresser is used to program the address of the monitoring module offline. When in use, connect the two output wires of the handheld encoder to the communication bus terminal (terminal label 1, 2) of the monitoring module, turn on the black power switch on the right side upwards, and press "ten Add", [Subtract ten", [Add one place" and [Subtract one place" to program the address.
