How much is the electricity on the air conditioner per month? What's the secret of saving? | my navigation news
How much is the air conditioning charge?
I began to feel hot in summer and had to use the air conditioner. Especially in the recent summer, the heat continues. In the sense of preventing heatstroke, it is also recommended not to use air conditioning reluctantly. So, how long does it take on average to use air conditioners in summer?
According to the Household Expenditure Survey (Household income and Expenditure) per Household monthly Expenditure (more than two households) by the Bureau of Statistics of the Ministry of General Affairs, the electricity charges from June to October 2020 are as follows:
June 9153 yen July 8585 yen August 9661 yen September 11206 yen October 10152 yen
After the end of the Meiyu, the electricity bill began to rise sharply after the temperature rose in August. In September, the electricity bill peaked at more than 10,000 yen. In October, as the temperature dropped, the electricity bill fell by more than 1000 yen, but still sat on the big off. By the way, the electricity bill in November and December is 8965 yen and 9137 yen respectively. After that, if it is cold, the electricity bill will go up this time because of the use of heating equipment.
According to the Ministry of economy, Trade and Industry, air conditioners account for 58 per cent of household electricity at around 14:00 during the daytime in summer. When it is hot, the electricity bill will rise, but the air conditioner still seems to have a great impact on the electricity bill.
From "Summer Power Saving menu (everyone in the Family)" in May, 2007.
According to the electricity cost of the air conditioner, you can also calculate it yourself. Here, I will introduce how to calculate the electricity bill per hour and one month. To calculate the electricity bill per hour
"Power consumption per hour (KW) x usage time (hours) x unit cost (yen / kWh)"
You can ask for it.
The power consumption is recorded in the fuselage and operating instructions of the air conditioner. Let's confirm it. In addition, power consumption is different in cooling and heating. In the actual calculation, the power consumption is set to kW (1000W=1kW). For example, if the description is 800W, it is 0.8kW.
The price per kilowatt depends on the contracted power company and its plans. Let's confirm it by reading the meter. For example, if you use an 800W air conditioner for an hour and the unit price is 26 yuan / kWh, the electricity charge is 0.8kW × 26 yen / kWh=20.8 yen.
Next, let's calculate the electricity bill for each month. The monthly electricity bill
"electricity charge per hour x use time of a day x days of use of a month"
You can forget it. Based on the electricity charge of 20.8 yen per hour, 8 hours per day and 25 days per month, it is calculated that 20.8 yen x 8 hours × 25 days = 4160 yen. However, the power consumption of the air conditioner will change during operation, so it is not necessarily the exact amount. Get a general idea of how much air conditioning costs in summer.
Save the cost of air conditioning
To some extent, it is impossible for the electricity bill to become higher in the hot summer. But, if I can, I'll find a way to control it. What should be done to save the cost of air conditioning?
Although you are very concerned about the electricity bill, you should also avoid the diligent switch of "turn off the switch when it gets cold and turn it on when it gets hot". On the contrary, it will become the reason for the increase in electricity charges.
This is because the air conditioner has the highest electricity bill before lowering the room temperature to the set temperature. In other words, if the switch is turned off because of the cool weather, the next time the air conditioner is turned on again, it will cost extra electricity. For the same reason, it's not good to drive weakly from the start. Because it takes a long time to reach the set temperature, the electricity bill will increase accordingly.
If you want to save on the electricity bill of the air conditioner, turn it on automatically. The automatic operation of the air conditioner cools to the set temperature at first, and then maintains the indoor temperature through weak operation and air supply operation. However, when the outdoor temperature is not too high, or at night, switching on and off will be more economical.
According to the Ministry of the Environment, it is recommended that the summer room temperature be based on 28 degrees. The "room temperature" mentioned here is different from the "set temperature" of the air conditioner, so it is also necessary to adjust the setting temperature to 28 degrees.
As there are more energy-saving models of the latest air conditioners, sometimes you only need to replace the old air conditioners with new ones to save electricity bills. In addition, many manufacturers have set the standard useful life of air conditioners at 10 years, and if they use more than it, the probability of failure will be higher. The air conditioner has been in use for more than ten years. Let's consider replacing it.
When using the air conditioner, use the circulator together. Indoor air circulation helps to save electricity bills. When using air-conditioning, if the air-conditioned blinds (feathers on the exit) are kept horizontal, the cold air will hit the end wall near the ceiling and fall down.
The circulator is installed in the place where the cold air falls opposite the air conditioner and blows the wind to the air conditioner. As a result, the air circulation reduces the indoor temperature difference, and the air conditioner does not send out excess cold air, so electricity bills can be saved.
If there is something around the outdoor unit, the heat cannot be released effectively and the electricity bill will become higher. In particular, in order not to block the blow outlet, the lid of the outdoor unit should be made into a roof type, pull grass in advance, and adjust the environment.
If the air conditioner filter is dirty, the efficiency of the air conditioner will decrease, and it will cost extra electricity. Do a simple filter cleaning on the basis of once every two weeks.
Find a way to survive the heat.
There are many ways to save the cost of air conditioning. First of all, I want to start with what I can do. Find a way to control the electricity bill and spend the hot summer.
