Here are some guidelines for electricity bills and ways to judge the electricity bill of a fan.

How much does the electricity bill of a fan cost in one month?

It is convenient to check the type of motor to determine the standard of electricity bills on the fan.In general, fans can be broadly divided into DC motor models and AC motor models.Let's look at each characteristic.

■ DC motor model

The DC motor model is a model that is common in recent fans.DC current is a DC current, and the voltage is always constant and only one direction flows.The air volume can be adjusted finely even at low speed rotation, and the wind can be blown while reducing the burden on the body.

In the case of a DC motor, the power consumption is 1.It is about 5 to 20 watts, and the electricity bill per hour is 0.04-0.It is about 54 yen.12 hours a day or 30 days, the electricity bill is 14.4-194.It will be about 4 yen.

■ AC motor model

The AC motor model is a system that is common in old models and is an AC current type.There are many types of air volume settings, such as three stages of weakness, middle, and strong, but the main unit price is suppressed compared to DC motor models.

In the case of AC motor models, the power consumption is about 10 to 37 watts, and the electricity bill per hour is about 0..27-11.00 yen, the burden on the electricity bill is greater than the DC motor model.12 hours a day or 30 days, the electricity bill is 97.2-359.6It will be about 4 yen.

■ Circulator

Circulators (blower), which are used for a fan similar to that fan, have a basic structure almost the same as the fan, but can be blasted at various angles.

The maximum power consumption of the circulator is about 21 watts.The electricity bill per hour is about 0.It is 57 yen.12 hours a day, 30 days, 205 electricity bills.It will be about 2 yen.

How to judge the electricity bill for a fan?

To determine how much the electricity bill costs a fan, check the power consumption of the fan.The electricity bill depends on the power company's plan.

Depends on the wattage

The electricity bill required for the use of a fan varies depending on the number of watts.By the National Home Electrical Product Fair Trade Council, the electricity bill for using home appliances is 27 yen (tax included) per 1 kWh, so it can be calculated based on that.

For example, if a fan with a power consumption of 10 watts is used 12 hours a day or 30 days a day, the electricity bill for 1 hour is about 0..27 yen, 97 in one month.It is about 2 yen.

The unit price differs depending on the plan of the contracted power company

The electricity bill for the use of home appliances, which costs 27 yen (tax included) per 1 kWh, is a guide, and varies depending on the plan of the contracted power company.

For example, if you have contracted for electricity with TEPCO's smart life S, the power rate between midnight to 6:00 is 17..It is 78 yen/kwh.If you use a 10W fan, the 1 hour electricity bill is about 0.It will be about 18 yen.

In other words, the lower the electricity fee, the lower the electricity bill.

Comparison of electricity and air conditioning electricity bills

Let's compare the electricity bills for the use of a fan and the air conditioner.

Air conditioner electricity bill

The power consumption of the air conditioner depends on the cooling ability.The power consumption during the cooling period is about 150-250 kWh, so if the electricity bill is calculated as 27 yen (tax included) per 1 kWh, the electricity fee per hour is 4..05-6.It is about 75 yen.

Air conditioner electricity billは下がっている

Energy -saving performance of home appliances, including air conditioners, is increasing year by year, and the electricity bill for air conditioners is declining year by year.

Comparing the amount of electricity consumption in 2010 and 2020 (electricity used when driving air conditioners using cooling and heating) is reduced from 872 kWh to 808 kWh.Although the unit price of the electricity bill is different, it is considered that the burden on the electricity bill has decreased because the power consumption is reduced by nearly 10%.

The electricity bill of the fan is cheaper

If the electricity bill of the air conditioner is calculated as 27 yen (tax included) per 1 kWh, the electricity bill per hour is 4.05-6.About 75 yen.On the other hand, in the case of a fan, 0 per hour.04-11.It is about 00 yen.You can see that the electricity bill of the fan is cheaper than the electricity bill of the air conditioner.

How to save electricity bills using a fan

Using a fan well will save electricity bills.Here's how to use a fan to save electricity bills.

(1) Select a DC motor fan

The AC motor, mainly used in old models, has more power consumption, although the cost of the main unit is reduced compared to the DC motor.

If you want to reduce the electricity bill as much as possible, choose a DC motor fan that consumes low power.The air volume can be adjusted freely according to the situation, so it is less expensive.

(2) Use with the air conditioner

The lower the set temperature of the air conditioner, the higher the electricity bill.If the air conditioner and the fan are used together, the air in the room will circulate, so the temperature difference of the entire room will be reduced, and it will be comfortable even if the set temperature is high 1-2 times.

There is some data that the electricity bill has become cheaper when used together, so it is recommended to use it with a fan when using the air conditioner.

(3) Put a fan in a hot place in the house

There are some places in the room where the temperature is not easily dropped even if you use an air conditioner.The place may not have a good circulation in the air, so use a fan or circulator to circulate the air.It cools efficiently, so you can reduce the electricity bill.

The electricity bill of the fan is cheap! Let's spend comfortably with the air conditioner

The electricity bill of the fan is 0 per hour.04-11.About 00 yen.Air conditioner electricity bill 4.05-6.Because it is about 75 yen, you can see that the electricity bill of the fan is quite low.

The old model had an AC motor, but the new fan has many DC motor models.DC motor models have less power consumption, and can be blown even at low speed rotations, so the air volume can be finely adjusted, reducing the burden on the body.In addition, many people use a circulator with the same function.

On a hot day, using air conditioners and electric fans together will increase the power saving effect.In addition, in order to reduce the electricity bill, it is necessary to change the plan that matches your power used.Use a fan to reduce the electricity bill in summer.
