In the hot summer weather, air conditioners and electric fans are essential electrical appliances, but using air conditioners all day will make people feel very dry, so many people choose to use electric fans. Compared with air conditioners, electric fans consume less power, but do you know how much power is generally used for household electric fans? How much electricity does an electric fan consume at night? Come and find out with me. What is the power of the electric fan in general
The power formula is: P=UI, P is the power of the motor, U is the voltage, and I is the current.
Before the calculation, use a multimeter to measure the current and voltage used, and then use the formula to calculate.
The specifications of the electric fans are different, and the power is generally 35W-60W.
Different home appliances often correspond to different powers. Commonly used electric fans are 12 inches (30cm), 14 inches (35cm), 16 inches (40cm) and other sizes. The larger the fan is , The larger the motor, the 12-inch is about 30W, the 14-inch is about 40W, and the 16-inch is about 50W. The price of electric fans is based on grades, small fans are 20-30 watts, table fans are 30-50 watts, floor fans are 30-70 watts, and black iron fans are 100-250 watts.
Household use is generally between 20W-100W, and industrial exhaust fans are generally between 0.37-1.5 kW, divided into four types: 0.37, 0.75, 1.1, and 1.5 kW. High-power industrial exhaust fans still consume electricity. Rather powerful. Calculated with a maximum 1.5kW industrial exhaust fan, each exhaust fan consumes 1.5 degrees of electricity per hour.
How much power an electric fan consumes at night
It depends on the power of the fan and the adjusted wind speed.
The power of the general fan is about 50W, the power consumption of the high-speed gear is 20 hours, and the power consumption of the low-speed gear is relatively small. How much power an electric fan consumes at night depends on the power. The power of ordinary electric fans on the market is generally 40 watts/h-150 watts/h.
One kilowatt hour of electricity is one kilowatt hour. If the power of the electric fan is 40 watts/h, then 0.94 kWh of electricity is used 24 hours a day. If the power of the electric fan is 100 watts/h, then 24 hours a day Just use 2.4 kWh of electricity. If the power of the electric fan is 150 watts/h, then 3.6 kWh of electricity is used 24 hours a day. The power of the electric fan is 50 watts, and the electricity consumption for 24 hours a day is 24 hours multiplied by 50 watts, which is equal to 1200 hours.
Electric fan power saving method Choose professional products Due to the low technical threshold of the fan industry and the uneven products on the market, you must choose products from well-known brands, so that Can guarantee the quality. The power consumption of the electric fan used with the air conditioner is very low. When the electric fan is used together with the air conditioner, the temperature of the air conditioner is set at 26℃-28℃, which not only saves electricity but also saves money. When using it, the fan should be placed next to the door and window to facilitate air circulation, improve the cooling effect, shorten the use time and reduce power consumption. Pay attention to the maintenance of the electric fan. Usually pay attention to the maintenance of the fan, maintain its good performance, and avoid the deformation and vibration of the fan blades, which is also conducive to the saving of electric energy to a certain extent. Buying skills for household electric fans
See the accompanying documents
The accompanying documents for each electric fan include instruction manuals, product certificates, electrical wiring diagrams and packing lists. When purchasing, check and check the quantity and quality of parts according to the packing list.
See if the grille and fan blades are visibly deformed
On the assembled electric fan grille, use a pen to point to a fan blade highest Point, move the fan blade slowly, the distance between the corresponding points of the other fan blades and the tip of the pen should be very close, and then turn the fan blade, pay attention to observe whether the rotation is brisk and flexible, and can stop at any position.
See if the control mechanism is flexible
The control mechanism includes speed control switch, timing knob, rocker switch, light switch, etc. These control mechanisms should be flexible in operation , The contact is reliable. For the speed control gear, it is not allowed to have two gears connected at the same time or the phenomenon that the first gear cannot be pressed. Press the stop button, and each speed gear button should be reset normally.
Look at the performance of the active part
The fan head of the electric fan runs flexibly at various angles of pitch and pitch, locks firmly, and adjusts to the maximum pitch angle or shakes the head to the final position , the grille shall not touch the fan struts. When the fan is running, the stability is better, it cannot be tipped over, and the shaking angle should not be lower than 60-80 degrees.
