In the hot summer, the fan is buzzing, and the cicadas are chirping all night long, how to clean you

In the summer, if there are a lot of trees outside the house, you will find that you can feel very irritated at night. Because there will be a lot of cicadas on the treesAt night, the sound of the loud cicadas will also make you feel very painful, in fact, at this time, you can use some ways to make your ears reach the state of mind.

In fact, many people nowadays do not plant room glass when they first decorate their housesBut in fact, in the process of subsequent use, you will find out how important the glass of the room is. A soundproof glass can well isolate the outside noise to ensure that you will not be disturbed by any sound while resting in the house.

Therefore, when you find that the noise outside has seriously disturbed your rest, then you can choose to replace it with soundproof glass, in fact, most of the soundproof glass is very good. After installation, a lot of sound from the outside can no longer be transmitted to the room, so it can also make your ears clean.

In addition to this way, in fact, buying some heavy curtains also has a more important roleThis is due to the fact that heavy curtains can actually act as a barrier. When the curtains are thicker, it is actually difficult for these sounds to come through the curtains.

In addition, when sleeping at night, you must carefully close the window tightly, and take care of the breeze of the window carefully, and you can use some sealing strips to seal the cracks of the windowThis prevents outside sounds from entering the room, so that you can ensure that your ears are clear.

You can wear earplugs to block noise, and you can also install soundproof glass, and if you have an air conditioner, you don't need to turn on the fan, which also reduces noise.

You can choose some heavy curtains, which can not only block the light and wind, but also block a certain sound, and if you have an air conditioner, don't blow the fan, and it can also reduce the noise.

If you have a fan, you can turn on the air conditioner, and then it won't buzz, and if the cicadas chirp, you can't completely eliminate it, after all, it's impossible to tear down the house and reinstall the soundproof wall.

Don't turn on the fan when it's hot for the first time, it is recommended that you blow the air conditioner, be sure to enjoy it in time, and the second is to prepare mosquito coils and there will be no mosquito coils.

It is better to install more soundproof doors and windows at home, so that there will not be so many things.

You can stuff things in your ears, but the best thing to do is to buy glass that is better insulated.

Install an air conditioner in your home so you don't have to turn on the fan, and then replace the window glass with a soundproof one, plus a seal.

You can install an air conditioner, so you can't hear the fan, and the glass can be installed with good sound insulation, so that you can isolate other sounds.

1. Computer heat dissipation.

Usually when we copy the computer, BAI has a cooling fan to dissipate the CPU of the computer.

Du this is Bao Zhi

A way to protect your computer. Because the computer will produce heat after a long time of DAO use, if the heat cannot be dissipated in time, it will cause the CPU temperature to be too high and cause automatic shutdown or blue screen of death, affecting normal use. In severe cases, it will also burn out the CPU and increase the cost of maintenance parts.

2. Car cooling.

There will also be cooling fans installed in the car. Because the car will convert mechanical energy into heat energy during driving, so that the internal temperature of the car will rise, in order to ensure that the parts inside the car are not burned out, a cooling fan is needed to cool down and dissipate heat, so as to ensure that the parts are within the normal temperature and do not fail.

3. Industrial production.

Generally, industrial cooling fans are used in the production equipment of the factory. Due to the production environment, many equipment works in a workshop with heavy dust and weak ventilation, and long-term use will make the equipment accumulate a lot of debris and dust, which can not effectively dissipate heat. The use of cooling fans can solve these problems well, cool down and remove dust for the equipment, enhance ventilation, and effectively extend the service life of the equipment.

In addition, cooling fans can also be used in communication equipment, purifier industry, UPS power supply, medical equipment and many other industries, with a wide range of applications and a huge market scale. The content introduced above is the application field of DC cooling fan, in fact, the application field of DC cooling fan is very extensive, and the above is just the part of our life that we are more commonly contacted!

The AC power supply can be used as a desktop fan, and the DC power supply can be used for small production.

For example, when using a computer, or other electrical appliances with poor heat dissipation functions, you can also use them.

1. The plugs and sockets of household appliances must be in good contact to save electricity, otherwise it will increase power consumption and may damage electrical appliances.

Second, the scale accumulated in the electric heating pipe of the electric kettle should be eliminated in time to improve the thermal efficiency, prolong the service life, and save electric energy.

3. The room using the electric heater should be sealed as much as possible to prevent heat loss. After the room temperature reaches the requirements, the power should be turned off in time.

Fourth, ironing clothes is best to choose a temperature control electric iron with a power of 500w or 700w. This type of iron heats up quickly and can reach the temperature of use.

Automatic power cut-off not only saves electricity, but also ensures the quality of ironing clothes.

5. If the fabric of the ironed clothes is not exactly the same, the chemical fiber clothes with low temperature resistance should be ironed first, and then ironed with higher temperature resistance after the temperature rises.

of cotton and linen fabrics. After the power is off, the waste heat can also be used to iron a part of the chemical fiber clothes.

6. The power consumption of the electric fan is directly proportional to the speed of the fan blades. On the premise of meeting the requirements of use, use medium and slow gears as much as possible. Such as 400 mm.

Fan, the power consumption of the fast gear is 60W, and the slow gear is only 40W.

7. For air conditioning, it is advisable to set the room temperature at 27 to 28, and when the air conditioner is turned on, the doors and windows should be closed; Clean the dust filter regularly to save money.

30% electricity; Do not start it frequently, and turn it on again after 2 to 3 minutes after the shutdown.

1. Turn off the lights casually, turn off the lights when people go, and avoid "ever-bright lights".

2. Make full use of natural light, please do not use lighting when natural light can meet the requirements.

3. The selection of lamps and lanterns should be reasonable, and try to use less or no frosted glass and translucent lampshades that obstruct the light of the light source.

4. Multi-use energy-saving lamps, the use of energy-saving lamps can save electricity by 70% and 80%; Correctly select the lamp power, where 60 watt incandescent lamps were originally used, now 11 watt energy-saving lamps are enough.

5. When household appliances are not in use, do not be in standby mode, please turn off the power switch in time, which can save about 10% of electricity.

6. Reasonable use of refrigerators can reduce power loss. Reduce the number of refrigerator doors opened; Don't pile up the food in the refrigerator too much or too densely; The refrigerator should be placed in an appropriate position, away from heat sources, and there should be space around it; Clean the refrigerator in time, remove the frost layer on the inner wall of the refrigerator, etc.

7. Reasonable use of washing machines can reduce power loss. According to the type of laundry, select the function switch, and try to use the strong washing function as little as possible; Clothes should be washed in a centralized manner as much as possible, and the laundry in the washing bucket should be as close as possible to the maximum washing capacity to reduce the number of clothes put in; For about 3 years, I inspect and tighten the wheel axle belt of the washing machine.

8. Reasonable use of air conditioners can reduce power loss. Clean the air conditioning filter in time to maintain the air volume of the outlet and inlet to improve the refrigeration effect; Set the temperature of the air conditioner reasonably to reduce the running time of the compressor, etc.

9. Properly adjust the volume and brightness of TV, computer, audio, etc., which can also achieve the effect of saving electricity.

The effect of kilowatt-hour electricity (one kilowatt-hour of electricity).

The 25-watt bulb will light up for 40 hours continuously.

A home refrigerator can run for a day.

Ordinary electric fans can run continuously for 15 hours.

1 hp air conditioner can be turned on for hours.

It can boil 8 kg of water.

The TV can be turned on for 10 hours.

The electric shower is available for one bath.

Saving 1 kWh of electricity is equivalent to: saving kilograms of standard coal and saving 4 liters of water.

Generating 1 kWh of electricity will emit toot: kilograms of carbon dust, kilograms of carbon dioxide, kilograms of sulfur dioxide, kilograms of nitrogen oxides.

1. Use energy-saving lamps, and turn off the lights when people walk, develop the habit of turning off the lights in time, start from the details, and save every kilowatt-hour of electricity.

2. Unplug the power supply of household appliances in time when they are used up, and unplug the charger when the mobile phone is not charging, and the same is true for other electrical appliances.

3. Do not turn on the air conditioner below 26 ° in summer, which not only protects health but also saves electricity.

4. The use of solar water heaters, this is a very good invention, I hope that the use of solar energy will become more and more extensive in the future, timely replacement of old electrical appliances, such as old lamps, electric kettles, etc., old electrical appliances have been used for a long time, the resistance will become larger, and the power consumption will become larger, and the timely replacement of these old electrical appliances can achieve the purpose of saving electricity.

In addition to the correct use of power-saving switches in the use of refrigerators, it should also be noted that the food in the box should not be too full and too dense, so as not to obstruct the circulation of cold air and cause the refrigerator to not refrigerate; On the contrary, there should be no space in the refrigerator, for example, too little food in the refrigerator will cause the loss of cold air. In addition, the number of refrigerator door openings and the opening time should be minimized, and non-frost-free refrigerators should also be defrosted regularly and the condenser should be dusted regularly, so as not to affect the refrigeration effect and waste electricity.

At home, you'll have a lot of things to do with our loving breakfast.

Nowadays, rice cookers have become a must-have kitchenware in many homes. On the one hand, it brings convenience to people's lives, and on the other hand, it also increases household electricity consumption. In my daily life at home, I gradually found some tips to save electricity when cooking, and I took them out here to communicate with my friends.

First of all, you should choose a rice cooker with the appropriate power. Practice has proved that it takes 30 minutes to cook 1 kg of rice, and a 500-watt rice cooker consumes kilowatt-hours; The 700-watt rice cooker takes about 20 minutes, and the power consumption is only kilowatt-hours.

Secondly, if there are stains on the surface of the electric heating plate and the bottom of the pot, they should be wiped clean or gently sanded with fine sandpaper to avoid affecting the sensing efficiency and wasting electrical energy.

Third, when using a rice cooker, it is best to wash rice in advance, cook rice with boiling water, and use boiling water to cook rice at the standard of cooking rice. Unplug the rice as soon as it is cooked, otherwise, when the temperature in the pot drops below 70, it will automatically power on intermittently, which will consume electricity and shorten the service life of the rice cooker. When cooking rice in a rice cooker, covering the rice cooker with a towel can reduce heat loss.

In addition, when cooking rice, the power can be cut off for 7-8 minutes after the water boils, and then the power can be turned on again, so that the waste heat of the rice cooker can also be fully utilized to achieve the purpose of saving electricity.

Xu Weilin, a professor at the State Key Laboratory of Hydraulic Engineering and Mountain River Development and Protection of Sichuan University, will teach you a few tips on daily electricity use:

The power consumption of the electric fan is directly proportional to the speed, and the medium or slow gear should be used as much as possible, and the slow gear can save one-third of the power compared with the fast gear; Turn on the brightness of the TV to a smaller level, which not only saves energy, but also prolongs the service life;

Refrigerators should be placed in a cool, well-ventilated place, and when used, the number of door openings should be as few and short as possible; The temperature adjustment in the box should be appropriate; Store food should not be too full or too tight to reduce electricity consumption; Hot food should be cooled to room temperature naturally and then placed in the refrigerator to reduce electricity consumption; Defrost promptly. so as not to increase power consumption.

The louder the TV and the brighter the screen, the more power it consumes. Use a dust cover when shutting down. Adding a dust cover can prevent the TV from absorbing dust, and if there is more dust, it may leak electricity and increase power consumption. When the TV is not watching, unplug the power plug, and the whole machine is still using electricity when it is in standby.

Wrap a ball of cotton on the drip funnel of the refrigerator, and then wrap it with string or adhesive tape, which can prevent direct communication between cold and heat, so as to achieve the purpose of saving electricity;

The air conditioner sets the temperature up by a few degrees, and sleeps more; Otherwise, even if the switch on the machine is disconnected, the power transformer will still be connected, and the no-load current on the line will not only waste electric energy, but also sometimes cause trouble.

Common faults of electric fans.

1.The fan does not start properly.

Cause (1) Poor connection of shaded pole winding; The stator windings are open. (2) The two bearings of the fan are too tight; The rotor collides with the stator. (3) The rotor cage is broken or the cage is welded; Damaged capacitors; The power cord is disconnected.

Solution (1) Check the winding contact, restore its contact, and ensure normal operation; Check whether the stator winding is passed, and rewind if necessary to avoid the problem of short circuit. (2) Lubricating the two shafts or replacing the bearings; Adjust the stator-rotor gap to avoid friction damage. (3) Check the rotor cage strip and repair or replace it; Replace capacitors; Check the power cord and restore power.

2.The fan sometimes turns, sometimes it doesn't.

Cause (1) The incoming line is damaged or broken; Poor soldering of the connecting wire. (2) Poor contact of the internal components of the switch; The main and auxiliary windings are broken or touched;

Solution (1) Check the incoming line and restore the normal power-on; Check the cable so that it is in good contact. (2) Check the switch components to ensure normal contact; Measure whether the main and auxiliary windings are connected, if not, replace the windings.

3.The fan speed is slow.

Cause (1) The plane bearing of the ceiling fan is damaged or lacks oil; The ceiling fan rotor sinks. (2) The power supply voltage is too low; Winding inter-turn short circuit. (3) The capacitor is damaged; The slope of the blades is too large.

Solution (1) Replace the plane bearing, add lubricating oil, reduce friction and prevent damage; To restore the original position of the rotor, it is necessary to reinstall the adjustment. (2) Adjust the power supply voltage so that it reaches or approaches the rated voltage; Test windings and replace them in case of turn-to-turn short circuits. (3) Test capacitors, if damaged, directly replace the capacitors of the same type and capacity; Adjust the slope of the blades.

This year's summer is coming, do you have fans, air conditioners and other refrigeration appliances, if not, you can prepare; At present, you can still use electric fans, individual weather is hotter and need to use fans, there will be some faults that need to be dealt with, when encountering failures, general repairers should carefully investigate, and then repair according to the corresponding problems, when dealing with common faults of electric fans, first collect all the phenomena, lock a variety of possibilities, then eliminate, and finally repair, if you still don't want to spend too much time to repair, or will not repair, it is recommended to find professionals to repair more secure.
