How to save electricity with air conditioning?

The setting of air conditioning temperature should be reasonable. Experts pointed out that when using air conditioning, it is not advisable to set the temperature too low. In summer, the set temperature of domestic air conditioner is generally 26℃~27℃, and the indoor and outdoor temperature difference is preferably 4℃ ~ 5℃. Every time the air conditioner increases 1℃, the power load can be reduced by 7% ~ 10%. In fact, replacing long sleeves with short sleeves, changing suits into casual clothes, changing ties into loose ties, and properly raising the temperature of air conditioning will not affect comfort, but also save energy and reduce emissions. If each air conditioner is increased by 1℃ on the basis of 26℃ advocated by the state, each air conditioner can save 22 degrees of electricity every year, and correspondingly reduce carbon dioxide emissions by 2 1 kg. If this measure is taken for 65.438+0.5 billion air conditioners in China, it will save about 3.3 billion kWh every year, and correspondingly reduce carbon dioxide emissions by 36.5438+0.5 million tons. Proper indoor and outdoor temperature difference can also prevent the occurrence of "air conditioning disease". The sleep function of air conditioners should be used when sleeping, that is, air conditioners will automatically raise the indoor temperature after people fall asleep for a certain period of time, and some air conditioners are defined as economic functions. When sleeping, the heat emitted by the human body is reduced, and the metabolic amount is reduced by 30% ~ 50%, which is insensitive to temperature changes. Raising the temperature by 2℃ can save electricity by 20%. For people who sit still or do light work, the acceptable indoor temperature is generally 27℃~28℃. By the way, it is a bad habit to sleep with the air conditioner on, which not only consumes electricity but also easily leads to facial nerve paralysis. Therefore, it is best not to use it all night. You can use the "sleep" function and make full use of the timing function, which can save a lot of electricity. It is forbidden to turn the air conditioner on and off without restraint. It is best to keep the compressor from overloading every 2-3 hours to prolong the service life of the air conditioner. Whether the air conditioner saves electricity mainly depends on the number of times it is turned on, because it consumes the most power when it is turned on, so we should make full use of the timing function so that the air conditioner will not run all night and maintain a certain indoor temperature.

Cleaning the air conditioning filter can save electricity. The filter screen at the air inlet of the air conditioner is used to filter the dust entering the air conditioner. If the dust on the filter screen accumulates too much, it will increase the airflow resistance into the air conditioner, increase the load of the air conditioner, and naturally increase the electricity consumption. Generally, there is much dust in the north. If it is not cleaned for one month, the dust accumulated on the surface of the filter screen may be 1mm thick. If a 1000 watt air conditioner is used for 5 hours every day, it will consume about 5 degrees of electricity, and it will consume about 5% more electricity due to dust. If you consume 0.25 kWh per day, you will consume about 25 kWh more in the whole summer. At the same time, because all kinds of harmful bacteria may be adsorbed in the dust, which is not conducive to human health, air conditioners should be cleaned before the arrival of summer, which is both energy-saving and hygienic. If there is too much dust on the filter screen, it can be cleaned with warm water not exceeding 45℃. In addition, refrigerators and water-saving trays should be cleaned and wiped, which can not only save energy consumption, but also prevent air conditioners from breeding bacteria; If conditions permit, you can also ask professionals to clean indoor and outdoor heat exchange fins regularly. If you can do the above, you can save 30% electricity.

Don't switch the air conditioner on and off frequently. Some people think that the air conditioner is always on, which consumes a lot of electricity. Just open it for a while and close it for a while. In fact, it needs more electricity. Why? Because the air conditioner runs at high frequency when it is started, the instantaneous current is large, which will consume the compressor, so don't adjust the room temperature by frequent switching. The correct use method is: if the outdoor temperature is 30℃, the indoor temperature is set to 26℃~27℃. Don't adjust the temperature too low when the air conditioner is in use. The lower the temperature, the greater the power consumption. When the room temperature is set to 1℃ for cooling or 2℃ for heating, it can save more than 10% of electricity, but the human body can hardly notice this subtle difference. During the operation of the air conditioner, if it is not cold enough, the set temperature can be lowered by several degrees, so that the high-frequency operation time of the air conditioner is short, so it saves electricity; If you feel too cold, don't turn off your phone, just turn up the set temperature. Set high cold/high heat at startup to control the temperature as quickly as possible; When the temperature is suitable, changing to medium and low wind speed can reduce energy consumption and noise.

Select the dehumidification function to save electricity. The humidity of air-conditioned rooms also has a great relationship with energy saving. Sometimes the weather is sultry and uncomfortable, so there is no need to lower the temperature of the air conditioner again. At this time, the air conditioning mode can be adjusted to dehumidification state to reduce the indoor humidity, so that even if the relative temperature is slightly higher, people will feel comfortable and cool. Moreover, if the indoor air humidity is too high, it will also increase the workload of the air conditioner. In addition, the "ventilation" switch cannot be in the normally open state, otherwise it will increase the power consumption by 5%~8%, because turning on the wind switch frequently will lead to a large amount of cold air flowing out. It is best to turn off the air conditioner when the temperature is low in the morning, which can not only save electricity, but also adjust the indoor air.

Blowing air conditioning at the door is the most energy-saving. In order to improve the cooling effect, the doors and windows, ceiling and floor of air-conditioned rooms must be sealed to the maximum extent. It is best to blow the cold air of air conditioner at the door, because it can resist the hot air coming in from the door. If the air conditioner is installed next to the door, the hot air leaked when the door is opened will be quickly taken out of the room by the cold air blown out by the air conditioner, which will increase the heat load of the room and reduce the cooling effect. In addition, the periphery and mounting frame of the window air conditioner must also be sealed to prevent the outside hot air from leaking into the room and losing the refrigeration capacity.

When you turn on the air conditioner, you should close the doors and windows. Do not open doors and windows frequently in air-conditioned rooms to reduce the infiltration of hot air and the cooling burden of air conditioners. When using air conditioning, you can change the indoor air in advance, for example, open the window for ventilation when the weather is cool in the morning. If you feel that the indoor air is not good during the use of the air conditioner and want to open the window, it is recommended that the window opening gap should not exceed 2 cm, but it is best not to open the door as much as possible.

Please unplug the plug in time after use. After each use of the air conditioner, it is necessary to unplug the power plug in time, or unplug the power socket of the air conditioner, or modify the power socket of the air conditioner into a switch. After turning off the air conditioner with the remote control, the switch on the socket should be turned off again. Otherwise, even if the air conditioner is turned off, the power transformer is still connected, and the no-load current on the line not only wastes a lot of electricity, but also may cause an accident if it encounters a thunderstorm.

Turn off the air conditioner before going out. Turn off the compressor (from refrigeration to gas supply) 30 minutes before leaving home; 3 minutes before going out, the air conditioner should be completely turned off. Because the air conditioner is off, the temperature of the room will not rise immediately. During this time, the room temperature is enough to make people feel cool. Turn off the air conditioner 3 minutes before going out, and conservatively calculate that each unit can save electricity by about 5 degrees per year, and correspondingly reduce carbon dioxide by 4.8 kilograms. If this measure is taken for10.50 billion air conditioners nationwide, it will save about 750 million kwh of electricity every year, and correspondingly reduce 720,000 tons of carbon dioxide emissions.

Use air conditioning scientifically and healthily. Excessive use of air conditioning not only consumes energy, but also has adverse effects on human body. Some large offices use central air conditioning, with few windows and poor air circulation. People who work here rely on air conditioning to adjust the temperature for 8 hours a day, and the temperature is extremely low, which leads to a great temperature difference between indoor and outdoor. This is a kind of damage to the human body's ability to naturally coordinate body temperature. After a long time, it will cause this disorder, and it is easy to get the so-called "air conditioning disease", which is often manifested as colds, skin diseases, arthritis, gastrointestinal diseases and so on. So, don't rely too much on air conditioning. It is good for you to sweat more and give full play to your body's temperature regulation ability.
