Detailed explanation of how much energy is saved by air conditioning in summer
? How many degrees does air conditioning save energy in summer?
1. Increase the temperature 1℃ and save electricity 10%.
Don't covet the low temperature of air conditioner, just set the temperature appropriately. The optimum temperature of indoor air conditioning should be set at 25-28 degrees. For people who sit still or do light work, the temperature of the air conditioner can be slightly raised, because every time it is raised, it can save electricity by about 7%- 10%, but it has little effect on the body feeling.
The air conditioning temperature setting is too low, which is influenced by both people and machines in actual use. For air conditioning, temperature setting is equivalent to its working goal. When the actual temperature differs greatly from the target temperature, the air conditioner will work at full speed to make the room temperature reach the standard as soon as possible. If the temperature is set too low, the air compressor of the air conditioner will work with high power for a long time, which will have an impact on the life of the air compressor.
According to scientific research, the most comfortable temperature for human body in summer and autumn is about 26℃. Below this temperature, the human body will feel a little cold. If it is winter, the temperature that the human body feels warm is around 28℃, and it will feel slightly hot above 30℃. Therefore, even if you don't look at energy saving, from a health point of view, the indoor and outdoor temperature difference is best at 4 to 5 degrees Celsius in midsummer, which can also prevent colds caused by excessive indoor and outdoor temperature difference, which is also commonly known as "air conditioning disease."
Two, according to the different characteristics of frequency conversion and fixed frequency models, reasonable use.
It is generally believed that inverter air conditioners save more electricity. No! Inverter air conditioning can only play an efficient and energy-saving role if it is used continuously for more than 6 hours in a harsh environment. At the same time, constant-frequency air conditioners have made continuous technological breakthroughs. The high-efficiency and energy-saving products represented by brand-new air duct technology, high-efficiency arc evaporator technology and high-efficiency and energy-saving technology all meet the national energy-saving standards, and can also achieve the dual effects of optimal refrigeration and energy saving.
When the constant frequency air conditioner detects that the room temperature is basically equal to the set temperature, it will stop to save electricity and keep the temperature; The inverter air conditioner will maintain a certain cooling capacity at this time, and keep the constant temperature as much as possible. The ultimate goal of the above two methods is to keep the room temperature as constant as possible.
Based on this characteristic of the air conditioner, we can set the high temperature and low temperature at the fastest speed when starting the machine. When the room is completely cooled or heated, the machine will stop or reduce its power to save energy. If it is cooled or heated slowly, the compressor will be under high operating load for a long time, which is unfavorable to its life. Of course, many air conditioners have intelligently completed this process.
In order to save electricity, some people often turn on and off the air conditioner. In fact, frequent switching of air conditioners consumes the most power, and compressors are also prone to loss. When the air conditioner is running, if it feels too cold, there is no need to turn it off, just raise the set temperature. In addition, when we feel that the indoor temperature is suitable, we can change the air volume to medium-low wind to reduce energy consumption and noise.
Third, it is more energy-saving to use air conditioners with electric fans.
Generally, when you buy an air conditioner, you throw away the fan or seal it. In fact, it is a very good way to cool down with fans and air conditioners. When the air conditioner is turned on and the fan is turned on at the same time, it can not only get the feeling that the set temperature of the air conditioner is low 1-2 degrees, but also help the indoor air circulation and prevent the occurrence of "air conditioning disease".
Fourth, the number of air conditioners adapts to the size of the room.
Generally speaking, the price of air conditioner is directly proportional to the P number, but when buying it, you should choose the air conditioner according to the size of the room, so that the power of the air conditioner should be suitable for the room. In fact, when you buy a small air conditioner to save electricity and put it indoors, it is bigger than the design space of the product, and it will also have a great impact on the power consumption of the air conditioner. Its principle is consistent with the high indoor temperature, which will also increase the possibility of air conditioning failure.
The fifth and fourth generation arc evaporators save more electricity.
The traditional evaporator mostly adopts folding structure, and now it has developed to the fourth generation arc evaporator. Compared with the folding evaporator, its exchange area is increased by 15%-30%, the refrigeration speed is increased by 12%-25%, the noise is reduced by 1-3 dB, and the failure rate is greatly reduced. However, due to the high production cost and technical threshold, only a few manufacturers have used this technology at present. In addition, when selecting air conditioners, priority should be given to fluorine-free products with environmental protection and high energy efficiency. (Energy efficiency ratio is the ratio of refrigeration capacity to refrigeration power consumption)
Six, the use of air conditioning sleep function is more energy-saving.
Everyone's usual habit of using air conditioning may be to open it after entering the house, and the temperature is the lowest. So I ignored some other buttons on the remote control, such as the sleep mode that many air conditioners have, which is very suitable for sleeping at night. The air conditioner will automatically adjust the temperature, automatically increasing 1 hour every hour, and it will remain unchanged after two hours.
Reasonable use of sleep mode can not only save 20% electricity, but also prevent the harm caused by low sleep temperature at night. On the contrary, if the air conditioner remains cold when sleeping, you will get dizzy in the morning. Due to the different temperature requirements of human sleep time, more advanced air conditioners will fit the temperature curves of human sleep in different periods, thus obtaining a comfortable experience. Before waking up, the body temperature is low, so the room temperature should not be too low. Based on this, it can be set to shut down regularly. Turn off your phone one hour before you wake up, and you won't feel very hot when you wake up naturally.
Seven, clean up the dust net
Indoor mechanical refrigeration of split air conditioner adopts air internal circulation heating mode, that is, indoor air is continuously inhaled, heated and then blown out to improve the room temperature. Some air conditioners also add electric heating auxiliary design, which can make the air conditioner heat faster. However, after the fan runs for a long time, dust and dirt will affect the filter screen, resulting in poor air volume and refrigeration effect of the air curtain, reducing the service life of the air conditioner and increasing power consumption.
Eight, take a breath in advance, open doors and windows less.
Please change the air in the room in advance when you use the air conditioner. The air in the two-bedroom has completely changed, enough for two people to consume for an hour and a half. If windows are opened, it is suggested that the gap between windows should not exceed two centimeters. In the process of using air conditioning, we should control the opening of doors and windows as much as possible. If the inverter air conditioner is used, when the indoor temperature is always the same as the outdoor temperature, then the inverter air conditioner will increase the frequency, overload work and increase consumption. If you want to stop and get some air, you'd better turn off the air conditioner 20 minutes before opening the window.
Reducing the number of opening and closing doors and windows is indeed a very simple and effective method, but there are also negative effects. For example, if the air is not circulating, it is definitely not fresh, and the waste gas accumulated in the house is definitely harmful to the human body. According to some data, this is also one of the causes of air-conditioning diseases, so we suggest that you should change the indoor air every two or three hours.
Nine, choose the appropriate air outlet angle.
Using air conditioner to choose a suitable air outlet angle will make the temperature drop faster. When the temperature becomes lower, the cold air flow rate is easy to go down, and when cooling, the air outlet is upward, which has good cooling effect. In winter, the hot air is upward, and the air outlet should be downward when heating. This can also achieve the effect of energy saving.
The air conditioner should be placed in a proper place in the room. First of all, we should pay attention to air circulation, so that the heating effect of air conditioning can quickly cover the whole room. Secondly, the placement of air conditioners should pay attention to the sufficient space of air conditioners. For example, the outdoor unit should not be placed in the corner of the corridor, which will lead to cracks in the building and avoid the blockage of the air outlet, which will lead to poor ventilation of the air conditioner and increase power consumption; Choosing the right outlet angle can also save electricity. Because the hot air is floating, the air outlet of the indoor unit should face down when heating.
X. Regular maintenance of outdoor unit
The air conditioner first compresses gas into liquid by electric energy, then evaporates the liquid at the refrigeration end (endothermic process), and the evaporated gas is led back to the compressor and becomes liquid again (exothermic process), so that the heat keeps moving and achieves the purpose of refrigeration.
The outdoor unit is the most important part of the whole heating process, and its working principle is just the opposite of refrigeration. By evaporating the refrigerant, the outdoor air heat is pumped into the room, but if it is not used for a long time, the heat sink will accumulate too much dust, which will affect its heating efficiency (law of conservation of energy) or damage the compressor. Therefore, the outside of the compressor needs to be cleaned, especially the intake part of the suction. If something such as plastic bags is adsorbed, it should be cleaned up in time.
