Do you know how to use air conditioners reasonably?

Since entering the three days, the weather in the country has entered the "simmering" mode. Recently, there was a hot news saying that an aunt in Hangzhou did not open the air conditioner in order to save money. The online section of the hand is even poorer: "The bed is braised, the mat is teppanyaki, the bed is steamed, and the door is barbecue." Someone said: "We want to thank the inventor of the air conditioner, because this life is It is air-conditioned." Recently, Xiaomi also made headlines with an Internet air conditioner. In addition to the simple suspension modern design, the air conditioner has the biggest selling point of 0.1 °C fine temperature control! Can your body surface really feel the room temperature change of 0.1 °C? You may say that I am more real, but it is worthy of praise that precision temperature control is not to be underestimated for energy saving. Because the saying goes, "the decimal is afraid of long-term", the modern air-conditioning frequency conversion technology has made people comfortable and air-conditioned. The power consumption is almost perfect.

The truth about air conditioning power consumption is actually frequent shutdown

Most people think that it is a good habit to turn off the lights when the household appliances are not used. For example, it is a good habit to turn off the lights. However, for air conditioners, this may not be the case. Frequent power-on and power-off will not only save power but will consume more power and will accelerate. The aging of your home air conditioner. Don't you believe it? I say this is valid.

The Japanese once did an experiment: testing the power consumption of air conditioners in different usage scenarios. As a result, the peak value of the air conditioner's power consumption appeared after about 3 minutes of startup, and the power could reach more than 1400W. After a period of high load operation, the room temperature of the test room dropped to the set 27 degree level. Then the power consumption of the air conditioner began to stabilize, about 238W. Therefore, if you go out for a short time, it is recommended to keep the air conditioner in the open state, because it takes a while for the air conditioner to go from stable to stable. At this time, the power is the biggest, but if you are going out for a long time, it is natural to turn off the air conditioner.

A similar experiment has been done in China: in two laboratories, the air conditioners are turned on in the same cooling mode, and the temperature is preset at 26 ° C. The air conditioner in one room is kept open, and the other room is imitated. Turn on-off-on cycle mode, and switch on and off every 5~10 minutes. The experiment time is half an hour. The results show that the air-conditioning power consumption of both modes is 0.24 degrees. However, since the actual running time of the air conditioner with repeated switching is only half, it can be seen that this method does not reduce the power consumption, but increases the power consumption.

"Sensual temperature" has deceived you for so many years.

With air conditioning for so long, have you noticed the word "dehumidification" on the remote control screen? Compared with “cooling”, “dehumidification” can also cool down, but changing the air conditioning mode from “cooling” to “dehumidifying” can not only make the room cooler, but also cost less, and the impact on the human body can also be reduced. To the lowest. You need to know the fact that the higher the humidity, the hotter the feeling. Having said that, you first need to understand two words, "weather temperature" and "body temperature."

"Weather temperature" is the temperature we often say, that is, the temperature reported in the weather forecast. "Sensual temperature" is the subjective temperature we feel, and it varies from person to person. One of the most important factors influencing the "body temperature" is relative humidity. The greater the humidity, the greater the difference between the somatosensory temperature and the actual temperature. When the weather is hot, the sweat glands of the human body are constantly producing sweat, and the dry air can quickly absorb the sweat, which makes us feel cool, but in the air environment with high humidity, because the air is already full of water, it is unable to absorb water. Then the sweat has to accumulate on the skin, causing the body temperature to rise. In an environment with high humidity in the air, it is more effective to reduce the humidity in the room than to reduce the temperature in the room.

Seven coups let you save the end

1. After the air conditioner is turned off, as long as the plug is not unplugged, it is still in a small power consumption. Therefore, don't be bothered, you should unplug the power supply after turning off the air conditioner.

2. In the sauna day, turn on the dehumidification function of the air conditioner, which is not only cool, but also can save less electricity.

3. The most suitable temperature for air conditioning is 26 ° C ~ 27 ° C, which is the most suitable for human body temperature, comfortable and power saving. Some people have done experiments. The temperature setting is 1 °C higher, and the power consumption is reduced by 7%~10%.

4. If you go out for a short time, it is best not to turn off the air conditioner, such as within 1 hour, so that turning on the air conditioner will save more power. The high voltage of 500~1000 watts generated when the air conditioner starts up will consume more power.

5. The cold air flow is heavier than the air and easy to sink. Therefore, when the air outlet is upward in cooling and the air outlet is downward in heating, the temperature adjustment efficiency will be greatly improved.

6. When using air conditioners, try to avoid direct sunlight in the room and air conditioners, especially in the summer, which can save about 5% of power consumption.

7. Set the air conditioner to sleep state before going to sleep. The operating frequency and wind speed of the air conditioner will be significantly reduced, and it will enter a quiet, comfortable and energy-saving state.

The ultimate power saving trick to turn off the air conditioner

I am not kidding, the air conditioner is good, but don't be too greedy. Have you heard of "air conditioning sickness"? In fact, "air conditioning disease" is only a common name, not a medical disease, generally refers to the general term of people suffering from dizziness, headache, joint pain, cold and fever and other related symptoms.

The outdoor temperature is high, and the air conditioner is too cold, resulting in a large temperature difference between indoor and outdoor. This is difficult for the elderly with poor resistance. The cold and fever often follow, and it is harmful to the elderly with cervical lumbar joint disease. Staying in the room where the temperature is too low every day, the cold moisture accumulates slowly in the human body, which is often the cause of the rough skin of the female spleen and stomach. If you blow more air conditioners, it will also cause "heatstroke", but it is not "yangshu", which is called "yin heat". It means that when the weather is hottest, because the air conditioner chills into the body through the sorrow, it brings harm to the body.

Doctors suggest that in the air-conditioned room, do not wait too long, the indoor temperature should not be lower than 26 ° C, daily ventilation should be regularly, do not let the cold air of the vent directly blow on the body, it is best not to blow directly when sweating Cold wind. When entering from outside, do not turn on the air conditioner immediately, and do not stay in the air-conditioned room for more than three hours. The most important thing is not to blow the air conditioner at low temperature all night. If the temperature is too low, the blood vessels will shrink excessively.
