In the hot summer, air conditioning has become an essential household appliance in our life. Although the air conditioning in summer is always cool, it is easy to turn around and feel sick in the air conditioning room for a long time. How can the air conditioning in summer work healthily?
When we use the air conditioner, we seldom pay attention to how much the air conditioner should be turned on, which is more suitable for the human body. We just set the air conditioner temperature lower when we are hot and higher when we are cold.
In fact, it's easy for people to catch a cold if the air conditioner changes the temperature setting too frequently. According to the type and brand of air conditioner, we have different methods of setting the temperature. Now let's see how many degrees the air conditioner is suitable for in summer, and at the same time, it can save more power.
How much is the most suitable air conditioner in summer
When the ambient temperature is 25 ℃, the relative humidity is 50%, and the air velocity is 0.15 M / s, the human body is in the most normal and ideal heat balance state, that is to say, the feeling is the most comfortable and the reaction is the best.
In fact, the effective temperature felt by the human body is slightly lower than the indoor air temperature, generally about 1 ~ 2 ℃, that is, although the air supply temperature of the air conditioner is slightly higher, the actual temperature felt by the human body is not so high. Therefore, the control temperature of the air conditioner is adjusted to about 27 ℃, at this time, the feeling of the human body will be more comfortable.
The temperature difference with the outdoor should not be too large
When the air conditioner is turned on in summer, the temperature difference between indoor and outdoor shall not be too large, which is generally 5 ℃ ~ 10 ℃. If the temperature difference is too large, people will suffer from sudden changes in temperature when they enter or leave, and they are prone to cold and other diseases.
In summer, when the indoor temperature is controlled too low, for example, below 20 ℃, people live and work in a low room temperature for a long time, which will cause a variety of discomfort, some people will have lower limb pain, general fatigue, cold, headache, sore throat, abdominal pain, backache, limb neuralgia.
How much is the air conditioner on in summer
In general, when the air conditioner is cooled, adjust it to 2 ℃ higher. Although the human body doesn't feel obvious, it can save nearly 10% electric energy on average for the air conditioner.
For example, if the temperature of the air conditioner is adjusted to 27 ℃ and compared to 20 ℃, the power consumption ratio will be 7:20, that is to say, when the temperature of the air conditioner is adjusted to 27 ℃, it can save about 30% of the power when compared to 20 ℃.
Setting skills of variable frequency air conditioning and constant frequency air conditioning
The temperature regulation of variable frequency air conditioner and constant frequency air conditioner is also different when they are in use. When they are in use, the variable frequency air conditioner quickly refrigerates when they turn on the air conditioner at the beginning. After reaching the set goal, they will maintain a certain amount of refrigeration capacity and keep the indoor temperature unchanged. The cooling speed of the constant frequency air conditioner is relatively slow compared with the frequency conversion air conditioner. When the constant frequency air conditioner reaches the set temperature in the room, it will automatically shut down and save electricity to maintain the temperature.
Summer air conditioning power saving tips
Tips 1. 26 ℃ - 28 ℃ is the best
In summer, for people who sit still or are doing light work, the most suitable indoor temperature is generally between 26 ℃ and 28 ℃. When the room temperature is set, the temperature difference between the air conditioner on and the outdoor temperature is generally within 10 ℃. For example, if the outdoor temperature is 30 ℃ and the indoor temperature is 25 ℃, it is OK. If the temperature difference is too large, it is easy to cause air conditioning diseases. In addition to summer, the heating temperature setting of air conditioning in winter also has its own stress. In winter, energy saving is 10% for every low 2 ℃ and more than 10% for every high 2 ℃ in summer.
Coup 2. The most power consumption when the air conditioner is started
The air-conditioned family should make full use of the timing function, so that the air-conditioner will not run all night, and can maintain a certain indoor temperature. Generally, it starts at 12 p.m. and can be set for 4 hours. Households who do not purchase air conditioners should purchase variable frequency air conditioners, which can reach the indoor set temperature in a short time, and the compressor will not be opened frequently, so as to achieve the purpose of energy saving and cooling.
Coup 3. The temperature of air conditioner should not be adjusted too low during use
Because the lower the temperature controlled by the air conditioner is, the more electricity will be consumed. Therefore, it is generally enough to reduce the indoor temperature to 26-28 ℃. When cooling, the room temperature is set to be 1 ℃ higher, and when heating, the room temperature is set to be 2 ℃ lower, which can save more than 10% of the electricity. However, the human body can hardly notice the slight difference.
Coup 4. Reasonable installation of air conditioner outdoor unit
The outdoor unit of air conditioner shall be installed on the shady side of the room as far as possible to avoid direct sunlight on the body. If this condition is not met, the outdoor unit of air conditioner shall be covered with sunshade; at the same time, less opening of doors and windows can reduce the heat entering outside the room, which is conducive to power saving; the actual length of internal and external connecting pipes shall not exceed the recommended length, which can enhance the refrigeration effect.
Summary: the above is the related introduction of air conditioning temperature setting skills in summer. Generally speaking, it is the most comfortable for the body to turn on the air conditioner from 26 ℃ to 28 ℃, and this temperature also saves electricity. In addition, the minimum temperature of turning on the air conditioner should not be lower than 22 ℃, the indoor and outdoor temperature difference should not be greater than 7 ℃, and the night air conditioner should not be lower than 24 ℃. Because if the air conditioner is turned on too much and the indoor temperature is too low, it is easy to suffer from "air conditioning disease", such as cold, cough, fever, depression, etc.
