Many people are concerned about how to blow the air conditioner is better for the body, but few people will be concerned about how to blow the fan is good.
The wind speed should not be too large
Modern science believes that indoor wind speed is best controlled at 0.2-0.5 m / s, especially in the better ventilated rooms and in places with excessive wind, the wind speed of the fan is not too large.
In addition, when the temperature exceeds 30 ℃, do not choose too large wind gear, because the wind blowing from the fan at this time is also high temperature. The body mainly relies on sweat evaporation heat dissipation, if the fan wind blowing too much, the skin surface temperature drops, pores closed, the body internal sweat does not come out, not only will feel hot, there will be fatigue and weakness, back pain, which is "holding sweat".
Not suitable for people blowing directly
straight blowing, wind evil easily invade the body, especially in weak or sweaty, it is best to let the electric fan towards a corner blowing;.
Electric fans should be blowing stop, it is appropriate to use the head of the electric fan, for children, the elderly, weak people, it is more appropriate to use the electric fan blowing wind, because "the coup of evil, its gas will be deficient", but can be used to adjust the indoor airflow of electric fans, to indirectly cool down.
Do not blow the fan immediately when sweating
To pay attention to sweating more, do not immediately in the case of sitting or lying down blowing wind, because at this time the whole body surface vascular expansion, suddenly by the cool wind blowing, often causing vasoconstriction, sweating immediately stop, thus causing the body to lose balance between heat production and heat dissipation, excess heat instead of excretion.
After the cool breeze, the local defense function decreases, viruses and bacteria invade, which can produce upper respiratory tract infections, muscle and joint pain, and some even abdominal pain and abdominal discharge.
Fan with air conditioning together
Because the fan can directly convert electrical energy into kinetic energy, power consumption is very low, the highest power is only 60W, equivalent to the power consumed by ordinary lighting lamps. Therefore, from the perspective of energy saving, the use of fans in the summer season is undoubtedly the best choice. The fan is used together with the air conditioner, and the air conditioner temperature is set at 26 degrees - 28 degrees, which saves electricity and money.
Try to use medium or slow gears
In terms of the use of the fan itself, the general fan blade is large, the electrical power is large, the consumption of electricity is also more, the power consumption of the electric fan and the speed of the fan blade is proportional, such as 400 mm electric fan, with a fast gear power consumption of 60W, the use of slow gear, only 40W, the fastest gear of the same electric fan and the slowest gear of the power consumption difference of 40%, the power consumption of one hour on the fast gear can be used on the slow gear Nearly 2 hours. Usually open the fast gear first, cool down and use the slow gear more, you can reduce the power consumption of electric fans.
The position of the blowing fan should be well placed
In use, the fan is best placed next to the door or window. This will facilitate air circulation, improve the cooling effect, shorten the use time and reduce power consumption.
