19 ° C volatilization is more than three times the higher the temperature, the more intense Among the many factors affecting home air quality, formaldehyde can be said to be the top of the hazard, especially in the family who just moved into a new home in the summer and bought new furniture. Formaldehyde is like an invisible "killer", which will affect it unconsciously. To the health of people. Song Guangsheng, director of the National Indoor Environment and Indoor Environmental Product Quality Supervision and Inspection Center, told the reporter: "From the statistics of home environment testing, the over-standard situation of formaldehyde is picking up. The average rate of formaldehyde over-standard in newly renovated houses in the country has reached 69.7%, 60 times that of 5 years ago. % has risen significantly." In addition to formaldehyde has become a problem that must be taken seriously in new homes. For the understanding of formaldehyde, the general consumer has a misunderstanding that there is no obvious pungent smell in the room, and the harm naturally disappears. In fact, the volatilization period of formaldehyde is generally 3-15 years. It is a long-term volatilization process, which will volatilize or lurk with temperature changes and is not easily noticeable. It should be noted that the experiment found that the formaldehyde volatilization point is 19 ° C, and the temperature rises by 0.4 times for every degree of temperature rise, especially in the summer when the temperature rises more strongly and the concentration will exceed the normal three times. In the case of low average temperature in winter, the volatilization of formaldehyde is not very active, and formaldehyde is almost accumulated in the building materials. Therefore, there will be a situation where the indoor air quality is qualified in the winter and the formaldehyde is exceeded in the summer. This is because formaldehyde crouches during the winter and the temperature rises to 19 ° C and higher after the summer temperature. In addition, in summer, the temperature is high, people often turn on the air conditioner to cool down and close the doors and windows, which also affects the diffusion of formaldehyde to the outside. The reporter learned that in the past people often used "traditional methods" such as postponing staying, window ventilation, placing green plants, activated carbon, and grapefruit peel to remove formaldehyde. In this regard, Song Guangsheng told reporters: "Window ventilation is indeed a more effective way, with half a year to a year or so, can play a good effect, but also need to take into account the weather factors, such as sand, haze and other weather Under the conditions, it is not suitable for window opening. The placement of grapefruit peel is only to cover the smell of formaldehyde, and can not really play the role of removing formaldehyde."

As the weather gets hotter, the air-conditioning market has also entered the peak season. At present, in addition to adjusting the basic functions of indoor temperature, air conditioners have gradually become an important tool for people to adjust air quality, returning to the origin of "air conditioners". The reporter noted that some home appliance companies, such as Haier, have added air-conditioning functions such as formaldehyde to air-conditioning products. Can air conditioning be more effective than traditional methods to remove formaldehyde? What should I pay attention to when purchasing such air-conditioning products? This reporter interviewed relevant experts to find the answer.
