Good scenery home news news Health air conditioning can clean indoor air pollution? Many air-conditioning manufacturers are focusing on health and environmental protection signs, and are rushing to launch healthy air conditioners that claim to remove indoor harmful gases such as formaldehyde and benzene. In this regard, some experts and consumers have raised questions. The following good scenery home for you to answer.
Healthy air conditioning collective attack
An air-conditioning brand sells a light-wave health air conditioner, propagating that the air conditioner uses nano-scale photocatalyst air purification technology, which can directly decompose harmful gases such as formaldehyde in the air at normal temperature. Sales staff said that this air conditioner is stylish and healthy, and most of the buyers are young people and fashion people.
Another manufacturer has specially introduced a healthy air conditioner with a purification chamber. The instructions indicate that the ceramic filter in the purification chamber contains nano-scale microporous manganese catalyst, which can adsorb and decompose harmful gas molecules in the air. The product introduction also lists the test report of the national environmental protection inspection department, indicating that the formaldehyde removal rate is 64% and the ammonia removal rate is 54% in a certain gas concentration and time. According to the salesperson, this kind of air conditioner is the special technology of the brand. After the launch in the second half of last year, it has attracted the attention of many consumers.
In addition, the use of activated carbon is also a method used by many manufacturers to purify indoor air. The harmful gas such as formaldehyde in the air is adsorbed on the filter net by the adsorption of activated carbon.
Consumers will be suspicious
In the air-conditioning sales area of ​​a home appliance store, Ms. Zhao and her husband are consulting a brand of healthy air conditioners. Ms. Zhao has just renovated a new house at the end of last year. The child is young and should try to reduce indoor air pollution. If the air conditioner has the function of removing toxic gases, she is happy to buy it.
Ms. Zhao said that many air conditioner manufacturers are selling healthy air conditioners, and the introduction of purification technology is also different. Can the purification equipment in the air conditioner really work? Ms. Zhao did not understand much about these issues.
It is difficult to purify the air
A staff member of the air-conditioning technology development department of a home appliance company in Qingdao said that adding air-purifying equipment to the air conditioner to remove harmful gases from the air can be realized technically. However, the technologies and processes used by various manufacturers are different, and the conditions in practical applications are also complicated, and it is difficult to determine how much it can play.
Professor Gao Canzhu from the School of Environmental Science and Engineering of Shandong University specializes in indoor air pollution control research. He expressed the same point of view: technology is right, the effect is difficult to say.
Professor Gao believes that nanophotocatalyst technology requires high light, and it can decompose formaldehyde and other gases in the air under strong ultraviolet radiation. The intensity of ultraviolet light in the room is small, and in general, the photocatalyst is difficult to react. Nano-manganese catalyst technology uses manganese as an oxidizing substance to decompose formaldehyde and benzene gas molecules through chemical reaction. It is not easy to achieve suitable catalytic conditions in an indoor environment. Professor Gao said that activated carbon can absorb a part of harmful gases, but it should be replaced in time after using it for a period of time. Otherwise, if the concentration of gas adsorbed on activated carbon is too high, it will be released into the air.
