Does air conditioning not cause cancer? pass!

In recent days, a microblog has been widely republished on "Car Air Conditioning Carcinogens, Must Read!" This long Weibo explains how benzene is released and how it can harm people. It also quotes a lot of data. Many car owners suddenly feel bad. Shortly afterwards, the shell network made rumor on this rumor. However, there are also media reports that if indoor air conditioners are cleaned occasionally, they may cause a variety of diseases, and severe cases may cause lung cancer. Nandu reporter interviewed air-conditioning technicians and doctors, and also confirmed that long-term non-clean air conditioning may cause discomfort to the lungs, but there is no conclusive cause of cancer.

Net car air conditioning can be carcinogenic The microblogging long article describes the acceptable level of benzene per square foot is 50 mg. If the car is parked indoors and the window is closed, it will produce 400-800 mg of benzene. If it is parked in the open air at temperatures above 15.5°C, the benzene will rise to 2000-4000 mg, which is more than 40 times the allowable amount. As soon as people enter the car and the windows are closed, they will inevitably quickly inhale excessive amounts of toxins.

In response to this statement, the shell network also published in the full text of the American Cancer Society rumors of this rumors, the study found that the benzene is mainly from the fuel, rather than rumors from the dashboard and other components of the car. In addition, the "acceptable level of benzene 50 mg" is completely untenable. The content of chemical substances in gases is applied in units of cubic feet rather than square feet of area.

Indoor air conditioning can also cause cancer?

After a wave of waves and waves, the car air-conditioning carcinogenic theory was refuted by the shell network and other falsifications. It was also reported by the media that indoor air conditioners may cause a variety of diseases if they are cleaned occasionally for a long time. Severe cases may also cause lung cancer. Caused many people's concerns. Nandu reporters interviewed experts in respiratory medicine and learned in the home appliance industry that long-term non-cleaning of air conditioners may cause discomfort to the lungs and cause various diseases, but there is no scientific basis for cancer.

Doctor: There are no conclusive arguments for the cause of cancer. According to Zhou Hong, deputy chief physician of respiratory medicine at the Fifth Affiliated Hospital of Sun Yat-sen University, the problem of respiratory diseases caused by air conditioning has been prominent in Zhuhai. Zhuhai air humidity is relatively high. After the air-conditioning filter is contaminated with water, it is easier to absorb dust and it is easier to breed bacteria and dust mites. Some people with allergic constitution and poor immunity will appear after breathing such air. Allergic reactions, severe cases can also cause lung irritation, respiratory disease.

Every year when air conditioners are used, the number of patients suffering from rhinitis and asthma caused by the use of air conditioners will increase significantly. Air pollution, car exhaust, dust, etc. may cause lung discomfort, but it is unscientific to occasionally clean air conditioners as a cause of lung cancer.

The true cause of cancer is not yet clear in the medical field.

Industry: air conditioners do have to be washed regularly According to Wei Shenbao, Suning Appliance's Zhuhai Branch's after-sales service department, many users think that cleaning air conditioners only cleans air filters. In fact, filters, evaporators, condensers, and blades are required to be cleaned regularly. The evaporator should be washed at least once every 3 years.

The evaporator of an indoor air conditioner is mainly composed of a copper tube and an aluminum sheet, and is used to dissipate the cold air brought by the refrigerant into the air. Therefore, long-term alternating hot and cold, so that the condenser will often be attached to the water droplets, it is easy to breed bacteria and aphids.

Generally speaking, the evaporator needs to be cleaned after 3 years of use. It is best to use professional potters to clean the potions with bactericidal and anti-caries. The families that keep pets are advised to wash once a year. Because the air conditioning evaporator cleaning requires some technology.

The condenser must also be cleaned regularly, otherwise it will affect the service life of the air conditioner, and the power consumption will also increase.

The filter is the easiest part to clean. Users can do it by themselves. Just open the air conditioner's housing, pull out the filter, and rinse it with a faucet or shower on the back of the filter. In principle, it is recommended that the home air conditioner be cleaned every month. Once filter.

In addition, as long as the fan blade can be scrubbed with a damp cloth, it is also very simple. At present, the cost of thoroughly cleaning an air conditioner in the market is around 80 yuan.
