Daikin expert and doctor Truong Huu Khanh said that air conditioning is an achievement of technology, bringing comfort to life and good for health, if used correctly.
Air conditioners (air conditioners) have become familiar appliances for many families. However, some people still wonder that using air conditioners can cause respiratory diseases; Children or people with Covid-19 should not use air conditioners… These concerns were answered in the seminar “Choosing and using good air conditioners for health” broadcast live on the VnExpress fanpage on the evening of October 10. 3, attracting thousands of interested readers to follow and send questions about the program.
At the beginning of the seminar, Dr. Truong Huu Khanh, former head of the Department of Infection – Neurology, Children’s Hospital 1, Ho Chi Minh City, highly appreciated the benefits that air conditioners bring. He believes that the product needs to be convenient, easy to use, save electricity, bring good sleep and comfort to users.
According to the doctor, air conditioning was invented from the human need to live in a comfortable space regardless of whether the weather outside is hot or cold. “The progress of science and technology has compensated for our comfort. We need to have a suitable body temperature. In fact, overheating the body may not be able to adapt and can also get sick. certain diseases”. The doctor cited as being too hot, children may have anorexia, adults can’t sleep, people with sinus problems may be worse.
The doctor said that at the time of the change of season, young children often have breathing problems, many parents often ask him if he should use air conditioners for their children. “Children must have comfort to sleep well. We think that the temperature in the room using the air conditioner is only cool for adults but cold for children is wrong because everyone’s body temperature is the same. If it’s too hot, it’s wrong. If your baby can’t eat it, you should put it in a cold room when eating. However, you shouldn’t let your baby play all day in an air-conditioned room,” the doctor advised.
In the context of Covid-19 being complicated, every day the country records hundreds of thousands of positive cases, so many readers send to Doctor Truong Huu Khanh questions about using air conditioners during the epidemic. . The doctor said that many people worry that their neighbors have F0, their house is facing the hot air conditioner in their house, not knowing if the virus will run from the cold unit to the hot one. In fact, cold air only circulates in that room, not to mention the hot block is so hot that the virus cannot survive. “And if I’m F0 in that air-conditioned room, then that virus is mine too, I can’t add it,” the doctor said.
Dr. Khanh further shared, the advice “when you have Covid-19 or the flu, you need to keep warm” is for people in temperate countries, where the temperature is around 10 degrees Celsius. In Vietnam, the temperature is often higher than 30 C degrees do not need to keep warm anymore, so Covid-19 patients can safely use the air conditioner. “If you’re sick and you still have to endure heat, it’s very hard,” the doctor said.
About how to use the air conditioner for good health, according to Dr. Khanh, it is important not to let the wind blow directly to the body, not to let the temperature be too cold, the range of 25-27 degrees Celsius is suitable for both the elderly and the young. em. If you are afraid that the air conditioner will cause dry skin, you can put a basin of water in the room. It is recommended to maintain the machine regularly to get clean air in the room.
Answering the question of a reader in Ho Chi Minh City whether air conditioners produce bacteria, Mr. Nguyen Quoc Anh, Senior Manager – Technical Support Department – Daikin Vietnam said that the nature of the machine does not generate viruses, bacteria. bacteria, but they will follow the air into the indoor unit and reside in it. In addition, in the process of cooling the room air, water will condense in the indoor unit, multiplying and accumulating harmful substances. If the machine does not have the function of filtering air, killing bacteria, mold and is not cleaned regularly, it will affect the respiratory health of the family in the long run.
Currently on the market, there are many air conditioners with air purification technology such as PM2.5 filter, Plasma ion… Daikin’s own exclusive Streamer technology is mounted inside the indoor unit of the air conditioner, helping to decompose viruses. , harmful bacteria by means of oxidative decomposition. Compared with traditional plasma discharge technology, the current generated by Streamer is estimated to be 1,000 times faster, equivalent to a thermal power source of up to 100,000 degrees Celsius, so the effectiveness of inactivating bacteria and viruses is also high. than. “Streamer was previously only used on high-end Daikin lines, made in Japan, so the price is a bit high for the Vietnamese market. Recently, Daikin has introduced this technology into more popular lines, like FTKZ, FTKY are suitable for Vietnamese consumers’ prices,” said Mr. Quoc Anh.
Daikin also adds a “moisture-proof” mode to help dry the indoor unit. When the machine is turned off, the fan inside the indoor unit still runs for about 1 hour to dry all the remaining steam inside, reducing the growth of mold and unpleasant odors.
“As Dr. Khanh just said, bacteria and viruses only develop when they exist in the human body. When they exist in the external environment, they are usually very weak. We should destroy it right from the outside,” said Mr. Quoc. He emphasized.
In order to solve the problem of air conditioning blowing directly on people causing dry skin or sneezing when using, Daikin expert said that now manufacturers have put in a lot of technology to serve life. . For example, using the Coanda physical phenomenon, air conditioner manufacturers create a perforated air outlet and the wind travels along the ceiling, spreading evenly throughout the room, not blowing directly on people, limiting sore throats. The previous generation air conditioners all sucked moisture in the air, making the air in the room dry, and users were prone to dry skin. Recently, Daikin air conditioners are equipped with Hybrid Cooling technology capable of regulating and balancing humidity at an optimal level of 55% – 65%, retaining humidity for users.
Sharing about the basic knowledge when choosing to buy an air conditioner, Mr. Quoc Anh said, first you need to choose an air conditioner that is suitable for your room space, for example, a room with an area of 9-12m2 needs an air conditioner. 1 HP capacity. A small room with a large capacity machine will cause power consumption or vice versa, a large room with a small capacity machine will cause the machine to operate at too much capacity and be less durable. Choose an inverter air conditioner, the higher the number of energy stars and the energy efficiency index (CSPF), the more power you will save.
Mr. Quoc Anh noted that in order for the machine to be durable, save electricity and good for health, when using the air conditioner, do not let the temperature difference between the indoor and outdoor air conditioners exceed 5 degrees Celsius; If you don’t turn on the machine during the day, you should open the window to let fresh air into the room; and should maintain the machine regularly. Users can download the Daikin Vietnam app, schedule an appointment for Daikin staff to clean the machine, which includes a sterilization package and clean the indoor unit with hot steam.
