The refrigeration function of the air conditioner mainly relies on the refrigerant difluoromethane. Difluoromethane is odorless and non-toxic at room temperature, and generally has little effect on the human body. However, it is a flammable gas, and after being highly volatile, it may quickly form a high-concentration gas environment in an unventilated place or in a closed space, reducing the air pollution. oxygen content. If a large amount of high-concentration difluoromethane is inhaled in a confined space, it will cause the following hazards to the human body: 1. Eye irritation, causing dermatitis; 2. Lack of oxygen leads to dizziness, drowsiness, nausea, vomiting, unresponsiveness, and severe cases will lose consciousness and death.
How to avoid air-conditioning refrigerants causing disasters?
When the air conditioner is turned on, in order to save electricity, people generally close the doors and windows. As everyone knows, it is easy to cause air not to circulate. Therefore, even if the air conditioner is turned on, you should always open the windows for ventilation. If you find that the air conditioner is running normally at home, but the indoor unit does not blow out cold air, you should consider the failure of the refrigeration system and the leakage of refrigerant. At the same time, if you feel unwell and have difficulty breathing in the air-conditioned room, you should immediately turn off the air conditioner, open the doors and windows for ventilation, and contact professionals for home inspection.
What should be paid attention to when using the air conditioner
In addition to difluoromethane, there are many mites, molds, legionella, staphylococci, etc. in the air conditioner, which can easily lead to allergies, asthma, and even respiratory tract infections, which can be life-threatening in severe cases. To this end, the following protective measures should be taken.
1. Difluoromethane leakage is generally caused by improper operation during the installation of new air conditioners or the maintenance of old air conditioners. If the refrigeration effect is not good after installation or maintenance, and the above symptoms appear, contact professionals in time for on-site inspection.
2. The air conditioner must be cleaned before use, including the filter screen, heat sink, etc. Central air-conditioning should also be regularly tested and disinfected with professional agents.
3. After entering the room from the outside in summer, do not immediately adjust the temperature of the air conditioner too low. When using the air conditioner, the temperature should be adjusted to about 26°C, and the dehumidification function can be used reasonably during the rainy season.
4. Do not close the doors and windows when you first turn on the air conditioner. Ventilate for a period of time to facilitate the distribution of bacteria and mites in the air conditioner. Appropriate breaks during use, open windows for ventilation.
5. People who work and live in air-conditioned rooms for a long time should increase outdoor activities and breathe fresh air.
6. The air outlet of the air conditioner should not blow on the human body, especially not on infants and the elderly and infirm.
