Freon in air conditioners generally uses R22, which is non-toxic, odorless, non-combustible, and does not explode. It is only harmful to the human body when it encounters an open flame. Once leaked, if you do not encounter an open flame, it will generally not cause harm to the human body.
Freon is generally low-toxic or non-toxic. Leakage into the air is very harmful to the human body, but Freon will increase the greenhouse effect and aggravate global warming. At the same time, when Freon rises into the sky, it will consume ozone and increase ozone. The harmful radiation of the Sun's Earth seriously affects biological health. However, Freon leaks into the air and is not harmful to the human body. If the Freon in the air reaches 80% or more, the human body will suffocate.
