Is Freon a liquid or a gas? Is Freon poisonous?

When it comes to freon, many people may not understand it, but if it is the main material for air conditioning and refrigeration, many people may have the impression that the main function of freon is to use for air conditioning, cooling and heating. Many owners are very concerned about whether Freon is liquid or gas. In fact, Freon is very common in ordinary times, so now many people are worried about Freon is toxic, and then the editor will bring you a related introduction to Freon.

Is Freon a liquid or a gas?

It depends on the specific operating conditions at the time and the air conditioning effect after adding freon to the air conditioner. If the cooling effect is good after freon is added to the air conditioner, it can be said that freon is added. Recall whether the freon cylinder is upright or upside down when adding freon. If the air conditioner is added upright, it should be gaseous freon, and if it is upside down, it should be liquid. The effect of gaseous and liquid Freon is the same. By the way, Freon is a bit like a lighter gas. When compressed, it is a liquid, but when it is released, it is a gas. Freon used in household air conditioners does not become liquid until minus 40 degrees below atmospheric pressure.

Is freon poisonous?

1. Freon, also known as Freon, whose name is derived from the English Freon, is a refrigerant trademark registered by DuPont. In China, there are differences in the definition of Freon. It is generally defined as the general term for halogenated substances of saturated hydrocarbons (mainly methane, ethane and propane). According to this definition, Freon can be divided into four categories: CFC, HCFC, and HFC; some scholars Define Freon as a CFC refrigerant; in some materials, Freon only refers to dichlorodifluoromethane (CCl? F?, that is, R12, a kind of CFC).

2. Freon is a colorless gas or volatile liquid at room temperature, odorless or slightly odorless, non-toxic or low-toxic, and chemically stable.

3. Freon in the air conditioner generally uses R22. It is a non-toxic, odorless, non-burning, non-explosive gas, but it will produce phosgene when it encounters an open flame, which is harmful to the human body. Once leaked, if there is no open flame, it will generally not cause harm to the human body.

4. It can be seen that the freon in the air conditioner can be used with confidence, but freon is afraid of open flames, so when the air conditioner leaks fluorine, please remember to cut off the open flame.

5. Generally speaking, Freon is a non-toxic and odorless gas. Freon in air conditioners can be used with confidence; however, Freon is afraid of open flames. Therefore, you must pay attention to the phenomenon of fluorine leakage in air conditioners. Repair the air conditioner leakage of fluorine failure, and keep the open flame away from the area where the Freon leaks. If there is a wrong understanding of the toxicity of Freon before, I hope that the analysis and introduction of the toxic components of Freon will change everyone's wrong understanding of Freon, so that you can use air-conditioning Freon with confidence.

Is freon a liquid or a gas, from the above we can know that freon can be said to be liquid or gas, because it releases gas, and at a specified temperature It is in a liquid state. Regarding the toxic problem of Freon, the editor can only say that Freon is easy to use in the process of use, and it will not cause any harm to the human body. So everyone can use Freon with confidence.
