We all know that Freon is indispensable for air conditioning, but what do we know about Freon? Although we all know that Freon is often referred to as “fluorine”, but the composition and chemical properties of Freon is not well understood, I hope that the introduction of Freon to let you know it. Many people worry that Freon is a toxic substance, so I have made an analysis of the toxicity of Freon, and analyze the composition of Freon more clearly.
Introduction of Freon
Freon, also known as Freon, derives from the English name Freon, which is a trademark of refrigerant registered by DuPont in the United States. In China, there are differences in the definition of Freon, which is generally defined as a general term for halogen substitutes of saturated hydrocarbons (mainly methane, ethane and propane). According to this definition, Freon can be divided into 4 categories, such as CFC, HCFC and HFC; some scholars define Freon as CFC refrigerant; in some materials Freon only refers to dichlorodifluoromethane (CCl₂F₂, i.e. R12, a kind of CFC class).
Freon is a colorless gas or volatile liquid at room temperature, tasteless or slightly odorous, non-toxic or low toxicity, chemically stable.
Analysis of the toxicity of Freon in air conditioners
It is non-toxic, odorless, non-combustible and non-explosive gas, but it will produce light gas when it meets open fire, which is harmful to human body. Once it leaks, if it does not meet open fire, it will not cause harm to human body.
It is safe to use Freon in air conditioners, but Freon is most afraid of open fire, so please remember to cut off all open fire when there is a fluorine leak.
The role of Freon in air conditioners
During the working process of air conditioner, the compressor of air conditioner will inhale the gaseous Freon in the evaporator and compress it to become high temperature and high pressure gas, then the high temperature and high pressure Freon gas will be sent to the condenser through the expansion valve and after heat dissipation, the Freon will become low temperature and high pressure liquid, then the air blown out by the air conditioner is hot air. After that, the low-temperature and high-pressure Freon will go through the capillaries and enter the evaporator through the throttling of the capillaries. After entering the evaporator, the space will suddenly increase and the pressure will decrease, and the Freon will change from liquid to gas. When the fan of the indoor unit blows over the evaporator, the air blown out by the air conditioner will become cold air to achieve cooling.
In general, Freon is a non-toxic and odorless gas, and Freon in air conditioners can be used safely; however, Freon is most afraid of open fire, so we must pay attention to the phenomenon of fluorine leakage in air conditioners, and repair the fluorine leakage in a timely manner, and keep the open fire away from the area where Freon leaks. If there is a misconception about the toxicity of Freon before, I hope that the analysis and introduction of the toxic components of Freon will change your misconceptions about Freon, so that you can use the air conditioner Freon with confidence.
