Air conditioners use refrigerants to carry heat between the indoor and outdoor units. In the late 1970s, it was discovered that CFC and HCFC fluorocarbon gases, which were the most common refrigerants of that time, deplete the ozone layer if released into the atmosphere. Since then, Daikin, as a manufacturer of fluorocarbon gas, has been working to find refrigerants that exert as little impact as possible on the environment. Let's look at air conditioner refrigerants as they relate to global warming and ozone layer depletion.

Just how much of an impact do refrigerants (fluorocarbons) have on the environment? Here we will explain the figures used to show degree of impact as well as the varying degrees of impact. |

Are there any refrigerants that don't impact the environment? Let's look at a few substances that could possibly be used as refrigerants. |
