luonnonkylmäaineiden
Luonnonkylmäaineet, or natural refrigerants, are substances found in nature that can be used to transfer heat in refrigeration and air conditioning systems. Unlike synthetic refrigerants that are manufactured chemically, natural refrigerants have a lower environmental impact, particularly regarding their ozone depletion potential (ODP) and global warming potential (GWP). Common examples include ammonia (NH3), carbon dioxide (CO2), and hydrocarbons like propane (R290) and isobutane (R600a).
Ammonia is a highly efficient refrigerant with zero ODP and GWP. However, it is toxic and flammable,
Hydrocarbons, such as propane and isobutane, have very low GWPs and zero ODP. They are highly flammable,
