NiedrigGWPKühlmitteln

NiedrigGWPKühlmitteln, often translated as low Global Warming Potential (GWP) refrigerants, represent a category of substances used in refrigeration and air conditioning systems that have a significantly reduced impact on global warming compared to traditional refrigerants. GWP is a measure of how much heat a greenhouse gas traps in the atmosphere over a specific period, relative to carbon dioxide. High GWP refrigerants, such as HFCs (hydrofluorocarbons), have been widely used but contribute substantially to climate change. The development and adoption of niedrigGWPKühlmitteln are driven by international agreements like the Kigali Amendment to the Montreal Protocol, which aims to phase down the production and consumption of HFCs. Examples of niedrigGWPKühlmitteln include HFOs (hydrofluoroolefins), natural refrigerants like CO2 (R744), ammonia (R717), and hydrocarbons such as propane (R290) and isobutane (R600a). Each of these has different properties and application areas. HFOs are often seen as direct replacements for HFCs in many existing systems due to their similar thermodynamic properties, though some may have mild flammability. Natural refrigerants, while having very low or zero GWP, may require system modifications due to their flammability (hydrocarbons, ammonia) or operating pressures (CO2). The transition to niedrigGWPKühlmitteln is a critical step in mitigating the environmental impact of the cooling sector.
