Külmgaase

Külmgaase, also known as refrigerants, are substances used in refrigeration and air conditioning systems to transfer heat from one location to another. They are designed to have a low boiling point, allowing them to absorb heat from the environment and evaporate, which then releases heat when the refrigerant is compressed and condensed. The most common types of refrigerants are hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs). However, due to their high global warming potential, the use of HFCs and HCFCs is being phased out under the Montreal Protocol and the Kigali Amendment. Alternative refrigerants, such as hydrofluoroolefins (HFOs) and natural refrigerants like ammonia and carbon dioxide, are being developed and adopted to reduce the environmental impact of refrigeration and air conditioning systems. The selection of a refrigerant depends on various factors, including the specific application, safety considerations, and environmental regulations. Proper handling, disposal, and recycling of refrigerants are crucial to minimize their environmental impact and ensure the safety of personnel and the public.
