Külmutusaineks

Külmutusaineks is the Estonian term for refrigerant. Refrigerants are working fluids used in refrigeration and air conditioning systems to absorb heat from a space and transfer it elsewhere. This process is fundamental to technologies that cool our food, keep our homes comfortable, and enable various industrial processes. Külmutusaineks are typically liquids or gases that undergo a phase change, absorbing heat during evaporation and releasing heat during condensation.

Historically, various substances have been used as külmutusaineks, including ammonia, sulfur dioxide, and chlorofluorocarbons (CFCs). However, due to environmental concerns such as ozone depletion and global warming, many older refrigerants have been phased out or are being replaced. Modern systems increasingly utilize hydrofluorocarbons (HFCs), hydrofluoroolefins (HFOs), and natural refrigerants like propane or CO2, which have lower global warming potentials. The selection of an appropriate külmutusaineks depends on factors like the application, desired operating temperature, safety requirements, and environmental regulations. Research and development continue to focus on finding even more efficient and environmentally benign cooling solutions.
