Which refrigerant is designated as R-718?

R-718 is the designation for water when it is used as a refrigerant. In refrigeration systems, water can absorb heat effectively, making it a practical and eco-friendly refrigerant option, especially in applications where high efficiency and low environmental impact are required. Water’s natural properties allow it to undergo phase changes (liquid to vapor and vice versa) efficiently at various temperatures and pressures, which is essential in cooling processes.

The use of water as a refrigerant avoids many environmental issues associated with synthetic refrigerants, such as ozone depletion and global warming potential. This makes it an increasingly desirable choice in sustainable design approaches for cooling systems.

Other options refer to different substances with distinct properties and applications as refrigerants but do not carry the designation of R-718.
