What is refrigerant R-718?

Refrigerant R-718 is the designation for water when used as a refrigerant. It is considered a natural refrigerant due to its environmentally friendly properties, and it is non-toxic and non-flammable, making it safe for use in various applications. Water is unique in its ability to absorb heat effectively and can be utilized in both vapor-compression and absorption refrigeration systems.

Unlike synthetic refrigerants, which can have implications for global warming and ozone depletion, water does not pose these environmental risks, making it a sustainable choice for cooling systems. It is commonly used in large-scale applications such as district cooling systems and industrial refrigeration processes due to its favorable thermodynamic properties.
