What is the refrigerant code name for water?

The refrigerant code name for water is represented as R718. Water is utilized in various industrial applications as a refrigerant due to its non-toxic and environmentally friendly properties. In refrigeration cycles, it is primarily employed in absorption refrigeration systems and is also capable of functioning in certain vapor-compression systems, although less commonly.

Understanding this classification is important for recognizing how different substances function in cooling applications. Other options like R123, R744, and R134a correspond to different refrigerants primarily used in mechanical refrigeration systems, which include synthetic compounds specifically designed for efficient thermodynamic properties in cooling systems. R744, for instance, is carbon dioxide, while R134a is a common fluorocarbon refrigerant. However, they all have distinct chemical compositions and applications that differentiate them from water, reinforcing the unique status of R718 as a refrigerant code for water.
