Which refrigerant is most commonly associated with the designation R-717?

The designation R-717 refers specifically to ammonia, which is widely used as a refrigerant in various cooling applications, particularly in commercial and industrial settings. Ammonia is prized for its excellent thermodynamic properties, which make it highly efficient for refrigeration cycles. It has a high latent heat of vaporization, allowing it to absorb significant amounts of heat during the evaporation process.

Ammonia is also known for being eco-friendly, as it does not contribute to ozone depletion or global warming, making it an attractive choice in an era focused on sustainable practices. Its use is particularly prevalent in large-scale systems such as those found in food processing, refrigeration plants, and cold storage facilities.

In contrast, other refrigerants like Freon (a brand name for various refrigerants primarily containing chlorofluorocarbons or hydrofluorocarbons) and hydrocarbons like butane and propane have different chemical properties and applications that do not align with the designation R-717.
