As a result, ammonia is considered to be one of the most environmentally-safe refrigerants available to the public. Why is Ammonia a Good Refrigerant?Īmmonia occurs naturally in the environment as a bacteria in water and soil before it is released into the air as vapors which dissipate and react with moisture. Ammonia’s unique properties make it an ideal refrigerant for large industrial refrigeration systems. The physical properties of the refrigerant determine the temperature ranges and pressures in the system. The compression/expansion process lowers and raises the temperature of the refrigerant.Ĭoordinate this process perfectly in a controlled system and you master temperature. The refrigerant is a vapor most of the time but is periodically compressed to become a liquid, then allowed to expand back into vapor. A refrigerant is charged with the responsibility of moving heat energy from one place to another. The typical industrial refrigeration system is a vapor-compression refrigerator. How does an Ammonia Refrigeration System work? The growing concern for environmental impact and F-gas regulation has pushed refrigeration technicians towards natural alternatives like ammonia and carbon dioxide refrigerants. Ammonia has been established as the refrigerant of choice in the food preservation business due to its unmatched thermodynamic properties.
