What is an advantage of using ammonia as a refrigerant?

Using ammonia as a refrigerant is advantageous primarily because it is readily available. Ammonia, or NH3, is one of the most commonly used refrigerants in industrial applications due to its wide availability and cost-effectiveness. It is produced from natural resources and has been in use for a long time, making it a well-understood substance in refrigeration systems. This availability can lead to reduced costs and easier procurement for facilities that rely on refrigeration.

In contrast, other refrigerants might be more expensive or have supply chain limitations, making ammonia a practical choice for many industrial applications. This availability also ensures that technical expertise and support for ammonia refrigeration systems are widespread, further enhancing its usage in the industry.
