What is the primary concern when selecting refrigerants for commercial refrigeration?

The primary concern when selecting refrigerants for commercial refrigeration revolves around their environmental impact and safety. The refrigerants used in commercial systems can contribute to ozone depletion, global warming potential, and overall environmental degradation if not chosen wisely.

Regulations, such as those imposed by the Environmental Protection Agency (EPA) in the United States, have led to a push for more environmentally friendly refrigerants, which may have lower global warming potentials or zero ozone-depleting properties. Additionally, safety is also a critical factor, as some refrigerants can be flammable or toxic, posing risks to those who operate or maintain refrigeration systems.

Thus, while factors such as cost, brand reputation, and availability of service technicians are important considerations in the overall selection process, they are secondary to ensuring that the refrigerant aligns with environmental regulations and safety standards. This prioritization reflects the industry's commitment to sustainable practices and responsible environmental stewardship.
