Which refrigerants are commonly used in commercial refrigeration systems?

In the context of commercial refrigeration systems, the correct choice encompasses common refrigerants specifically designed to meet industry standards and efficiency requirements. R-404A and R-507 are widely used in commercial applications due to their suitability for low-temperature refrigeration environments, such as freezers and cold storage systems. Both refrigerants have characteristics that make them effective for these purposes, including high efficiency in heat transfer and stability under varying operating conditions.

It is important to note that R-12 and R-22 have been phased out in many applications due to their environmental impact, contributing to ozone depletion. While R-410A and R-134A are prevalent in air conditioning and some low-temperature applications, they are not as commonly used in the commercial refrigeration sector as R-404A and R-507, which are specifically formulated for high-capacity system requirements.

Understanding the application of these refrigerants is crucial for compliance with environmental regulations and for ensuring optimal performance in refrigeration systems, highlighting why R-404A and R-507 are favored choices in commercial refrigeration settings.
