Which code specifically regulates mechanical refrigeration?

The code that specifically regulates mechanical refrigeration is CSA B-52. This standard provides comprehensive guidelines regarding the design, installation, operation, and maintenance of refrigeration systems. It addresses safety considerations and best practices to ensure the reliable and efficient operation of refrigeration equipment.

CSA B-52 is essential for understanding the specific requirements for various refrigeration systems and complies with safety regulations to minimize risks associated with refrigerants and equipment failures. It also outlines aspects related to the handling of refrigerants, which is crucial given the environmental considerations linked to certain refrigerants.

In contrast, ASME Section I applies to power boilers, focusing primarily on steam and hot water boilers. ASME Section IV relates to heating boilers, ensuring safety and performance standards for hot water heating systems, but does not cover refrigeration. CSA B-51 addresses the use of pressure vessels and piping, which may intersect with refrigeration systems, but it does not provide the specific regulations that CSA B-52 does.
