CSA-B52 Mechanical Refrigeration Code

Introduction to CSA-B52 Mechanical Refrigeration Code

• The most recent edition of the CSA-B52 Mechanical Refrigeration Code is not specified, but CSA-B52-13 is mentioned as a specific edition.

Purpose and Scope of CSA-B52

• The purpose of the CSA-B52 Mechanical Refrigeration Code is to establish minimum requirements for the design, construction, and operation of mechanical refrigeration systems.
• The code does not cover refrigeration systems used for air conditioning of buildings.

Refrigerants and Pressure Relief

• R-22 is not typically used in new installations according to CSA-B52.
• For pressure-relief protection of refrigeration system pressure vessels, the ASME Boiler and Pressure Vessel Code should be followed.

Machinery Room Design

• A Type II machinery room is designed as an unoccupied space with restricted access.

Maintenance and Operation

• The owner of the refrigeration system is responsible for ensuring that maintenance is done by a certified person.
• If no operation and maintenance manual exists, maintenance should be done in accordance with the manufacturer's instructions or a certified person's recommendation.

Informative Annexes
