Group A3, B2, or B3 refrigerants with a total prime mover nameplate rating of 25 kW or moreĪ refrigeration system design must consider operational and maintenance hazards.

Group AI, A2, or B1 refrigerants with a total prime mover nameplate rating of 125 kW or more.

From the PEBPVRSR Safety Regulation, design registration is required to all refrigeration systems under the following:.

Note that pressure piping registration for NPS 3 exemptions from the PEBPVRSR Safety Regulation 84 (2)(a) still applies to all refrigerant pressure piping and the existing requirements remain unchanged.

CSA B51 Clause 5.1.2 and 5.1.3 remains unchanged and requires registration.

CSA B52 Clause 5.5.1 determines a regulated refrigeration system shall meet a minimum design pressure of 103 kPag (15psig) and shall be not less than the pressure-temperature saturation limits contained within this Clause.

CSA B52 Clause 5.3.1 requires registration and acceptance to the regulatory authority of the “refrigeration system.”.

Refrigerants are fluids that expand and compress, and undergo phase change during pressure or temperature fluctuations.

Designs are required to be submitted to the Provincial Safety Manager, Engineering for registration before installation.

Adoption of CSA B52 and B51 and the regulation requirements in Section 88 and 84 of the PEBPVRSR Safety Regulation requires design registration of pressure equipment and regulated refrigeration systems.
