Refrigerating systems and heat pumps - Safety and environmental requirements - Part 2: Design, construction, testing, marking and documentation
Abstract
This document specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants. The term "refrigerating system" used in this document includes heat pumps. This document is applicable to the design, construction and installation of refrigerating systems including piping, components and materials. It includes ancillary equipment not covered in prEN378-1:2026, prEN 378-3:2026 or prEN 378-5:2026 which is directly associated with these systems. It also specifies requirements for testing, commissioning, marking and documentation. Requirements for secondary heat transfer circuits are excluded except for any protection requirements associated with the refrigerating system. Ancillary equipment includes, for example, fans, fan motors, electrical motors and transmission assemblies for open compressor systems. This document applies: a) to refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard, e.g. [1]; b) to secondary cooling or heating systems; c) to the location of the refrigerating systems; d) to replaced parts and added components after adoption of this standard if they are not identical in function and in the capacity. Systems using refrigerants other than those listed in prEN 378-5:2026 are not covered by this document. This document does not apply to goods in storage. This document is not applicable to refrigerating systems which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication. This document is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for existing stationary systems, being transferred to and operated on another site. This document also applies in the case of the conversion of a system to another refrigerant type.
