The term “refrigerating system” used in this European Standard includes heat pumps. This part of EN specifies the classification and selection criteria applicable to refrigerating systems. These classification and selection criteria are used in parts 2, 3 and 4. ISO ; 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 Annex E of this European Standard are not covered by this standard.

Annex C specifies how to determine the amount of refrigerant permitted in a given space, which when exceeded, requires additional protective measures to reduce the risk.

Annex E specifies criteria for safety and environmental considerations of different refrigerants used in refrigeration and air conditioning. This standard is not applicable to refrigerating systems and heat pumps 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. 3781

This standard 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 standard also applies in the case of the conversion of a system to another refrigerant type, in which case conformity to the relevant clauses of parts 1 to 4 of the standard shall be assessed.

Product family standards dealing with the safety of refrigerating systems takes precedence over horizontal and generic standards covering the same subject.

This Part 2 of this Standard is applicable to the design, construction and installation of refrigerating systems including piping, components and materials.

It includes ancillary equipment not covered in FprEN 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, eh, fan motors, electrical motors and transmission assemblies for open compressor systems. ISO ; 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.

This standard does not apply to goods in storage. This standard 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 Part 3 of the European Standard is applicable to the installation site plant space and services. It specifies requirements on the site for safety, which may be needed because of, but not di connected with, the refrigerating system and its ancillary components.

Systems using refrigerants other cin those listed in of FprEN This standard also applies in the case of the conversion of a system for another refrigerant type, in which case conformity with the relevant clauses of parts 1 to 3778-1 of the standard shall be assessed. This 37-1 does not cover “motor vehicle air conditioners” constructed according to product standards such as ISO Systems using refrigerants other than those listed in FprEN This standard is not applicable to refrigeration systems and heat pumps 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 Part 4 of the European Standard specifies requirements for safety and environmental aspects in relation to operation, maintenance, and repair of refrigerating systems and the recovery, reuse and disposal of all types of refrigerant, refrigerant oil, heat-transfer fluid, refrigerating system and part thereof.

These requirements are intended to minimise risks of injury to persons and damage to property and the environment resulting from improper handling of the refrigerants or from contaminants leading to system breakdown and resultant emission of the refrigerant. Information on cookies usage.
