(Amendment)Refrigerating systems and heat pumps - Safety and environmental requirements - Part 3: Installation site and personal protection
Refrigerating systems and heat pumps - Safety and environmental requirements - Part 3: Installation site and personal protection
This European Standard 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 European Standard includes heat pumps.
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 directly connected with, the refrigerating system and its ancillary components.
This standard 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. ISO 13043;
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 of FprEN 378-1:2016, Annex E are not covered by this standard.
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 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 for another refrigerant type, in which case conformity with the relevant clauses of parts 1 to 4 of the standard shall be assessed.

Overview
EN 378-3:2016/FprA1 - "Refrigerating systems and heat pumps - Safety and environmental requirements - Part 3: Installation site and personal protection" (CEN) defines safety, environmental guidance and operational procedures for the installation site (plant space and services) of refrigerating systems and heat pumps. It applies to new systems, extensions/modifications, relocations and conversions to other refrigerants (subject to scope limits). The standard addresses risks to persons and property arising from siting, ventilation, detection and emergency measures, but excludes vehicle air‑conditioning product standards, goods in storage and systems using refrigerants not listed in FprEN 378-1:2016 Annex E.
Key topics and technical requirements
- Site classification and hazardous zones
- Assess location for flammability and classify hazardous zones per EN 60079-10-1, especially for refrigerant groups A2L, A2, B2L, B2, A3, B3.
- Refrigerant charge and occupancy
- Charge limits follow EN 378-1:2016 Annex C for access category and location class; special provisions apply when using C.3 calculations.
- Detection and alarm set‑points
- Detectors must signal at preset values and be continuously monitored; detector failure should trigger the emergency sequence.
- Preset for refrigerant detectors: not more than 25% of LFL or 50% of ATEL/ODL, whichever is lower (at 30 °C or 0 °C, whichever is more critical).
- Oxygen‑deprivation detectors preset at 18% or higher; oxygen sensors must not be used to indicate refrigerant leaks.
- Detector response time: ≤ 30 s at 1.6× preset value. Consider manufacturer sensitivity tolerance and voltage fluctuation ±10%.
- Halogenated refrigerant detectors shall comply with EN 14624; selection/use guidance references EN 60079-29-2.
- Machinery room safety
- Fire sprinkler requirements for R‑717 (ammonia): individual heads actuated at ≥141 °C, no manual override, and compliance with EN 12845; consider pre‑action systems and remote sumps to limit run-off.
- Where charge exceeds practical room limit, doors must open to outside or via an anteroom with self‑closing tight‑fitting doors to an emergency exit.
- Maintenance and modifications
- Applies to replaced parts or added components that differ in function or capacity; conversion to other refrigerants requires assessment against Parts 1–4.
Applications and users
- Intended for refrigeration and heat‑pump designers, HVAC contractors, plant builders, facility managers, safety officers, maintenance teams, and certifying bodies.
- Practical uses: siting machinery rooms, specifying ventilation and detection systems, emergency control logic, safe conversion to alternate refrigerants, and compliance during installation, repair and refrigerant recovery.
