Accredited performance testing per PN-EN 13771 — cooling capacity (Q0), drive power (P) and COP for compressors and condensing units.
AB 308
ILAC MRAThe refrigeration compressor drives the working-fluid circuit — raising suction pressure and delivering vapour to the condenser. Laboratory measurement of Q0, P and COP verifies manufacturer declarations, supports system optimisation and documents performance for market requirements.
COCH Kraków operates specialist test benches under PCA AB 308 accreditation (ISO/IEC 17025:2017) with ILAC MRA recognition. The accredited displacement range is 5–30 m³/h for single-stage refrigeration compressors (PN-EN 13771-1) and condensing units (PN-EN 13771-2).
We measure cooling capacity by Methods A, C and E (compressors) or A and E (units), and drive power by direct measurement. Results feed catalogue data sheets, CE / Ecodesign files and OEM comparative testing.
All measuring equipment is calibrated and metrologically traceable. Tests reproduce controlled temperature and pressure conditions representative of real operation.
Accredited measurements of cooling capacity, drive power and COP for compressors and condensing units per PN-EN 13771.
According to the PCA AB 308 scope, we determine cooling capacity and drive power of single-stage refrigeration compressors and condensing units with displacement from 5 to 30 m³/h.
Measurement of refrigerating capacity under defined evaporation and condensation conditions — Methods A, C and E per PN-EN 13771-1; Methods A and E per PN-EN 13771-2.
Direct measurement of electrical power drawn by the compressor or condensing unit under stabilised operating points.
Coefficient of Performance COP = Q0 / P for compressors and complete condensing units — comparable catalogue and Ecodesign documentation.
Accredited scope covers single-stage refrigeration compressors and condensing units with compressor displacement from 5 to 30 m³/h.
Performance testing of refrigeration compressors: cooling capacity, drive power and derived efficiency indicators under controlled refrigerant conditions.
Performance testing of air-cooled and water-cooled condensing units: unit cooling capacity, drive power and system COP.
Tests cover hermetic, semi-hermetic and open compressors used in commercial refrigeration, cold rooms, ice makers and HVAC applications.
Assessment of control and protective accessories, operational stability and compliance-oriented risk review supporting manufacturer documentation.
Schematic of a compressor condensing unit with main components marked.
Forced or gravity airflow — common in smaller commercial units.
Used in larger systems with higher refrigerating capacity.
From inquiry and bench preparation to stabilised EN 13771 measurements and the accredited report.
