Overview

EN 1117:1998/A1:2002 is a CEN European standard that defines test procedures for establishing the performance of liquid‑cooled refrigerant condensers (heat exchangers). The amendment A1 (2002) updates the original 1998 standard to accommodate newer refrigerants (e.g., R404A, R407C, R410A) and adds clarifications and measurement requirements relevant for modern refrigerants and non‑azeotropic mixtures.

ICS classifications: 27.060.30 (Boilers and heat exchangers) and 27.200 (Refrigerating technology).

Key topics and technical requirements

• Scope: Performance testing methodology for liquid‑cooled refrigerant condensers (condensers used in refrigeration systems).
• Definitions added/clarified: condensing pressure, condensing (dew point) temperature, bubble point temperature, subcooling, superheat, oil content, and high glide refrigerants (defined as mixtures with >3 K difference between condensing and bubble point at 40 °C condensing temperature).
• Standard capacity (Δt) values for common refrigerants (as specified in the amendment):
  • R134a: 25 K
  • R404A: 25 K
  • R407C: 35 K
  • R410A: 40 K
  • NH3: 50 K
• Measurement and uncertainty:
  • Refrigerant mixture composition: 1% by mass uncertainty for each refrigerant component.
  • For high‑glide (non‑azeotropic) refrigerants, the mixture shall be measured unless the mass fraction is guaranteed to vary by less than 2% from manufacturer data.
• Test arrangement and equipment:
  • Ensure free drainage of liquid refrigerant to the liquid receiver.
  • Prevent accumulation of liquid refrigerant in the cycle for non‑azeotropic refrigerants.
  • Do not modify the liquid flow through the condenser under test.
  • Air recirculation should be treated the same way as in normal operation (neither artificially created nor prevented).
  • For high‑glide refrigerants the liquid receiver internal volume shall be < 4% of the total system volume.
• Manufacturer data: amendment removes previous requirement for correction factors for other refrigerants.

Practical applications

• Standardizes how condenser performance is measured for product rating, certification and comparative testing.
• Ensures test labs and manufacturers produce comparable, repeatable performance data for condensers using modern refrigerants.
• Guides HVAC‑R engineers and test rig designers on instrumentation, measurement uncertainty, and setup requirements-especially important when testing non‑azeotropic (high‑glide) refrigerant mixtures.
• Useful for compliance testing, product datasheets, and evaluation during design validation or R&D.

Who should use this standard

• Heat‑exchanger and condenser manufacturers
• Independent testing laboratories and certification bodies
• HVAC‑R design and performance engineers
• Product compliance and quality assurance teams
• Standards bodies and technical committees (CEN/TC 110)

Related standards

• Other CEN standards on heat exchangers and refrigerating technology (refer to CEN/TC 110 for related normative references and national implementations).

Keywords: EN 1117, liquid‑cooled refrigerant condensers, heat exchangers, test procedures, condensing pressure, bubble point, high glide refrigerants, R407C, R410A, measurement uncertainty.
