Overview

EN 1117:1998 is a European Standard published by CEN that defines uniform test procedures for series-produced liquid cooled refrigerant condensers (heat exchangers) operating with a primary refrigerant. The standard’s primary purpose is to provide consistent methods to determine performance parameters - enabling reliable comparison, product identification and quality control. EN 1117 explicitly excludes technical safety requirements; it focuses on measurement and reporting of performance data only.

Key Topics

This standard covers the following technical topics and requirements:

• Product identification - clear designation and documentation needed to identify tested condenser models.
• Capacity measurement - accepted methods to establish the condenser’s heat rejection or cooling capacity under specified conditions.
• Liquid flow rate - procedures to measure and report the coolant (liquid) mass or volumetric flow through the condenser.
• Liquid-side pressure drop - standardized measurement of pressure loss across the condenser on the liquid side.
• Test conditions and reporting - defined test conditions and data presentation to ensure repeatable, comparable results across manufacturers and test labs.

Note: The standard applies to series-produced units and is intended for performance evaluation rather than safety compliance.

Applications

EN 1117 is practical for:

• Manufacturers of liquid-cooled refrigerant condensers for product development, factory testing, and performance declarations.
• Independent test laboratories performing performance verification and capacity certification.
• HVAC&R system designers and specifiers who require standardized performance data for equipment selection and system modelling.
• Procurement teams and consultants needing comparable performance figures for tendering and supplier evaluation.
• Quality assurance and R&D groups using consistent test methods for production acceptance, troubleshooting and design optimization.

Using EN 1117’s uniform test procedures helps ensure accurate data on capacity, liquid flow rate, and liquid-side pressure drop, which are critical inputs for system sizing, pump selection and energy-efficiency assessments.

Related Standards

For broader context, consult other CEN and international standards covering heat exchanger testing, refrigerating technology and component safety. EN 1117 addresses performance measurement specifically and should be used alongside applicable safety, installation and refrigerant-specific regulations when designing or certifying refrigeration systems.
